The front crossover is high pass and can be adjusted from 20Hz to 5kHz by
turning the FRONT HP FREQ. control. If you need full-range, turn the control
fully counterclockwise to the 20Hz position. The rear crossover can be high
pass or low pass, chosen by the REAR HP/LP switch. The REAR XOVER
FREQ. control determines the rear crossover frequency between 20Hz and
5kHz, 20Hz being fully counterclockwise. The RCA outputs are always mono
low pass at 90Hz to send a subwoofer signal to another amplifier.
The front crossover is high pass and can be adjusted from 20Hz to 5kHz by
turning the FRONT HP FREQ. control. If you need full-range, turn the control
fully counterclockwise to the 20Hz position. The rear crossover actually
consists of two crossovers, one high pass and one mono low pass. The
high pass section is a 12dB/octave Linkwitz-Riley type that is adjustable
from 20Hz to 5kHz using the REAR HP FREQ. control. For full range
operation, turn the control fully counterclockwise to the 20Hz position. The
low pass section is a 24dB/octave Linkwitz-Riley type that you can adjust
from 44Hz to 315Hz with the REAR LP FREQ. control. High pass or low
pass to the rear channel is determined by the REAR HP/LP switch, 'OUT'
being low pass and 'IN' being high pass. When you select high pass, the
RCA outputs will be low pass and vice versa.
The front and rear crossovers are both high pass, and can be adjusted from
20Hz to 5kHz using the XOVER FREQ. FRONT and REAR controls. For full
range operation, turn the control fully counterclockwise to the 20Hz position.
The subwoofer crossover is a 24dB/octave Linkwitz-Riley type fixed at 90Hz.
