The dbx ZonePRO 640m is a digital zone processor with a fixed I/O, preconfigured architecture, configurable insert processing, and optional duplication of audio to an additional ZonePRO device via a link bus.
The unit features six inputs with four balanced mic/line switchable terminal block inputs and two unbalanced, mono-summed RCA input pairs. There is hardware-controlled microphone gain per channel. The pre-configured architecture has input processing with 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.
The front panel features comprehensive signal metering, a well-spec'd LCD display and user-specified front panel control. Additional system control is offered in the form of optional zone wall-controllers, which provide simple 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. The Configuration Wizard within ZonePRO Designer guides users through the step-by-step configuration process of the 640m. The dbx ZonePRO 640m ships with a power cord, a set of rack screws, and an RS-232 modem cable.
