AudioControl Matrix Plus: 6-Channel High-Voltage Car Audio Line Driver | Boost to 9.5V RMS (13V Max)

Unlock Clearer Car Audio with Matrix Plus

AudioControl MATRIX PLUS is a purpose-built six‑channel line driver designed to elevate what your factory radio can send to amplifiers and subs. Instead of letting pre‑amp levels stall at low volumes, this device provides substantial gain (up to 24 dB) so downstream amps receive a stronger, cleaner signal. In real-world terms, you may experience tighter bass, more precise midrange, and better overall consistency as you navigate between sources and listening levels. The result is a more responsive and engaging listening experience without nagging distortion or level mismatches.

What makes MATRIX PLUS stand out

• Three balanced differential inputs and three low‑impedance outputs for flexible integration with your existing system.
• Six‑channel architecture capable of driving multiple amplifiers and subs, with internal linking to spread the signal efficiently in SPL installations.
• Subsonic protection with a programmable PFМ subsonic filter (18 dB/octave at 33 Hz) to keep bass tight and protect speakers.

Performance you can rely on

• High voltage output up to 13 V peak (9.5 V RMS) @ 14.4 V, ensuring ample headroom for downstream amps.
• Ultra‑low distortion (< 0.005% THD) and a strong signal‑to‑noise ratio (–110 dB) for clean, accurate sound across the range.
• Output gain adjustable up to +24 dB to match sources and keep levels consistent when switching between media or inputs.
• Onboard LED indicators signal when each channel is delivering near‑optimal voltage, helping setup at a glance.

Durability and ease of installation

• Conformal coating protects a rugged PCB from vibrations and the elements, ideal for under-dash or trunk installs.
• Selectable ground isolation options (common, ISO default, or 200 ohms) for flexibility in noise‑prone builds.
• Phoenix‑style plug terminal block enables straightforward connections and quick removal.
• Compact footprint (8.7" x 6.7" x 1.15"), weighing about 2.25 lb, to fit tight spaces without clutter.

Convenient control and future‑proofing

The optional dash remote input (ACR‑1) lets you adjust master volume or sub level from the front seats, adding convenience for in‑car tuning sessions. For larger audio systems, the MATRIX PLUS can link two inputs to drive all six outputs, with one output capable of supporting up to seven amplifiers, giving you substantial expansion potential without sacrificing signal integrity.

Whether you’re upgrading a daily driver or building a performance system, MATRIX PLUS offers a versatile, technically solid path to clearer, more controlled car audio without overhauling your entire setup.
