CM1A Resolution Awards 2009

Winner! 

We are proud to announce, that the

RM8/CM 1A has won the Dynamic category in the Resolution Awards 2009.

The RM8/CM1A has been awarded this accolade by the readers of Resolution magazine

 

RESOLUTION AWARDS 2009



The result of requests from readers and manufacturers to 'rubber stamp' equipment to differentiate it and to credit excellence where it is due, Resolution Awards 2009 celebrate 'Quality and Innovation' in professional equipment shipped in 2008 and will be presented in elven product categories.

CM1A. Optical, Tube amplified Compressor

CM1A Description

CM1A is the Modular CL1B, with updated action!

 

The TUBE-TECH CM 1A Compressor is an optical, all-tube compressor.

It features exactly the same tube circuit as our famous CL 1B Opto Compressor, but the action is different due to a different, carefully selected optical element and a fine-tuning of the control circuit.


This provides the CM 1A with an attack that enhances transients in a more punchy way, making it ideal for percussive material, yet still very well suited for vocals, bass guitar, etc.

 

The different optical element does NOT seriously change the the "classic" characteristics, known from the CL1B

The action of the CM1A places it somewhere between the LCA2B (Tube VCA) and the classic CL1B.

CM1A has been extremely well received by numerous top engineers.

 

Note: Due to the high quality of the TUBE-TECH RM Series power supply and the pristine audio circuits, the Modular Series products deliver exactly the same uncompromised sound quality as our 19” units.

CM1A Technical Description

 

The TUBE-TECH CM 1A Compressor 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.
