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.

SUB135S Test Set Up and Procedure
SYSTEM AURAL SWEEP TEST
Equipment needed:
• Function/signal generator/sweep generator
• Integrated Amplifier
• Multimeter
General Unit Function (UUT = Unit Under Test)
1. From the signal generator (set initially at 0 volts), connect one line level (RCA) cable to the SUB135S LFE
jack on the UUT.
2. Plug in the power cord; turn the power switch ON. LED should be Red.
3. Turn up the generator and adjust to 300mV, 40 Hz. LED should now be Green.
4. Immediate bass response should be heard and felt from port tube opening.
Sweep Function
1. Follow steps 1-4 above, using a sweep generator as a signal source.
2. Sweep generator from 20Hz to 1kHz. Listen to the cabinet and drivers for any rattles, clicks, buzzes or
any other noises. If any unusual noises are heard, remove woofer and test.
Driver Function (Woofer)
1. Remove woofer from cabinet; detach the + and - wire clips.
2. Check DC resistance of woofer; it should be 3.4 ohms ±10%.
3. Connect a pair of speaker cables to driver terminals. Cables should be connected to an integrated
amplifier fed by a signal generator. Turn on generator and adjust so that speaker level output is 5.0V.
5. Sweep generator from 20Hz to 1kHz. Listen to driver for any rubbing, buzzing, or other unusual noises.
Caution: take care to replace the + and - wire clips on the correct terminals, as they are the same size. Red wire
should connect to the red dot on the terminal.
