Feed your amps the signal they deserve
AudioControl created the Matrix 6-channel line driver with one goal in mind to make your car audio system sound better. Many modern car stereos boast 4- and 5-volt preamp outputs, but they're rated at full output. Turn your stereo to a normal volume level, send the signal through a 20-foot cable, and your amps may end up with just a couple of volts. Enter the Matrix.
Get the most out of your system
The Matrix boosts the signal from your receiver up to 24 dB, right up to the maximum level accepted by your amplifier or processor. The high-voltage level keeps the noise out of your system, while feeding your amps the signal they need to deliver top performance. The Matrix is designed with three sets of inputs and outputs for the traditional front/rear/subwoofer setup, but it can also handle three separate 2-channel source units if desired.
Once connected, the Matrix makes it easy turn up the gain knobs until the lights indicate the proper output, and you're all set. The overload light lets you know if you need to back off on the gain. Balanced inputs reject noise caused by your vehicle's electrical system, but you can switch to unbalanced operation if necessary. The Matrix's low-impedance output keeps your signal going strong through long cable runs.
