Our take on the AudioControl Matrix

by Charlie Pastorfield

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.

Simple operation

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.

Our Product Research Team

At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere. That's because we have our own in-house Product Research team — they open the box, verify contents, check the owner's manual, and record dimensions, features and specs. We stay on top of new products and technologies to help people make informed choices.


Line Driver: To achieve the best possible signal to noise ratio and dynamic range from your amplifier, a line driver can increase the head unit's output voltage up to 24 dB (maximum is 9.5 volts RMS/13 volts peak). The Matrix has three sets of inputs and three sets of outputs.

Input Gain: The input gains are adjustable up to +24 dB, allowing you to increase the head unit's line voltage to the top of your amp's input range; up to 9.5 volts RMS/13 volts peak. The three sets of outputs have individual gain controls.

Output Voltage Indicators: Each set of outputs has four LEDs to indicate the output voltage; 2 volts, 5 volts, 7.5 volts, and Maximized (9.5 volts).

Balanced Inputs: Using the balanced differential input circuit cancels noise picked up in the transmission line between the Matrix and the the source unit. The three sets of inputs can be individually set to balanced or unbalanced if needed.

Ground Isolation: The power supply ground is switchable, in case of ground loop noise. The factory position is fully isolated (typically the best choice), but can be changed to Ground or 200Ω.

Input Linking: The channel 1 and channel 2 outputs can be linked to the channel 3 input, useful if the source unit has only one or two pair of line outputs.

Subsonic Filter: The subsonic filter on the channel 3 outputs is 18 dB/octave at 33 Hz. If the channel 1 and channel 2 outputs are linked to the channel 3 input, the subsonic filter is applied to those outputs as well. The crossover point is governed by a replaceable chip, so it can be modified.

Terminal Block: The power/ground/remote terminal is removable; the wiring is attached to the block, then the block is plugged into the Matrix.

AudioControl Matrix

Written By D, Cpt, Ca on Thursday, April 07, 2011
Crutchfield Customer Review (What's this?)
I have it hooked up to a Pioneer AVH P4300DVD going to a Polk PA 500.4
which power a set of Polk MM5251 and Polk MM6501, also a Polk PA 1200.1
which power a pair of Polk MoMo 2124. Only had it in a week everything needs
to break in. I'm running streeet wires Z5 and there is no noise. I level matched
as the video suggested and the amps played with the gains all the way down,
but I turned them up to just below a quarter. eveything is darn clear but need to
break in to really test. I'll give it a four now and reserve the five until I can really
test it, it will probably get a five in the end. It does what it says.
