Operating the SUB135S Subwoofer
LFE Input: Connect to LFE/Subwoofer
Outputon rear panel of DCR600 receiver
using the single-lead RCA cable with brown
connectors.
LED: Lights green when a low-frequency
signal is present and the subwoofer is playing.
Lights red when no low-frequency audio signal
is present to indicate that the subwoofer is
plugged in, powered on and in the Standby
mode.
Power Switch: Turn the power switch to
the “
•
” (dot) position to power the unit on. The
SUB135S subwoofer will automatically turn
itself on and go into Standby (Sleep) mode
when left in the On position. When your
DCR600 is off, or is not sending program materi-
al to the subwoofer, the subwoofer will be in
Standby mode. When the subwoofer senses an
audio signal, it will automatically turn itself on.
If the subwoofer does not sense a signal after
approximately twenty minutes, it will automati-
cally go into Standby mode. If you will be away
from home for an extended period of time, or if
the subwoofer will not be used, turn this switch
off to conserve electricity and for safety.
AC Power Cord: Plug the power cord into
an unswitched outlet.
