You'll Want This Tube Channel Strip!

The dbx 676 tube channel strip gives you classic warmth and punch, plus everything you need to sculpt your tracks to perfection - right from the get-go! Over 40 years of dbx dynamics processing is packed into this 2U professional rackmount chassis. It all starts with an immaculate high-voltage, Class A tube preamp section running on 250 volts, delivering signal that can be as pristine or filthy as you desire. From there, the 676 gives you the compressor/limiter design from the acclaimed dbx 162SL, as well as a 3-band parametric equalizer with swept mids. At Sweetwater, we're mightily impressed with the dbx 676. We think you will be, too!

dbx 676 Tube Mic Preamp Channel Strip at a Glance:
  • From pristine clean to delightfully dirty
  • Exacting control over dynamics and tonal balance
  • Pro features, easy to use
From pristine clean to delightfully dirty

A vacuum tube-based channel strip that offers a bevy of flexible sound-tailoring options, the dbx 676 delivers stunning sound for recording and live sound applications. When you first fire it up, that glowing tube behind its front-panel grille is your first clue to what's in store: the sonic glories of a world-class vintage/modern design. dbx designed the 676 for rich, pristine sonics and tube warmth, and included a flexible gain structure that lets you add any amount of personality, punch, and edge to vocals and instruments. The 676 rocks a high-gain, Class A tube mic preamplifier section based around a 12AU7 vacuum tube that you can tweak for your desired degree of harmonic character, from pristine clean to delightfully dirty.

Exacting control over dynamics and tonal balance

For exacting control over dynamics and tonal balance, the 676 includes the compressor/limiter design from the acclaimed dbx 162SL, plus a 3-band parametric EQ. Featuring both soft- and hard-knee compression, proprietary AutoVelocity manual and OverEasy modes, and a PeakStop limiting algorithm - plus threshold, attack, gain and release, and auto attack and release controls, the compressor/limiter gives you amazingly flexible control over your dynamics. The 676's 3-band parametric EQ lets you adjust boost/cut and bandwidth at frequencies that were selected for maximum musicality.

Pro features, easy to use

The dbx 676 gives you professional connectivity, with 1/4-inch and XLR inputs and outputs, a front-panel instrument input, and a side-chain insert. The 676 lets you precisely tailor your input and output levels - which you can keep tabs on via a large, old-school multi-function VU meter. A front-panel tri-color indicator lets you know the status of the 676's optional digital output card. Although extensive in its capabilities, the dbx 676's vintage-style controls and VU metering make it delightfully quick and ease to use. And its military-grade build will give you rock-solid service for many, many years!

Underrated and well worth the price tag!!!

Extremely underrated, versatile tube channel strip. I love running mono synths through it, especially with sidechain compression enabled in electronic music productions. As for vocals, it's proven very flexible as well, on many styles - male or female. I've also used it with mics on cabs and when recording snares. The learning curve for gain staging is simple and once you understand it (which takes all of a few seconds) you won't be worrying about any noise issues. I start with the attenuation knob at around 9, then adjust the gain knob until clipping. I then dial the gain knob back until clipping stops and lastly adjust the attenuation knob to taste. I never have noise in my recordings and you won't either. You will have a nice recording that sits well in the mix and you can thank me for that later! Lastly, the stock tube sounds fine but you can swap it out for other tubes if desired. Do not sleep on this unit!

This is Awesome

I was somewhat skeptical at the beginning since I've never had any dbx gear in my studio and since i do a lot of voiceovers I needed a channel strip for my studio b. I took a chance, and I have no regrets.
As soon as I powered it up I was blown away by the warmth and quality this baby produced.
It's worth every penny. I strongly recommend it.

Not a Parametric EQ !!!

Please get the product description right folks!! This does not have a parametric EQ!! Each band is independently sweepable with a preset corner freq, and a switchable narrow / wide bandwidth. Thanks for changing the product description to reflect this!!
