Description
The dbx ZonePRO 641 is a digital zone processor with six inputs and four outputs for commercial audio in bars, clubs and houses of worship. It takes two switchable mic/line inputs on Euroblock connectors and four RCA source inputs, and it is set up and run from ZonePRO Designer software, ZC wall controllers or RS-232 control.
Every input has gain and EQ, and paging microphone inputs can add gating, de-essing, auto gain control, compression and feedback suppression. The routing module picks the source for each zone and ducks it for paging and priority override. Each output has EQ, bandpass and crossover filters, limiting, delay and AutoWarmth, which was co-developed with JBL to keep natural low-frequency extension at any level. A built-in real-time clock changes settings through the day or week, and ZonePRO Designer software sets up the system with a wizard.
