DBX 576 Vintage Vacuum Tube Mic/Line Preamp & Compressor, -3dB, 10Hz to 200kHz 1990s - Silver

Up For Your Consideration Is 1-DBX 576 Vintage Vacuum Tube Mic/Line Preamp & CompressorFrequency Response: 10 Hz to >200 kHz +0/-3.0 dB I was going through some of the equipment I’ve picked up over the years and came across this dbx 576. Since I’m starting to list some of my studio gear on eBay, here’s a Solid Tube Microphone Preamp, EQ and Compressor that I used many times back in the day. I always kept it at the top of my rack with nothing above it, these units didn't run a little warm because of there tubes. I never stacking other heat producing gear around them that can shorten it's life. I also never left it powered on for days at a time when it wasn’t being used. Because it’s been sitting unused for years, I went through the entire preamp thoroughly: Cleaning all the switches, trim pots, connectors and plugs. The units tested out in good working condition except for the 20db pad on the eq. When pushed, it doesn"t respond. I've included a 10 foot mic cable with a 20 db pad to take care of that if needed. Everything else works with no problems that I could find. Hand selected Premium 12AU7 vacuum tubes in path Mic or line/instrument inputs on the preamp. +4/-10 operation Drive control for a wide variety of great tube effects PeakPlusªlimiting control on both preamp and compressor 3-Band EQ with sweepable mid-frequency, wide / narrow Q and hardwire bypass on the preamp Complete sidechain, OverEasy¨, Auto, and Contour functions on the compressor Optional TYPE IVªConversion System outputs (NOT IINSTALLED) Separate 1/4" insert send and return on the preamp Custom designed analog VU meters monitor tube drive, insert level, gain reduction, or output levels For more than 25 years, dbx has been a leader in the audio industry with its compressors, mic preamps, and signal‑processing technology. The Silver Series continues that legacy, and the 576 Vacuum Tube Preamp/Compressor brings dbx’s engineering into the tube arena with a feature set that covers everything you’d want in a preamp/compressor combination. The 576 includes custom analog VU meters that can monitor tube level, insert path, gain reduction, or output level. The compressor section offers full sidechain functionality, including sidechain monitoring and the unique Contour feature, which lets low‑frequency content pass through the threshold without triggering harsh or unmusical compression. You also get dbx’s classic OverEasy® threshold characteristic and Auto attack and release modes. The preamp section provides +48V phantom power, a 20dB pad, phase invert, and a low‑cut filter. It also features a three‑band EQ with a sweepable mid and selectable mid‑Q, plus a hardwire EQ bypass. You can route the preamp directly into the compressor, use the insert loop, and take advantage of the patent‑pending PeakPlus® limiting topology. 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 IVªConversion 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 IVª offers the ability to select noise shape algorithms and dither types that best suit your music and your medium. The 576 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 connections and pristine sound every time. Separate 1/4" connectors for the insert sends and returns, as well as +4/-10 operating level switching make it easy to integrate into any studio setup.
