Bring a more professional sound to your mix
Adding a dbx® 166xs Compressor/Limiter/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. To protect your expensive
amps and speakers the PeakStop® limiter provides an absolute ceiling for peak excursions or large transients that could
damage your equipment.
dbx knows compressors…after all we invented them! The 166xs 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 166xs can operate in stereo or dual-mono modes, has true RMS power summing and features
quality XLR and ¼” TRS inputs and outputs. It cuts no corners on visual feedback with gain reduction metering and
easy-to-read backlit switches.
