Chameleon Labs 7721 Stereo VCA Compressor

Chameleon Labs 7721 Stereo VCA Compressor

Stereo VCA Compressor with Peak/RMS Detection, Side Chain Highpass Filter, Soft/Hard Knee Switch, Threshold, Attack, Release, and Ratio Controls, and Dry/Wet Blend Control

Bus Compression for Today's Hybrid Studio

In designing the 7721 Stereo VCA compressor, the engineers at Chameleon Labs began with a clean slate to develop a bus compressor for today's hybrid studio. Basing detection on a voltage control amplifier (VCA), and designing a circuit that provides low noise and transparency, the team created a device that does an excellent job of gluing your mixes together while delivering that elusive punch and perceived loudness that makes a mix blast out of the speakers.

Enhanced control set

The Chameleon Labs 7721 gives you an enhanced control set with all the classic settings in addition to controls usually found only on esoteric compressors. Soft/Hard Knee lets you switch between a gentler compression onset and a faster onset more akin to limiting. Peak/RMS Detection lets you switch between Peak and RMS detection schemes that behave quite differently. Peak detection engages compression by monitoring instantaneous peak voltage signals, while RMS looks at the average energy in the signal and compares it to the threshold setting. These are very different modes of operation that provide ideal solutions for specific problems.

If you are using a Side Chain signal as a compression trigger, you can tune the Highpass Filter to avoid pumping effects. Traditional Threshold, Attack, Release, and Ratio controls are provided, as well as a Dry/Wet Blend control that allows you to mix the original uncompressed signal with the compressed signal at output for instant parallel processing. Lastly, a VU Meter is provided with a switch to select between Left or Right Inputs, Left or Right Outputs, or Gain Reduction.
