dbx’s traditional spot atop the pro audio industry continues with the introduction of its new “Silver
Series.” The inclusion of 2 vacuum tubes makes the 566 Vacuum Tube Compressor no ordinary
compressor. Of course, it’s loaded with all the features you’d expect from a compressor, including
custom designed analog VU meters that monitor tube level, gain reduction, or output levels. The 566
Vacuum Tube Compressor also has full sidechain functionality, including sidechain monitor, and our
unique Contour function, which allows low frequency material to pass through the threshold without
triggering unmusical compression effects. It also includes the dbx OverEasy® threshold characteristic,
and Auto attack and release. Line/Instrument and mic inputs make the 566 versatile enough to use with
virtually any source device. Add to this impressive list of standard features extras like a sidechain insert
loop, True RMS Power Summing™, and the new patent-pending PeakPlus™ limiting topology and you
have a compressor that strengthens dbx’s outstanding reputation.
The premium 12AU7 vacuum tubes are hand selected for ideal triode gain matching, distortion, micro-
phonics and drive characteristics. You get the best tube sound with the most versatility available today.
And with the optional dbx TYPE IV™ Conversion System output, you can translate the essence of tube
processing directly to the digital world, without leaving the box. The digital output offers the ability to
communicate in either AES/EBU or S/PDIF at 16, 20, or 24 bit word lengths. In addition, TYPE IV™
offers the ability to select noise shape algorithms and dither types that best suit your music and your
medium. The 566 also has all the rear panel versatility and connectivity that make it easy to setup and
patch into any system. Gold plated Neutrik® connectors for the audio ins and outs ensure solid connec-
tions and pristine sound every time. Separate 1/4" connectors for the sidechain sends and returns, as
well as +4/-10 operating level switching make it a snap to use.
