B. Connecting to pre out or subwoofer out terminal(s)
For pre out terminal connection, the amplifier must possess at least two sets of pre out
terminals. With some amplifiers with only one set of pre out terminals, connection can
result in no sound from the main left and right speakers. In this case, select the
method of connecting to the speaker terminals.
When connecting Subwoofer out to B1-19 or B1-30, be sure to turn crossover
clockwise to 180 Hz for the best reproduction of low frequencies content.
