BRAND NEW AUDIOCONTROL MATRIX PLUS 6-CHANNEL LINE DRIVER COMES WITH 3 YEAR WARRANTY NOT RETURNED ~ NOT REFURBISHED ~ BRAND NEW FACTORY SEALED! Just like the Matrix Plus you love, only smaller AudioControl's Matrix Plus 6-channel line driver has long been one of our most popular signal-boosting solutions for amp owners who wanted more powerful sound from their slightly anemic systems. This iteration of the Matrix Plus offers the same outstanding performance, but it's now 30% smaller in size, so it takes up even less room in your ride. And its board is now conformal coated to help protect internal components from dirt, debris, and vibration. Feed your amps the signal they deserve AudioControl's Matrix Plus 6-channel line driver will ensure that your sound processors and power amplifiers receive strong, clean signals to perform their best. Many car receivers boast 4- and 5-volt preamp outputs, but that's at full power. Turn it down to a normal volume level, send the signal through fifteen feet of RCA cabling, and your amps may end up with just a couple of volts — not enough for good clean amplification. Enter the Matrix Plus. Boost that signal The Matrix Plus boosts the signal from your receiver up to 24 dB, right up to the maximum level accepted by your amplifier or processor. The high-voltage level keeps the noise out of your system, while feeding your amps the signal they need to deliver top performance. The Matrix Plus offers three sets of inputs and outputs for the traditional front/rear/sub setup, but it can also be used in different situations to boost the signals of up to three separate 2-channel source units — like aftermarket CD players, DVD/Blu-ray players, or gaming consoles — if needed. Level-setting with LED indicators AudioControl makes it easy: turn up the gain knobs until the lights indicate the output levels you want, and you're all set. Lights show you when you've achieved a 1-volt, a 2-volt, or a 5-volt RMS output. "Maximized" lights let you know that you're at top volume and may need to back off on the gain. Balanced inputs reject noise caused by your vehicle's electrical system, but you can switch to unbalanced operation if necessary. The optional dash-mounted ACR-1 wired remote allows you to conveniently adjust the volume while you're on the go. 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.
