Exposure to extremely
high noise levels may cause
According to OSHA, any exposure in ex-
cess of these permissible limits could result
in some hearing loss. To ensure against po-
tentially dangerous exposure to high
permanent hearing loss. In-
sound-pressure levels, it is recommended
that all persons exposed to equipment ca-
pable of producing these levels use hearing
protectors while this unit is in operation.
Ear plugs or protectors in the ear canals or
over the ears must be worn when operating
this amplification system in order to pre-
vent a permanent hearing loss if exposure is
in excess of the limits set forth here.
dividuals vary considerably
in susceptibility to noise-
induced hearing loss, but nearly everyone
will lose some hearing if exposed to suffi-
ciently intense noise for a period of time.
The U.S. Government’s Occupational
Safety and Health Administration (OSHA)
has specified the permissible noise level ex-
posures shown in this chart.

LIMIT Indicator
REAR PANEL DESCRIPTION
The SA1232 has a built-in limiter that
prevents the amplifier outputs from clip-
ping or overdriving the transducers. The
LIMIT indicator lights when the limiter is
activated. It’s okay for the LIMIT indicator
to blink occasionally, but if it blinks fre-
quently or lights continuously, turn down
the level control until the LIMIT indicator
only blinks occasionally.
MAIN INPUT
This is a female XLR-type connector that
accepts a balanced line-level signal from a
mixing console or other signal source.
LOOP OUT
This is a male XLR-type connector that
produces exactly the same signal that is
connected to the MAIN INPUT jack. Use it
to daisy-chain several SA1232s together off
the same signal source.
THERMAL Indicator
There is also a thermal protection circuit
that monitors the internal temperature of
the amplifiers and heatsink. If the tempera-
ture should exceed a safe operating level,
this indicator lights and the signal is muted
to allow the amplifiers to cool. When the
temperature cools to a safe level once again,
the thermal protection circuit deactivates
and normal operation continues.
Level Control
This controls the overall signal level at the
input to the built-in power amplifiers. It
ranges from –15 dB to +5 dB of gain. The
center detent is 0 dB (unity gain).
Power ON Indicator
Note: Activation of the thermal protection
circuit is an indication that you should take
steps to avoid continued thermal problems.
See “Thermal Considerations” on page 8.
When the power switch is turned on,
and the linecord is connected to an active
AC power supply, this indicator lights green
to let you know that you’re ready to rock
and roll. The cool blue LED on the front of
the cabinet works in the same way.
Power Switch
Use this switch to turn the SA1232 on
and off. Make sure the level control is
turned down before you turn it on.
SIGNAL Present Indicator
This LED illuminates whenever there is
a signal present at the MAIN INPUT connec-
tor on the rear panel. It senses the signal
just after the Level control, so if the Level
control is turned down, the SIGNAL Present
indicator turns off.
AC Receptacle
This is where you connect the AC
linecord to provide AC power to the
SA1232’s built-in power amplifiers. Plug
the linecord into an AC socket properly
configured for your particular model.

PLACEMENT
CONNECTIONS
The SA1232 speaker is designed to sit on
the floor or stage.
The SA1232 has one female XLR input
that accepts a balanced line-level signal.
When connecting a balanced signal, be sure
it’s wired per AES (Audio Engineering So-
ciety) standards:
WARNING: The
cabinet has no rigging
points and is not suit-
able for rigging.
NEVER attempt to
suspend the SA1232 by
its handles.

Pin 1
The SA 1232 should never be pole-mounted.
You can create a horizontal array by plac-
ing the cabinets side-by-side. However, you
should have a good understanding of the re-
lationship between the splay angle (the
angle between the facing sides of the cabi-
nets), the on-axis power, and frequency
cancellation effects between cabinets.
When two cabinets are placed side-by-
side, the actual splay angle is 20º (determined
by a 10º angle on each cabinet side). As the
splay angle increases toward the angle of
horizontal coverage (90º for the SA1232),
the on-axis power decreases, but the
frequency response becomes smoother as
the comb-filtering effects (caused by the
interaction in the area of double-coverage)
decrease.
Balanced XLR Connectors
There is also a male XLR connector la-
beled LOOP OUT. This is also wired
according to the above AES standard.
The LOOP OUT connector allows you to
connect more than one SA1232 to your sys-
tem. Simply plug the signal source (i.e.,
mixer output) into the first MAIN INPUT
jack, and patch that speaker’s LOOP OUT
jack to the next MAIN INPUT jack, and so
on, daisy-chaining multiple speakers.
The LOOP OUT jack is wired straight
from the MAIN INPUT connector — there is
no electronic circuitry between — so the
signal coming out of the LOOP OUT jack is
exactly the same as the signal going in.
As with any powered
components, protect
them from moisture. If
you are setting them up
outdoors, make sure
they are under cover if
you expect rain.

AC POWER
Be sure the SA1232 is plugged into an
outlet that is able to supply the correct volt-
age specified for your model. If the voltage

should drop below 97% of the specified line 230V
voltage, the built-in amplifiers will no
longer be able to supply rated power. (They
will continue to operate down to 80% of
the rated line voltage, but won’t reach full
power, resulting in lower headroom.)
Be sure the electrical service can supply
enough amperage for all the components
connected to it.
We recommend that a stiff (robust) sup-
ply of AC power be used because the
amplifiers place high current demands on
the AC line. The more power that is avail-
AC sags, or lack of current can be au-
dible. When running into this type of
problem, the anomaly generally encoun-
tered is similar to that of a processor
compressing the input signal very hard.
This is caused by the inability of the toroid
transformer to recharge the amplifier ca-
pacitors fast enough. As a result, the audio
performance gets very thin sounding and
you must lower the input level in order for
the system to recuperate. This is a very com-
able on the line, the louder the speakers will mon problem for the pro-audio industry in
play and the more peak output power will
be available for cleaner, punchier bass. A
suspected problem of “poor bass perfor-
mance” is often caused by a weak AC
supply to the amplifiers.
general. When you begin talking about am-
plifier systems that deliver high power
levels (more than 1,000 watts), the limita-
tions of 115V AC service create problems.
Here are some basic calculations for
some high power amplifiers:

SA1232 systems are available in 115V

signs specifies a specific amount of

If the signal reproduced were a full band-
width sine wave, then the above data would
be true at full output with an absolutely flat
signal. An audio signal presents a distinct
problem when it comes to the reproduction
of transient signals found in the typical pro-
grams. For a very short time, the amplifier’s
power supply could require up to four times
the amperage as it tries to reproduce a 6 dB
peak. This is especially true of subwoofer
amplifier systems trying to reproduce fre-
quencies below 50 Hz, which is the frequency
that AC power usually travels at. The
SA1232 amplifiers have extremely robust
toroidal transformers and use a large num-
ber of capacitors. Toroidal power supplies
have one huge advantage over other types
of supplies, which is their ability to provide
higher output beyond their nominal rating.
For a very short period of time, a well designed
2500 watt transformer can deliver up to
amperage service availability for individual
active cabinets. It is a good rule of thumb,
especially in countries using 115V AC
power, to know precisely the amount of
voltage/amperage service available to oper-
ate your active speaker systems safely and
to their full output capacity. We have pro-
vided specifications relative to minimum
amperage requirements that should be used
as a general guideline. Additionally, it is
necessary to comprehend the demands put
upon the AC service when running the
cabinets for prolonged periods of time at
maximum output levels. Depending on the
source material and level, cabinets running
on 115V AC can demand as much as 20
amps of peak amperage service. Depending
on the type of service available, this could
be beyond the capability of your AC system
and produce unwanted audible by-products.

5000 watts of power. This provides the
headroom necessary to deal with the peak
transient signals that must be reproduced.
The AC current supplied to the active
speaker is especially critical to the overall
performance of the audio system. In light of
the limitations created by standard 115V
service, we have a list of suggestions that
will help you avoid problems.
THERMAL
CONSIDERATIONS
The SA1232 has three powerful built-in
amplifiers capable of producing a combined
1300 watts of power. As amplifiers produce
heat, it is important to dissipate the heat as
quickly as possible. This results in increased
reliability and longevity for the amplifier.
The amplifier module is mounted on a
large heatsink, which is cooled by convec-
tion where cool air is drawn through its
fins, carrying the heat away. In order for
this convection cooling to work efficiently,
it is important to provide adequate airspace
behind the loudspeaker. When you position
the SA1232, we recommend leaving at least
six inches of air space behind it.
AC Recommended Checklist

Always check your installation/set up
for available AC supply rated circuit
amperage
•
•
Locate the main electrical board for
breaker location
Make sure you are not sharing the
AC supply for amplifiers with lighting
or other services
In the unlikely event of the amplifier
overheating, a built-in thermal switch will
activate, which mutes the signal and lights
the THERMAL LED. When the amplifier
has cooled down to a safe operating tem-
perature, the thermal switch resets itself,
and the SA1232 resumes normal operation.
If the thermal switch activates frequently,
try turning down the level control a notch or
two on the mixing console (or the back of the
SA1232) to avoid overheating the amplifier.

The 230 volt AC systems are more
stable and run into far fewer current supply
problems. In fixed applications where 220-
230 volt service is available, we highly
recommend using the SA1232 in 230 volt
mode. The power supply in the SA1232 can
be switched between 115 volt and 230 volt

SERVICE INFORMATION
•
Is the THERMAL indicator lit red on
the rear panel? Make sure there is at
least six inches of free space behind the
SA1232.
Warranty Service
If you think your loudspeaker has a
problem, please do everything you can to
confirm it before calling for service, includ-
ing reading through the following
Troubleshooting section. Doing so might
save you from being deprived of your
Mackie loudspeaker.
Of all Mackie products returned for ser-
vice (which is hardly any at all), many are
coded “CND” — Could Not Duplicate—
which usually means the problem lay some-
where else in the system. The following
troubleshooting tips may sound obvious,
but here are some things you can check:
Poor bass performance
•
Check the polarity of the connections
between the mixer and the loudspeak-
ers. You may have your positive and
negative connections reversed at one
end of one cable, causing one loud-
speaker to be out-of-phase.
Poor sound
•
Is it loud and distorted? Make sure that
you’re not overdriving a stage in the
signal chain. Verify that all level controls
are set properly.
Is the input connector plugged com-
pletely into the jack? Be sure all
connections are secure. It’s a good idea
to periodically clean all electrical
connections with a non-lubricating
electrical contact cleaner.
Troubleshooting
No power
•
• Our favorite question: Is it plugged in?
Make sure the AC outlet is live (check
with a tester or lamp).
• Our next favorite question: Is the POWER
switch on? If not, try turning it on.
• Is the POWER LED on the rear panel
glowing green? If not, make sure the AC
outlet is live. If so, refer to “No sound”
below.
Noise
•
Make sure all connections to the active
loudspeakers are good and sound.
•
Make sure none of the signal cables are
routed near AC cables, power trans-
formers, or other EMI-inducing devices.
Is there a light dimmer or other SCR-
based device on the same AC circuit as
the SA1232? Use an AC line filter or
plug the SA1232 into a different AC
circuit.
• The internal AC line fuse may be
blown. This is not a user serviceable
part. If you suspect the AC line fuse is
blown, please see the “Repair” section
next.
•
No sound
• Is the input LEVEL control for the
input source turned all the way down?
Verify that all the volume controls in the
system are properly adjusted.
Hum
•
Try disconnecting the cable connected
to the MAIN INPUT jack. If the noise
disappears, it could be a “ground loop,”
rather than a problem with the SA1232.
Try some of the following troubleshoot-
ing ideas:
Use balanced connections throughout
your system for the best noise rejection.
Whenever possible, plug all the audio
equipment’s linecords into outlets which
share a common ground. The distance
between the outlets and the common
ground should be as short as possible.
• Is the signal source working (and
making union scale)? Make sure the
connecting cables are in good repair and
securely connected at both ends. Make
sure the output volume (gain) control
on the mixing console is turned up
sufficiently to drive the inputs of the
speaker.
• Make sure the mixer does not have a
Mute on or a Processor loop engaged. If
you find something like this, make sure
the volume/gain is turned down before
disengaging the offending switch.

call for your RA number. The product
MUST be packaged in its original
packing box and have the RMA number
appear on the box. Once it is repaired,
we’ll ship it back to you the same way in
which it was received. This paragraph
does not necessarily apply to non-
warranty service.
Service for the SA1232 is available only
from one of our authorized domestic ser-
vice stations or at the factory service center
located in Whitinsville, Massachusetts. Ser-
vice outside the United States can be
obtained through local dealers or distributors.
If your SA1232 needs service, please fol-
low these instructions:
1. Review the preceding troubleshooting
suggestions. Please.
2. Call Tech Support at 1-800-258-6883,
7am to 5pm PST, to explain the problem
in detail. They will ask you all sorts of
impertinent questions in the hope of
sorting out the problem. If it appears
that the SA1232 needs repair, request
an RA (Return Authorization) number.
Have your loudspeaker’s serial number
ready. You must have an RA number
before you can obtain service at the
factory or an authorized service center.
CARE AND
MAINTENANCE
Your Mackie loudspeak-
ers will provide many
years of reliable service if
you follow these guide-
lines:
• Avoid exposing the loudspeakers to
moisture. If they are set up outdoors, be
sure they are under cover if you expect
rain.
• Avoid exposure to extreme cold (below
freezing temperatures). If you must
operate the loudspeakers in a cold
environment, warm up the voice coils
slowly by sending a low-level signal
through them for about 15 minutes
prior to high-power operation.
3. Keep this user’s manual. We don’t need
it to repair the loudspeaker.
4. Pack the loudspeaker in its original
packaging, including protective wrap,
endcaps, and box. This is very impor-
tant. When you call for the RA number,
please let Tech Support know if you
need new packaging. Mackie is not
responsible for any damage that occurs
due to non-factory packaging.
• Use a slighty damp cloth with a mild
soap solution to clean the cabinets. Only
do this when the power is turned off.
Avoid getting moisture into any of the
openings of the cabinet, particularly
where the drivers are located.
5. Include a legible note stating your name,
shipping address (no P.O. boxes),
daytime phone number, RA number,
and a detailed description of the prob-
lem, including how we can duplicate it.
6. Write the RA number in BIG PRINT
on top of the box.
7. Ship the loudspeaker to us. We suggest
insurance for all forms of cartage. Ship
to this address:
