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.

Because of the high impedance of the a/d/s/ input stage, the factory radio drives an easy load. This ensures lower distortion levels than if it was driving speakers or a Line Output Converter accessory. As a result, a high quality factory installed radio can deliver high quality sound that is nearly as good as the sound from a high-end aftermarket source unit. The speaker outputs of the factory radio are simply connected to a mini-DIN adapter as shown below. From this point on, the signal can be treated exactly as you would a preamp-level signal, except that the input level controls on the PowerPlate™ will be set to a lower than usual level when you make your final adjustments.

Conventional aftermarket sources may be connected using standard shielded RCA cables from the source unit’s preamp outputs to the PowerPlate™ inputs.

Note: When using 4 channels of input, be sure to configure the 2ch/4 ch input switch to 4ch input. Failure to do so may result in damage to the source unit.
