The dbx 266XL is a professional dual-channel compressor, limiter, and gate engineered to deliver comprehensive dynamics processing in a single rack space for live sound, studio, and broadcast applications. Building on the legacy of classic dbx designs, this unit combines patented OverEasy soft-knee compression with AutoDynamic attack and release circuitry, ensuring smooth, musical gain reduction that avoids the abrupt pumping and breathing associated with lesser compressors. The 266XL provides intuitive, goof-proof operation that lets users easily smooth uneven levels, add sustain to guitars, fatten drums, or tighten up mixes with professional results.

The advanced gate section features program-dependent timing algorithms that produce ultra-smooth release characteristics, even with complex signals such as vocals or reverb decays, preventing the unnatural swallowing of transients or premature closure that plagues conventional gates. Separate precision LED displays for gain reduction, compression threshold, and gate threshold allow quick, accurate setup at a glance, while comprehensive connectivity includes balanced XLR and 1/4-inch TRS inputs and outputs with sidechain inserts for external processing. In Stereo couple mode with True RMS Power Summing, Channel 1 controls become master controls and Channel 2 follows precisely, ensuring rock-solid stereo imaging even with high amounts of compression. Housed in a rugged 1U steel chassis with an internal universal power supply, the dbx 266XL delivers legendary dbx performance and reliability at an accessible price point.
