The sensitivity of the audio input is settable between "AF Gain"
(measured in dB) or "AF Level" (measured in dBu).
To help proper audio gain setting, an audio bar is supplied (with
maximum peak indicator) indicating the headroom to audio peak
(0 dB , nominal deviation 40KHz). Set the gain, with the maximum
input signal, avoiding the peak on the audio bar.
TRY TO SETUP TO HAVE A MAX PEAK HOLD BAR CLOSE TO -6dB.
Using quick gain setup buttons (<GAIN>), it is possible to enter
quickly in the audio gain menu. Note that the menu has a different
