There is a new feature which is the dBV audio level. The measurements and the display allow
to control the signal level coming from the sound system of the place. Poor sound in the loop
system often comes from a low signal level in the sound system. This input uses the latest mode
on the FSM and displays a specific level.
We recommend a level between -10dBV and 0dBV.
