The 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. 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 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. 6 Inputs / 4 Outputs 4 Balanced Mic/Line Inputs 2 Unbalanced, Mono-Summed RCA Input Pairs Microphone Gain per Channel Pre-Configured Architecture Two Configurable Input Insert Positions One Configurable Output Insert Position AutoWarmth® per Output Zone Link Bus Optional ZC Controllers Ethernet Control Serial Control Third Party Control Wizard-Driven Configuration
