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 2 CH / 4 CH switch that sets the output configura-
tion, gain controls, and RCA inputs. The input section makes it easy to adapt this amplifier to
most system configurations.
Input Gain
The Orion Cobalt CO6004 amplifiers have level adjustments to allow for easy integration with
any source unit. The input sensitivity can be adjusted from 250mV 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.
Internal Crossover
The crossover section of the Orion Cobalt CO6004 amplifiers is continuously variable 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
loudspeaker owner's manual for assistance in choosing the proper crossover frequencies for
your system.
Low-Pass Crossover
The low-pass crossover is active with a 2nd order (12dB per octave) slope. The low-pass crossover
is continuously variable from 50Hz to 500Hz.
