Presonus ACP88

8 Channel Comp / Limiter / Gate

Order Code: ACP88
RRP: $1,882.34

When it was first released, ACP88 was one of the most quickly snapped up products in the hood. Of course, fast forward a dozen-or-so years and the proliferation of digital mixers with onboard dynamics has seen its popularity diminish somewhat.

What has most definitely not diminished though, is the performance. So if you're in need of a few comps for an analogue live rig - or perhaps a mobile recording system, here's the one. Just 2RU and totally chocked to the brim with goodness:

Eight full featured compressor/limiters, eight full featured gates, side chain and trigger inputs on every channel and comprehensive linking via unique power summing bus. Allows spectral processing & gate keying via separate jacks.
