The dbx 266xs is a two channel compressor/gate that features OverEasy® compression technology along with an intuitive interface. The 266xs provides transparent, musical dynamic control for live sound and recording applications. Available in stereo or dual mono modes, the 266xs features quality XLR and 1/4" TRS inputs and outputs and True RMS Power Summing™. Gain reduction metering and LED indicators offer visual feedback for precision setting of threshold, gain reduction and gate.
Classic OverEasy® Compression
dbx's OverEasy® compression algorithm provides smooth, natural sounding gain reduction that is nearly inaudible. OverEasy® compression allows you to transparently smooth out uneven levels and add sustain and fullness to the mix with clarity. The 266xs's OverEasy® compression, combined with its musical AutoDynamic™ attack and release controls, makes it easy to achieve polished, professional results.
Tight Gate for Maximum Clarity
In addition to compression, the 266xs incorporates dbx's proprietary AutoDynamic™ attack/release controls, one on each channel. Adjust the attack and release speed to adjust the compressor's reaction to the incoming sound. The attack/release works in tandem with the compressor to create a very clean signal path.
Flexible Controls
With threshold, ratio, attack and release controls, the 266xs offers flexibility for any compression application. Threshold and ratio controls allow you to precisely set the amount of gain reduction, from subtle evening to heavy compression. Attack and release knobs let you tailor the speed at which compression is applied and released, enabling natural or aggressive compression based on your needs. LED gain reduction meters provide visual monitoring of levels to ensure optimal settings.
Road Ready
With a rugged metal construction and durable jacks and switches, the 266xs is built to withstand the rigors of live sound. Its compact, 1U rack mountable design makes it ideal for any touring or installed sound system. Ultra low power consumption and optional rack mount kits add to its live sound capability.
