PreSonus ACP88 Eight Channel Compressor Limiter with Gate

One of the all-time most popular products, the ACP88 delivers the classic analog compression that helped establish PreSonus as a leading signal-processor manufacturer. With eight independent, full-featured compressor/limiters and gates, the ACP88 can solve a host of thorny studio and live-sound problems.

Each channel provides a fully variable compressor with a sidechain send and return to enable spectral processing and ducking. In addition to the usual attack, release, ratio, threshold, and makeup gain controls, each compressor offers selectable soft- or hard-knee compression and an Auto Attack feature that overrides the manual controls and applies preset attack and release curves. A six-segment LED meter displays the amount of gain reduction.

The compressor/limiter is followed by a full-featured gate with attack, release, and threshold controls; a gate-range switch, which determines the amount of level reduction that occurs when the gate closes; and a sidechain/key insert loop that enables the gate to be opened, or "keyed," in response to a modified version of the program signal or some other external source.
