Introduction

It began more than 35 years ago with the vision of a single man to create a better way to record audio, a vision that has continued into a new millennium. The late David Blackmer, universally considered the father of modern Compression, sought to improve the dynamic range of analog recordings using decibel expansion. This quest produced the decilinear VCA and RMS detector, which together have changed the sonic landscape and made possible many of our current audio technologies. In 1971, Mr. Blackmer founded dbx®, which has collectively produced over 35 patents that continue to forge and reshape the landscape in the Live Sound, Studio Recording, and Installed Sound professional audio markets. Our award-winning team of designers and engineers have embraced Mr. Blackmer's passion for audio purity with a vengeance, and continue to design and build the precise and accurate tools necessary for today's audio production. From our rock-solid Analog products like the 20-Series EQs and 10-Series Compressors, to our cutting-edge Performance and Commercial Audio products – our System Core (SC), DriveRack and ZonePRO lines – dbx provides the tools to accommodate all of your audio needs. This brochure is designed to help you navigate through our many product solutions and find the ones that meet your exact needs.

10 Series

1066 Compressor/Limiter/Gate

Whether you're looking for "heavy" compression or subtle gain leveling, the 1066 stereo compressor/limiter/gate with selectable hard knee or OverEasy® compression is ideal. The 1066's compressor section allows you to set attack and release times manually or automatically using our convenient Auto Mode. In addition, our famous Contour switch allows you to smoothly compress entire mixes while preventing low frequencies from punching holes in the overall mix.

The 1066's gate section enables you to clean up unwanted frequencies or mic bleed using its frequency-dependent gain control and the Side Chain External button. With the Side Chain Monitor button and an equalizer, you can select which frequencies will trigger the gate. For overall speaker protection, our innovative PeakStopPlus™ technology prevents unwanted transients from blowing your drivers and minimizes the distortion common to many other "hard" limiters.

1046 Quad Compressor/Limiter

Each of the 1046's four channels allows you to individually select between our classic OverEasy® or hard knee compression, as well as connect each channel for separate purposes. Additionally, our PeakStopPlus™ circuitry is the most comprehensive limiting technology available. For easy interfacing with other devices, each of the 1046's channels also utilizes balanced, gold-plated XLR and ¼" inputs and outputs and switchable +4dBu or -10dBV operating levels. The 1046 incorporates our standard-setting designs, state-of-the-art manufacturing techniques, and of course, our highly sought-after sound quality.

Image: Front panel of the 1074 Quad Gate and 160A Compressor/Limiter.

1074 Quad Gate

The 1074 Quad Gate is the perfect companion to the 1066 and 1046. The 1074 offers 4 channels of gating with threshold, depth, and release controls on each channel. The 1074, like the rest of the products in dbx's® 10 Series, is based on the legendary dbx V2 VCA and offers XLR inputs and outputs, and ¼" side-chain input. In addition to an external key input per channel, the 1074 also has an internal filter that can be independently activated and controlled on a channel-per-channel basis. This filter allows the 1074 to not only clean up tracks but gives you frequency selective control on each gate, to open exactly when you want it to.

160A Compressor/Limiter

The 160A offers such time-tested features as switchable OverEasy® and hard knee compression, extremely wide threshold ranges, and controls for ratio and output gain.

The 160A also includes true RMS level detection, providing the most transparent dynamics processing available – from smooth, subtle compression to "brick wall" peak limiting. Its electronically balanced output stage is an outstanding driver for long cable runs (an output transformer is optional). With its unique "INFINITY +" inverse-compression mode, the 160A actually decreases the audio output level below unity gain when the input exceeds threshold. You can even stereo-couple two 160A's to process a stereo mix without shifting the left/right image. The dbx 160A is truly the standard for dynamics processing.

266XL Compressor/Gate

The 266XL delivers everything from mellow "leveling" to aggressive peak limiting.

The 266XL puts pleasing compression and smooth gating within reach of everyone. The classic dbx® compression delivers everything from mellow "leveling," to aggressive peak limiting. In addition, the 266XL's AutoDynamic™ circuitry continuously adjusts attack and release settings in real time in order to optimally match program material. The advanced gating circuitry in the 266XL uses a program-dependent timing algorithm to produce ultra-smooth release characteristics – even with complex signals. Thanks to the dynamic range of the dbx® VCA, the 266XL can provide reliable gating for any circumstance.

The 266XL also includes separate LED ladders measuring gain reduction, compression threshold, and gate threshold, making the 266XL intuitive and easy to use.

Crossovers

223/234 Crossovers

Crossovers may do nothing more than direct frequencies, but the thought that went into the 223 and 234 is what really elevates the dbx® crossovers above the rest. The 223 and 234 both feature differentially balanced TRS ¼" inputs and outputs. To prevent accidental changes of critical settings during performance (which could be disastrous), several of the 223 and 234's controls are located on their rear panels. On the 223, the first of these selects between stereo two-way or mono three-way operation, while on the 234 it selects between stereo two-way, stereo three-way, or mono four-way operation (the selected mode is always visible via two front panel LEDs). Also located on the back panels are switches that allow you to individually select crossover frequency ranges for both channels (again, the front panels feature LEDs to indicate when the back panel x10 switch is activated). The rear panels also allow you to mono-sum the low frequency outs. Both crossovers feature Linkwitz-Riley 24dB/octave filters – the professional standard. Each of the units' channels has a +12dB input gain control and a recessed 40 Hz low-cut (high-pass) filter for removing low frequency rumble. Both the low and high outputs on each channel have phase reverse switches (reconfigurable to operate as mute switches) and gain controls ranging from ∞ to +6 dB, allowing level matching and muting of individual outputs. The 223 and 234 give you great performance, the features you expect from professional crossovers, and the reassurance that you're buying from the company that has been making the world's finest audio gear for over 30 years.

AFS™ 224 Advanced Feedback Suppression Processor

From now on, the only feedback you'll be getting is positive.

The AFS™ 224 Advanced Feedback Suppression processor has been designed to provide state-of-the-art feedback elimination processing, while maintaining a simple and intuitive control interface. The AFS 224 utilizes a no-nonsense user interface providing all the processing and control necessary for both installation and live use, while the AFS is an absolute must for any live sound application. Ten and twelve filter-per-channel feedback elimination processors have become the de facto standard, but the engineering staff at dbx® have never been content residing in the neighborhood of the status quo. So, to raise the bar once again, they developed a dedicated feedback suppression processor that offers up to 24 filters per channel with filter Qs as narrow as 1/80 of an octave. With such narrow filter Qs, the AFS 224 is able to remove unwanted feedback while preserving the sonic integrity with precision and accuracy. To achieve these staggering numbers, dbx utilized their patented AFS technology that had previously only been available in the upper echelon of dbx products and made it available in this stand-alone processor. In addition to the plethora of feedback suppression filters available, the AFS 224 also offers selectable modes, live filter lift, and multiple types of filtration.

120A Subharmonic Synthesizer

Unlike other attempts at bass synthesis, the 120A's patented subharmonic synthesis process produces smooth, musical low frequencies that don't interfere with mid- or high-band information – even at maximum levels. The result is unmatched low-end punch at levels that won't destroy your system. In fact, the 120A is optimized to allow audio professionals to get the most out of their high-performance, low-frequency speaker systems, and includes both a subwoofer output (with its own level control) and main outputs that can be configured as either full-range (including synthesis) or high-frequency-only.

286A Mic Preamp Processor

The 286A is a complete "channel strip" mic preamp/processor featuring OverEasy® compression, de-essing, enhancing, expanding, and gating all in an incredibly pure signal path. In addition, the 286A boasts a wide-ranging input gain control (+10 to +60dB), switchable +48V phantom power, and an 80Hz high-pass filter. Not to mention that its preamp and five processors can be used independently or in any combination. Its floating, balanced XLR mic input accepts balanced or unbalanced inputs; a ¼" TRS phone jack accepts both balanced and unbalanced line signals.

PB-48 Patch Bay

The PB-48 patchbay features 48 front panel and 48 rear panel patch points, with 24 user-adjustable board assemblies that can be configured – without soldering or wire cutting – for half-normalled or de-normalled operation. Rugged and noise-free, the PB-48 is designed to serve all your patchbay needs. Whether you want clear and easy access to your mixer and studio gear, reduced wear on your equipment's jacks, or the ability to quickly re-route devices within your setup, the PB-48's balanced TRS and unbalanced TS ¼" plugs pave the way.
