Two Channels of API-style Compression for One Great Price!

The impressively versatile JDK Audio R22 compressor gives you two complete channels of API-style compression. In fact, the topology of the R22 compressor includes the same amazing compressor circuitry that API included in their legendary ATI Paragon mixing console, so you get the same classic compression style and sound you've heard on countless hit records. Each of the JDK Audio R22's channels includes the patented "THRUST" switch, which prevents high frequencies from being crushed out of existence, even when you need to dial in serious compression at higher ratios.

The R22 particularly shines when coupled with other vintage-American-style processors, such as the JDK R24 EQ. Its easy-to-use controls make dialing the right sound quick and simple, and custom VU metering (both for output levels and gain reduction) let you keep a close watch on your levels. You can use each of the R22's channels as completely separate single-channel compressors and link them together to compress stereo material, or sum them together via a true RMS summing circuit, which provides ultra smooth multiple level compression.
