Audio expansion connectors are provided on the
rear panel for connecting multiple SP1200s, with
shared audio via balanced busing. Each of the four
program input signals are internally balanced and
can be independently assigned to the balanced bus
with internal assignment switches. The LOCAL/
REMOTE switches on the rear panel are provided for
selecting either local or bus operation for each
input. The paging mic and paging control signal are
also carried over the expansion bus.
A wired remote control is available that can be
used to select input sources and adjust volume levels
for the zone. The amplifier can be programmed with
a unique address, and two amplifiers with the same
address can be controlled by a single remote when
interconnected by means of the RS485 port. The
remote control fits into a double-gang electrical box
with a Decora®-style faceplate.
In addition, the RS485 port can interface with third-
party control systems, or a PC-compatible computer
loaded with the SPLinker software application for
computer control of up to 32 zones in a system.
An internal option slot is provided for installing an
optional DSP card (SP-DSP1). It provides additional
ambient noise sensing for the Program Inputs using
the optional ambient microphone. As the noise level
in the room increases, the gain on the selected
source gradually increases to keep the music audible
above the background noise.
2. Introduction
The SP1200 is a single-channel version of our
popular SP2400 dual-channel microprocessor-based
music controller. Having a single 200 watt power
amplifier, it's designed for use in a variety of
installations requiring high performance, flexible
features, and ease of use. Examples of such
installations are retail stores, restaurants, bars, and
theme venues. The SP1200 provides one output
that can be used for single-zone coverage. Four
stereo line-level inputs are provided on the rear
panel, along with a paging mic input and two local
mic/line inputs.
The program input sources can be independently
assigned to the zone with the Input Select buttons
on the front panel. The boxes under the Input
Select buttons are sized to accept Brother P-Touch®
labels. Each of the four inputs has an integral AGC
circuit to automatically compensate for level
differences between the input sources. Input 1 has
a buffered line-level output that may be used for
music-on-hold or other external applications.
Program Priority can be assigned to Input 4 for use
with a jukebox or alternative paging configurations.
When a signal is detected at Input 4 with priority
activated, it overrides any other program source
assigned to that channel or zone.
Each of the four input sources can be either
stereo or mono, although output from the SP1200
is a combined mono signal of both left and right
inputs. The zone has a 3-band program EQ with
sweepable mid for tuning the four program sources.
Each mic input has a 40 dB gain switch for use
with either mic or line-level signals as well as a
variable gain trim, phantom power switch, and a two-
band EQ.
In addition, the zone has a variable VOX control
for adjusting the trigger threshold of the paging mic's
ducking circuit. The paging mic operates in the zone
when voice-activated. However, it can be assigned
to operate over the entire system when manually
operated with a switch connected to the PAGING
MIC CONTROL connector.
An RS232 port (COMM PORT) is provided on the
front panel for connecting a Palm™ Handheld or
PC-compatible laptop computer for configuring the
optional DSP card.

The zone is equipped with an input for an
optional ambient microphone that can sample the
ambient noise level in the room. The microprocessor
then adjusts the paging mic gain in the zone to
compensate for increased or decreased noise
levels. This way the paging mic is always audible
above the background noise.
The Master Volume Up/Down buttons adjust the
overall level that is routed to the PRE OUT connector
(and the AMP IN connector when the jumper is
installed). Internal jumpers are provided for configuring
the amplifier outputs for 70V, 100V, or 8-ohm operation.

The Meter indicates the level at the PRE OUT
jack. Normally, it operates as a peak program meter
(PPM). When adjusting the MASTER VOLUME level,
the meter changes from level indication to level
setting indication. After five seconds, the meters
switch back to normal peak program metering.
CONTROL is a Phoenix-type connector for
connecting external normally-open switches for
remote paging. Two options are available: page to
Zone A, and page to the entire system (ALL CALL).
Connect the switches between GROUND and the
option of choice.
There are two STATUS indicators. The
OVERLOAD LED indicates when the amplifier is
beginning to current limit. The ON LED indicates
when the SP1200 is operating.
PHANTOM applies phantom power (+24V DC)
to pins 2 and 3 of the microphone input. Move
both switches to the down position to turn on
phantom power.
The COMM PORT is used to connect to the
optional DSP card with a Palm™ Handheld or PC-
compatible laptop computer for configuration.
The GAIN +40 dB DIP switch is used to set the
gain for use with either a mic-level or a line-level
signal. Move both switches to the down position for
mic-level signals, and up for line-level signals.
Turning the POWER switch on activates the soft-
start circuit in the power supply. The soft-start
circuit impedes in-rush current from the AC supply.
The GAIN variable control is used to trim the mic
preamp gain for the best signal-to-noise ratio.
The LOW variable control is a shelving filter that
provides 12 dB of boost and cut below 100Hz.
The HIGH variable control is a shelving filter that
provides 12 dB of boost and cut above 12kHz.

EXPANSION IN/OUT consists of two parallel 25-
pin D-Sub connectors for connecting multiple
SP1200s and SP2400s together in a serial fashion.
Any of the four program sources from any SP1200
and SP2400 can be used as the source for any of
the zones in the system by assigning it to the
expansion bus with the internal Bus Assign switches.
This is a balanced bus for the four stereo input
sources. In addition, the paging mic and paging control
signal are also provided on the EXPANSION bus.
MIC/LINE INPUT is provided to connect a local
microphone. This is a 3-pin Phoenix-type connector
where pin 1 is ground, pin 2 is signal high (+), and
pin 3 is signal low (–).
AMBIENT MIC is a 3-pin Phoenix-type connector
used to connect the optional MT-3100 ambient
microphone. This microphone is used to detect the
ambient noise level in the room. The
microprocessor uses this information to adjust the
paging mic level above the ambient noise. The
ambient mic also provides an input for the optional
DSP card when it is installed.
LOCAL/REMOTE is a set of eight DIP switches
used to select the input source for each input. Each
program input has two switches, one to select the
left signal source (odd-numbered switches) and one
to select the right signal source (even-numbered
switches). Move the switches up to select the local
program source, and down to select the remote
(external) program source from the EXPANSION bus.
EQ is a 3-band equalizer with a sweepable
midrange that only affects Inputs 1-4. LOW is a
shelving filter that provides 15 dB of boost and cut
below 80Hz. MID is a peaking filter that provides
15 dB of boost and cut at the selected frequency
between 250Hz and 8kHz. HIGH is a shelving filter
that provides 15 dB of boost and cut above 12kHz.
PRE OUT is an unbalanced RCA jack that
provides a line-level signal from the preamplifier
stage of the SP1200. This provides a method for
inserting an external signal processor into the signal
chain prior to the amplifier stage. The U-shaped
jumper wire should remain installed between the
PRE OUT and AMP IN jacks for normal operation.
AMP ADDRESS is used to assign a unique
address to the amplifier, as well as to enable or
disable features. Switches 1-5 provide 32 separate
addresses, switch 6 determines Master/Slave
status, switch 7 enables Input 4 Priority, and switch
8 enables the optional ambient mic. Any two
amplifiers assigned to the same address can be
controlled by a single remote control when
connected together via the RS485 ports.
AMP IN is an unbalanced RCA jack that accepts
a line-level signal. See PRE OUT above.
ZONE A OUTPUT is a 2-pin Phoenix-type
connector that provides speaker-level signals. The
SP1200 is shipped with the outputs configured for
70-volt operation in U.S. versions, and 100-volt
operation in European versions. Internal jumpers are

Note: This application provides independent source selection for each zone, or common input
source selection for both zones (room combining). Both DX8 Selection Remote Controls are used
to select Presets 1 and 2.
For example, Preset 1 might route the CD Player and the Zone A microphone to Zone A, and the
Cassette Player and the Zone B microphone to Zone B, to be used when the divider is in place
between the two zones. Preset 2 might route both microphones and the audio signal from the
laptop to both Zones A and B, to be used when the divider is removed between the two zones.
Each zone on both SP1200s are assigned the same AMP ADDRESS, so when “OFF” is selected
on one SP1200, the DX8 signal at the Mic/Line Input is routed to the SP1200 outputs. The local
input sources (Tuner and CD 5-Disc Changer) or the Global Background Music via the Expansion
I/O can be routed to the SP1200 outputs by selecting 1, 2, or 4 on the SP1200 front panel.

Applications
A: Typical Mono Application
D: Multiple SP1200s, Multiple Zones:
This diagram depicts a typical setup, using the
SP1200 in a mono application. A Digital Satellite
Service (DSS) is connected to Input 1, which also
serves as the music-on-hold for the telephone
system. A CD player and cassette deck are con-
nected to Inputs 2 and 3 for general purpose music
playback. A jukebox is connected to Input 4, which is
configured for priority playback via AMP ADDRESS
switch #7.
An ambient mic is connected to provide paging
level compensation for varying ambient noise levels
in the room. This amplifier has been configured for
8-ohm operation.
Room Combining—Zones
In this example, a dividing wall can be extended
to divide the room into two. The Mackie Industrial
DX8 is used to route independent source selections
to each zone (Preset 1 on the Remote Controls), or
common input source selections for both zones
(Preset 2 on the Remote Controls).
For example, Preset 1 might route the CD Player
and the Zone A microphone to Zone A, and the
Cassette Player and the Zone B microphone to
Zone B, to be used when the divider is in place
between the two zones. Preset 2 might route both
microphones and the audio signal from the laptop
to both Zones A and B, to be used when the divider
is removed between the two zones.
B: Multiple SP1200s: Multiple Zones
In this example, two SP1200s are used in a
system with two separate zones configured for 70V
operation (default configuration for U.S. versions).
Four program sources are connected to Unit 1. Of
these, only the DSS and Jukebox signals are shared
with Unit 2 by means of the Expansion Bus. Inputs
1 and 4 are assigned to the Expansion Bus via the
internal Bus Assign switches. Both units have sources
connected to Inputs 2 and 3 that are exclusive and
not shared between units. Each unit/zone has a
different AMP ADDRESS assigned, and each
remote control exclusively operates its own zone.
The Paging Mic can be manually operated with
the Paging Mic Control Switch, and the Paging Mic
and ALL CALL control signal is transferred to Unit 2
via the Expansion bus.
Both zones are assigned the same AMP
ADDRESS, so when “OFF” is selected on either
SP1200, the DX8 signal at the Mic/Line Input is
routed to both SP1200 outputs. The local input
sources (Tuner and CD 5-Disc Changer) or the
Global Background Music via the Expansion I/O
can be routed to the SP1200 outputs by selecting
1 (global remote), 2 (tuner), or 4 (CD) on the
SP1200 front panel.
Tips on Installing and Using the
SP1200—Plan Ahead!
The key to any successful installation is
planning your system well in advance. Know which
components are going to be used in the system,
their locations, and how they will interface with
each other. Plan the wire routing and AC power
requirements.
Each ambient mic and local mic operates
independently in its own zones.
C: Multiple SP1200s, Multiple Zones:
Expansion with Local Mic
Here are some steps to follow to help insure a
smooth installation of the SP1200:
This example shows how to share the Local Mic/
Line input with another zone, along with the remote
Expansion Bus signals.
Zone A and Zone B are assigned the same AMP
ADDRESS, with Zone A assigned Master status and
Zone B assigned Slave status via AMP ADDRESS
switch #6. This allows the front panel buttons for
both zones, and all the remote controls, to operate
both zones simultaneously.
When an input is selected, it is heard in both
zones because Zone A is set to LOCAL input
source, and Zone B is set to REMOTE input source
over the Expansion Bus. When OFF is pressed, the
Local Mic connected to Zone A is heard in both
zones because the PRE OUT from Zone A is
connected to the MIC/LINE input on Zone B.
1. How many zones require coverage in the
system? This will determine how many SP1200s
you need in the system.
2. How many program sources are going to be
used? If the number of program sources is four or
less, they can be centralized at one SP1200 and
distributed via the Expansion Bus. If there are more
than four program sources, they must be
distributed among the SP1200s. Determine the
number and location of the program sources that
are going to be used.
Determine which program sources are going to
be used for each zone, and set the LOCAL/REMOTE
and internal BUS ASSIGN switches appropriately.
SP1200 – 10
Download from Www.Somanuals.com. All Manuals Search And Download.
CAUTION: When using multiple SP1200s
that use the expansion bus, these switch
settings must be unique to each unit or
you can damage your SP1200(s). Never assign
more than one program source to the same channel
on the Expansion Bus.
Connections
Connecting the Program Sources
All four Program Inputs use unbalanced RCA
connectors. They accept line-level signals (–10
dBV). Each of the Program Inputs is equipped with
an AGC circuit instead of input trim controls. These
circuits automatically adjust the gain for the best
signal-to-noise ratio according to the strength of the
input signal. It also ensures that the relative volume
level remains the same when switching between
input sources.
If there is a requirement for music-on-hold, use
Input 1 for the continuous music source (i.e.,
satellite feed, prerecorded background music, multi-
disc CD player). Then use the DIRECT OUTPUT
jacks to route the signal to the telephone system.
If there is a jukebox or other device that needs
priority, use Input 4 in Program Priority mode (set
the AMP ADDRESS switch #7 UP to activate).
When a signal appears at Input 4 it overrides the
selected Input source.
Use high-quality, two-conductor shielded cable
to make these connections.
Connecting the Microphones
Using a chart similar to the one below can be
very helpful in organizing the various components
of the system:
If using the XLR input for the paging microphone,
wire it per AES standard where pin 1 is ground
(shield), pin 2 is signal high (+), and pin 3 is signal
low (–). If using the Phoenix-type connector, strip
the wire back about 1/4" inch. Then insert the wire
as far as it will go into the appropriate hole in the
connector, and tighten down the screw with a small
slot-head screwdriver. It is recommended that you
use 20 or 22 gauge wire with the Phoenix-type
connectors, where pin 1 (the left-most pin) is
ground (shield), pin 2 is signal high (+), and pin 3 is
signal low (–).

The MIC/LINE INPUT A is for a local microphone.
This is a Phoenix-type connector, and is wired as
described in the previous paragraph for the paging
microphone.
All microphone inputs are equipped with a pad
switch for use with line-level signals. When connect-
ing a line-level signal to these inputs, make sure the
GAIN +40 dB switches (and the PHANTOM
switches) are in the up (OFF) position.

3. Is there a paging microphone? Is there a
requirement for a local microphone for a guest
speaker? You must decide where the microphones
are going to be located. Avoid placing a microphone
near a speaker, to increase gain before feedback. If
the mics require phantom power, set the PHANTOM
power switches to the down position (ON) for the
Paging Mic and Mic/Line Inputs. Make sure the
GAIN +40 dB switch is set to the down position as
well (+40).
Connecting the Speakers
The speaker output connector is a two-
conductor Phoenix-type, with a position-locking
mechanism. Use 16 or 18 gauge wire for connecting
the amplifier outputs to the speakers. If the amplifier
output is configured for 8-ohm operation, connect
the speakers' output directly to an 8-ohm load. The
amplifier will deliver up to 200 watts. If the amplifier
is configured for either 70V or 100V operation,
connect the speaker output directly to the
distributed system. No output transformer is
required. Make sure that the taps on the speakers
add up to 200 watts or less per amplifier for 70V or
100V systems.
Note: The Paging Mic has priority over the system,
including Input 4.
4. Is there a manual switch for paging? Up to
two switches can be connected to the SP1200
PAGING MIC CONTROL to manually engage the
paging microphone. Otherwise, the paging mic can
be voice-activated. Adjust the VOX control as
described on page 19.

Connecting the Expansion Bus
These are 25-pin D-Sub connectors (DB25F). The
two connectors are wired in parallel, so it doesn’t
matter which one you use as an input or output.
The signals on the EXPANSION IN/OUT are
balanced so they can be transmitted down long
lines. The limiting factor is the capacitance of the
cable, which causes the higher frequencies to roll-
off as the capacitance increases (see chart below).
The chart indicates the lengths of cable at which
the high-frequencies are 1 dB down and 3 dB down,
using cable rated at 20pf/ft and 30pf/ft.

Connecting the Remote Bus
This is a 3-pin Phoenix-type connector
Distance Chart for SP1200 Expansion Bus Cable
specifically for connecting the optional remote
control. Use a high-quality three-conductor shielded
cable to make this connection, such as Belden
8451, 9451, or equivalent. The lower the nominal
capacitance of the wire, the more distance you can
have between the remote control and the SP1200
before suffering transmission losses.
For local interconnection of the Expansion Bus,
the use of standard computer cable with an overall
shield is acceptable, such as Belkin Pro Series 25-
Conductor Straight-Through Cable Assembly (Part
Number F3D111-06) or equivalent. Ensure that the
cable is wired straight-through and terminated to
DB25M connectors on each end.
Strip the wire back about 1/4 inch, insert the
wire as far as it will go into the appropriate hole in
the supplied Phoenix-type connector, and tighten
down the screw with a small slot-head screwdriver.
It is recommended that you use 18 to 24 gauge
wire for the remote control connections, depending
on the distance between the SP1200 and the
remote control.
Note: The use of ribbon cable is permissible for
these connections, only where the total length of
each cable is 12" (30cm) or less.

Program Input Source has four corresponding
switches: Left (+), Left (–), Right (+), and Right (–).
Typically, you would move all four switches either
down (off) or up (on to assign to expansion bus).
Connecting the RS485 Serial Port
This is a 3-pin Phoenix-type connector that
follows standard RS485 protocol. Select either a
data-grade shielded twisted pair cable or a standard
3-conductor microphone cable for this connection.
The RS485 port is wired as follows:
Pin 1 = A (non-inverting I/O)
Note: These DIP switches can be
accessed without removing the cover of
the unit. A flathead screwdriver at least 2"
(50.8 mm) long, and no larger in diameter than 1/8"
(3.175 mm) is required. See illustration below.
Pin 2 = G (Ground)
Pin 3 = B (inverting I/O)
The SPLinker Sound Palette Control PC
application uses the RS485 serial port to connect
between a computer and the SP1200. Connect the
PC RS485 port to the first SP1200, and then inter-
connect up to two SP1200s in the system using
their RS485 connections.
Note: It may be necessary to install an RS485
interface card in the PC, or to use an RS232 to
RS485 converter.
CAUTION: When using multiple SP1200s
that use the expansion bus, these switch
settings must be unique to each unit or
you can damage your SP1200(s). Never assign
more than one program source to the same channel
on the Expansion Bus.
Insert screwdriver through grill hole to adjust DIP switches.
Use a flashlight to aid in viewing the DIP switches.
Two SP1200s can be connected together for
stereo operation (each SP1200 assigned the same
AMP ADDRESS, with one assigned Master, and the
other Slave).

If installing three or more SP1200s in a rack, use a
fan in the rack to move cool air in and warm air out of
the rack's enclosure. It may be necessary to provide
a cool air intake fan at the bottom of the rack, and a
warm air exhaust fan at the top (see Figure below).
If the amplifier should overheat, a thermal switch
is activated that disengages the speaker output,
allowing the heatsink to cool down. The OVERLOAD
indicator on the front panel will also light to show
that a protection circuit has been activated. Once
the amplifier has cooled to a safe operating tem-
perature, the thermal switch resets and reactivates
the speaker output. If this should occur, identify the
cause of the problem and take corrective action,
such as providing better ventilation, installing a fan
in the rack to move more air, making sure the
amplifier is not overloaded with too low of a load
impedance, etc.
AC Power Considerations
Each SP1200 draws an average of 3 amps of AC
line current (@ 120VAC) when fully loaded and
playing music with a relatively high crest factor.
Voltage Conversion
The SP1200 can be configured to operate at
115V AC or 230V AC. See Appendix C for instructions
on how to change the operating voltage configuration.
Thermal Considerations
IMPORTANT: The SP1200 is convection
cooled rather than fan cooled. This design
was chosen to avoid the requirement for
periodic air filter maintenance, and to keep the
insides of the SP1200 clean in dirty environments.
This avoids blowing dirty, smoky air into it. Heat is
drawn away from the amplifiers by the heatsinks
and radiated through the cooling vents in the top
cover. When installing the SP1200, be sure to allow
sufficient air space around the top and rear of the
amplifier to allow adequate cooling for the
heatsinks. If installing in a rack, leave at least one
rack space above and below the SP1200 for a vent,
and at least 6 inches behind the chassis to allow
proper ventilation.

4. Operation
SP1200 Quick Start
• Bus Assign switches are used to assign a
program input source to the balanced expansion
bus. There are four switches for each program input
source: Left (+), Left (–), Right (+), and Right (–).
This isn’t a substitute for reading the entire
instruction manual, which is the only way to fully
understand how the SP1200 works. However, the
Quick Start provides a quick overview so you can
get the SP1200 set up and working right away.
Make sure the power switch is off while
setting up and making connections to the
SP1200.
CAUTION: When using multiple SP1200s
that use the expansion bus, these switch
settings must be unique to each unit or
you can damage your SP1200(s). Never assign
more than one program source to the same channel
on the Expansion Bus.
External Switch Settings
• The Paging Mic and the Local Mic have +24 VDC
PHANTOM power switches. Move the switches
down to activate the phantom power if you are
using condenser microphones.
• EQ Bypass allows you to bypass the 3-band EQ,
which is in the Input 1-4 signal path. EQ engaged is
the default setting.
• The amplifier can be configured for 8-ohm, 70V
(default for U.S. versions), or 100V (default for
European versions) operation via eight jumpers on
the amplifier board.
• The Paging Mic and Local Mic also have GAIN
+40 dB switches. Leave the switches in the down
position when microphones are connected to these
inputs.
Program Inputs
• If you plan on connecting two or more SP1200s
together in a system with the EXPANSION IN/OUT
bus, use the LOCAL/REMOTE switches. They select
either the local Program Input source (switches up)
or a remote program source from the EXPANSION
IN/OUT bus (switches down). The odd-numbered
switches (1, 3, 5, 7) select the left inputs, and the
even-numbered switches (2, 4, 6, 8) select the right
inputs.
Connect any stereo line-level signal source to
the Program Inputs 1-4. If you have a music-on-hold
requirement, connect a continuous music source to
INPUT 1. The DIRECT OUTPUT jacks next to INPUT 1
can feed the signal connected to INPUT 1 to the
telephone system.
If you have a need for a priority Program Input
(e.g., a jukebox), connect it to INPUT 4. Move the
AMP ADDRESS switch #7 UP to enable INPUT 4
priority.
Set the 3-band EQ controls to the “U” position
for now (1K for the FREQ control). These can be
• To operate two SP1200s with one remote
control, assign the same AMP ADDRESS setting to
both amplifiers (DIP switches 1-5). Set the AMP
ADDRESS DIP switch #6 to the Master position on
one amplifier and to the Slave position on the other
amplifier. The front panel and remote control panels
operate both amplifiers when they are assigned to
the same AMP ADDRESS. For example, if you
select Program Input 1 with one unit's Input Select
control, Program Input 1 is also selected for the
other unit.

EXPANSION IN/OUT
PAGING MIC CONTROL
If you are connecting two or more SP1200s in a
system, use the EXPANSION IN/OUT connections
to distribute the Program Input sources assigned to
the Expansion Bus between SP1200s. The two 25-
pin D-Sub connectors are in parallel (use one to
connect to the previous SP1200 and one to connect
to the next SP1200 in the chain).
The PAGING MIC CONTROL connector is
provided to connect a manual paging switch.
Connect a normally-open switch between GND and
ZONE A (to page in Zone A only), or GND and ALL
CALL (to page over the entire system--if using
multiple units). The voice-activated (VOX) control for
the Paging Mic still operates in Zone A when the
switch is off.
Remote
Local MIC/LINE Input
You can connect one or more optional remote
controls (up to 10) to the SP1200 to provide wall-
mounted input select, program signal volume control,
and local mic volume control.
Connect a microphone to MIC/LINE INPUT A
,
using the supplied Phoenix-type connector, to use for
a meeting room or other local speaking
requirements. Set the PHANTOM and GAIN +40 dB
switches to their appropriate positions.
Select the OFF button on the front panel. This
disengages the selected Program Source and
engages the MIC/LINE INPUT. Adjust the MASTER
VOLUME up/down buttons so the meter level is at
the “0” mark.
Note: The MASTER VOLUME setting for the
MIC/LINE INPUT is independent of the MASTER
VOLUME setting for INPUTS 1-4. The MASTER
VOLUME setting for INPUTS 1-4 is stored in
memory when the MIC/LINE INPUT is selected (the
OFF button is engaged). When an INPUT 1-4 is
selected, the MASTER VOLUME setting for the
MIC/LINE INPUT is stored in memory.
RS485
A PC can be connected to the RS485 port to
provide computer control using the SPLinker Sound
Palette Control software application. If the PC
doesn't have an RS485 serial port, you can either
install an RS485 interface card, or use an RS232
serial port with an RS232-to-RS485 converter.
Two SP1200s can be controlled with one wired
remote control by connecting the RS485 ports
between the two SP1200s. Each amplifier must
have the same AMP ADDRESS with one assigned
as Master and the other as Slave. Use the supplied
Phoenix-type connectors to make these
connections.
Set the GAIN control so the meter indication is
near the “0” mark when speaking at an average
level into the microphone.
Note: Move the AMP ADDRESS switch #6
DOWN for Master and UP for Slave.
Set the 2-band EQ (LOW and HIGH) to the “
position. These can be adjusted later, if necessary.
U“
PRE OUT/AMP IN
These connections can be used to insert a signal
processor (i.e., graphic equalizer, compressor, etc.)
into the signal chain, or to feed the signal to additional
power amplifiers. If no external processor or external
amplifier is to be used, leave the U-shaped jumper in
place between the PRE OUT and AMP IN connectors.
AMBIENT MIC Input
This is an optional connection, but can greatly
enhance the performance of the Paging Mic.
Connect the optional MT-3100 mic to the AMBIENT
MIC input. This provides an “ear” for the
microprocessor to adjust the Paging Mic gain to
compensate for the ambient noise level in the
room. Use the supplied Phoenix-type connector to
make these connections.
Outputs
Use the supplied two-conductor Phoenix-type
connector with appropriate speaker wiring to
connect to the speaker or distributed speaker
system.
Note: Move the AMP ADDRESS switch #8 UP to
enable the ambient mic. See page 19 for more
information on "Using the Ambient Mic."

Using Inputs 1-4
Bus Assign
Connect the program sources to Inputs 1-4.
These could include a CD player, tape deck, tuner,
satellite feed, TV audio, jukebox, or an audio feed
from a live band. All four program inputs use
unbalanced RCA connectors and accept stereo line-
level signals.
Note: The Input Select buttons are labeled 1
through 4 on the front panel. The spaces below the
buttons are sized to accept 1/4" labels from the
Brother P-Touch Electronic Labeling System.
Professional-looking labels can be made to clearly
identify the program source connected to each
There are no individual volume controls for
Inputs 1-4. The SP1200 automatically adjusts the
volume for each input using an AGC circuit
(Automatic Gain Control). This provides the best
signal-to-noise ratio and insures that the volume
remains the same when you switch from one
source to another.
Only one Input source can be selected at a time.
When switching from one source to another, the
previous source fades out while the new source
fades in (digital crossfade), rather than abruptly
switching between the two.
These internal switches are used if you have two
or more SP1200s connected together in a system
using the EXPANSION IN/OUT connectors. Each of
the four program inputs can be individually assigned
to the EXPANSION balanced bus. There are four
switches associated with each Program Input source
(see the Bus Assign Switch chart on page 13).
CAUTION: When using multiple SP1200s
that use the expansion bus, these switch
settings must be unique to each unit or
you can damage your SP1200(s). Never assign
more than one program source to the same channel
on the Expansion Bus.
EXPANSION IN/OUT
These two 25-pin D-Sub connectors are used to
connect two or more SP1200s together so they can
share program sources. This is a true balanced bus
and transmits the left and right signal from each of
the four inputs over balanced lines. Refer to the
“Connections” section on page 11 for information
on wiring these connectors.
These connections allow a common program
source to be available to all the SP1200s in a
system. For example, prerecorded music that is
used for music-on-hold can also serve as background
music for an entire office building by setting the
internal bus assign switches for Input 1 to the up
position on the first SP1200. The music is then
available to Input 1 on all the SP1200s connected
via the EXPANSION IN/OUT connectors when their
LOCAL/REMOTE switches are set to the REMOTE
position (down).
Note: Switching the LOCAL/REMOTE switch to
REMOTE doesn't disconnect the local input. If a
different program source is connected locally to
Input 1 on one of the SP1200s in the above
example, both the common program source (the
remote prerecorded music) and the local program
source will be combined on Input 1 and can be
played simultaneously. Typically, a local program
source would not be connected to an Input which
has REMOTE selected as the source.
Input 1 and the DIRECT OUTPUT
Input 1 provides a direct line-level output that
can be used for music-on-hold or other external
applications. Connect a continuous music source
(i.e., satellite feed, prerecorded background music,
multi-disc CD player) to Input 1 and connect the
DIRECT OUTPUT jacks to the external destination.
Input 4 Priority
Normally, the four program inputs are non-
priority inputs. However, if there is a jukebox or
other priority program source in the system,
Program Priority can be activated on Input 4 by
setting AMP ADDRESS switch #7 UP. When a
signal appears at Input 4, it overrides the other
three inputs. When the signal stops, the SP1200
switches back to the previously selected input
source, fading it in smoothly.
Local or Remote
Using the 3-Band EQ
These switches are used to select the input
source for each of the four Program Inputs. Leave
the switches up to select the local input source
connected to the PROGRAM INPUT connector.
Move the switches down to select the remote
signal coming from the EXPANSION IN connector.
Each Program Input has two switches, one for the
left input and one for the right input.
This equalizer is applied to the selected program
source from Inputs 1-4, whether it is a local source
or remote source (via the EXPANSION IN/OUT bus).
This equalizer does not affect the paging mic or
the local MIC/LINE INPUTS, which each have their
own 2-band EQ controls.

Using the Paging Mic
The paging mic is used to make announcements
over the system. If the paging mic is a condenser
mic or other type of mic that requires phantom
power, move the PHANTOM switches to the down
position. Otherwise, leave them switched up.
The paging mic can be voice-activated and is
routed to all channels or zones. However, you have
the option of activating it manually with an external
switch. If you choose to use a switch for the paging
mic, you have the additional option of assigning the
paging mic to either Zone A or to all zones (if multiple
SP1200s are used).
indicates a level at the “0” mark. With all music
sources off, speak into the paging mic with a
normal voice. Adjust the PAGING MIC GAIN control
with a non-conductive alignment tool so that the
meter indication is near the “0” mark. This provides
the best signal-to-noise ratio for the mic, and
insures that the signal from the paging mic is strong
enough to trigger the VOX circuit.
• For Zone A only, connect a (normally-open)
switch between the ZONE A and GROUND pins on
the PAGING MIC CONTROL connector.
Setting the VOX Threshold
This control determines how strong the signal
from the paging mic must be to trigger the VOX
circuit, which ducks the program source when an
announcement is made. Ideally, the threshold
should be set so it is sensitive enough to trigger the
VOX circuit as soon as you begin speaking, but not
so sensitive as to be triggered by ambient sounds
around the microphone. Set the PAGING MIC VOX
control to the center position with a non-conductive
alignment tool to start. Turn the control counter-
clockwise to lower the threshold (increase the
sensitivity) if the beginning of announcements are
getting clipped off. Turn the control clockwise to
increase the threshold (decrease the sensitivity)
should you experience false triggering due to
ambient noise around the microphone.
• For all zones in a system interconnected via the
EXPANSION bus, connect a switch between the
ALL CALL and GROUND pins on the PAGING MIC
CONTROL connector.
• For maximum flexibility, connect two switches
to the PAGING MIC CONTROL connector and have
both selections available.
The paging mic can be configured to automatically
turn down (duck, or attenuate) the music that is
playing over the system so the announcement can
be heard when using the VOX circuit. When an
announcement is over, the music gradually returns
to its original volume.
The music ducks fairly rapidly, attenuating the
music 20 dB within 300 ms (milliseconds) of
detecting a signal on the paging mic. When the
signal on the paging mic stops, there is a 1500 ms
(1.5 second) timeout period to make sure the
announcement is over, and then the music ramps
up to its original volume over the next 2.5 seconds.
Note 1: When manually activating the paging mic,
there is no timeout period after the announcement
ends. The moment you let go of the switch, the
music begins to ramp up to its original volume.
Note 2: When the manual switch is off, the
voice-activated (VOX) control for the paging mic is
still operational. Ensure that the PAGING MIC VOX
threshold is set accordingly to prevent false
triggering of the paging mic input when using
PAGING MIC CONTROL switching. Alternatively,
turn the PAGING MIC VOX control all the way up
(fully clockwise) to defeat the VOX circuit. Note that
each zone has its own PAGING MIC VOX control.
Using the EQ
The paging mic has a 2-band equalizer for
adjusting the lows or highs on the microphone
signal. When the controls are set to “U” (unity), the
EQ has no effect on the signal.
Using the Ambient Mic
The ambient mic is an optional accessory (MT-
3100) that is available for the SP1200, which is used
to sense the ambient noise level in the room. Set
the AMP ADDRESS switch #8 up to enable the
ambient mic, otherwise leave the switch down.
The ambient mic provides an “ear” for the micro-
processor to gauge the ambient noise in the room and
adjust the gain of the paging mic accordingly. When
the background noise is relatively quiet, the paging
mic gain is at its lowest level. If the background
noise is relatively loud, the paging mic gain is at its
highest level. If the background noise is some-
where in between, the paging mic gain is midway
between its lowest and highest preset levels.
Setting the GAIN
When a microphone is connected directly to the
paging mic input, the GAIN +40 dB switch should be
set in the down position (for a mic-level signal). When

8. Use the front panel Up/Down buttons to set the lower
level of the paging mic (how loud it is with very quiet
background noise). It should be loud enough to be
heard clearly throughout the coverage area.
Ambient Mic Calibration and Placement
1. Connect the MT-3100 (or other microphone) to the
AMBIENT MIC connector on the rear panel. Make sure
the ambient mic switch is on (AMP ADDRESS switch
#8 up). Locate the ambient mic in an appropriate
position to pick up the ambient noise in the room. It
can be mounted on the ceiling or on a wall. Avoid
placing the ambient mic close to the speaker over
which the announcement is being made. Keep the
ambient mic away from a constant noise source, such
as a refrigerator or other mechanical device that emits
a continuous noise. The best placement is where the
mic can pick up an average representation of the
ambient noise level in the room.
9. Press the “OFF” button and the level is stored. The
third LED starts flashing faster.
10.Use the front panel Up/Down buttons to set the upper
level of the paging mic (how loud it is with very loud
background noise). As a general rule, set this level as
high as it will go before feedback (at the "0" mark if
steps 3-4 above were followed).
11.Press the Input 3 button when finished to store the
level and return to normal operation.
Note: Each zone or channel must be calibrated
individually.
12.Verify that the paging microphone’s volume is sufficient
to be heard over the background noise in the room.
2. Turn off the SP1200, then turn it back on again while
pressing and holding the Input 2 button. This causes
the ambient mic preamp level to appear on the meter.
Note: For best results, with the background noise
level at a minimum, the paging mic volume should be
approximately the same as the music volume.
3. Establish the highest noise level that you would
expect to have in the room using a pink or white noise
source, or a music source. Input 1 is operational in this
mode to use as a music source, if desired.
13.If the paging microphone is not loud enough to be
heard over the background noise, verify that the
ambient mic is properly placed to pick up an accurate
representation of the background noise. If it is, it may
be necessary to readjust the lower and upper levels
for the paging mic gain (steps 6-11).
4. The ambient mic preamp gain trim is located just
above the ambient mic connector on the rear panel,
through the unmarked hole. Adjust it with a non-
conductive alignment tool until all the green LEDs on
the meter are lit. Insure that no yellow or red LEDs are
lit, which runs the risk of clipping the ambient mic
preamp or ADC.
Using the Local MIC/LINE INPUT
The MIC/LINE INPUT A is provided for the zone
to connect a microphone for a speaker in a
conference room, or similar sound reinforcement
applications. If the local mic is a condenser mic,
move the PHANTOM switches to the down position.
5. Press the “OFF” button when finished to return to
normal operation.

Using the PRE OUT/AMP IN
Connections
The PRE OUT and AMP IN connectors are
provided to give you more flexibility in your system
design. The SP1200 is shipped with U-shaped
jumpers installed between the PRE OUT and AMP
IN jacks. This routes the signal from the output of
the preamplifier stage to the input of the amplifier
stage.
This also provides a point in the signal chain to
insert an external signal processor. Simply connect
the line-level signal from the PRE OUT jack to the

Another option that is available is to connect
another amplifier into the system. Simply use a
Y-cord at the PRE OUT jack to split the signal
between the AMP IN jack and the input jack on an
external amplifier.
Connecting One or More Remote Controls
Each Remote Control affects only the zone to
which it is connected. Up to ten remote controls
may be connected to each zone simultaneously.
This allows controls to be conveniently placed.
Each control will interact with the SP1200, and all
controls will reflect the current source and level
settings. Note that the remote control indicates the
gain setting and not the actual signal level in real
time. In addition, the SP1200 provides a method for
controlling two independent zones using a single
Remote Control by assigning them to the same
AMP ADDRESS (see next section).
The maximum distance between the remotes
and the SP1200 varies, depending on the type of
cable selected and the number of remote controls
used. Typically, a lower wire gauge and cable
capacitance allow longer distances. See the instruc-
tions with the remote control for more information.
Zone A Output
The amplifier output on the SP1200 can be used
with an 8-ohm impedance load, or to drive a 70V or
100V distributed system directly (also called
constant-voltage systems).
Direct Speaker Connection
If the SP1200 is not being used in a distributed
speaker system, you can reconfigure the amplifier
to drive an 8-ohm load. Each amplifier can provide
up to 200 watts into an 8-ohm load. See the
"Internal Settings" section on page 13 for
instructions on how to reconfigure the amplifiers.
Distributed Speaker System
When using the SP1200 in a 70V or 100V
system, connect the speaker output directly to the
distributed system. The SP1200 can directly drive a
distributed system's speaker line without the need
for an output transformer. The SP1200 can supply
up to 200 watts into a 70V or 100V distributed
system. Make sure the taps on the speakers in the
system do not exceed a total of 200 watts.
Using the RS485 Connection
The amplifier is equipped with an RS485
connection. When two SP1200s are linked via the
RS485 connection and assigned to the same zone
(AMP ADDRESS switches 1-5), the Input Selection
and MASTER VOLUME buttons on both amplifiers
track each other. One unit must have AMP

Using a 3rd Party Control System
The RS485 connection can also be used to
interface with common third-party control systems.
Contact the third-party provider or Mackie Industrial
Technical Support to determine if your control
system is compatible with the SP1200.
ADDRESS switch #6 in the Master position (up),
and the other unit in the Slave position (down).
In this way, you can have one Remote control
operate both amplifiers that are assigned to the
same zone.
Note: The microprocessor polls the AMP
ADDRESS switch when it initializes at power-up. If a
change is made to the AMP ADDRESS switch, turn
the SP1200 off for five seconds, then turn it back
on again for the new settings to take effect.
Upgrading the Software
From time to time, Mackie Industrial will release
upgrades for the internal operating software in the
SP1200. This can be downloaded from our website
computer. Use the serial port on the computer to
connect to internal connector on the SP1200's CPU
board to transfer the data to the on-board flash
memory. Instructions will be provided when
upgrades are available.
Using the SPLinker Sound Palette
Controller
The RS485 connection can also be used to
connect the SP1200 to a computer loaded with the
SPLinker software application. The PC-compatible
computer must have an RS485 port to properly
connect to the SP1200. It may be necessary to
install an RS485 interface card, or use an RS232
port with an RS232-to-RS485 converter.
The SPLinker is a PC-based graphical interface to
provide real-time monitoring and control (for up to
32 zones when used with SP2400s). It provides
individual program source selection and volume
control for each zone. Select boxes are located at
the bottom of each zone for selecting multiple
zones. All selected zones can then be modified at
the same time in the Multiple settings box located
on the right-hand side of the screen.
