Neumann DMI-2 Portable Digital Microphone Interface
Digital Microphone Interface
The DMI-2 portable is the ideal digital microphone interface solution for ENG and other field recording applications. It supports two digital microphones and allows adjustment of the Gain, Pre Attenuation and Low Cut filter settings at the device.
The DMI-2 portable is the ideal digital microphone interface solution for ENG and other field recording applications.
It supports two digital microphones and allows adjustment of the Gain, Pre Attenuation and Low Cut filter settings at the device. The front panel display shows the selected gain and, by means of bar graphs, shows the current signal level and any gain reduction. Of course, these functions can also be operated via the RCS software, which allows complete access to all of the microphone parameters.
Microphone presets can be stored inside the DMI-2 portable and recalled for use in the field.
The Digital Microphone Interfaces in general
Equipment that supports the AES 42 standard can process the output signals of Solution-D microphones directly. In all other cases, the DMI-2 portable or DMI-8 digital microphone interface is used. The DMIs convert the AES 42 data format supplied by the microphone into an AES/EBU signal.
The Interfaces are operated via the Neumann RCS remote control software, which is installed on a desktop or laptop computer. Some parameters of the DMI-2 portable can be accessed directly at the interface. The computer is connected to the DMI via a USB port and a USB to RS 485 interface converter. If a large number of microphones is used, several DMI-8’s can be cascaded. In this case, each digital microphone interface can be addressed individually.
In addition to a word clock input and output, the DMIs also have an internal word clock generator. If no master word clock signal (e.g. from a mixing console) is present at the input, the DMI internal word clock is used automatically to synchronize the microphone channels, and the signal is switched to the word clock output.
External commands such as "On Air" (red light) can be controlled via the 9-pin user port of the DMI-2 and DMI-8.
