The features of the SC-1250 remote control are listed below.
• POWER — This button forces your SC-1250 unit 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, press the power switch on
the front panel.
Note: The master power switch on rear panel must be on in order
for the front power button to function.
• MUTE — This button mutes the subwoofer. The LED on the
amplifier will show 00 if the unit is muted. To unmute the
subwoofer, press the MUTE button again and the original volume
setting shows on the LED.
• EQ — This button automatically EQs the subwoofer using a 7 band internal graphic equalizer.
To use this feature, first plug the supplied microphone into the Mic-In jack on the back panel
of the subwoofer and place the mic in your preferred listening position. Then, by pressing EQ
on the remote, the subwoofer emits 12 “sweep tones” that cover the frequencies between
20 and 150 Hz. The LED displays “AU” during the Auto-EQ process. After the sweeps are
complete, the unit saves its EQ settings and returns to normal operation. To prevent
accidental invocation of the EQ feature, you must hold down the EQ button for 2-3 seconds
before the EQ sweeps begin.
Note: Each time the EQ feature is utilized, the EQ settings for the SC-1250 are reset. If the
microphone is not plugged in, the SC-1250 will emit one or two sweep tones then cease the
EQ operation. In this case, the previous EQ settings will be preserved.
• PHASE — These buttons allow you to optimize the subwoofer performance for the location
and your listening position. Select the switch position at which you hear the most bass. The
LED will show the phase selected by showing “PH” followed by the phase number.
• LIGHT — If you wish, you can deactivate the numeric LED on your SC-1250. To do this, press
the LIGHT button on your remote. To reactivate the LED, press the LIGHT button again.
• NIGHT — Night mode limits the maximum output of the subwoofer for late night listening
or to be more considerate of close neighbors. Press the night button to turn the night
mode feature on or off. Night mode, when active, is indicated by the reduced intensity of the
power LED.
• VOLUME CONTROL — This control allows you to balance the output from the subwoofer to
the main speakers in your system. This control should be set to achieve similar volume level
from between both the main speakers and subwoofer. When pressing volume up or down,
the volume level is shown on the numeric LED on the front panel.
Note: The volume can also be adjusted via the volume buttons on the front panel of the
amplifier. These buttons have the same effect as pressing the up and down volume buttons on
your remote.
