Select LARGE for full-range front speakers to deliver full frequency re-
sponse to the front left and right outputs. Selecting SMALL activates a 12dB
per octave highpass filter and automatically routes low frequency informa-
tion to the subwoofer output. Choices of 40, 80 and 120 Hz are available for
the -3dB point. The SMALL setting is recommended unless your speakers
are capable of handling full audio signals, or are equipped with their own
crossovers.
