dbx ZonePRO 641 6x4 Digital Zone Processor;

The dbx ZonePRO 641M 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. Auto warmth, 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. 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.
