More information:
With (the common North American) +24 dBu coarse range setting in place and 0 dB gain control, the
conversion will transform +24 dBu analog input to 0 dBFS digital signal. Gain control will allow adjustment
of this setting +/-10 dB in 0.5 dB increments (see section 8.5.5 for OSD control details). The user has to
be aware that the front-end analog amps will saturate (clip) at +27 dBu independently of adjustable fine
gain/attenuation stage and the ADC stage.
With "+18 dBu" coarse range setting in place and 0 dB gain control, the conversion will transform +18 dBu
analog input to 0 dBFS digital signal. Gain control will allow adjustment of this setting +/-10 dB in 0.5 dB
increments (see section 8.5.5 for OSD control details). The user has to be aware that the front-end analog
amps will saturate (clip) at +21 dBu independently of adjustable fine gain/attenuation stage and the ADC
stage.
