Conductor Color
Silver (non-insulated)

Wiring

The audio conductors on the microphone will connect to audio inputs on the Audia/Nexia like a typical microphone.
Note that each capsule on the microphone requires its own dedicated input, so the MX396 will use two or three inputs
per microphone (depending on whether the mic is a DUAL or TRI model). The LED and switch conductors will connect
to the Logic Box. The LED In (black) conductor connects to a logic output, and the Switch Contact (red) connects to a
logic input.
Each MX396 uses two I/O terminals on the Logic Box, meaning that a maximum of 10 MX396's can be connected to a
single Logic Box. The diagram below shows a typical wiring scheme for a single MX396. The wiring shown is for a TRI
model microphone, a DUAL model would omit the yellow and gray conductors.

DIP switches

DIP switch 3 should always be in the UP position to ensure that the mic is not locally muted when the mute switch is
pressed.
If DIP switch 1 is in the UP position, the mute switch will behave like a toggle switch. If DIP switch 1 is in the DOWN
position, the mute switch will behave like a momentary switch.

LED control

The LED ring will light up green when there is less than 1V across the black and silver conductors (i.e., logic output in
the low state), and it will light up red when there is 5V across the black and silver conductors (i.e., logic output in the
high state).

Once the device is physically connected to the Logic Box, you'll need to program it. See
