Classic analog dynamics processing.

One of our 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, linkable, full-featured compressor/limiters and gates, each of which can operate at either +4 dBu or -10 dBV, the ACP88 can solve a host of thorny studio and live-sound problems. Each channel can be independently bypassed so you can audition signals with and without processing. And you can see at a glance what’s going on, thanks to a six-segment LED gain-reduction meter and pair of LEDs that indicate gate position (open/closed) and compression threshold (above/below).
