• While the broadcaster’s output connection

and ‘On-Air’ indicator control is a very simple

operation to perform, we suggest that unless

you are familiar with cable connections and

audio installations in general, that you have an

Audio/Electronics Technician perform this task

to assure optimum performance.

• The On-Air Indicator LED is switched either On

or Off by applying an open or closed circuit

across Pins 4 and 5 of the output connector.

• When ‘open circuit’ (no connections across Pins

4 and 5), the LED is active. If you do not wish to

switch the LED via a console or separate mute

button, then the LED will be active continuously

whenever the microphone has P48V (Phantom

Power) applied.

• Most professional consoles have switches

that provide both open circuit or short circuit

outputs. These are usually called ‘Channel On’

or ‘Channel Mute’ controls and actually mute

the audio signal as well as providing external

contacts. These external contacts are usually

used to mute audio monitors and switch On-Air

lights at the same time as microphones become

active. These contacts can also be used to

activate the broadcaster’s ‘On-Air’ indicator.

• Remember, the LED does not interfere with the

audio circuit, and has no other function than that

of an indicator. The microphone does not mute

itself! The indicator is simply that; an indicator of

the status of what another device is doing.
