The 266xs from dbx is a dual channel compressor/gate that when added to a live sound rig or studio, will deliver more polished, professional sound. The unit can function either as a stereo processor or in dual mono mode and features all the usual controls required for this kind of processor.

The unit provides the ability to smooth out uneven levels, add sustain to guitars and fatten up drums. It also makes it easy to bring vocals to the front of a mix. For simplified operation the Overeasy compression technology returns smooth and musical performance, while the exclusive AutoDynamic attack and release controls puts great sound within easy reach. The processor has true RMS power summing and features quality input and output connectors. Comprehensive visual feedback is provided by gain reduction metering and backlit switches.
