AudioControl Matrix Plus 6 Channel Pre-Amp Line Driver
Couldn't Load Pickup availability
The AudioControl Matrix Plus is a 6-channel pre-amp line driver delivering up to 9.5V RMS (13V peak) output with 24dB of gain. It is designed to boost weak head unit pre-amp outputs for systems with long RCA runs, multiple sources, or multiple amplifiers.
Key specifications
- Channels: 6 in / 6 out (3 pairs each)
- Input gain: 24dB
- Maximum output: 9.5V RMS / 13V peak
- Output gain: -12dB to +24dB
- Inputs: balanced differential, 20k ohm
- THD: 0.005%; signal to noise: >110dB
- Frequency response: 10Hz–100kHz ±1dB
- Remote level control: optional ACR-1
MATRIX PLUS: 6-Channel Line Driver with Optional Level Control
Many modern head units have low pre-amp outputs, particularly at normal listening volumes. Send that signal through a long RCA run and your amplifiers may receive very little audio signal, resulting in weak or noisy sound. The AudioControl Matrix Plus solves this with 24dB of gain, boosting pre-amp levels to as much as 9.5V RMS / 13V peak.
With multiple sources such as multimedia or video, the Matrix Plus level-matches differing volume outputs so switching between them is seamless. For SPL builds, the internal linking system allows two channels of input to drive all six outputs, and each output can drive up to seven amplifiers. If you need a simpler line out converter, AudioControl's LC7i is also worth considering.
The Matrix Plus includes an optional dash control input for remote control of pre-amp signal levels via the ACR-1 (sold separately), making it suitable as a master volume or subwoofer level controller.

About the AudioControl DM-810
From our tech experts at CEN
The AudioControl Matrix Plus (DM-810) is a 6-channel pre-amp line driver that boosts weak head unit pre-amp outputs to as much as 9.5V RMS (13V peak) using 24dB of gain. It accepts six channels of balanced differential input and delivers six low-impedance outputs, each capable of driving up to seven amplifiers. With 0.005% THD and a 110dB signal-to-noise ratio, the signal stays clean throughout.
Who it suits
The Matrix Plus suits builds running multiple amplifiers, long RCA runs, or multiple sources that need seamless level-matching. Its internal linking system allows two channels of input to drive all six outputs, making it particularly useful in SPL builds. For a remote subwoofer or master volume control, the optional AudioControl ACR-1 connects directly.
Our tech experts advise
The Matrix Plus measures 4.6″ wide by 7.1″ deep by 1.2″ high and weighs 0.6kg, so check your installation space before purchasing. The ACR-1 remote level control is sold separately and is not included in the box. Car audio installation is priced per vehicle — visit our Nottingham installation page for details.

Frequently Asked Questions
Q: What does the Matrix Plus line driver do?
A: It raises low pre-amp signal levels from the head unit with up to 24dB of gain, delivering as much as 9.5 volts RMS (13 volts peak) to your amplifiers. A stronger signal over long RCA runs means better signal to noise and fuller sound.
Q: How many amplifiers can the Matrix Plus drive?
A: It has six input and six output channels. With its internal linking, two input channels can drive all six outputs, and each output can drive up to seven amplifiers.
Q: Is a remote level control included with the Matrix Plus?
A: The remote is optional. The Matrix Plus accepts the AudioControl ACR-1 remote level control for master volume or subwoofer level, but the box contains the Matrix Plus, power connector, manual and warranty only.
Q: Can CEN fit this for me?
A: Yes. CEN offers professional installation from our Nottingham premises. Contact us to book an installation slot or ask for a fitting quote.
