dbx 640 ZonePro Zone Controller

The dbx 640 ZonePro Zone Controller is a digital processor with 6 inputs and 4 outputs, provides flexible signal routing, powerful DSP processing and multiple control interfaces for Commercial Audio applications.

The dbx 640 ZonePro Zone Controller is designed to offer superior system sonic performance and flexibility, and delivers 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 dbx 640 and dbx 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 dbx 640 ZonePro Zone Controller 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 the dbx 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 dbx 640 ZonePro Zone Controller, every tool is at your disposal to maximize the response of your system.

Beyond processing, the dbx 640 ZonePro Zone Controller offers 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 dbx 640 ZonePro Zone Controller will take your Commercial Audio system to the next level with advanced processing, versatility and control.
