Description
The CoolAudio V571 is a compander noise reduction chip, but it contains two VCAs which can be used independently. It is a modern replacement for the SA571 and NE571. The chip is very useful to squeeze a bit of extra performance out of BBD-based circuits like delays, chorus, or flangers. It can also help reduce noise in PT2399-based delay circuits.

We can’t get hold of further stocks of this chip currently because CoolAudio don’t have any. If that changes and we’re able to get some, we’ll reintroduce it.
