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 - Controls
amplifier sensitivity and is used to
match the input level of the amplifier
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 typically used for
subwoofers.
3. O O u u t t p p u u t t C C r r o o s s s s o o v v e e r r F F r r e e q q u u e e n n c c y y A A d d j j u u s s t t -

Adjusts the crossover point for the
on-board active crossovers.
5. V V a a r r i i a a b b l l e e B B a a s s s s E E Q Q - Adds 0 to12db of
additional boost to channels five
and six output when active.
6. 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 channels.
If the 3+4 switch is ON, channels
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. If the
5+6 switch is ON, channels five and
six will derive their signals from chan-
nels one through four RCA jacks and
no input is needed. If the 5+6 switch
is OFF, channels five and six RCA
jacks must have input.
