Features
Thank you for purchasing an Integra MZA-4.7 Multi-Zone Amplifier.
Please read this manual thoroughly before making connections and plugging in the unit.
Following the instructions in this manual will enable you to obtain optimum performance and listening
enjoyment from your new Multi-Zone Amplifier.
Please retain this manual for future reference.
A MZA-4.7 may receive IR directly from the front panel
receiver or via the two “Controller Interface” connec-
tions.
There are zone specific IR commands and also a set of
global IR commands.
The commands are: ON, OFF, Standby (toggling), Mute,
Amp Volume Up, Amp Volume Down, Pre Volume Up,
Pre Volume Down, Source Selects, On with Source Spe-
cific commands.
The Global commands also include PRESET1 - PRE-
SET 6, Alarm Enable, Alarm OFF, and 5 minute Sleep.
Multi-Zone, Multi-Source, Video Switching
The MZA-4.7 has four separate preamplifiers and ampli-
fiers, providing 4 zones of independent yet integrated
control.
There are seven stereo sources (S1 - S7) and an eighth
mono source (S8) typically used for paging applications.
Each zone has an eight-source composite video switcher,
so monitor screen’s in four different rooms may display
any of the eight sources (S1 - S8).
Preamplifiers and Outputs
Each zone has bass, treble, balance and loudness control.
These are accessed either from the front panel or IMC
(Integra Music Center) program.
The preamplifier output volume may be independent of
the amplifier volume, or made to track the amplifier with
an adjustable offset ( 20dB). The tracking feature is
ideal for passive subwoofer control, while the indepen-
dent volume feature is useful for limited control in
closecoupled rooms.
Real Time Clock
The MZA-4.7 is equipped with a real time clock.
The amplifier may be set up to function as an alarm
clock, so that at 6.30am in the morning 5 days a week,
the master bedroom zone could be made to turn on,
select tuner, and go to a specific volume. Multiple
Alarms are feasible (max of 6) However the Alarm
Enable & OFF commands act upon all programmed
Alarms.
A useful protection feature is “Maximum Volume limit-
ing.” This limits the maximum volume of either the
amplifier or preamplifier.
The clock continues to operate typically > 48 hours with-
out power – more than enough to keep the time current
during lengthy power outages.
Amplifier Power, Protection, and Clipping
Indicators
IR Emitter Ports
There are 4 Buffered IR emitter Ports.
50 Watts RMS per channel into 8 ohms, capable of driv-
ing into 6 ohms.
The amplifiers are protected against short-term output
shorts.
The front panel zone indicators will flash red when the
zone amplifiers are overdriven into clipping.
Two IR ports have routing, and are linked to their respec-
tive “Controller Interface” ports. These ports control
zone specific source components. Two IR ports are the
sum of both IR sources; these control theAll zone source
components.
Presets and Paging
Thermal Control
There are six amplifier presets and a page preset.
Presets 1 - 6 are momentary and cause the amplifier to go
to a predetermined setup, i.e. standby, volume & source
selection.
There are three progressive levels of thermal control:
• An internal fan is turned on to aid cooling.
• The amplifier volume is reduced 20dB.
The presets may also be programmed with event sched-
uling, and are used by the alarm clock.
• The amplifiers are shutdown until the temperature
reduces below the first level.
The “Page Preset” mode is for paging applications and is
invoked by a contact closure between the “0V” and the
“PG” terminals. When the contact closure is released the
amplifier zones return to their previous states.
Care should be taken to ensure adequate ventilation – see
“Important Safety Instructions” on page 2.
USB, RS232 and IR Control
The MZA-4.7 may be controlled and monitored via
either the front Panel USB or rear panel RS232 serial
interface.
In multi amplifier installations where the amplifiers are
interconnected using an expansion bus cable, only one
USB or RS232 connection is required to control the
stack of amplifiers.
Zone Linking
A zone may be programmed to link one other zone. Zone
linking ties the source selection together. It may also tie
the volume, and standby.
This is useful for closely coupled audio areas where it is

Features—Continued
advantageous to have different volume control but the
same source, or the same volume with separate standby
control. Zone linking is setup either via the front panel
user interface or by the IMC program.
Restoring Defaults clears all memory and resets the zone
allocations to zones 1 - 4.
Setup Lockout
Locks access to the System Setup and More menus
where installation critical adjustments can be made.
Password = 1396
32 Zones
There are 32 zones of possible control.
On a MZA-4.7 each zone must be different, however in
a multiple amplifier stack same zone amplifiers are pos-
sible – they simply mimic every parameter.
Firmware Upgradable
May be updated with the latest operational firmware,
using the USB Uploader program.
Provides a degree of future proofing, and flexibility.
Expansion Bus
Data, IR, Amp-On & Audio sources are interconnected
via the expansion bus.
The expansion bus feature vastly simplifies the installa-
tion cabling of an amplifier stack.
One amplifier is connected to another using a 34-way
ribbon cable. Connections are made from the output of
the first amplifier to the input of the second etc.
All audio sources must be connected to the first ampli-
fier.
Note: Video signals are not passed through the expan-
sion bus.
Door Bell
Looped 1.5 second mono sounds can be generated as
part of a page preset.
Suitable “wav” files are uploaded to the unit using the
IMC program. IMC truncates the “wav” files to a suit-
able size.
12VDC 1A Power
Two 12VDC jacks are available for powering external
accessories – internally fused at 1A (Self-resetting).
Amplifier ON Status – “Amp-On”
Each zone has front panel ON status indication, and
12VDC OUT on the rear panel connector: (1, 2, 3, 4 &
#). The # “AMP ON” output is a logic “And” output, i.e.
if any zone is ON then the output will be 12V. This is
useful for driving a relay that connects AC power to
source equipment. The “AMP ON” output’s are pro-
tected against shorts. The “AMP ON” outputs default to
tracking the preamplifier ON status, but may optionally
be set to track the amplifier ON status using the IMC
program.
Power Failure Restoration
After an AC power outage the MZA-4.7 restores its set-
tings to the pre-interrupted state.
All internal settings are stored in non-volatile memory,
except the clock that runs for at least 48 hours on stored
power.
Restore Defaults
The MZA-4.7 may be set to the default settings.

Typical System Configuration—Continued
Fig 1 depicts a typical configuration, where the
MZA-4.7 is providing audio into four listening zones.
Each zone consists of a room with a pair of speakers, and
a suitable controller. Additionally a zone may require
TV’s or screens. In Fig 1 three such screens are shown in
the Lounge, Gym, and Bedroom. Each zone may be lis-
tening/watching any of the connected sources: Satellite
Receiver, DVD, Video, Digital Music Server, CD
Changer, or Tuner.
All four zones may even select the same source, in such
circumstances there is a possibility that all four zones
may be trying to control that source – this is not always
desirable – so a system should be well planned and
where appropriate additional source equipment
installed.
■ Speakers
Speakers in each zone are connected to the MZA-4.7 by
“Home-Run” speaker cables.
■ Controllers
Each zone has specific control requirements.
Each zone has a maximum loading of 6 ohms.
Fig 1 depicts a powered subwoofer in the study. The
subwoofer is driven by the zone 2 preamplifier, and is set
to track the zone 2 amplifier volume. The subwoofer vol-
ume or offset can be adjusted for correct tonal balance.
Fig 1 additionally depicts a pair of speakers in the bed-
room. These are the associated bedroom ensuite speak-
ers and are driven by a low powered slave amplifier. The
zone 4 preamplifier has been set to “Independent” mode
and connects to the low powered slave amplifier.
Independent mode is where the preamplifier volume
may be different from the amplifier volume (within a
range of 68), it also has independent Standby and Mut-
ing.
• Zone 1 - The Lounge
The ideal control in the lounge environment is from
the sofa or lounge suite.
• Zone 2 - The Study
This is a listening environment where remote con-
trols are not welcome on the busy desk. The best
solution is a wall-mounted keypad. An Integra key-
pad displays amplifier power and source selection
status. The keypad learns the source equipment IR
commands, and relays these to the equipment via the
MZA-4.7.
• Zone 3 - The Gym
■ Video Outputs
An Integra keypad are used to provide additional
access to the CD changer, and SAT receiver. In addi-
tion the Keypads IR receiver is enabled so that
changes can be made using a remote while working
out.
The composite video outputs are suitable for driving
ONE composite video display device. To avoid signal
degradation, home runs of appropriate video cable
should be less than 100 meters.
• Zone 4 - The Bedroom
An Integra keypad is situated by the bedrooms
adjoining ensuite and provides control in that envi-
ronment. The bedroom control is via the keypad’s IR
receiver and a learning remote control.
Source control IR emitters are plugged into the IR out
ports.
There are two IR ports which combine both the control-
ler inputs (IR1 + IR2). These outputs control sources
required in all zones i.e. DVD,VCR, CD and DMS. Each
controller interface has an associated IR Out port that
routes IR only to that output. In Fig 1 the SAT emitter is
plugged into IR out port IR1, which means the zone 1, 3
and 4 controllers may control the SAT source. The Tuner
emitter is plugged into IR Out port IR2, so only the zone
2 controller may control the Tuner.
■ Source Components
The MZA-4.7 has RCA audio inputs for connecting
seven stereo source components and one mono source.
The Fig 1 configuration has only six of the possible eight
sources populated.
Each zone may select from any of the connected sources.
Someone in the lounge may be listening and viewing the
DVD source, while another in the study may be listening
to music from the Digital Music server.

IR routing – discussed in “Typical System Configuration” on page 9 – is used to address specific centrally located source
components.
When several same brand and model source components are required in an installation, steps must be taken to isolate
the radiated IR from interfering with their discrete operation. This may be achieved either by installing them in different
cupboards or by using black IR blocking foam tape over the IR emitters. The IR blocking foam tape is the preferred
solution, since cupboard doors are often left open.
Fig 3 shows a typical installation where several SAT receivers and tuners are required.
The dashed lines enclosing the source components represent IR isolation.

Zone linking is a useful feature for simplifying control in closely coupled rooms, where the rooms require different
volume levels and On/Off status, yet the same audio source.
If for instance the Lounge and Study zones in the “Typical System Configuration” on page 9 were always used together
on the same source, then zone linking could be used to simplify the control of the two otherwise separate zones. Zone
2 is simply linked to zone 1 either via the front panel user interface or IMC program (see page 22). Once linked both
zones will always select the same source whether controlled by the lounge remote control, or study keypad.
It is possible to only link a pair of zones together, i.e. zone 1 linked to zone 2.
On the same MZA-4.7 it would be possible to also link zone 3 to zone 4.
Options are also provided for Linking volume and/or standby via IMC.

Any MZA-4.7 parameter is controllable using the serial RS232 interface. The RS232 protocol is outlined in the follow-
ing section, and encompasses both the amplifier and connected keypads. The interface is bidirectional, allowing the
amplifier and network to be monitored.
The interconnecting cable must be straight: 9 pin ‘D’ connectors.
Fig 6 shows a typical touch panel controller providing the user interface to an MZA-4.7. The controller has its own
operating system that is programmed to handle the RS232 protocol. An automation system is not restricted to touch
panels, it may be an extension of a home lighting, security, building management, or other specialized home automation
system.
The “Page Preset” is a special preset that is invoked whenever there is a contact closure across the “PG” and 0V termi-
nals. Each zone on the MZA-4.7 may be set to a specific input (utility) and at specific volumes (depends on room and
application). When the contact closure is opened the MZA-4.7 returns to its previous states. The “Page Preset” is useful
for telephone paging, door and gate phone paging, or doorbell applications.
Note: The S8 input is summed with the internal doorbell generator.

Notes:
■ Commands are used as notifications. If an amplifier is switched ON, it will notify the other devices on the control
bus by sending the Standby command (01). Any amplifiers with the same zone will take the notification as a
command and also switch ON.
■ When a command is sent to an amplifier it will first be transmitted on the control bus and then returned to the PC
(Home automation system). If an error occurs an error will be returned instead of the original command. The PC
(Home automation system) needs to ignore its command when it is returned.

RS232 Protocol—Continued
■ A Standby ON command implies that the amplifier is not muted, if the amplifier was previously OFF, a mute
command must follow the Standby command if it is muted.
■ Not all Command and Data commands are covered in this document.
■ The expected reply for the “Send all Parameters” command (09) is >144 bytes. All command fields listed in this
document are contained in the reply. The reply also contains advanced commands not listed in this document. The
home automation or PC’s buffer should be large enough to receive and process the 144-byte reply.
■ If two pairs of zones are linked on an MZA-4.7, i.e. zones 1 & 2 and zones 3 & 4, and a “Link Zone” command is
sent that links zones 2 & 3, then the MZA-4.7 has the following implications:
•
•
•
Zone 2 links to Zone 3
Since zone 2 is no longer linked to zone 1, zone 1 shall no longer be linked to zone 2.
Since Zone 3 is no longer linked to zone 4, zone 4 shall no longer be linked to zone 3.
Example strings:
010A01: Standby ON command for zone 10 amplifier
012A01: Standby ON command for zone 10 preamplifier
060002: +2dB Treble setting on zone 0
03IF02: S7 source selection on zone 31 amplifier

Keypad Key Codes
An Integra Keypad may be directed to emit its learnt IR commands via RS232 control.
This is achieved by sending a ‘Cause key press on Keypad’ command “0B” followed by the zone, and the Keypad key
code (data).
The Keypad key code is encoded with IR string repeats. (See table below)
To terminate a continuously repeating ‘Key press’, command a “FF” keypad key code must be sent.

Programming Using IMC (Integra Music Center)
Overview
IMC is an amplifier setup program.
Full control and tracking of any MZA-4.7 zone is provided.
The program runs on PC’s running Win 2000 - Win XP operating systems, and communicates via either RS232 or USB.
When a MZA-4.7 is first attached to a PC running IMC the clock is automatically set to the PC’s current time and date.
A Keypad controller connected to the amplifier may also be controlled by IMC.
Main Window
IMC’s main window provides most of the user functionality required for real-time access and control of any Integra
MZA-4.7 amplifier zone.
The file menu contains the “New Window,” “Keypad Window,” “ViewAmplifier Log,” “Import Keypad File” and “Exit”
commands.
• New Window: Opens another instance of IMC’s main window. This is useful for displaying and controlling multiple
zones simultaneously.
• Keypad Window: A keypad window is displayed, and a user can cause the selected keypad on the network to emit
its stored IR strings.
• View Amplifier Log: Displays all historical over temperature events and the date and time they occurred.
• Upload Sound: Direct IMC to the file location of suitable “wav” files. Click Open to upload the file to the amplifier.
• Exit: Shuts down IMC.
The option menu contains the port assignments. The program lists the ports on the PC/laptop.
Select either USB or a suitable COM port for RS232.

Placing the cursor over the zone tab’s room description displays information about the amplifier’s device ID/serial
number.
■ Zoned Functions
• Standby
On, Off control of the amplifier or preamplifier is achieved by a left click over the standby buttons. The blue LED
and the button shading indicate “On” status.
A name edit window is opened by a right click above the standby Button, enter the new text and click OK to save
and exit.
The room name is transferred to the amplifier.
• Mute
A left mouse click above the mute button mutes the amplifier or preamplifier, a further life click un-mutes it.
• Source Selects
One of eight sources (S1 - S8) may be selected – the button shading indicates the selection. A source’s name may be
changed with a right click over the source select button: A name edit window appears and new text entered.
The short label (limited to 3 characters) appears on the amplifiers front panel, while the Label is displayed in IMC.

• Volume Levels
The volume sliders may be changed either by left clicks above or below the displayed level, or by dragging the level
down using a left click and hold.
Note: If the amplifier is in “Tracking” mode then changing one volume changes the other.
• Maximum Volume Limit
The maximum volume limit is set firstly by identifying the slider with a left mouse click, then on the keyboard hold
down the “Shift” key and adjust the level using the “Up” and “Down” keys. The limit is indicated above the slider
level by a black bar as shown above in the Kitchen’s volume slider.
• Preamplifier Tracking / Independent Mode
The chain link button between the volume sliders is used to toggle the preamplifier volume tracking mode. When
the chain symbol is unbroken the preamplifier volume tracks the amplifier volume. An offset between the preampli-
fier and amplifier volume may be made by identifying the volume bar to be changed with a left click, then make the
change on the keyboard by holding down the “Ctrl” key and adjust the level using the “Up” or “Down” keys.
When the chain link button is broken, the preamplifier is in “Independent” mode.
While in independent mode the preamplifier volume may be adjusted independently from the amplifier volume
with one restriction: the maximum difference between the preamplifier and amplifier volume level is < 68.
• All Off
Left mouse clicks while over the “All OFF” button turns OFF all MZA-4.7 zones.
• Setup
Opens the Setup Window giving access to the occasionally used functions.
• Preset 1 - 6
Momentary Presets. These are used for creating scenes and alarm clock events.
• Preset Setup
Opens the Preset Setup Window where the alarm clock and presets are programmed.

Programming Using IMC (Integra Music Center)—Continued
Setup Window
The window provides the means to control the occasionally used functions like bass, treble, amplifier and preamplifier
balance and loudness. These are all adjusted using a left mouse click while above the button or slider.
Note:
The preamplifier and amplifier share the same bass and treble control.
Loudness is defeated when the preamplifier is set to “Independent Mode”.
Any one zone may be linked to one other zone by left clicking the “Link Zone” down arrow, and making the selection
from the zone list. Linked zones have the same source selection. Volume and standby may also be linked using the “Link
Volume” and “Link Standby” Tabs. If both volume and standby are selected then the two zones are fully linked and
completely mimic each other.
The “Ampon” outputs on the MZA-4.7 default to tracking the preamplifier “ON” status. However when in independent
mode it may be useful for the “Ampon” output to be assigned to the amplifier. Select using a left click on the Amp tab.

Preset Setup Window
■ Preset Programming
Preset programming effects all zones on the MZA-4.7. There are six momentary preset buttons – Preset 1 - Preset 6.
These presets are stored in the MZA-4.7, and may be setup using the IMC setup window.
Left mouse click over “Set up preset 1” and change any MZA-4.7 function i.e. On status, volume level, source selection,
even bass, treble etc. If Preset 1 is required to effect changes to the other zones on the MZA-4.7, then either change the
main window’s zone or open other IMC main window instances and make the required changes, then left click over the
“Default” selection to exit. Preset 1 is now programmed and will be set to the programmed preset states whenever the
MZA-4.7 receives the preset 1 IR control string, or RS232 command.
The process is the same for all other presets.
The Preset may be re-named – Right click on the Preset button in IMC’s main window: Opens the name edit window.
Enter the new text and click OK to save and exit.
The name is also added next to the “Set up preset” in the Preset Setup Window.
■ Page Preset

and exit.
If a door bell sound has been uploaded to the amplifier, then it may be optionally included in the preset by clicking the
“Sound” tab. All zones will be automatically set to input S8.
Whenever a contact across the PG and 0V terminal is closed the amplifier will assume the programmed states, and if
“Sound” was selected the uploaded wav file will be played in a continuous loop for the duration of the contact closure.
When the contact opens the amplifier reverts to its previous settings.
■ Alarm Clock Programming
An alarm clock event may be included in a preset.
In the Preset Setup window left Click a spare “Set up preset” – for this example Preset 6 is selected.
Left click the “Alarm Enable” in the Schedule panel.
