That extra context only serves to confirm my confidence in my suggestion, which in the light of that information I would have given a confidence level of '5'.

Thank you very much for the answers so far.
Unfortunately, there's not much context to add, it's an audio mixer owner's manual, describing the buttons. Nothing more... Here's a last paragraph with the term "lobby".

Auxiliary Output Level Control
This knob adjusts the mixed auxiliary output levels of the mixer and has a control has a range of from cut-off to +10dB of gain above unity. This output is intended to feed foldback systems (artist/presenter monitor system), assisted hearing or lobby audio systems where a mix balance of other than the main Left - Center - Mono output is desired.

Thanks again!

To continue my reply to your response to my peer comment: there are enough clues in the source text (artist/speaker, assisted listening, alternate applications) to strongly imply this is a situation involving some kind of auditorium, and as such, the 'lobby' will always be some kind of public reception area, concourse, etc. I'd say they are trying to talk in very general terms, presumably marketing to a very wide range of venues, hence the rather non-committal language.
But as I said, the 'lobby' will be as distinct from the 'hall/auditorium' etc., so I don't believe 'salle' is appropriate here — especially as the term may well be needed elsewhere in the text.
I did try to cover these very points in my answer, explaining to Asker why more context would make it easier to find the right terms — without wanting to complicate things unduly by seeking to discuss every conceivable option!

Ici, "lobby" veut dire "hall", et "feed" semble être l'alimentation sonore, le flux que le système audio du hall doit jouer. Y a-t-il un terme consacré ?
