a single blast attenuator per channel
a switch in / out which could be likened to a bypass channel

see a breath or eliminates all background noise. within reasonable limits of course. it does not shrink a sagit buzz recess.
but it is quite effective.

This old model worth much more than the recent. it dates back 80, or Beringher time trying to make things right before the cheap. an electronics firm who spends years without problem.
the firm changed much unfortunately, but there are some pearls of this kind is surprising.
Very effective. small downside though. If I were doing the tweaks over its compliance with homologation specs 2 channel "denoiser studio" would be welcome. (But it takes 4 to 8 channels). carrement bleuffant.
