Input Gain

Setting 4 inverts the output of both the left and right channels. Both left and right gain controls are active. This configuration is useful for inverting one set of speakers like rear speakers in front/rear system to improve staging in a vehicle.

Setting 5 inverts the output of the left channel. The left channel is 180° out of phase from the right channel. Only the right gain control is active. This is the “MONO BRIDGED” output configuration. Right Phase control determines the phase of the output. When the Right Phase control is in the 0° position, the bridged output is in phase with the rest of the system.

Setting 6 inverts the output of the bridged output . The mono bridged input is 180° out of phase from the rest of the system. Only the right gain control is active. This is the “MONO BRIDGED” output configuration. Right Phase control determines the phase of the output. When the Right Phase control is in the 180° position, the bridged output is out of phase with the rest of the system.

HCCA amplifiers have separate left and right level adjustments. The input sensitivity of these adjustments range from 200mV up to 5Vrms to easily integrate with any source unit both after market and OEM (Original Equipment Manufacturer) Refer to the Testing the System and the Adjusting the Sound of the System for detailed instruc- tions on setting up the level controls.
