Figure 1: Front Panel Connections of the SC-600D amplifier.
Following are brief descriptions of the controls described in Figure 1. More detail on these
controls can be found in the next section.
(1) Power Switch
This button forces your SC-600D amplifier into standby mode. The power LED turns amber,
the numeric LED shuts off, and the amplifier puts out no power. The unit will remain in this
mode until the POWER button is pressed again. To fully deactivate (i.e. power down) the unit,
use the main power switch on the back panel.
(2) Power LED
This LED illuminates when the power is on. Blue indicates normal operation. The LED turns
amber when the unit is in standby mode or the remote has been used to deactivate the unit,
and dims when the unit is in night mode.
(3) Mic Input
Connect the supplied microphone for the Auto-EQ feature to this mini-jack input.
(4) Remote Eye
This is the eye that receives infrared commands from the supplied remote.
(5) Crossover
Use these Up and Down buttons to select the frequency below which all signals will be routed
to the subwoofer (for example, 80 Hz), rather that to the main speakers. The frequency is
indicated on the LED display, then the display reverts to showing the subwoofer’s volume
level. The slope is fixed at 24 dB/octave. To deactivate the crossover, press BOTH the Up
and Down crossover buttons at the same time – two dashes on the display indicate the
crossover is deactivated and the woofer plays all frequencies presented to it. Please see
page 8 for a more detailed discussion on crossovers.

(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
T
hese 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 SubOut 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-600D amp to allow standard 19” rack mounting.

Following are brief descriptions described in Figure 2. More detail on these controls can be
found in the next section.

Figure 2: Rear Panel Connections of the SC-600D amplifier.
(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.
