sor's subwoofer output using an RCA
patch cable.

or Normal operation mode. Lights red
to indicate Standby mode. Lights green

1. Woofer
2. Cabinet
Reduces cabinet-induced colorations
with MDF walls and extensive internal
bracing. Rubber feet/spikes are
attached to the bottom of the cabinet
for optimal stability, accommodating
installations on tile, hardwood, and
carpeted floors. The cabinet’s vinyl
finish does not require routine mainte-
nance. However, cabinet surfaces that
have been marked with fingerprints,
dust, or other dirt can be cleaned using
a soft cloth. Do not use any cleaning
products or polishes on the cabinet or
grille.
