DriveRack® 220i	DriveRack® 220i

Visionary Design

Designed to provide all the necessary tools for con- tractors, the DriveRack® 220i is truly a one stop solution. With a full complement of processing features and Mic/Line inputs with phantom power, the 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 is your entire audio toolbox in a single rack space. The intuitive DriveWare GUI is the primary inter- face for controlling the configuration and parame- ters of the processing modules and utilities. Modules can be accessed, edited and saved as part of programs, which can then be recalled from either the front panel, the GUI, or wall mounted dbx Zone Controllers. Zone Controllers can also be used to provide programmable end-user control like volume adjustment and muting. Besides load- ing programs, the front panel can also be used to clear Feedback Suppression Filters or can be locked out to further prove that the days of the security panel are over.

The DriveRack® 220i is the Contractors Toolbox. For more information please visit www.driver- ack.com or www.dbxpro.com.

Example Applications

All parameters, functions, and utilities can be accessed from the DriveWare PC GUI. The DriveRack 220i also allows limited control from the unit front panel and from wall mounted Zone Controllers.

For Dynamics control, the 220i offers a classic dbx Compressor, Gate or Auto Gain Control in the input section. The outputs also feature a Dynamic insert that includes a Limiter, Compressor, Gate, and Auto Gain Control.

Bandpass Filters are provided on both out- put channels for limiting bandwidth and creating Crossovers.

There are two insert processing positions in the input signal path that allow the following DSP modules: Advanced Feedback Suppression, Auto Gain Control, Compressor, Gate, Ducker, Sub-Harmonic Synthesis, Notch Filter, De-Esser or Wire if no additional processing is desired. The outputs also feature a dynamics insert mod- ule with Limiter, Auto Gain Control, Compressor, and Gate available.

The DriveRack 220i provides both input and output EQ. Input EQ is switchable between a 28-band or 15-band Graphic EQ, or a 9-band Parametric EQ; the out- put EQ is a 4-band Parametric EQ.

The DriveRack 220i offers up to 1.3 Seconds of Delay, with up to 650 mSec per output in 20 microsecond steps. Outputs also offer both Polarity and Phase control.

220 specifications

The dbx Pro 220 is a powerful and versatile audio processing tool designed for professional sound engineers and musicians. This dynamic range processor combines advanced technologies and user-friendly features, making it an essential addition to any studio or live sound application.

One of the standout features of the dbx Pro 220 is its dual channel architecture, allowing users to process stereo signals effectively. Each channel is independently adjustable, giving users the ability to customize audio processing for different sound sources. The unit offers a comprehensive range of controls, including threshold, ratio, attack, release, and output gain, ensuring precise management of dynamic range.

Additionally, the dbx Pro 220 is equipped with dbx’s renowned compression and expansion technologies. The adaptive attack and release times ensure that the processor responds appropriately to varying input levels, maintaining sound integrity and clarity. This feature is particularly useful in live sound situations where varying dynamics can affect overall audio quality.

Another key characteristic of the Pro 220 is its integrated de-esser. This feature allows engineers to minimize sibilance in vocal recordings without compromising the brightness of the sound. The de-esser is adjustable, enabling users to control the frequency range and threshold settings to tailor the effect according to their specific needs.

The dbx Pro 220 also includes a built-in peak limiter to prevent signal overload, ensuring optimal audio quality without unwanted distortion. This is crucial when dealing with high sound pressure levels in live performance settings. Furthermore, the unit provides a comprehensive metering system, allowing users to visually monitor input and output levels, making it easier to make informed adjustments.

In terms of connectivity, the Pro 220 supports both balanced 1/4” TRS and XLR inputs and outputs. This flexibility allows for seamless integration with a wide range of audio equipment, from mixing consoles to studio interfaces. The unit’s robust build quality ensures durability in both studio and road environments.

In conclusion, the dbx Pro 220 is a reliable and feature-rich dynamic range processor that stands out in both studio and live sound applications. With its advanced compression, expansion, and de-essing features, along with the ability to finely tune dynamic processing, it offers sound engineers enhanced control over their audio mix. Whether for recording, mixing, or live performance, the dbx Pro 220 delivers exceptional performance and is a crucial tool in any audio professional's arsenal.
