HIGH LEVEL HARNESSES
Do not connect the high level input connections to power, signal, or chassis ground as damage
to the head-unit outputs may result . The high-level inputs are designed to work with either
grounded or BTL speaker level outputs (found on most head units) .
AMPLIFIER SETTINGS
Signal Input and Output Configurations
The input section of the amplifier consists of a phase switch that sets the output configuration,
gain controls, and RCA inputs . The input section makes it easy to adapt this amplifier to most
system configurations .
Input Gain
The Orion Cobalt CO500 . and CO800 . amplifiers have level adjustments to allow for easy
integration with any source unit . The input sensitivity can be adjusted from 200mV to 5V . Refer
to Testing the System and Adjusting the Sound of the System sections of this guide for detailed
instructions on setting the gain .
Phase Switches
0° - leaves output unaffected . The output signal is in phase with the input signal .
●
180° - inverts the output . The channel is 80° output of phase . This configuration is
●
useful for inverting the phase of subwoofers to improve staging in a vehicle . This is
also used when bridging two amplifiers into one speaker .
Auxiliary Output Configurations
The auxiliary outputs on Orion Cobalt amplifiers offer easy, unlimited system expansion . Routing
signal from a source unit, pre-amplifier, or equalizer is a matter of connecting RCAs to the RCA
Inputs and the RCA outputs to your next Orion Cobalt amplifier in the signal chain . 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 minimizes the potential
for system noise .
Internal Crossover
The crossover section of the Orion Cobalt CO500 . and CO800 . amplifiers is continuously vari-
able and extremely flexible .
When using Orion Cobalt loudspeakers, minor deviations from the recommended frequency
ranges can provide superior results depending on your speaker locations and your vehicle
acoustics . Setting crossover frequencies higher than recommended will not cause damage and
may provide superior sonic results depending on your system's performance goals . Refer to your
