SWA200 SUBWOOFER AMPLIFIER Installation & Operation Manual
Introduction Congratulations on your purchase of an Destination Audio SWA200 subwoofer amplifier! Your subwoofer amplifier is the result of many years of research and development dedicated to producing high quality products for home audio and audio/video systems. This manual contains features, setup recommendations and specifications for the Destination Audio SWA200 subwoofer amplifier.
Front Panel (continued) 5. Crossover: This button allows the amplifier’s internal low-pass filter to be defeated when using an external crossover, or when the crossover is not needed. When defeated (off), the subwoofer output will play the full-range of the audio signal. This button has no effect on the high level inputs and outputs shown in figure 2, #10 and #11. The high level output (figure 2, #10) has a 100Hz high pass filter and is not adjustable or defeatable. 6.
Rear Panel The following describes the control functions of the rear panel of the amplifier (refer to figure 2). 8. Line/LFE Input: These RCA type terminals are for the pre-amp level input signals coming from a processor or preamplifier labeled “subwoofer” or “LFE.” IMPORTANT! Use either the Line Level inputs or the “Speaker Level” inputs separately. DO NOT use both, as damage to the receiver and/or the Subwoofer Amplifier may result.
Rear Panel (continued) 14. Fuse Access: This is the power fuse access. WARNING! In the event the fuse must be replaced, the replacement fuse must match exactly the original fuse value. If the replacement fuse is not of the same value, damage to the Subwoofer Amplifier may result. CAUTION! Before replacing the fuse, disconnect the power cord from the power receptacle. 15.
