  • Variable input and output
  • Peak limiting with or without level compression

The Electrodyne CA 700 Limiter/Compressor is a high quality gain reduction and peak limiting device for use with speech or music inputs.The availability of limiting only, or limiting in combination with compression, makes the CA 700 Limiter/Compressor an extremely versatile unit. An exclusive innovation permits fast attack time and the333 availability of fast release time with low distortion. This circuit contains an automatic low-frequency gate that increases release time as needed to prevent the gain reduction from tracking a low-frequency signal, yet retaining the fast release time desired for most applications.

A three-position de-essing circuit provides for automatically reducing sibilance (hissing) in speech, when compressing, without any apparentroll-off of high-frequency response. The CA 700 Limiter/Compressor is designed for use in 600/150 ohm systems, has a self-contained 24-Vdc 150-ma power supply.

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.
