Power - Default Auto.
Upon sensing input signal, amplifier powers ON (blue LED) automatically within a few seconds.
Amplifier powers OFF (red LED) to low power consumption Standby mode approximately 15 minutes after last sensed signal.
ON and OFF settings power the amplifier manually.
Crossover - Default LFE.
If sub crossover is set up in Receiver or Pre-Pro, set RackAmp 300 Crossover to default LFE (no
Lowpass Filter). If your electronic components have no sub crossover, e.g. most 2 channel systems, set RackAmp 300
Crossover to the -6dB bass frequency specified for main speakers.
Volume - Default 0.
Set appropriate level for calibrating your AVR or Pre-Pro. For 2 channel systems, set volume level so
subwoofer output matches and blends with your main speakers and amplifier.
Phase - Default 0.
Select anywhere from 0 degrees in-Phase to 180 degrees inverted Phase.
