  • One stereo input can drive all six outputs for SPL systems

Six-channel line driver for car audio

The Audiocontrol MATRIX PLUS is a six-channel line driver built to raise low factory pre-amp outputs to a level that aftermarket amplifiers can use effectively. It suits owners who hear weak sound after long cable runs and installers who need consistent signal strength across multiple amps.

Signal gain without added noise floor

The unit provides 24 dB of gain, lifting signals up to 9.5 volts RMS and 13 volts peak so amplifiers receive a clean, strong input even at modest head-unit volumes. This headroom prevents the hiss that occurs when amps are turned up to compensate for a weak source.

Flexible integration for multi-amp systems

Internal linking lets two input channels drive all six outputs, and each output can feed up to seven amplifiers for large-scale builds. An optional dash-mount control enables remote pre-amp level adjustment, while level-matching across sources keeps volume consistent when switching between media.

Questions about this item

How do I install the MATRIX PLUS line driver and what is the common wiring mistake?

Connect the source to the inputs, run up to 20-foot cables to the amplifiers, and set the gain to match 9.5 volts RMS. The step often missed is adjusting each channel's gain so the amplifier input does not clip.

What maintenance or replacement will the MATRIX PLUS need over time?

The solid-state line driver has no moving parts or consumable components. Periodically check that power and signal connections remain tight and free of corrosion for consistent 24 dB gain performance.

What limit appears first during extended high-output use?

The output stage clips if the signal exceeds 13 volts peak. With 24 dB of gain, sustained high-level input can reach this ceiling before thermal protection activates.
