SC-600 Amplifier User’s Manual
(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-600 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 of both the main
speakers and subwoofer. The default volume is 30.
Note: Volume can also be 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)
These ears can be attached to the SC-600 amp to allow standard 19” rack mounting.

(9) Thru Jacks
These RCA connectors are for passing along the same signal that goes into your subwoofer
to a second “daisy-chained” system. The signal from these RCA connectors is the same as
the input signal.
(10) Line Input / LFE Input
Connect these jacks to the LINE OUT preamp output, LFE output, or subwoofer output jacks
of your receiver/processor. If using the LFE output from your receiver or processor, plug
the single cable into the jack labeled LFE input or, for more signal, use a “Y” connector
(optional) and feed the signal into both “R” and “L” inputs. Examples of these types of
connections can be found in Figures 2A and 2B.
