DBX 220I SYSTEM PROCESSOR

220i System Processor with AFS? Advanced Feedback Suppression

Designed from the ground up to provide state-of-the-art signal processing,
the DriveRack 220i is the perfect tool for any fixed-install application.
With a full complement of processing features and Mic/Line inputs the
DriveRack 220i can provide both system and microphone processing.
Featuring the new, patent-pending Advanced Feedback Suppression (AFS)
algorithm, equalization, dynamics processing, delay, matrix mixing, and
bandpass filters, the DriveRack 220i will exceed your expectations.

The DriveRack 220i is piloted from the intuitive DriveWare GUI that offers
both Configuration and Control of the processing modules. Modules can
be accessed, edited and saved as part of programs. Processing modules
can be linked between the channels for true stereo processing. If independent
processing is desired, parameters can be copied from one channel to the
next to ensure that setup is quick and easy. Stored programs can be loaded
from either the front panel or from wall mounted Zone Controllers. Zone
Controllers can also be used for output muting or adjusting output volumes.

and musical performance, the AD2055 combines the best of active and passive filter
topologies with sonic excellence unequaled by lesser designs. The AD2055 is the
perfect solution for two buss music-program equalization, special instrument EQ and
FX applications and ultra high performance mastering studio's.

Features include state-of-the-art, balanced 100% discrete, Pure Class A signal amplifiers,
practical user features and rugged hardware designed to deliver true high performance
audio for many years. 

PASSIVE-ACTIVE FILTER DESIGN
Avalon equalizers feature the unique combination of both active and passive filter EQ designs.
This special combination enables the AD2055 to deliver high speed transient detail at the
operational extremes of real-world equalization demands. The passive high and low bands offer
alternate musical tone range to the full function active parametric mid bands. Passive equalizers
have long been a favorite with music lovers around the world.  Full bodied, powerful (up to +/-32dB,
64dB range !) and sweet frequency selections are the benefits of the passive high-low EQ bands.
The full bandwidth twin mid bands provide variable frequency selection (X10 frequency multipliers
for very wide range), variable Q (width) and amplitude control.

MINIMUM SIGNAL PATH DESIGN
Avalon's advanced true symmetry design offers high-voltage, large headroom, extended bandwidth
and very low noise. The use of 100% discrete, Pure Class A signal amplifiers give the serious music
professional unlimited sonic character and a natural harmonic detail that enhances the program
material and becomes one with the music itself. The Avalon AD2055 breathes life!

The latest addition to the 10 Series product line, the dbx® 1074 QuadGate™, 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 10 Series, is based on the legendary dbx V2 VCA and offers XLR inputs and outputs, and 1/4” 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. These features combined, make the 1074 an absolute must for those who require quad gating on applications including: Gating dry and percussive sounds such as snare drum and kick drum,gating sounds that have longer decay times such as cymbals and Pianos, gating hum or buzz from live instruments or recorded tracks or eliminating Headphone leakage into microphones. Gating instrument microphones to eliminate amplifier bleed. 

From the company that has been redefining the standard of signal processing for more than 30 years, dbx® Professional Products comes a bulletproof product that caters to the scrutinizing needs of those who require the precision noise gating capabilities. Once again, the engineering staff at dbx® Professional Products have taken technology that has been over three decades in the making and have created a product that is flexible, versatile and rock solid in construction design. The 1074ʼs independent channel design with key filtering capabilities make it the perfect tool for countless applications.

• Four independent channels of gating
• Independent key filtering
• Independent Threshold and Release controls
• Differentially balanced gold-plated XLR and 1/4" inputs and outputs
• True RMS level detection
• Stereo Coupling mode
• Switchable +4dBu or -10dBv operation per channel
