6.3.3.2. Input Level
The Input Level menu allows to check the input signal level of the corresponding
channel. It displays the level at the input stage of the signal chain. IA 202D and IA 402D
amplifiers are capable of input levels up to +20 dBu.
Figure 14. Channel Input Level Menu.
T menu displays input level in dBFS scale after it has been converted in to digital
domain for DSP. When the level is equal to -24, -12, -6, -3 and -1 dBFS a corresponding level
threshold is displayed. To avoid input clipping set your levels depending on the program
material and leave the headroom of at least 6 dB for loudest peaks. Nominal input level shall
be around -12 dB.
When clipping occurs a ”CLP” text is displayed at the end of metering scale. Avoid this
high input levels on all means since it causes hard-clipping and causes severe signal distortion!
Be aware that to increase signal-to-noise ratio a professional line level signal (ref. +4
dBu) shall be used!
