Operation - Orion HCCA3000.1DSPLX Manual

OPERATIONS
POWER & PROTECTION INDICATORS - Provide instant information on
status of amplif ier, including short-circuit and thermal overload alerts.
RCA INPUT - Accepts Low Level RCA lnputs(200mV-6V) form a head unit,
pre amplif ier, or equalizer.
RCA OUTPUT - Provides easy connection to additional amplif iers. Note that
some OEM stereo head units may sense the attached load and may turn off
their speaker outputs if expected load conditions aren't achieved.
POWER CONNECTION - The battery terminal (BATT) must be connected
directly to the positive terminal of the vehicle's battery to provide an
adequate voltage source and minimize noise. Connecting the battery
terminal lead to any other point (such as the fuse block) will reduce the
power output and may cause noise and distortion. Use only 10 gauge or
thicker wire for this lead and connect it to the terminal of the battery after all
other wiring is completed.(A fuse should be connected in-f ront of the battery
no longer then 18" f rom terminal ring to fuse, for safety precaution).
GROUND CONNECTION - The ground terminal (GND) connection is also
critical to the correct operation of the amplif ier. Use a wire of the same
gauge as the power connection (10 gauge or thicker) and connect it between
the ground terminal(GND) of the amplif ier and a metal part of the vehicle
close to the mounting location. (Ground wire should be no longer then 24"
f rom the amplif ier). This wire should be as short as possible and any paint or
rust at the grounding point should be scraped away to provide a clean metal
surface to which the end of the ground wire can be screwed or bolted down.
REMOTE TURN-ON CONNECTION - The amplif ier is turned on by applying
+12VDC to the remote turn-on terminal (REM). The wire lead to this terminal
should be connected to the "Auto-Antenna" or "Turn-On" lead f rom the car
stereo which will provide the +12V only when the car stereo is turned on
(some radio's need a relay to boost the turn-on signal). If the car stereo does
not provide an Auto-Antenna" lead, the remote turn-on lead may be wired
to an "Accessory" or "Radio"terminal in the car's fuse block. This will turn
the amplif ier on and off with the ignition key, regardless of whether the car
stereo is on or off. The remote turn-on lead does not carry large currents. So
18 gauge wire can be used for this application.
SPEAKER CONNECTIONS - Depending on the type and number of speakers
used with the amplif ier, wire them to the speaker terminals as per the
appropriate wiring diagram. For most applications 18 gauge wire should be
used for the speaker leads but in no case thinner than 18 gauge. For leads in
excess of 10 feet; 16 gauge is recommended. When wiring the speakers, pay
careful attention to the polarity of the terminals on the speakers and make
certain they correspond polarity of the corresponding terminals on the
amplif ier. Do not ground any speaker leads to the chassis of the vehicle.
