Connect the supplied microphone for the Auto-EQ feature to this mini-jack.

This is the eye that receives infrared commands from the supplied remote.
(5) Low-pass Crossover
Use these up and down buttons to select the high-frequency range at which you wish to cut off the
signal to the subwoofer. The frequency is indicated on the LED display briefly, then the display reverts
to showing the subwoofer’s volume. 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 9 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-
1250 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.
(8) Optional Rack Mount
These detachable ears allow the SC-1250 to be rack mounted.
