Note: The Elite Wired Microphone includes some active electronic
circuitry, and therefore requires Phantom Power to be provided
from the device the microphone is connected to. The Elite Wired
Microphone requires a phantom voltage between 12 and 48V DC,
with a draw of maximum 2mA.
Control Wire Connection
The Control wires will be connected with the GPIO ports of the DSP or other
technology that is controlling the mute status of the microphones. The control
wires are only used when external control is selected using the DIP switches.
Using external control, pressing the button on the microphone will pull the
switch out line to ground. The DSP (or other technology) needs to be
programmed to react to falling edge (e.g. mute toggle), or for the switch out line
to be “low” (e.g. push to talk).
The LED In line should be connected to a GPIO out port. The Elite wired
microphones provide red and green LEDs to differentiate the state of the
microphones. The LED color is controlled by the DIP switch setting and the
voltage provided on this line. See the table on the DIP switch settings for more
details.
