Am i correct in saying that when the meter shows 0VU on an analog compressor in the digital world it would typically read -18db on a digital meter. On UAD's LA2A Compressor it gives me the option of setting the output level to either +4db or +10db and states a VU meter reading of 0 corresponds to an output level of +4db if set to +4 and +10db if set to +10.
So if i set it to +4 and get the meter to hover around the 0VU mark this gives me an output of +4 so in the digital world would be -14db and the same with +10 it would give me an output of +10 which would be -8db.
I read somewhere that -18db is the best level for recording into 24-bit digital audio systems, as it allows plenty of room for clean transients, if this is the case should i say ie, set the output to +4db and then aim to get the VU meter to hover around -4VU which would balance me up to 0VU and so would get an output level of roughly -18db in the digital world.
Apologies in advance if i have got totally confused with this,
