  • Page 15: Signal Sources

    signal sources Due to the wide input level adjustment range, all a/d/s/ PowerPlates™ can be driven with either a conventional preamplifier drive signal or the amplifier signal from a powered source unit. This makes the PowerPlate™ perfect for upgrading an OEM (Original Equipment Manufacturer) stereo system while retaining the factory installed radio.

  • Page 16: Internal Signal Routing

    internal signal routing 2-channel/4-channel input switch - routes RCA input from channels 1/2 to channels 3/4. When the switch is engaged, channel 1 input is routed to both amplifier channels 1 and 3 with input channel 2 routed to amplifier channels 2 and 4.

To use this feature, simply connect. the AC502 into the DIN connector on the PQ40.2, and install the AC502 in the desired location. To adjust the constant bass level, Locate the AC502 control switch on amplifier and push IN, or leave it OUT to control the level of channels 3/4.
  • Page 19 adjusting input sensitivity The input sensitivity setting is important to ensure proper performance, low noise levels, and maximum system reliability. As a general rule, components at the "front end" of the system should be set as high as possible with the input sensitivity of the amplifier set as low as possible while still providing adequate volume levels.
