1 FILTER switch and FREQUENCY adjustment knob
(One pair for each channel)
Use these controls to select the filter type and adjust the cutoff
frequency on each channel (A and B). You use the FILTER
switch to select the filter, as follows.
SUB
OFF
WOOFER LOW CUT
OFF ...................... Do not use any filter.
SUBWOOFER..... Use a low-pass filter. The amplifier outputs
the frequencies that are lower than the cut-
off set by the FREQUENCY adjustment
knob.
LOW CUT ........... Use a high-pass filter. You can use this set-
ting to filter out unneeded low or subsonic
frequencies.
If you select SUBWOOFER or LOW CUT, you can then use
the FREQUENCY adjustment knob to adjust the cutoff fre-
quency. The adjustment range is 25 Hz to 150 Hz.

If you set this switch ON, the amplifier adds low-frequency
compensation so as to enhance speaker output. The results (the
actual change in the low-frequency balance) will vary accord-
ing to the speaker type. Note that this switch is effective only if
the FILTER switch is set to OFF.
