1. IInnppuutt GGaaiinn AAddjjuussttm
meenntt - Controls
amplifier sensitivity and is used to
match the input level of the amplifier
to the output level of the signal
source.
2. CCrroossssoovveerr SSeelleeccttiioonn SSw
wiittcchh -
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. CCrroossssoovveerr FFrreeqquueennccyy AAddjjuussttm
meenntt -
Adjusts the crossover point for the
on-board active crossovers.
4. BBaassss EEQQ SSw
wiittcchh - Adds 8 db of addi-
tional boost to channels five and six
output when active.
5. IInnppuutt PPaarraalllleell SSw
wiittcchh - 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.
