FRONT PANEL CONTROLS

POWER—LED illuminates when the system is turned on.

BASS BOOST—select a boost level between -3dB and +3dB to enhance the bass performance for your sound system. BASS BOOST is NOT free! Every 3dB of boost costs you twice as much in power.

Make sure to set the final volume after setting the Bass Boost to work best with your system. More is NOT always better!

CROSSOVER—select a Low Pass crossover frequency from 30Hz to 150Hz.

VOLUME—select a volume for the system that works best with your BASS BOOST setting and your listening preference.
