Used Behringer Composer Pro-XL MDX2600 in great cosmetic and technical condition. Standard minor rack-ear mounting wear from standard rack placement. All potentiometers, switches, LED meters, and rear XLR / 1/4" TRS jacks are clean and 100% operational. 

Testing: Bench-tested. Verified compression gain reduction, expander/gate response, IGC peak limiting, tube simulation, stereo coupling, and audio passthrough on both channels.  

Pulled directly from a professional, climate-controlled, smoke-free corporate broadcast facility. All units have been tested, factory reset, and are running stable firmware. Expect minor cosmetic rack-wear/scuffs on the outer casing, but front panels and technical functionality are excellent.

Key Features & Specifications  

• IKA (Interactive Knee Adaptation): Program-adaptive compression circuitry combines the advantages of hard-knee and soft-knee characteristics for transparent dynamic smoothing.  
• IGC (Interactive Gain Control) Peak Limiter: Combines clipper and program limiter for reliable, distortion-free protection against signal peaks.  
• IRC (Interactive Ratio Control) Expander/Gate: Virtually inaudible noise suppression during quiet passages without clipping initial transients.  
• Switchable Tube Simulation: Adds adjustable second-harmonic warmth and character to digital signals.  
• Dynamic Enhancer & De-Esser: Built-in switchable enhancer compensates for high-frequency attenuation during heavy compression, plus integrated de-esser for removing sibilance. 
• Stereo Couple Mode: Selectable stereo link function with independent key input and sidechain listening options. 
• Precision Metering: 12-segment LED meters for Input/Output levels and Gain Reduction.
