(6) LED Numeric Indicator
This LED supplies information on volume, crossover, woofer type, and other information. The “light”
button on the remote deactivates this display. Upon startup, the display shows the model of subwoofer
the SC-600D amp is controlling, then reverts to the volume indicator.
(7) Volume Control
These buttons allow you to balance the output from the subwoofer to the main speakers in your system.
The volume should be set to achieve similar volume level from between both the main speakers and
subwoofer. The default volume is 30.
Note: Volume is also controllable by using the supplied remote.
WARNING: Some manufacturers preset their receivers with the Sub-Out (a.k.a. LFE) channel signal
at a minimum level. It is very important to verify that your receiver Sub-Out channel is set to the same
output level as your front right and left channels. Refer to your receiver manual for the individual channel
level adjustment procedure. If your receiver Sub- Out channel is set too low, the subwoofer may appear
to have a weak output, it may sound noisy or distorted, and the Auto On/Off feature may not operate
properly.
(8) Optional Rack Mount Ears (Included)
Following are brief descriptions described in Figure 2. More detail on these controls can be found in the
next section.

“daisy-chained” subwoofer. The signal from these RCA connectors is the same as the input signal.
