The SWA801z is a high-output active subwoofer system. It features two high-precision 18" transducers combined with applicationspecific amplifier technology. The system is composed of a single, compact subwoofer cabinet with built-in control and amplifier electronics. Connecting and setting up the SWA801z is a breeze, even for your brother-in-law. It accepts a stereo or mono line-level signal via female XLR input jacks. Male XLR Thru jacks are provided for daisy-chaining the signal to additional SWA801z 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, or to an amplifier powering a pair of passive speakers. A Phase switch gives you the option of reversing the polarity of the signal to the subwoofer by 180º. A Subwoofer Level control allows you to adjust the balance between the subwoofer and the fullrange speakers. The built-in amplifier produces 800 watts of continuous power. The amplifier module sits on a heatsink that eliminates the need for fans, dramatically extending the amplifier's life expectancy, and eliminating maintenance cycles. A tremendous benefit of having the amplifier located within the subwoofer cabinet is that the SWA801z functions as a system, optimizing acoustic, electronic, and mechanical designs to achieve the highest level of performance and value. The cabinet is constructed with 15 mm thick multi-layered birch plywood. Carrying handles are integrated into each side for easy loading, and casters are attached for easy transport.

REAR PANEL DESCRIPTION 1. POWER Switch Use this switch to turn the SWA801z on and off. Make sure the signal source's level control is turned down before you turn it on. 6. POWER Indicator 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. 2. AC Receptacle This is where you connect the AC linecord to provide AC power to the SWA801z's built-in power amplifier. Plug the linecord into an AC socket properly configured for your particular model. 7. FULL RANGE INPUT These are female XLR-type connectors that accept a balanced line-level signal from a mixing console or other signal source. 3. LIMIT Indicator The SWA801z has a built-in limiter that prevents the amplifier outputs from 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 frequently or lights continuously, turn down the level control until the LIMIT indicator only blinks occasionally. 8. 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 SWA801z's together off the same signal source. 9. HIGH PASS (MID/HIGH FREQ) OUTPUT These are male XLR-type connectors that produce the frequencies above 10 Hz. Connect these to a pair of full-range active speakers or to an amplifer/passive speaker combination. The SWA801z reproduces the frequencies below 10 Hz. 4. SIGNAL Present Indicator This LED illuminates whenever there is a signal present at the FULL RANGE INPUT connector on the rear panel. 5. THERMAL Indicator The SWA801z has a thermal protection circuit that monitors the internal temperature of the amplifiers and heatsink. If the internal temperature should exceed a safe operating level, this indicator lights and the signal is muted to allow the amplifier to cool. When the temperature cools to a safe level once again, the thermal protection circuit deactivates and normal operation resumes. 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 7. 10. SUBWOOFER LEVEL Control This adjusts the subwoofer level. The center detent position provides 15 dB of headroom with a nominal + dBu input signal. Use this as a starting point for setting the balance between the subwoofer and the main speakers. 11. PHASE This switch reverses the polarity of the subwoofer output. Depending on the placement of the SWA801z subwoofer relative to the full-range speakers, you may get a better low-frequency response in the room if you reverse the polarity of the subwoofer's signal. Experiment with this switch to determine which position sounds best.
