6.8 diamond - Auto Gain
Auto Gain is available for all mic sources. It can be used to set the analog (mic preamp) gain automatically.
The system works by measuring the incoming signal level over a period of 5 seconds. Using an average of that
measurement, it then sets the mic gain value automatically.
Please note:
The gain adjustment happens automatically and so it is best to enable Auto Gain before the channel goes on-air.
Otherwise, the signal may distort while Auto Gain finds the ideal level.
To use the system effectively you will need to ask the talent to speak into the microphone at their intended "on-air"
level.
Operation
The steps below describe how to use the Auto Gain
feature.
1.
Start by asking the talent to speak and then turn on Auto Gain for the Mic source.
The simplest method is to use the
AGn
soft key on the source's fader strip. Alternatively, you can put the Mic source into
access and enable
Auto Gain
from the Input page on the GUI.
In both cases, you must press and hold the button for more than one second.
2.
The
measurement now takes place and the Auto Gain value is
adjusted.
During this time, the
AGn
button flashes in yellow to indicate that automatic gain adjustment is in progress. If the channel is
turned
ON
, then you will hear the gain changing.
3.
After
5 seconds, the Auto Gain value is applied.
The
AGn
button turns off showing that the process is complete. The mic source is now ready for your talent to speak on-
air.
At any time, you can use the fader strip rotary control to adjust the
Mic
gain manually. If you do this while Auto
Gain is active, then the automatic gain adjustment is canceled.
