9.2 AIRLAB METERING
The Airlab is shipped with 4 VU meters. The 2 meters on the left always follow the main program material
and the 2 meters on the right side of the meter hood follow the CRM selectors.
NOTE:
The following levels should be used for a suitable sound pressure, for music, talk shows and
interviews etc.
Music: up to 0 dB
Speech: up to +3 dB
Telephone: up to +3 dB
A mild compression such as 2:1 with slow attack and a threshold of -6 dB to limiting around +8 dB will
improve the relationship between different broadcast materials.
NOTE:
These are average settings only, presentation of modern pop music will certainly require
alternative settings.
The levels of the Digital Outputs depend on the internal level trimmers on the Airlab Dig Module.
A factory default is set to: 0dBu = -9dBFF.
