dbx ZonePRO 641m Speaker Processor

The ZonePRO 641m offers fixed I/O, preconfigured 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 preconfigured 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. ZonePRO Designer—the configuration, control and monitoring software for the ZonePRO family of devices—offers control of the ZonePRO 641m via Ethernet or RS-232. The Configuration Wizard within ZonePRO Designer guides users through the step-by-step configuration process of the 641m.
