Features

  • Compatible with most vehicles' OEM audio systems: Features three sets of balanced differential line-level inputs and three sets of low impedance line-level outputs for integration with your existing audio system.
  • 6-channel line driver: Boosts weak factory radio signals up to 13V peak (9.5V RMS) @ 20k ohms for downstream amplifiers, subwoofers, and processors. Maximum output voltage 13V peak (9.5V RMS) @ 14.4V.
  • Ultra-low distortion: Provides crisp, clean sound at <0.005% Total Harmonic Distortion (THD) with accurate reproduction across the entire audio spectrum (10Hz - 100kHz). Signal-to-noise ratio: -110dB.
  • Conformally coated printed circuit board (PCB): Resists vibrations and protects against the elements for long-lasting use.
  • Programmable frequency match (PFM) subsonic filter: Eliminates speaker damage and wasted amplifier power (18 dB/octave at 33Hz).
  • Variable stereo gain controls: Allows you to adjust the output signals up to +24dB.
  • Onboard LED voltage indicators: Alert you to optimal and maximized output voltages for each channel.
  • Selectable ground isolation: Choose from common, ISO (default) or 200 ohms for flexibility in a variety of applications where ground loop noise may be present. A Phoenix style plug terminal block makes connections and removal easy.
  • Optional dash remote: Control master volume and subwoofer output levels from the front seats (ACR-1 sold separately).
  • Compact size: Transform your audio system without taking up extra space (8.7" x 6.7" x 1.15", 2.25 lbs).

Description

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 have 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. Let the AudioControl’s MATRIX PLUS put your system into high gear.

  • Dont hesitate
Here's the review with the tweeters included: This thing completely transformed my stereo build. I'm running an Android "Tesla-style" head unit in my Tacoma X-Runner with a Sundown SALT 200.4 powering four Ciare 6.5s and two Hertz MP 28.3 tweeters, plus a Kicker LX3000.1 powering two Kicker SoloX 8s. I couldn't figure out why my system just wouldn't get loud. After a ton of research, testing, and troubleshooting, I discovered the RCA outputs from my head unit were extremely weak. After installing the Matrix, my system's overall output increased by roughly 30–35%. The difference was immediate. Everything plays louder, cleaner, and with much more authority. If you're running an Android-style head unit and your system seems underpowered even after tuning, don't overlook your RCA voltage. If you're debating whether to buy one, just do it. It's not cheap, but for me it was 100% worth every penny. ... show more

  • Audio control quality, out of control bass!
If you are looking to build a serious system for competitive use then you will want every competitive advantage you can get without sacrificing quality. Audio control only makes top notch components no matter what you need. The first component i ever owned from AC was a eqx series 2 back in 1995 and it did not disappoint. Nowadays everything has evolved into high tech, very high power systems where wattage is in kilowatts and the amplifiers that are putting out this power need a high quality, stable and regulated signal. The matrix plus will do exactly that and do it well. Using the lights on the unit to dial signal gain makes it much easier to set your gains. Although most probably don't have an oscilloscope i still use it on the outputs to make sure I have a clip and distortion free waveform = clean output. I used this before my dsp ultimately feeding 2 3kw amps powering 4 x 18s and just the addition of this took me from 150db to 158db. I couldn't believe the difference but now I'm sold and wouldn't build a comp system without one. If you are unsure if you need one, don't be. You will only regret not getting one sooner. ... show more

  • Quality product
I got this to boost the RCA voltage of my SJOYBRING head unit and I am very satisfied. I thought about going with something cheaper and I'm glad I didn't.

  • Excellent product
Wow big difference in sound my radio was only putting out .3 volts in rca but with this I was able to boost it over 7 volts

  • Works well
I’ve used these in multiple builds I’ve recently found that some amps don’t like too much extra current so be careful using this.

  • Not For Everyone. Removed mine after about 2 months
Not overly impressed. Been in the car audio field for more than 30 years and this was the first time using this product. Kept it installed for about two months before removing it. If you work on setting your gains and understanding the output of your head unit, this is really not needed. I would suggest if you are in a situation where your audio source has a very low voltage (1-2V) out and you wanted a higher voltage to your amps. Other than that, I see no reason to use this. I plan on selling mine. ... show more
