With the growing popularity of the iPod and other small portable media devices there has to be a way to integrate those devices into your audio system. The cpa offers a flexible auxiliary input that makes adding those devices a snap. Many times the input level of the main source unit (CD player, stereo tuner, etc) is higher than the level of the iPod or other device. The cpa has a variable input adjustment for the auxiliary source so the output level can be perfectly matched to the main source units level.

The cpa isn't just for those needing to add another source to their vehicle. It is a preamplifer and line driver with master volume control. The cpa features a fully adjustable 7 band equalizer and variable low pass crossover with subwoofer level control. The illumination on the cpa is selectable between green and red.
