INTERNAL CROSSOVER SECTION

The crossover section of the HCCA amplifier is continuously variable and ex- tremely flexible. There are eight different crossover configurations possible allow- ing high-pass, low-pass and band-pass configurations. New for ORION amplifiers is the INTELLi Q feature on the high-pass crossover. This circuit is designed to opti- mize the performance of ORION subwoofers in all types of enclosures.

When using ORION loudspeakers, minor deviations from the recommended frequency ranges can provide superior results depend- ing 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 manufacturer’s warranty.

LOW-PASS CROSSOVER

When the push button is in the “out” position, the low-pass crossover is bypassed.

When the push button is in the “in” position, the low-pass crossover is active. The low-pass crossover is continuously variable from 45 Hz to 5 kHz.
