FRONT and REAR “Q” Controls
“Q” Control is active when the highpass crossover is engaged and is centered
on the selected crossover point. The range of operation is 0.7–1.2.
REAR RCA Inputs
RCA cables marked “REAR” from head unit or other line level device should be
connected here. Use both inputs (L & R) for stereo.
REAR Input Switch
In the left (STEREO L-R) position, the L & R inputs go to the REAR L & R channels
of the amplifier. In the right (FRONT L-R) position, the inputs are derived from the
FRONT channels and sent to the REAR L & R channels of the amplifier.
SUBWOOFER RCA Inputs
RCA cables marked “subwoofer” from head unit or other line level device
should be connected here. Use both inputs (L & R) for dual subwoofer output
from head unit. Use left (L) input only when single subwoofer output is to be
connected.
Lowpass Slope and Crossover Controls
Select appropriate crossover slope of 12 or 24dB/octave by moving
LOWPASS SLOPE switch. Lowpass crossover frequencies are
adjustable from 50Hz to 350Hz by rotary control.
SUBWOOFER Mode Switch
Move switch to left position (MONO L-R) when used with L & R subwoofer RCA
outputs. Move switch to middle position (L-MONO) when used with single sub-
woofer RCA outputs. Move switch to right position (NON-FADING MONO) when
subwoofer signal is to be derived from front and rear channels.
