Audio Metering
The meter has a slightly wider band to show the position of -18dBFS. Each of the pips
are 4dB apart so the meter will show from -38dBFS to -6dBFS accurately. The meter
is active at all times except when setting up the unit.
Display
The display normally shows the text On-Air, microphone settings and metering.
When a talkback button is pressed the unit will display whichever key is pressed (or
both). If a mute key has been programmed then the display will flash ‘Mic Muted’.
