subwoofer with respect to the main speakers. If the
subwoofer is out of phase with the main speakers, bass
response is at a reduced performance level and may sound

response is at an optimal level.

input signal for approximately 10 minutes, it will
switch to stand by mode until it receives a further

LOOP RCA inputs.
NOTE: These inputs are typically used for signal
output to main speakers or for daisy chaining.
