ST.BY. When ready to transmit, switch to ON. The ST.BY position acts as a
“mute” that maintains the RF signal but turns off the audio.

This 4-pin Hirose connector [ ] is the microphone input. Azden produces a
number of lapel, head-worn and neck-worn microphones that are specically
suited for the 1201BT. In addition, other externally powered (5VDC) electret
condenser microphones can be used when they are properly wired with the
correct Hirose connector) pin #1 is for audio +, pin #2 is not used, pin #3 is for
bias voltage and pin #4 is ground). If you are using the 1201BT as a wireless
instrument transmitter the connections are somewhat different (pin #1 is not
used, pin #2 is audio +, pin #3 is for bias voltage and pin #4 is ground).
