Lend Me Your Ears
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.
Duration Per Day Sound Level dBA, Typical
In Hours Slow Response Example
8 90 Duo in small club 692 4 95 Subway Train 397 2 100 Very loud classical music
1.5 102 1 105 Patrice screaming at Ron about deadlines
0.5 110
0.25 or less 115 Loudest parts at a rock concert
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.
The SRS1500 can produce a
maximum SPL of
123 dB @ 1m

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.

REAR PANEL DESCRIPTION
The SRS1500 has several connectors and
features that you should understand.
POWER Switch
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 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.

FULL RANGE INPUT
These are female XLR-type connectors that accept a balanced line-level signal from a mixing console or other signal source.
THRU (FULL RANGE OUTPUT)
These are male XLR-type connectors that produce exactly the same signal that is connected to the
FULL RANGE INPUT
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.
PHASE
This switch reverses the phase of the signal at the
HIGH PASS OUTPUT
Depending on the placement of the SRS1500 subwoofer relative to the full­range speakers, you may get a better low-frequency response in the room if you reverse the phase of the signal. Experiment with this switch to determine which position sounds best.

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.

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.

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 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 outside the United States can be obtained through local dealers or distributors.
