All Quicktrack products use a consistent ground scheme. The MXT-1 power supply provides the
necessary ground conductor. Power supplies without the 3rd conductor ground should not be used
with Quicktrack products.
CAUTION: Do not plug power supply into AC receptacle until the secondary conductors have been
attached to the Quicktrack module. Doing so may cause the power supply conductors to short and
damage the supply.
Installion steps for the Quicktrack modules are as follows;
1- Remove the cover screw (All modules except MX410) and cover.
2- Press down on the lower edge of the Quicktrack mounting extrusion until the lower edge of the
printed circuit assembly comes free.
3- Slip the printed circuit assembly out of the upper edge of the mounting extrusion.
4- Mount the Quicktrack mounting extrusion in an appropriate location, away from moisture, heat
sources, and AC fields.
5- Connect all audio connections to the barrier connector using double conductor shielded cables
designed for low level audio signals. Do not use multiple solid conductor cables.
6- Connect the 3 power supply conductors to the power supply connection points on the barrier
connector.
7- Plug the power supply into an AC receptacled.
8- Check for proper illumination of the LED power indicator.
9- Adjust all audio levels as necessary.
10- Mount the cover onto the Quicktrack module being careful not to over-tighten the mounting
screw.

The Model MX414 has one mic input, and one line input,
mixed to a common output. Both inputs have adjustable gain.
The line input gain range can be increased by 6dB by
removing push-on shunt at JP3.
JP2 applies 15 volt phantom power to the mic input.
VR4 Adjusts range of remote pot.
All inputs and the output are electronically balanced.
The output may be used in either a balanced or
unbalanced configuration. Requires low voltage AC power
(See MXT-1).
