Application Example #2
This example shows a two-channel (stereo) setup utilizing one
subwoofer 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, profes-
sional CD players, or computer-based audio signal sources.
Audio output from the mixer is connected to the subwoofer’s
Left (L) and Right (R) channels. The subwoofer’s R and L FULL
RANGE LINE OUT connectors are used to connect to its respec-
tive top-box. Turn ON each top-box’s 100 Hz LOW-CUT FILTER.
Alternately, the top-boxes could be connected to the sub-
woofer’s 100 Hz LOW-CUT OUT and the top-boxes 100 Hz
LOW-CUT FILTERs turned off. The only possible issue with this
method of connection is unexpected noises (turn-off thumps) if
the subwoofer is powered up or down while the top boxes are
on. If connected as shown, power sequencing is not an issue.

Use only high-quality balanced cables for inter-
connecting the audio equipment.
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 sig-
nal source.
Also, be sure to keep Left and Right (marked L or
R) channels segregated properly so that sound-
stage imaging remains consistent.
