Selectable Ground Isolation
Avoiding ground loops and grounding-related noises are of paramount
importance in any installation. For this reason we have provided a flexible
scheme of isolating signal grounds and power grounds.
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 speak
-
ers. 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.
Remote Level Control (optional)
You can purchase separately, the ACR-1 remote control to adjust vol

ume output from the comfort of the driver’s seat.
The Most Important Feature Of All: Reliability.
That’s right, your AudioControl Matrix Plus comes with a full 5 year
parts and labor warranty when it is installed by an authorized United
States AudioControl dealer. These seasoned pros have the training and the
equipment to take care of the job quickly and not leave your installation
looking like some of those things in the back of the refrigerator. Keep in
mind that if you, or your friends who are “good with electronics” choose
to install it yourselves, your Matrix Plus still has a 1-year parts and labor
warranty.

A GUIDED TOUR OF THE Matrix Plus
The Outside
1. Inputs:
The Matrix Plus will accept up to six channels of input
signal which means it will work with source units that have six channels
of output or it will accommodate three two-channel source units as in the
case of multi-media. All of the inputs utilize a balanced differential input
circuit, which can cancel noise that radiates into the signal path.
2. Linking to Outputs:
There is amazing flexibility with the Matrix
Plus for routing one input to one, two, or three outputs. These “Connected
to Main” LEDs light when the jumpers under the cover are set to route the
main input to outputs “Channel 2” and/or “Channel 3”. See page 7.
3. Level Control:
These cool little knobs can increase or decrease the
amount of signal sent downstream to your signal processors or amplifiers.
With this control you can get up to 24 dB of gain(13 volts peak) or 12 dB
of cut to maximize the amount of signal sent to your signal processors
or amplifiers inputs. Before you start to crank them all of the way up,
remember this: Most amplifiers can’t handle input voltages over 3 volts
without clipping. If in doubt, check with the amplifier manufacturer.
4. Outputs:
The Matrix Plus has six channels of low impedance out-
put, which helps when you desire more output because you have too much
input. Huh? What we mean is each pair of outputs on your Matrix Plus
has the strength and ability to drive more than just one amplifier. In fact,
you can drive up to 7 amplifiers off of each pair of outputs, which means
you have the possibility of driving 21 stereo amplifiers or even 42 mono
amplifiers! Wow!
5. Power:
If you see this one lighted, pat yourself on the back for prop
-
erly connecting the power terminal.
6. Maximized:
When these lights flicker while music is playing, you’re
pushing the limit - nearing the redline - entering the danger zone. Try
backing off on the Gain Control until it stops flickering.
