PRACTICE SAFE SOUND™
Continuous exposure to sound pressure levels over 100dB may cause
permanent hearing loss. High power automotive sound systems can
generate sound pressure levels in excess of 130dB. When playing
your system at high levels, please use hearing protection and avoid
long term exposure.

AMPLIFIER SET TINGS
Signal Input and Output Configurations
The input section of the amplifier consists of gain controls, high pass
and low pass crossovers controls, Bass Boost control and RCA inputs
and outputs. The input section makes it easy to adapt this amplifier
to most system configurations.
Level Control
These Orion amplifiers have level adjustments to allow for easy
integration with any source unit. The input sensitivity can be
adjusted from 200mV to 8V. Refer to Testing the System and Adjusting the Sound of the System sections of this manual for detailed
instructions on setting the gain.
Line Output Configurations
The line outputs on Orion amplifiers offer easy system expansion and
can be used to route signal from the RCA line outputs to the next
Orion amplifier’s RCA line inputs in the signal chain.
Internal Crossover Configurations, Flat (full range)
The crossover section of the Orion XTR500.4, XTR750.4, XTR1000.4
XTR1700.4 and XTR2500.4 amplifiers are continuously variable
and extremely flexible.
When using Orion loudspeakers, minor deviations from the recommended frequency ranges can provide superior results depending on
your speaker locations and your vehicle acoustics. Setting crossoverfrequencies 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.
WARNING! DO NOT set crossover frequencies lower than the
speakers recommended operating range. This can cause driver
failure that is not covered by the manufacturer’s warranty.
Crossover Switch
Controls the type of filter for the onboard active crossover. The Orion
XTR500.4, XTR750.4, XTR1000.4, XTR1700.4 and XTR2500.4 have
a switch for the selectable crossover.
Full position does not attenuate any frequencies and is for full
range speaker systems.
High attenuates low frequencies and is used for mid-range speakers and tweeters.
Low attenuates high frequencies and is used for subwoofer
speakers.
Low-Pass Crossover
When the switch is to the center (FULL position), the low-pass crossover is bypassed. When the switch is to the center, the low-pass crossover is active. The low-pass crossover is continuously variable from
50Hz to 400Hz.
