Description:

Bring a more professional sound to your mix

Adding a dbx® 266xs Compressor/Gate to your live sound rig or studio gives you more
dynamic control to help create a more polished, professional sound. Having compression in
your audio chain gives you the ability to smooth out uneven levels, add sustain to guitars and
fatten up your drums. It also makes it easy to bring vocals to the front of your mix - adding
greater clarity and making them stand out from the surrounding instruments.

dbx knows compressors...after all we invented them! The 266xs is the latest in a long line of the
world's most successful compressors from the inventors of the technology. Its patented
Overeasy® compression technology provides smooth and musical performance while the
AutoDynamic™ attack and release controls, found only on dbx compressors, puts great sound
within easy reach. The 266xs can operate in stereo or dual-mono modes, has true RMS power
summing and features quality XLR and 1/4" TRS inputs and outputs. It cuts no corners on
visual feedback with gain reduction metering and easy-to-read backlit switches.

Features:

Error proof operation to smooth uneven levels, add sustain to guitars, fatten drums or tighten
up mixes

New gate timing algorithms ensure the smoothest release characteristics

Program-adaptive expander/gates

Great sounding dynamics control for any type of program material

Separate precision LED displays for gain reduction, compression threshold and gate threshold
allow quick, accurate setup

Stereo or dual-mono operation

Balanced inputs and outputs on 1/4" TRS and XLR connectors

Side Chain insert

Classic dbx® "Auto" mode
