ADJUSTABLE LOW-PASS, HIGH-PASS, AND PHASE CONTROLS INSTALLATION CONSIDERATIONS Variable low-pass and high-pass filters divide the incoming stereo audio spectrum into separate signal paths for the mono subwoofer reproduction and stereo pass-through to a pair of satellite loudspeakers. A fully-adjustable (0-to-180 degree) phase control ensures optimal system integration, no matter where the SW300 is placed in the room.
SW300 PLACEMENT CONTROLS AND CONNECTORS THE BOUNDARY EFFECT OPERATION CONTROLS Placing an SW300 in a corner can powerfully affect the way a listener perceives bass response. Known as the boundary effect, a placement close to a wall/ceiling boundary or near a corner-wall boundary will emphasize certain bass frequencies, while canceling others. This effect can make the SW300 sound excessively boomy and inaccurate to some listeners, while to others it just seems like more bass sound.
SIGNAL CONNECTORS AND POWER CONTROLS signals are present. When signals are absent, the SW300 will enter the standby mode. The SW300’s signal connectors and power controls are located on the unit’s rear panel, as shown in Figure 2.
