dbx 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 deliver superior system sonic performance and flexibility, the 640/641 offers the highest quality tools available. Even the input and output connectors were selected for their industry-standard use and reliability. ZonePRO products offer Euroblock connectors for balanced signals and RCA connectors for interfacing with consumer equipment often used in commercial applications. There’s also a simple analog input bus that allows inputs to be routed from one unit to the next for unit and workflow scalability. The 640 and 641 provide all the necessary processing tools, from input processing like gain control and EQ available on all inputs to highly sophisticated and dedicated features like selectable processing for paging microphones, including Gating, De-Essing, Automatic Gain Control, Compression, and Feedback Suppression. At the heart of the ZonePRO products is the routing module, which provides, of course, primary source selection, but also source attenuation for paging and priority override. The outputs also offer a wealth of processing designed for commercial applications, like our patented AutoWarmth® feature, which 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 your system's response. Beyond processing, ZonePRO® products offer multiple forms of control to further extend the versatility of your system. From easy-to-use wall-mounted zone control panels for standard end-user functions such as source selection 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, ZonePRO Designer software provides an intuitive interface and quick setup wizard for configuring and editing all system parameters. The ZonePRO® 640 will take your commercial audio system to the next level with advanced processing, versatility, and control.
