Processor dbx ZonePRO 641m

The dbx ZonePRO 641m is a professional processor designed for commercial and public installation environments. It features a fixed architecture with 6 inputs and 4 outputs, including 4 balanced mic/line terminal block inputs and 2 mono-summed pairs of unbalanced RCA inputs. Microphone gain is hardware-controlled per channel for precise adjustments.

The 641m architecture includes input processing, a central routing matrix, and output processing. Two input inserts and one output insert enable flexible, channel-specific processing. Each output zone includes the AutoWarmth® function — a psychoacoustic feature that preserves full frequency bandwidth even at reduced signal levels.

Thanks to the link bus, the first 6 audio channels can be duplicated to another ZonePRO device for seamless system expansion. The front panel features a power indicator, a network activity LED, and a front-panel RS-232 control port.

Additional control is available via optional ZC series wall controllers, which provide convenient interfaces for volume, source, and preset management. Control is also supported via Ethernet or RS-232, with full compatibility with third-party automation systems.

Configuration is handled via ZonePRO Designer software, which includes a step-by-step Configuration Wizard for fast and easy setup.
