Total Dynamic Control

With eight independent analog compressor/limiters and gates, the two-Rackspace ACP88 solves a host of problems. Each channel has a fully variable compressor with a sidechain loop, soft/hard-knee compression, and an Auto Attack feature that applies preset attack and release curves. The full-featured gate includes a gate-range switch and a sidechain/key insert loop. Each channel can be bypassed.

The ACP88 gives you total dynamics control for multi-tracking and live sound reinforcement. Eight compressor/limiters deliver transparent dynamics control. Eight full-featured gates seamlessly control unwanted noise and bleed-through. Control vocals, tame drums, protect speakers, tighten the low-end – all from just two rack spaces of powerful processing.
