\n

The ZonePRO 640m offers fixed I\/O, pre-configured architecture, configurable insert processing and optional duplication of audio channels to another ZonePRO device via a link bus.<\/p>\n

 <\/p>\n

The 640m 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.<\/p>\n

 <\/p>\n

The 640m 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\u00ae, a psychoacoustic function that maintains full frequency bandwidth even when the signal level has dropped, is permanently available on each output zone.<\/p>\n

 <\/p>\n

A link bus allows duplication of the first six audio channels to another ZonePRO device in applications where additional output zones are required.<\/p>\n

 <\/p>\n

The front panel of the 640m features comprehensive signal metering, an informative LCD display and user-specified front panel control.<\/p>\n

 <\/p>\n

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.<\/p>\n

 <\/p>\n

All ZonePRO devices can be controlled by third party control systems via RS-232 or Ethernet as applicable (see table for further information).<\/p>\n

 <\/p>\n

ZonePRO Designer\u2014the configuration, control and monitoring software for the ZonePRO family of devices\u2014offers control of the ZonePRO 640m via Ethernet or RS-232. The Configuration Wizard within ZonePRO Designer guides users through the step-by-step configuration process of the 640m.<\/p>\n
