TOP PANEL CONTROLS
1. I I n n p p u u t t G G a a i i n n A A d d j j u u s s t t m m e e n n t t s s - Control
amplifier sensitivity and are used to
match the input level of the ampli-
fier to the output level of the signal
source.
2. C C r r o o s s s s o o v v e e r r S S e e l l e e c c t t i i o o n n S S w w i i t t c c h h -
Controls the type of filter for the on-
board active crossovers. FLAT does
not attenuate any frequencies and is
for full-range speaker systems. HPF
attenuates low frequencies and is
used for mid-range speakers and
tweeters. LPF attenuates high
frequencies and is used for
subwoofers.

6. S S u u b b I I n n p p u u t t S S w w i i t t c c h h - Controls where
the subwoofer section of the ampli-
fier gets its signal. If the SUB INPUT
switch is in the ON position the
subwoofer section of the amplifier
will get its signal internally summed
from the channels one through four
RCA jacks, and the SUB RCA jacks
do not need input. If in the OFF
position the SUB RCA jacks must
have input.
7. I I n n p p u u t t P P a a r r a a l l l l e e l l S S w w i i t t c c h h - Controls the
input signal to the indicated chan-
nels. If the 3+4 switch is ON, chan-
nels three and four will derive their
signal from channels one and two
RCA jacks and no input is needed. If
the 3+4 switch is OFF, channels
three and four RCA jacks must have
input.
