CCrroossssoovveerr SSeelleeccttiioonn SSwwiittcchh
-
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.

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.
