This varies from product to product; for example, meters in Pro Tools are labeled directly in DBFS[1]. So are Yamaha digital mixers (at least the LS9 and M7 - not sure about the newer ones). On the other hand, the Allen & Heath GLD has its meters labeled differently, and I'm not quite sure what they're referenced to (they go up to +12). This can be a bit frustrating, since I never know how close I am to digital clipping, but in practice I aim to get everything around 0 dB on the meters and I have at least 12 dB of headroom. Wikipedia has a neat list[2] of different analog reference levels for 0 dBFS. 1: Pro Tools metering - http://i.imgur.com/YcUBR6H.png 2: https://en.wikipedia.org/wiki/DBFS#Analog_levels |
