AudioControl Store

For over two decades, AudioControl has been designing and manufacturing award-winning autosound products at our factory located in the rainforests of the Pacific Northwest. During this period, countless sound-off winning contestants have chosen AudioControl products to give them the competitive edge. "Can you really win without AudioControl", was part of an article written commenting on competition winning systems. Nothing sounds better than an awesome recording played back on a kickbutt system. Unfortunately, the acoustics of your vehicle can take away from your systems performance. While AudioControl products do not change the laws of physics (although they act like they do), autosound enthusiasts have long known that AudioControl products "make good stereo sound better".

MATRIX PLUS - 6 Channel Line Driver

AudioControl created the MATRIX PLUS six channel line driver with one goal in mind, to make your car audio system sound better. Modern car stereos boast many features but in many cases rather low pre-amp outputs, especially at low levels. Turn your stereo to a normal volume level, send the signal through a 20-foot cable, and your amps may end up with very little audio signal resulting in weak sound.

Equipped with 24 dB of gain, which can increase pre-amp signal levels up to 9.5 volts RMS/13 volts peak, the MATRIX PLUS line driver will transform your audio system. When integrating multi-media and video games or for driving dozens of amplifiers the MATRIX PLUS line driver gives your system a boost. With multiple sources, like video, the MATRIX PLUS level matches the different volume levels so switching between them is seamless. For SPL vehicles, the internal linking system of the Matrix means that two channels of input can drive all six outputs and each output can drive up to seven amplifiers.

The MATRIX PLUS line driver features an optional dash control input which facilitates remote control of pre-amp signal levels. This makes the MATRIX PLUS line driver an ideal controller for overall system master volume or subwoofer levels.

Key Features:

High-Voltage Line Driver:

The Matrix Plus is a pre-amp line driver that takes the input signal from up to three source units, increases it (up to 13 volts peak) and then delivers it downstream. No more low signal output voltages to allow noise into the rest of your performance car audio system.

Programmable Frequency Match (PFM) Subsonic Filter:

Many car audio systems truly push the limits of their subwoofer... without really knowing it. Tuned enclosures affect the roll-off of many speakers, yet lots of source material force the speakers to play lower than expected. The net result is wasted amplifier power and damaged speakers. The AudioControl PFM (Programmable Frequency Match) filter is a programmable subsonic filter. It allows you to only let the speaker play as low as it should be playing. Because every system is different, we allow you to change the PFM roll-off frequency to whatever you choose.

Six Channel Inputs & Outputs:

The Matrix Plus was designed for ultimate pre-amp flexibility. With that in mind we have provided six channels for input and six for output! For even more flexibility, the Matrix Plus inputs can be linked internally whereby one input channel can feed one, two, or three output channels.

Anti-Oscillation Output Circuitry:

Driving long lengths of cable can present a nasty capacitive load to the source that has to drive them. This capacitance can cause instabilities, which can lead to oscillations, radio interference and excessive system hiss. The Matrix Plus' low-impedance, high-current output circuitry easily handles long cable runs without their associated problems.

Balanced Inputs:

The Matrix Plus features balanced differential input circuit that rejects noise that radiates into the signal path between the source unit and your Matrix Plus. Even better, this circuit uses standard RCA connectors.

Line Driver Specifications

Signal Boost/Cut
The available signal boost or cut for each of the frequency bands.
12 dB
Max Output Level
The maximum level (in volts) of signal output. A higher level will increase the clarity and boost your signal.
Speaker Level Inputs
Speaker level inputs are commonly referred to as high-level inputs and vice versa. This input type allows you to get your audio signal directly from the speaker wire in your vehicle, instead of using RCA cables. The advantage of this is factory integration, as most stock radios do not have RCA outputs to run amplifiers.
Total Number of Inputs
This is the total number of input connections that go into the unit.
Total Number of Outputs
This is the total number of output connections that the unit will produce.
Frequency Response
The range of frequencies the speaker will reproduce (lowest frequency to the highest). Bigger is better, meaning the wider the range, the better. The optimal range is 20 - 20,000 Hz (which is the range of human hearing).
10 - 100000 Hz
THD (Total Harmonic Distortion)
The amount of change in harmonic content of the signal as it is amplified. A lower figure indicates less change and a more accurate amp. THD below 0.10% is inaudible.
Signal-to-Noise Ratio
This spec compares the strength of the signal to the level of background noise. A higher value indicates less background noise.
110 dB
The width of the item from left to right (side-to-side) measured in inches.
The height of the item, measured from top to bottom, in inches.
The front-to-rear depth of the item, in inches. If the item is angled or slanted, this value is the bottom measurement.

Great Product, to overcome low head unit output and noise

September 17, 2013

I bought this overcome the low 2v output of my high end (or so I thought) of my Pioneer Navi head unit that had terrible floor noise, and low output.

This unit allowed me to up the voltage by 24db (roughly to 13v) though I backed it off to about 5v, which helped me get better full range, less noise, and stronger audio levels that I could then equalize and amplify.

Highly recommended for ANY system

It was on close out (or some kind of sale), I had been running an audio control cross-over with built in line driver only for the line driver, just simplifying.

Clean signal up very well.
David T on Aug 17, 2014
Audiocontrol reputation.
Michael C on Oct 22, 2014
my system has 3 amps, 1 amp for the subs, 1 amp for the front speakers, and 1 amp for the rear speakers, my head unit has only 1 rca output which I am running to the sub amp and daisy chaining the other 2 amps, would this line driver be compatible with my system?
john k on Nov 20, 2015
Best Answer: Yes it would be great for your system. You would want to link the inputs so you can use that 1 input and have 3 outputs. The instructions that come with the unit will tell you how. Here is a quick guide. Channel Linking: To link the Main input to Ch 2 and 3 outputs, move the main jumper to the (opposite) position to enable the linking function. Then move the jumpers for Ch 2 or 3 or both channels to the “Connected to Main” position. The “Connected to Main” LEDs will illui- minate when the three jumpers for each Ch 2 and/or Ch3 are set correctly. Please see video tutorials on our YouTube channel for more information.
