Presonus ACP88 Compressor

Take a look - you get eight separate compressors (hard or soft knee) with full control of threshold, ratio (1:1 -20:1), attack, release, and gain. You also get eight gates with threshold, attack and release controls, your choice of balanced or unbalanced I/O, a sidechain jack on every channel for spectral compression and a separate jack for gate key processing. Improvements over the original ACP-8 include increased dynamic range, better gates, brighter LEDs for low light conditions, and a built-in power supply!

A unique linking function makes it possible for any channel to be linked to the previous! This comprehensive bus can link two to eight channels together in any order as well to create various link groups.

• Eight Full Featured Compressor/Limiters

• Balanced/Unbalanced I/O
• Comprehensive Linking via Unique Power Summing Bus
• Takes the Place of Multiple Processors
• Crystal Clear Compression & Gating for Multi-Tracking & Live Sound
• Allows Spectral Processing & Gate Keying via Separate Jacks
• +4/-10 Stereo Operating Level

Best-in-class audio.
With top-shelf components and classic analog design, it’s no surprise that the ACP88 delivers best-in-class audio quality. At the heart of the ACP88 is the highly respected THAT 4301s VCA. This VCA has unsurpassed dynamic range, extremely low distortion characteristics, and virtually no noise. Who says they don’t make signal processors like they used to? Nonsense!

A fully variable compressor with the works.
Each of the ACP88’s eight independent channels has 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 applies preprogrammed Attack and Release curves. In short, you get all the parameters and features you expect from a high-end compressor—and we’re just getting started.

Full-featured gates with sidechains.
Each channel of the ACP88 has a dynamic noise gate after the compressor/limiter that can be used to gate an entire drum kit, isolate an instrument, or separate a vocal from background noise. Each gate has 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—great for de-essing, ducking, frequency-dependent gating, and much more.

You can’t do this with most dynamics processors.
With eight independent dynamics processors in one unit, you can employ tricks that aren’t possible with lesser processors. In particular, the Channel Link feature lets you lock together as many channels as you wish, so that all processors follow the setting of the master processor. Since you can create multiple simultaneous link groups, you could link a stereo pair of channels plus a group of four processors and still have two unlinked channels for other applications.

Great old-school processors never get old.
A superb old-school processor, with physical knobs and switches for every parameter, shoehorned into two rackspaces, the ACP88 delivers a pure analog sound that will always be in style. So if you want a professional analog dynamics processor that is every bit as powerful and sonically pleasing as the famous vintage processors were “back when,” go to your favorite PreSonus dealer and check out the ACP88. Because great sound never gets old.
