Behringer T1952 Tube Composer

The Behringer Composer Pro has become the industry standard compressor for numerous applications. Today, you'll find stacks of Composer Pros in the racks of professional touring companies as well as in leading studios the world over. Now there's a device that combines the Composer's famous interactive concept with modern tube technology: the Tube Composer T1952.

Features
Interactive Tube version of "industry standard" compressor-expander-gate

Fully automatic and manual compression, expander/gate, clipper, and program limiter functions

Innovative Interactive Knee Adaption circuit gives you the best of Hard- and Soft-Knee compression in a single dynamic process

Patented "Ultra-Tube" circuitry warms up your signal without bringing in unwanted noise, hum, or hiss

"Warmth" control lets you dial in as much tube sound as your want

Tube Composer features Sovtek tubes, large backlit analog VU meters and a "Retro" design with polished chrome front panel and vintage look

Interactive Ratio Control Expander/Gate lets you make incredibly "natural" fades to silence and eliminates "chattering"

Dual-action Interactive Gain Control Peak Limiter circuit provides both instantaneous "brickwall" limiting and reduces overall output level to avoid distortion

"Intelligent" Auto and Manual Attack and Release compression

Switchable true Stereo or Dual Mono operation and switchable +4 dBu/-10 dBv operating levels for the widest variety of applications

Servo-balanced XLR and TRS inputs and outputs

Special relay-controlled hard bypass prevents accidental "thumps in the night" in case of accidental power-down
