The PreSonus ACP88 is an all-analog dynamics unit that packs 8 channels of compression, limiting, and gating into a tidy 2U rackmount box. High-quality THAT Corp. VCAs are at the heart of each channel, providing fast, clean gain reduction with remarkably low distortion. These fully variably compressors are ready for any task, with selectable knee and an Auto Attack mode that will get you squared away more often than it won't. Sidechain inserts for each compressor and gate allow for frequency-dependent compression, ducking and keying, making the ACP88 even more versatile than the front panel shows. This box represents an amazing value and deserves a spot in the rack of every single front-of-house engineer and project studio owner.
