Tube-Tech CM 1A – No Longer Available

Modular, optical tube based compressor for use in RM8 or RM2 rack - based on CL1B
MFR# CM1A

Product Description

The Tube Tech CM 1A Compressor is an optical, all tube based compressor targeted at single-track recordings: It is equally suited for delicate vocal recordings, as well as critical instrument recordings such as lead guitar, drums, bass etc.

The CM 1A features a gain-reduction element, positioned immediately after the input transformer. It is controlled by the sidechain amplifier, which also contain the two time control circuits – one for fixed and one for variable Attack/Release. The two time-controllers can either be used separately or combined. This circuit contains semiconductor OP-amps for the entire control.

A tube-based push-pull amplifier follows the gain-reduction element with variable gain up to 30 dB. A dedicated Bus selector with three positions (Off, Link 1, Link 2) is used whenever you want to link several compressors together. Input and output transformers have a static-screen between the primary and secondary wirings. Input and Output is transformer balanced as well as fully floating.

Features:

  • Unique low distortion gain-reduction element
  • All tube-based push-pull amplifier
  • Multiple interconnection of several compressors via two busses
  • LED display for monitoring compression and output
  • Continuously variable attack and release time
  • Gain Range (off to +30 dB)
  • Variable Threshold (off to -30 dBu)
  • Frequency response @ -3 dB: 5 Hz to 25 kHz
  • Low noise: < -75 dBu @30 dB gain
  • Clickless bypass switch

Note: This module requires the Tube-Tech RM8 or RM2 Rack

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.
