DBX DRIVE RACK STUDIO MONITOR MANAGEMENT SYSTEM

DRIVE RACK Studio Monitor Management System

The dbx Professional Products DriveRack Studio provides all of
the tools necessary to optimize Studio Monitor management in
a single rack mount chassis design regardless of the environment.
The DriveRack Studio offers dual XLR inputs and six XLR outputs,
dual channel graphic EQ, classic dbx Compression, multiple
crossovers, parametric EQ and a built-in real time audio analyzer.
In addition, this audio toolbox provides the end user with 24 custom
presets that have been specifically written and designed to work in
tandem with the most popular studio reference monitors available.
The DriveRack Studio now allows you to fine-tune even the most
sonically challenged rooms.
The DriveRack Studio continues the legacy of DriveRack series,
which has been created by the company that has been redefining
the standard of signal processing for more than 30 years. The DriveRack
Studio was designed with the purpose and vision of providing state-of-
the-art signal processing in the studio environment, while utilizing a
simple and intuitive user interface. This goal has been achieved by
offering two independent channels of processing power with a linkable
28-Band Graphic equalizer, industry-standard dbx? stereo compressor
module, feedback eliminator and the 120A Subharmonic Synthesizer on
the input, with a six channel output system that includes parametric EQs,
and Peak Plus? limiters (which are used to provide protection against speaker
blowouts) and alignment delay. These features combined with the Wizard
setup system, represent a methodical design that is guaranteed to deliver
optimal, all-inclusive processing in a completely scalable system.

With 6 inputs and 4 outputs the dbx ZonePro? 640 and 641 provide flexible signal routing,
powerful DSP processing and multiple control interfaces for Commercial Audio applications.
Designed to offer superior system sonic performance and flexibility, the 640/641 deliver the
highest quality tools available. Even the input and outputs connectors were chosen for their
standard usage and reliability. The ZonePro products offer Euroblock connectors for balanced
signals and RCA connectors for interfacing with consumer equipment often used in commercial
applications; there is also a simple analog input buss that allows inputs to be sent from one
unit to the next for unit and job scalability. The 640 and 641 provide every necessary processing
tool, from the input processing like gain control and EQ available on all inputs to highly sophisticated
and specific functions such as selectable paging microphone processing including Gating,
De-Essing, Auto Gain Control, Compression and Feedback Suppression. The heart of the
ZonePro products is the Routing module that provides of course Primary Source Selection
but also Source Ducking for Paging and Priority Override. The outputs also offer a wealth of
processing designed for commercial applications like our patent-pending AutoWarmth? function
that was co-developed with JBL to provide natural low frequency extension at any signal level.
Each output also offers EQ, Bandpass and Crossover filters, Limiting and Delay for system
optimization. With the ZonePro? every tool is at your disposal to maximize the response of
your system.
Beyond processing, the ZonePro? products offer multiple forms of control to further extend the
versatility of your system. From easy-to-use wall panel Zone Controllers for standard end-user
functions like source select and volume control to advanced system control including a built-in
Real Time Clock that can provide programmable system changes throughout the day or week.
For system setup and monitoring the ZonePro Designer software provides an intuitive interface
and a speedy setup Wizard for configuring and editing all system parameters.

The ZonePro? 640 and 641 will take your Commercial Audio system to the next level with advanced
processing, versatility and control.

Providing 48-bit filter algorithms, 24-bit AD/DA conversion and a dynamic range of 115 dB, the DSP 244 sets new standards for digital loudspeaker controllers and processors. The DSP 244 is an universal Digital Sound System Processor that provides 2 inputs and 4 outputs; plus internal summing of the inputs 1 and 2. Via matrix it is possible to assign the outputs to any input or to the sum of the inputs. It is further possible to establish the following configurations: Stereo or Dual 2-Way systems, 3-Way + Direct and 4-Way systems, each with Mono Subchannel, but also full range systems. High and low-pass filters are provided for the frequency crossover functions in all operation modes. The selection includes Linkwitz-Riley, Butterworth and Bessel type filters with switchable slopes between 6, 12, 18 and 24 dB/oct. A huge number of additional filters offers extremely flexible correction of the frequency response. Each input incorporates a 5-band equalizer, allowing to assign high and low-pass, high and low-shelving or parametric peak-dip filters to its individual filter sections. Next to the frequency crossover filters, four additional filters are employed in each output channel, which also can be set to work as high or low-pass, high or low-shelving filters, parametric peak-dip filters, or all-pass filters. Additional filtering is provided through 2. order high-passes for the realization of B-6 alignment, or special LPN-filters (Low-Pass Notch filters) for correcting the frequency and phase responses of optimally vented woofer cabinets. Each channel additionally provides a delay, a polarity switch, a programmable level control and a digital compressor / limiter while the master delays are located in the input channels.
