Exposure to extremely
high noise levels may cause
permanent hearing loss. Individuals vary considerably
in susceptibility to noiseinduced hearing loss, but nearly everyone will
lose some hearing if exposed to sufficiently intense noise for a period of time. The U.S.
Government’s Occupational Safety and Health
Administration (OSHA) has specified the permissible noise level exposures shown in this
chart.

According to OSHA, any exposure in excess
of these permissible limits could result in some
hearing loss. To ensure against potentially
dangerous exposure to high sound-pressure
levels, it is recommended that all persons
exposed to equipment capable 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 prevent a permanent hearing loss if
exposure is in excess of the limits set forth here.

INTRODUCTION
Thank you for choosing Mackie Designs’
active sound reinforcement speaker systems.
The SRS1500 is a high output active
subwoofer system. It features a high-precision
15˝ transducer combined with application
specific amplifier technology. The system is
composed of a single, compact subwoofer cabinet
with built-in control and amplifier electronics.
Connecting and setting up the SRS1500 is a
breeze. It accepts a stereo line-level signal via
female XLR input jacks. Male XLR Thru jacks
are provided for daisy-chaining the signal to
additional SRS1500 cabinets. The built-in
crossover separates the low frequencies from
the high frequencies, and routes the high frequencies to the male XLR high-pass output
jacks. Connect these to the inputs of full-range
active speakers such as the Mackie Designs
SRM450s, or to an amplifier powering a pair of
passive speakers such as the Mackie Designs
M•1400i and C300s. A Phase switch gives you
the option of reversing the phase to the full-range
speakers by 180º. A Subwoofer Level control
allows you to adjust the balance between the
subwoofer and the full-range speakers.
The built-in amplifier produces up to 600
watts of power. The amplifier module sits on a
mammoth heatsink that eliminates the need for
fans, dramatically extending life expectancy,
and eliminating maintenance cycles. A tremendous benefit of having the amplifier located
within the subwoofer cabinet is the speed with
which power is delivered to the woofer.
The cabinet is constructed with 18mm thick
multi-layered birch plywood. Carrying handles
are integrated into each side for easy loading
and transport.
Don’t forget to visit our website at www.mackie.com
for more information about this and other Mackie products.
Use this switch to turn the SRS1500 on
and off. Make sure the signal source’s level
control is turned down before you turn it on.
AC Receptacle
This is where you connect the AC linecord to provide AC power to the SRS1500’s
built-in power amplifiers. Plug the linecord
into an AC socket properly configured for
your particular model.
THERMAL Indicator
The SRS1500 has a thermal protection
circuit that monitors the internal temperature of the amplifier and heatsink. If the
temperature should exceed a safe operating
level, the signal is muted and the
THERMAL
indicator lights. When the temperature
cools to a safe level once again, the thermal
protection circuit deactivates and normal
operation continues.
Note: Activation of the thermal protection circuit is an indication that you must
take steps to avoid continued thermal problems. See “Thermal Considerations” on
page 6.
POWER Indicator
When the

jack.
Use it to daisy-chain several SRS1500s together off the same signal source.
HIGH PASS (MID/HIGH FREQ) OUTPUT
These are male XLR-type connectors
that produce the frequencies above 120Hz.
Connect these to a pair of full-range active
speakers or to an amplifer/passive speaker
combination. The SRS1500 reproduces the
frequencies below 120Hz.
SUBWOOFER LEVEL Control
This adjusts the subwoofer level. Use
this control to balance the volume between
the subwoofer and the full-range speakers.
The center detent position is +4 dBu gain,
which is the normal position. Unity gain is
at the 9 o’clock position.

PLACEMENT
THERMAL
The SRS1500 subwoofer is designed to
sit on the floor or on sturdy stands.
A socket is provided on the top of the
SRS1500 for mounting the Mackie
SRM450 active speaker. Use the optional
Mackie speaker mounting pole to mount
the SRM450 on the SRS1500 (see Hookup
Diagram on page 5).
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 SRS1500 is plugged into an
outlet that is able to supply the correct voltage specified for your model. If the voltage
should drop below 97% of the specified line
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) supply of AC power be used because the
amplifiers place high current demands on
the AC line. The more power that is available on the line, the louder the speakers will
play and the more peak output power will
be available for cleaner, punchier bass. A
suspected problem of “poor bass performance” is often caused by a weak AC
supply to the amplifiers.
Never remove the
ground pin on the power
cord of the SRS1500 or
any other component.
This is very dangerous.
CONSIDERATIONS
The SRS1500 has a powerful 600 watt
amplifier built-in. 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 convection where cool air is drawn through it’s
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 SRS1500, we recommend leaving at
least six inches of air space behind it.
In the unlikely event of the amplifier
overheating, a built-in thermal switch will
activate, muting the signal and causing the
THERMAL indicator on the rear panel to
light. When the amplifier has cooled down
to a safe operating temperature, the thermal
switch resets itself, the THERMAL LED
turns off, and the SRS1500 resumes normal
operation.
If the thermal switch activates frequently,
try turning down the level control a notch
or two on the mixing console (or other signal source) or on the subwoofer itself to
avoid overheating the amplifiers.
If the temperature in the room is too
high, it could cause the amplifier to overheat. In this case, you should try aiming a
fan at the rear panel to move more air
across the heatsink panel.
SERVICE INFORMATION
Warranty Service
If you think your subwoofer has a problem, please do everything you can to
confirm it before calling for service, including reading through the following
Troubleshooting section. Doing so might
save you from being deprived of your
Mackie loudspeaker.

Of all Mackie products returned for service (which is hardly any at all), many are
coded “CND” — Could Not Duplicate—
which usually means the problem lay somewhere else in the system. The following
troubleshooting tips may sound obvious,
but here are some things you can check:

way down? Verify that all the volume
controls in the system are properly
adjusted.
•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

•Check the polarity of the connections
between the mixer and the loudspeakers. You may have your positive and
negative connections reversed at one
end of one cable, causing one loudspeaker to be out-of-phase.

•Try switching the
rear panel. This affects the polarity
between the full-range speakers and the
SRS1500 and may improve the lowfrequency response.

•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 completely 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.
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 transformers, or other EMI-inducing devices.
•Is there a light dimmer or other SCRbased device on the same AC circuit as
the SRS1500? Use an AC line filter or
plug the SRS1500 into a different AC
circuit.
Hum
•Try disconnecting the cable connected
to the INPUT jack. If the noise disappears, it could be a “ground loop,”
rather than a problem with the
SRS1500. Try some of the following
troubleshooting 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.
REPAIR
Service for the SRS1500 is available only
from one of our authorized domestic service stations or at the factory, located in
sunny Woodinville, Washington. Service
