Portable Digital Microphone Interface

Lebih Lengkap Mengenai Portable Digital Microphone Interface

The Neumann DMI-2 Portable Digital Microphone Interface is an AES42 standard interface and processor for Neumann Solution-D microphones. The DMI-2 converts the AES 42 data format supplied by the microphone into an AES/EBU signal. The unit may be manually or remotely controlled via USB and the supplied RCS remote software. There is support for up to 2 microphones and parameters such as gain, attenuation, and low-cut filter are easily controlled and displayed its monochrome LCD display.

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.
