Installation Instructions

Connecting to the Camera

1. Once the camera is installed, locate the AUDIO OUT on your camera
2. Strip the jacket of the 22/2 cable revealing the red, black, and bare wires inside.
3. Cut away the bare wire and plastic surround the cable inside. Strip away a small piece of the red and black jackets revealing the bare copper wire.
4. Wire the black and ground to the - and the red to the + of the AUDIO OUT of phoenix or gate connector.

Mounting the Audio

1. Decide where the STM-1 will be located, knowing the MX393 mic will need to reach it.
2. Determine a suitable place to mount the RDL EZ-MCP1, ideally beneath the work station
3. Using a stud finder, determine the best location to route the 22/2 cable
4. Cut a hole into the drywall, large enough to fit a mud ring into it securely.

   

5. Using glow rods or fish tape, pass the 22/2 behind the wall routing to the STM-1

   Note: The wires of the XLR will wire to the +, -, and ground Input on the STM-1.

6. Secure a pass through plate to the mud ring mounted for the XLR just ran
7. Using anchors and screws, mount the compressor
8. Place the MX393. Plug the mic into the F-XLR tail into input of the compressor. Plug the line to the STM-1 into the output of the compressor.

   

9. Mount the STM-1 above the ceiling
10. Wire the red to the + and black to the ground power terminals on the STM-1.
11. Cut a length of 22/2 from the STM-1 to the camera. Strip the jacket on both ends. Cut away the bare wire and plastic surround the cable inside. Strip away a small piece of the red and black jackets revealing the bare copper wire.
12. A short piece of 22/2 cable will also be needed (approx. 1 inch).
13. Strip the jacket from the cable and remove all contents keeping only the red cable.
14. On both ends of the red cable, strip off a piece of the jacket. Connect one end of the 1 inch audio cable to the +PWR terminal and connect the other end into the +PHNTM terminal.
15. Run another length of 22/2 cable from the STM-1 to the Audio Out of the camera's phoenix or gate connector.
