DBX ZonePro 640 6x4 Digital Zone Processor

With 6 inputs and 4 outputs the dbx ZonePRO® 640 provides flexible signal routing, powerful DSP processing and multiple control interfaces for commercial audio applications.

Designed to offer superior sonic performance and flexibility, the 640 delivers the highest quality tools available. Even the input and outputs connectors were chosen for their standard usage and reliability. The ZonePRO products offer two Euroblock connectors for balanced microphone or line signals (switchable), plus four stereo RCA connectors for interfacing with consumer equipment; there is also a simple analog input bus that allows inputs to be sent from one ZonePRO unit to the next for unit and job scalability.

The 640 provides every necessary processing tool, from the input processing like gain control and EQ available on all inputs to dbx's trademark, 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 allow for not only Primary Source Selection but also Source Ducking for Paging and Priority Override.

The outputs also offer a breadth of processing options that are perfect for commercial applications. For example, dbx’s patent-pending AutoWarmth® function that was co-developed with JBL was included 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.

As an improvement from the dbs 641, the 640 can be controlled not only by ZonePRO Designer (software via RS-232, Ethernet) and wall panel control, but also by it's onboard LCD screen and menu buttons. With the ZonePRO® every tool is at your disposal to maximize the response of your system. Get yours today.
