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. Figure 6: SC-1250 Remote.

•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.
