AMPLIFIER SETTINGS

Signal Input and Output Configurations

Depending on your model, the input section of the amplifier consists of gain controls, high pass and low pass crossovers controls, Intelli-Bass control and RCA inputs and outputs. The input section makes it easy to adapt this amplifier to most system configurations.

Input Gain

These Orion amplifiers have level adjustments to allow for easy integration with any source unit. The input sensitivity can be adjusted from 150mV 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.

Line Output Configurations

The line outputs on Orion amplifiers offer easy system expansion. Routing signal from the RCA line outputs to the next Orion amplifier’s RCA line inputs in the signal chain.

Internal Crossover Configurations

The crossover section of Orion 2002 and 3002 amplifiers are continuously variable and extremely flexible. There are eight different crossover configurations possible allowing high-pass, low-pass, and band-pass operation. This circuit is designed to optimize the per- formance of subwoofers in all types of enclosures.

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 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.

WARNING! DO NOT set crossover frequencies lower than the speakers recommended operating range. This can cause driver failure that is not covered by manufac- turer's warranty.

Crossover Switch

Controls the type of filter for the onboard active crossover. The HP-4800 has two switches, the upper switch is for channels 1/2, the lower switch is for channels 3/4.

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 left (FULL position), the low-pass crossover is bypassed. When the switch is to the right (LOW position), the low-pass crossover is active. The low-pass crossover is continuously variable from 50Hz to 500Hz.
