When designing the 7721, Chameleon’s engineers started with a clean sheet of paper and deeply evaluated the details associated with developing a bus compressor for the modern studio. Basing detection and voltage control on a voltage control amplifier (VCA) topology and designing a circuit that provides low noise and transparency the team created an acoustic “glue” that is capable of consistently delivering punch and loudness to the signal.

The 7721 provides a classic set of adjustable settings as well as controls only available on esoteric compressors, including:

Soft Knee / Hard Knee

Allows you to change between a softer arriving compression effect and a faster arriving, limiting type effect.

Peak / RMS

This control allows you to choose between the Peak and RMS detection schemes that are quite different. Peak detection engages the compressor by monitoring peak or instantaneous voltage signals. RMS engages by looking at the average energy in the signal and comparing it to the threshold setting. Very different modes of operation that provide great solutions for specific problems. The 7721 is your ideal option!

High Pass Filter

If you decide to use a Side Chain signal as the compression trigger signal, you can use the High Pass Filter to high the audio signal and avoid pumping effects.

Classic Controls

Threshold / Attack / Release / Ratio – Low ratios provide a nice starting place for master transparency, 4:1 provides more color and higher ratios for a tougher sound full of character. We like to use Attack and Release controls to respond to tempo and feel of a track.

Blend

This control allows you to blend, or mix, the original uncompressed signal with the compressed signal providing another tool you can use to obtain your desired objective.

VU Meter

Monitor Input, Outputs and Gain Reduction levels.
