About DBX ZonePRO 641M – 6×4 Digital Zone Processor

The dbx ZonePRO 641M – 6×4 digital zone processor offers fixed I/O, pre-configured architecture, configurable insert processing and optional duplication of audio channels to another ZonePRO device via a link bus. The 641m features a total of six inputs and four outputs. Inputs include four balanced mic/line switchable terminal block inputs and two mono-summed pairs of unbalanced RCA inputs. Hardware-controlled microphone gain allows adjustment of microphone gain per channel. The 641m device has a pre-configured architecture with input processing, a central matrix and output processing. Two input insert positions and one output insert position allow channel-specific insert processing to be configured. AutoWarmth®, a psychoacoustic function that maintains full frequency bandwidth even when the signal level has dropped, is permanently available on each output zone. A link bus allows duplication of the first six audio channels to another ZonePRO device in applications where additional output zones are required.

The front panel of the 641m features a power status LED, a network traffic LED, and an RS-232 control port. Additional system control is offered in the form of optional Zone Controllers. This collection of hardware wall-controllers represents a series of simple, elegant user interfaces for functions such as volume, source and preset control. All ZonePRO devices can be controlled by third party control systems via RS-232 or Ethernet as applicable (see table for further information). ZonePRO Designer—the configuration, control and monitoring software for the ZonePRO family of devices—offers control of the dbx ZonePRO 641M – 6×4 digital zone processor via Ethernet or RS-232. The Configuration Wizard within ZonePRO Designer guides users through the step-by-step configuration process of the 641m. The ZonePRO® products have long been the obvious choice for managing commercial audio applications. They’re easy to install and use – thanks to step-by-step setup wizards – and they’re backed by long track record of dbx reliability. The fact that so many are in use in locations worldwide speaks to their popularity and dependable performance.
