Application Example #1

Application Example #1

This example shows a two-channel (stereo) setup utilizing two top-boxes.

Audio signals for the Left and Right channels are supplied by the mixer console. This signal source can be just about any variable-output level audio source, such as DJ mixers, profes- sional CD players, or computer-based audio signal sources.

Audio output from the mixer’s Left channel is connected to the Left top-box’s FULL RANGE LINE IN connector. Audio output from the mixer’s Right channel is connected to the Right top- box’s FULL RANGE LINE IN connector. Turn off each top-box’s

100Hz LOW-CUT FILTER. This will provide more low-frequency content (bass) in the absence of a subwoofer.
