Switching off
To turn the transmitter off remove the Lemo plug, or put the
miniTX in sleep mode by switching it off using the SwitchiR.
Alternatively the miniTX can be turned off or on, even
through clothing, using the Control-X.
In sleep mode the orange LED will flash every two seconds
and the transmitter will draw very little current.
Connecting the audio input
• Connect the microphone or input cable to the four-pin
Lemo socket.
A positive microphone bias voltage is provided, enabling the
majority of modern lavalier microphones to be used with the
miniTX.
