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.
All initial adjustments on the MX401 are made at the factory. If after installing the unit higher or lower output
levels are desired, adjust outputs using trimpots as indicated.
