✔
modulation measured by the internal FM tuner
✔
MPX ITU BS412 power

3.5 AUDIO INPUTS
To access to the input set-
tings, click on the main menu
the option AUDIO INPUT.
Each input has the following controls:
3.5.1 GAIN
Adjusts the level of the input signal in a range of +/- 14
dB . For the analog inputs, the “zero” value corresponds
to the +4dBu level referred to -18 dBfs (AES K18). This
represents 18dB of headroom.
The input gain is adjusted so that 0VU peaks on the on-
air mixing console range from –22 to -9 dBfs on the pro-
cessor's input level meter.
3.5.2 TRIM R
Gain compensation for the right channel. It allows to fix
unbalances between channels, in a range of +/-3dB.
3.5.3 ST/MONO
Switch the input between STEREO or MONO (L+R) .
