Owner's Manual

7. 1, 2, & 5 Volt: These lights will tell you when the signal level is
at 1 volt, 2 volts or 5 volts. You'll most likely want at least the 2-volt
light to flicker, more if the rest of your components can handle it. Any
AudioControl component that you connect after the Matrix Plus Line
Driver won't mind the 5 volt light flickering. Go ahead. Light it up!
8. Power Connector: This convenient little connector allows you to
hook up all the power and turn-on wires for your Matrix Plus Line Driver
in the convenience of a well-lit area and then plug them in by feel all
at once in your trunk's cavernous darkness. Screws on top of the connec-
tor should face up. But if you put the plug in upside down, nothing will be
damaged, the Matrix Plus just will not power up.
9. Remote Level Control Input: Input for optional ACR-1 dash
mountable remote level control.

10. Balanced Input Selector: Located under the cover and behind the
Input connectors are jumpers that allow you to utilize or bypass the bal-
anced input circuitry. Although it is shipped in the balanced mode, which
is best, it may be necessary to change this depending upon the configura-
tion of the components you use. To change this, move the appropriate
jumper on the 3-pin header.
11. Ground Isolation Selector: This feature allows you to change
the power supply ground for different systems. When the Matrix
Plus is shipped from the factory, the selector is in the fully isolated
position(which is generally the best.) To change the settings, make sure
you turn the system off, carefully move the black jumper from the center
two pins(Isolated) and move it to either the right two pins(200 ohms) or the
left two pins(ground).
