Tascam MM-2D-X
The MM-2D is an exquisite analogue input/output unit that can either convert two mic/line input signals into two Dante output signals, or two Dante input signals into two line output signals. In addition, it also supports four-channel Dante input/output as well, making it possible to use virtually any audio sources within an established Dante network. Available with Euroblock (MM-2D-E) or XLR (MM-2D-X) connectors for analogue inputs and outputs, this model can be used for a wide range of applications.
The MM-2D is part of the Tascam Dante Compact Processor Series consisting of compact, half-rack size audio converters for Dante/AES67 networks. The models easily add additional mic/line or AES/EBU inputs/outputs to Dante audio networks in public facilities, broadcasting stations, recording studios or upmarket domestic environment and can be freely combined.
A key advantage of the product range is the DSP processor built into each unit. By providing not only mixing functions and EQ but also dynamic processing, automatic level control, auto-ducking, routing and noise compensation, even small systems can fully perform without additional signal processing or mixing devices. From the input of microphone signals to the output of powered speakers or recording devices, the Dante Compact Processor Series can build up a complete small system on their own.
Remote control is possible via two different software applications available for Mac, Windows, iOS and Android devices: Tascam DCP Connect for configuration and Tascam EZ Connect for end users, both of which are simple to use and included with the units. The MM-2D also offers the possibility to mute its inputs and control its output levels via GPI.
All models can be powered by PoE or an optional AC adapter. By using power daisy-chaining, two units mounted side-by-side in a rack can be powered by one AC adapter.
