Audio Reference Levels

The specifications for the audio source devices may be listed in one of several units.

You may wish to use a sine wave generator such as the Extron VTG 300 as a source

for setting up audio inputs before the input devices are available. The tables below

are a convenient reference for equivalences between dBV, voltage, and dBu.
