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, high pass and low pass cross- overs controls, Intelli-Q control, and RCA inputs. 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 inte- gration with any source unit. The input sensitivity is a push button adjustment, with the depressed (in) position giving you a range from 400mV to 8V while in the out position this range is 200mV to 4V. Refer to Testing the System and Adjusting the Sound of the System under Setup and Troubleshooting section of this guide for detailed instruc- tions on setting the gain.

Phase Switches

L0° - leaves output unaffected. The output signal is in phase with the input signal.

L180° - inverts the output. The channel is 180° output of phase. This configuration is useful for inverting the phase of subwoofers to improve staging in a vehicle.

Internal Crossover Configurations

The crossover section of the Orion HCCA25001, and HCCA50001 ampli- fiers is continuously variable and extremely flexible. In addition to the variable built-in low-pass filters, the high-pass crossover incorporates the Intelli-Q feature. This circuit is designed to optimize the perfor-

mance of Orion subwoofers in all types of enclosures.

When using Orion loudspeakers, minor deviations from the recom- mended 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 perfor- mance 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.

Low-Pass Crossover

When the Slope button is in the out position, the low-pass crossover is active with a 2nd order (12dB per octave) slope. When the button is in the depressed (in) position, the low-pass crossover is active with a 4th order (24dB per octave) slope. The low-pass crossover is continuously variable from 20Hz to 300Hz.

High-Pass Crossover

When the On/Off button is the out position, the high-pass crossover is bypassed. When the button is in the depressed (in) position, the high-pass crossover is active with a 2nd order (12dB per octave) slope. The high-pass crossover is continuously variable from 20Hz to 200Hz and is optimized for use as a subsonic filter. Additionally, boost can be added at the high-pass crossover frequency for improved bass output while still protecting the woofer from excessive excursion. The Intelli-Q adjustment allows up to 10 dB of boost at the selected crossover frequency.
