ssuum
m LL//RR—left front and rear and
right front and rear channels are
summed.
ssuubb LL++RR—set the switch to this
position when using an additional
D1200 amplifier connected in
Parallel mode.
ssuubb 118800°°—set the switch to this
position when using an additional
D1200 amplifier connected in
External Bridge mode.
6. GGaaiinn -- controls amplifier sensitivity
and is used to match the input level
of the amplifier to the output level
of the signal source. (front and rear
on A1004 and D2205.)
7. BBaassss EEQQ -- allows 8dB additional
bass boost (A802 and A1004).
8. XX--OOvveerr HHPPFF,, FFllaatt,, LLPPFF -- the HPF
attenuates low frequencies and is
used with mid-range speakers and
tweeters. Full does not attenuate
any frequencies and is for full range
speaker systems. LPF attenuates
high frequencies and is used for
subwoofers.
9. XX--OOvveerr FFrreeqq -- adjusts the crossover
point (50-500Hz) for the on-board
active crossover.
10. RReem moottee -- optional accessory which

minated RED if the amplifier shuts
down due to short circuit, DC offset,
or overheating detected by on-
board protection circuitry.
14. LLEEDD//FFaann -- allows connection of an
ooppttiioonnaall LED light bar or ooppttiioonnaall
cooling fan for the amplifier.
15. LLPPFF -- sets high frequency limit of
subwoofer channel (D2205).
16. BBaassss EEQQ -- allows 8dB additional
base boost on sub channel
(D2205).
17. SSuubb IInnppuutt//LLiinnee OOuutt -- selects RCA
