High-Pass Crossover
When the switch is to the right (OFF position), the high-pass crossover is bypassed. When
the switch is to the left (ON position), the high-pass crossover is active. The high-pass
crossover is continuously variable from 20Hz to 3kHz.
High-Pass Woofers
The high-pass crossover is continuously variable from 20Hz to 3kHz. The high-pass crossover
is now optimized for use as a subsonic filter for subwoofers. Additionally, boost can be
added for improved bass output while still protecting the woofer from excessive excursion.
Fine Tuning the Crossover Frequency
The crossover section is marked at four frequency points for ease of system adjustment.
These points are 20Hz, 250Hz, 1kHz, and 3kHz. Specific crossover points can be chosen
based on the recommended operational bandwidth of your speakers.
Auxiliary Output Configurations
The auxiliary outputs on Orion amplifiers offer easy, unlimited system expansion. Routing
signal from a source unit, pre-amplifier, or equalizer is a matter of connecting RCA's to the
RCA Inputs and the RCA outputs to the next Orion amplifier in the signal chain. When the
switch is in the COPY position, the RCA output is an identical copy of the input signal. The
signal passes through a buffer stage so that several amplifiers can be daisy chained without
signal loss or overloading of the source unit. This maximizes the signal output and mini-
mizes the potential for system noise.
When the switch is in the MASTER position, the RCA outputs are buffered through the gain
stage of the amplifier and filtered through the crossover sections of the amplifier. When set
this way, the amplifier's gain and crossover settings are sent to other amplifiers down the sig-
nal chain. This can be useful for configuring multiple subwoofer amplifiers easily in a large
SPL system. All subsequent amplifiers after the master amp will be in the COPY position and
have their gains set to zero and all crossovers turned off. The master amplifier will control
all the functions of the slave amps via the MASTER RCA output signal.
AMPLIFIER WIRING
Power Connections
● Orion 4002 Fuse Size: (2) 20 AMP ATC
● Orion 6002 Fuse Size: (1) 60 AMP MAXI
● Minimum 4 AWG power and ground cable is recommended for acceptable per-
formance.
● Fuse power wire prior to wire passing through panels or near sharp edges and less
than 18" from battery.
● Ground amplifier to a good chassis ground as close as possible to the amplifier.
● Add extra ground wire (minimum 4 AWG) between the negative terminal of the
battery and the chassis.
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 helps espe-
cially in newer vehicles, where the current delivery of the factory electrical system
was designed only to accommodate electronics supplied by the auto manufacturer.
