dbx 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. Can be controlled with Zone Controllers (sold separaetly), and third party control systems via RS-232 or Ethernet as applicable.

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 front panel of the 1261m features a power status LED, a network traffic LED, and an RS-232 control port.

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.
