SERVICE ON THIS EQUIPMENT IS TO BE PERFORMED BY EXPERIENCED REPAIR TECHNICIANS ONLYClick on any item to open that pageALL BOARDS4OverviewThe SRS1500 is a high output active subwoofer system. It features a high-precision 15”transducer combined with application specific amplifier technol

6、ogy. The system iscomposed of a single, compact subwoofer cabinet with built-in control and amplifierelectronics.The SRS1500 accepts a stereo line-level signal via female XLR input jacks. Male XLR Thrujacks are provided for daisy-chaining the signal to additional SRS1500 cabinets. The built-in cross

7、over separates the low frequencies from the high frequencies, and routes the highfrequencies 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 apair of passive speakers such as the Mackie

8、Designs M1400i and C300s. A Phase switchgives you the option of reversing the phase to the full-range speakers by 180. ASubwoofer Level control allows you to adjust the balance between the subwoofer andthe full-range speakers.The built-in amplifier produces up to 600 watts of power. The amplifier mo

9、dule sits on alarge heatsink that eliminates the need for fans, dramatically extending life expectancy,and eliminating maintenance cycles. A tremendous benefit of having the amplifierlocated within the subwoofer cabinet is the speed with which power is delivered to thewoofer.The cabinet is construct

10、ed with 18mm thick multi-layered birch plywood. Carryinghandles are integrated into each side for easy loading and transport.POWER SwitchUse this switch to turn the SRS1500 on and off. Make sure the signal sources level controlis turned down before you turn it on.AC ReceptacleThis is where you conne

11、ct the AC linecord to provide AC power to the SRS1500s built-inpower amplifiers. Plug the linecord into an AC socket properly configured for yourparticular model.THERMAL IndicatorThe SRS1500 has a thermal protection circuit that monitors the internal temperature of theamplifier and heatsink. If the

12、temperature should exceed a safe operating level, thesignal is muted and the THERMAL indicator lights. When the temperature cools to a safelevel once again, the thermal protection circuit deactivates and normal operationcontinues.Note: Activation of the thermal protection circuit is an indication th

13、at you must takesteps to avoid continued thermal problems.POWER IndicatorWhen the POWER switch is turned on and the linecord is connected to an active ACpower supply, this indicator lights green. The blue LED on the front of the cabinet worksin the same way.5POWERTHERMALTHRU(FULL RANGE OUTPUT)HIGH P
