|I found some nice
extruded aluminum boxes at the local surplus outlet (www.wackywillys.com).
I fabricated the top and bottom panels and the brackets to hold them
together. See the mechanical drawings page

|Top: To the
left is the volume control. Then the switch which is momentary in one
position (for the "call" function), and fixed in the other
direction (for mic mute). Below it is the Signal indicator.
Next, the two 1/8-inch jacks accommodate cheap computer-style headsets, and the 4-pin XLR connector accommodates standard Clear-Com wired headsets.
|Bottom: To the left are the loop-through 3-pin XLR connectors for the intercom line. The 1/8-inch jack is an external connection for the "call" indicator. This is used for cameras which do not have tally lights.|
