dbx ZonePro 1261m
12x6 Digital Zone Processor
The ZonePRO 1261m 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 1261m features a total of 12 inputs and six outputs. Inputs include six balanced mic/line switchable terminal block inputs, four mono-summed pairs of unbalanced RCA inputs and one S/PDIF input for up to two digital channels. Hardware-controlled
microphone gain allows adjustment of microphone gain per channel.
The 1261m 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 1261m 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 1261m via Ethernet or RS-232. The Configuration Wizard within ZonePRO Designer guides users through the step-bystep configuration process of the 1261m.
