Channel Linking:

 To link the Main input to Ch 2 and 3 outputs, 

move the main jumper to the (opposite) position to enable the linking 

function. Then move the jumpers for Ch 2 or 3 or both channels to the 
“Connected to Main” position. The “Connected to Main” LEDs will illui

-

minate when the three jumpers for each Ch 2 and/or Ch3 are set correctly. 

Please see video tutorials on our YouTube channel for more information.

Note:

 When removing and replacing chassis top be sure to align LED 

and knob holes.

Signal-To-Noise:  
An Up and Coming Rock Group?

Your systems signal-to-noise (S/N) ratio is the measurement between 

your audio signal level, which contains music, and your system’s noise 

floor, which contains hiss, pops, buzzes, and whines.  If you are listening 

to your buddies car audio systems and it has all of the above obnoxious 

sounds...even when the music is playing, we call that LOW signal-to-
noise. On the other hand if you have your volume control cranked up 
on quiet songs, and you hear almost ZERO background noise, that is 
considered a HIGH signal-to-noise ratio.  Most serious sound-off competi

-

tors have high signal-to-noise ratios (at least the ones that take home the 
trophies).

When you talk about signal-to-noise ratios, the higher the signal, the 

better. Since you really can’t reduce the noise floor, signal-to-noise ratio 

can be readily improved by raising the signal level with a component like 
the Matrix Plus.

Level Matching

Level Matching is about making sure you run just the right amount 

of signal into an audio component. Since all AudioControl products are 
capable of high-voltage input and output, it is important that you MATCH 

the input voltage of your components. Most crossovers and amplifiers can 
handle up to about 2 volts before they clip. AudioControl signal processors 
can all produce at least 7.5 volts RMS, and can accept anywhere from 5 to 
9 volts RMS. LED voltage indicators on many of our products (like this 

one!) make it a snap to set levels!
