RRCCAA IInnppuutt JJaacckkss --
Accepts line level
outputs from head units or signal
processors at voltages between
150mV and 4 volts.
2.
IInnppuutt GGaaiinn AAddjjuussttmmeenntt --
Controls
amplifier sensitivity and is used to
match the input level of the ampli-
fier to the output level of the signal
source.
3.
CCrroossssoovveerr FFrreeqquueennccyy AAddjjuussttmmeenntt --
Adjusts the crossover point for the
on-board active crossovers.
4.
CCrroossssoovveerr SSeelleeccttiioonn SSwwiittcchh --
Controls the type of filter for the on-
board active crossover. 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 speakers.

BBaassss EEQQ SSwwiittcchh
- Adds an additional
6 or 12 db of bass boost to the
speaker output (4600X 12 db
only).

SSttaattuuss LLEEDD
- Will light BLUE to indi-
cate the amplifier is on and oper-
ating normally, and will be RED if
the amplifier shuts down due to
short circuit, or overheating
detected by on-board protection
circuitry.
NNOOTTEE::
The 2300X and 4600X amplifiers require that
the system remote power be cycled off and on
again to restart the amplifier after a protection
shutdown.
The 1500X amplifier will cycle off and automati-
cally turn back on when the fault condition clears.
The amplifier should be inspected for proper venti-
lation clearance on all sides of the amplifier (2-
inches). The speaker wiring should be inspected
for any shorts.
NNOOTTEE::
The 1500X and 2300X amplifiers have one
combined Power/Protection (BLUE/RED) LED,
the 4600X amplifier has separate Power (BLUE)
and Protection (RED) LEDs.
