PreSonus ACP22 Stereo Compressor/Limiter

The PreSonus ACP22 dual channel compressor/limiter/gate was awarded the 1999 Electronic Musician "Editors Choice Award" in the January 1999 issue of Electronic Musician magazine. The ACP-22 was chosen in the Dynamics Processor category.

"If you're looking for the largest amount of dynamics control for the least amount of money, look no further than the PreSonus ACP22." Said the EM staff.

The ACP-22 is a 2-channel dynamics processor designed to provide compression, limiting, and noise gating in a variety of applications, such as multi-track recording, live sound reinforcement and broadcast, and permanent sound installations. In any application, the ACP-22 provides 2 channels of crystal clear compression with full control over compression threshold, ratio from 1:1 to infinity:1, variable attack and release times, and switchable hard/soft knee. An auto mode takes the worry out of setting the compressor by offering program dependent attack and release times. A link button allows for the true stereo link operation. The ACP22 has onboard metering for gain reduction as well as input/output meters. Independent LEDs show soft/hard knee, auto in/out, and channel bypass positions. De-essing, ducking, and other forms of spectral processing can be accomplished using the sidechain provided on both channels.

The Noise Gates on the ACP22 are unparalleled by giving control over threshold, variable attack and release, and switchable gate range (-60db/-6db). The ACP22 also has a unique Lo Pass… read more Gate Filter that eliminates cymbals and other higher frequency range instruments from opening up drum and/or vocal gates — without effecting the audio output. Independent Gate Key Side Chain is included for external triggering and sprecise filtering. LEDs on the gate show gate position open or closed and gate range (-60db/-6db).

Inputs and outputs on the ACP-22 are either XLR Balanced or 1/4 in. TS Unbalanced. Each channel operates at +4dBu or -10dBV, selected via rear panel switch. The ACP22 is housed in a one-rack space, all-steel chassis. In keeping with the PreSonus "no wall wart" tradition, an internal power supply with voltage (for International use) is standard. read less
