Remote Gain Operation
NOTE: Do not use the Remote Gain control when you have an expanded system installed
(see Line Ouput Configurations). The Slave amplifier(s) gain will not be controlled.
The remote gain port provides easy remote access to the internal gain structure of the HCCA
power amplifier. The HP-RB1 plugs into the amplifier via the 1/8" mini jack plug. The HP-RB1
can be installed in the front of the vehicle to control the amplifier gain level. The HP-RB1 can
be used as a bass level control when used on an amplifier dedicated to subwoofers.
AMPLIFIER WIRING
Power Connections for the HCCA-D1200, and HCCA-D2400
● Orion HCCA-D1200 Fuse Size: 2 x 30 AMP ATC.
● Orion HCCA-D2400 Fuse Size: 3 x 40 AMP ATC.
● Power connections accept up to 4 AWG wire.
● 4 AWG power and ground wire recommended for optimal performance.
● Connect 12V+ to the battery through fuse holder. This connection provides +12V
main power to the amplifier.
● Power wire must be fused no more than 18" from battery.
● Ground amplifier to a good chassis ground as close as possible to the amplifier.
● Connect REM terminal to remote turn-on lead from source unit. This connection
provides +12V power to turn-on the amplifier.
● Add extra ground wire between the negative terminal of the battery and the
chassis.
Power Connections for the HCCA-D5000
● Orion HCCA-D5000 Fuse Size: inline 250 AMP.
● Power connections accept up to 4 AWG wire.
● Dual 4 AWG power and ground wire required for proper performance.
● Connect 12V+ to the battery through power distribution and fuse holder. This
connection provides +12V main power to the amplifier.
● Power wires must be fused no more than 18" from battery.
● Terminate both grounds of the amplifier to a good chassis ground as close as pos-
sible to the amplifier.
● Connect REM terminal to remote turn-on lead from source unit. This connection
provides +12V power to turn-on the amplifier.
● Add an extra ground wire between the negative terminal of the battery and the
chassis. Either dual 4 AWG or single 1/0 AWG is recommended.
NOTE: The addition of a ground wire from the battery to the chassis of the vehicle
improves the ability of the battery to supply power to the amplifier. This is recom-
mended because the current delivery of the factory electrical system was designed
only to accommodate electronics supplied by the auto manufacturer.
WARNING! The Orion HCCA-D5000 has two separate four-gauge power and ground
inputs. Both pairs of connections must use 4 AWG power wire for proper
operation. Failure to do this may damage the amplifier and is not covered
under warranty. The HCCA-D5000 cannot be operated in a bridge or strapped
configuration, attempting to do so will damage the amplifier.
