Application Example #3
This example shows a two-channel (stereo) setup utilizing two subwoofers and 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, professional CD players, or computer-based audio signal sources. Audio output from the mixer is connected to the subwoofer input of each channel. Each subwoofer�s FULL RANGE LINE OUT connector is used to connect to its respective top-box. Turn ON the top-box�s 100 Hz LOW-CUT FILTER. Alternately, the top-boxes could be connected to the subwoofer�s 100 Hz LOW-CUT OUT and the top-box 100 Hz LOWCUT FILTER turned off. The only possible issue with this method of connection is unexpected noises (turn-off thumps) if the subwoofer is powered down before the top-boxes. If connected as shown, power sequencing is not an issue.

Ensure the top-boxes have their 100 Hz LOW-CUT FILTER switched ON when connecting to the subwoofer�s FULL RANGE LINE OUT as a signal source. Also, be sure to use either the Left or Right (marked L or R) on the subwoofers. If the subwoofer�s input is connected to the Right (R) channel connector and the output to the top-boxes is connected to the Left (L) channel connector, no signal will reach the top-box (no sound from the top-box).
