Chameleon Labs 7721 Stereo VCA Compressor

Stereo compressor with VCA-based signal detection and super low noise, IC based input section
MFR# 7721

Product Description

When designing the Chameleon Labs 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.
  • 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.
  • 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.

Features:

  • Stereo compressor with VCA-based signal detection
  • Super low noise, IC based input section
  • Side chain input allows a separate source to be used as the compression trigger
  • IC based, ultra-low noise output stage
  • VU meter for Input / Output Level and Gain Reduction monitoring
  • Super low noise internal power supply
  • Selectable high pass filter
  • Threshold, Attack, Release and Ratio controls
  • Selectable detection type Peak or RMS
  • Selectable compression types: Soft or Hard Knee
  • Blend control allows you to mix the compressed audio signal with the original signal

I would like to thank VK for the wonderful sales assistance, service and prices. This was my first purchase with you and it won't be my last. I only wish I'd discovered you years ago!

I had two Grammy wins this year - Ray LaMontagne & Carolina Chocolate Drops. Both made with help from Vintage King!

In almost 20 years in Pro audio buying, never did I receive a unit so well packed and exactly as described. Works flawlessly. The whole process has been so smooth. I will never hesitate to do business with you guys in the future and will recommend you to everyone I know.

This was my first experience buying something from Vintage King (although I surf the "used" categories on the website frequently!), and, despite being on the other side of the world, I had absolutely no trouble and everything went very smoothly.
Phil T.
The speed of delivery exceeded my expectations! I was VERY pleased that my shipment arrived in time for a scheduled vocal tracking session. The packing insured that my order arrived safely. And the sales staff responded quickly to questions regarding the product.

My experience with Vintage King was excellent. The order was here fast considering it was out of stock. The sales person had SKB send it to me directly and I couldn't have been more pleased.
Michael D.
From the minute I placed my order I was kept well-informed through each step in your process. Even though I was buying a comparatively modest piece of gear, your attention to detail made me feel like I was purchasing a six-figure mixing desk.
