The dbx ZonePRO 640 is a professional 6-input, 4-output digital zone processor designed for commercial audio installations. It delivers flexible signal routing, powerful DSP processing, and multiple control interfaces to optimize sound across restaurants, retail spaces, conference rooms, houses of worship, and other multi-zone environments.
Built for reliable performance, the ZonePRO 640 features balanced Euroblock inputs for microphones and line sources, plus unbalanced RCA inputs for consumer equipment. A simple analog input bus allows scalable expansion, sending signals from one unit to the next. Each input supports gain control, EQ, and sophisticated paging processing including gating, compression, de-essing, auto gain control, and feedback suppression.
At the core of the ZonePRO 640 is a versatile routing module offering primary source selection, source ducking for paging, and priority override. Outputs include AutoWarmth® low-frequency enhancement, EQ, bandpass and crossover filters, limiting, and delay, giving you full control to optimize each zone’s sonic performance.
The ZonePRO 640 also supports multiple control options, from user-friendly wall-panel Zone Controllers for volume and source selection to advanced system management via built-in Real Time Clock scheduling and third-party control via Ethernet or RS-232. Setup and monitoring are streamlined with the ZonePRO Designer software, featuring an intuitive interface and step-by-step configuration wizard.
