Manufacturer's Description from JDK Audio
The JDK Audio R22 dual channel compressor features two channels of API's patented award winning compressor circuit in a rack mount unit with internal power supply. This is the same compressor circuit originally designed into all ATI Paragon mixing consoles. Each channel includes the patented 'THRUST' switch to protect the sensitive high frequency content of the audio signal even under the most vigorous of compression ratios. The perfect companion to your R20 mic-preamp and R24 EQ, the R22 compressor provides comprehensive easy-to-use control of the audio signal with custom VU metering of both output and gain reduction. The two channels can even be linked for use as a stereo compressor with true RMS power summing of the left and right signals.
Features:
- Patented THRUST circuit
- Variable Threshold, Ratio, and Make-up Gain controls
- Switchable metering of output level and gain reduction
- Above threshold LED indication
- Switchable Hard or Soft Knee compression
- Linkable for stereo operation with true RMS power summing
Fully balanced XLR and 1/4" inputs and outputs
About Manufacturer
JDK Audio is an entirely new brand developed and engineered by API, a company that has been around since the late 1960's. Originally called Arsenal Audio, they have permanently changed the name of this fabulous new range to JDK. And, while API had a stellar range of excellent audio products that are benchmarks of the recording world, we decided to embark on a product line that would allow our engineering team to develop some new ideas that have been floating around our engineering table for years. After all- we're a Technology company - its what drives us - its what inspires us. And some of the new technology available to us is pretty cool stuff - it just doesn't fit anywhere in the API product mix. So JDK audio was born out of desire to expand the creative options we have available at API - no boundaries - no restrictions
