Orion Car Audio HCCA10004, HCCA10002 owner manual Removing the TOP Cover

1.HIGH PASS - Adjusts the lower crossover frequency of the ampli- fier.

2.CROSSOVER SELECTION - ALL is the full range setting, LOW is the low pass setting and HIGH is the high pass setting.

3.SLOPE - Selects the crossover roll off between 12db and 24db per octave.

4.LOW PASS - Adjusts the upper crossover frequency of the ampli- fier.

5.FREQ - Adjusts the center frequency of the Intelli-Q between 20 and 200 Hz.

6.Q - Continuously adjusts the “Q” boost of the high-pass crossover from 0 to 10dB of boost.

7.ON/OFF - Turns the Intelli-Q on or off.

8.Infrasonic (Subsonic) Switch - When On cuts off extremely low bass frequencies (below the range of human hearing that speak- ers cannot effectively reproduce). The high pass filter is engaged when the infrasonic switch is On. This improves efficiency of the amplifier’s power supply, improves sound reproductive perfor- mance, and reduces chances of damaging the subwoofers.

9.GAIN RANGE - Selects the input sensitivity range to either High (for high power head units) or Low (for line level head units).

10.GAIN - Continuous adjustment for full power output.
