Mono Subwoofer Operation
If the amplifier is to be bridged and used with a subwoofer connected to the REAR channels, use the
“SPEAKER OUTPUT” terminals marked for mono use.
WARNING! Subwoofer impedance must not fall below 2 ohms when in MONO mode.
Installation—Fuses & Wiring (cont.)
1) Music
The material chosen for head unit/amplifier system setup must be both clear in recording quality and dynam-
ic in amplitude. Many audiophile “test” discs have musical tracks with both of these characteristics and should
be used.
2) FRONT & REAR Sensitivity Controls
Turn controls all the way counterclockwise (minimum position). In this position,
the amplifier will be less sensitive to the input signal from the head unit.
Setup Tuning—Full-range Speakers
FRONT crossover control
REAR crossover control
3) FRONT & REAR Crossover Controls
Crossovers should be turned off during this phase of set-up. Move the HIGHPASS and FILTER switches to
the “OFF” position—with these settings, full-range signal is sent to the FRONT & REAR speaker outputs.
