Digital Microphone Interface and Power Supplies
Digital Microphone Interface DMI-2
Equipment that supports the new AES 42 standard can process the
output signals of Solution-D microphones directly. In all other cas-
es, the DMI-2 digital microphone interface is used. The DMI-2 is a
separate, two-channel device which converts the AES 42 data for-
mat supplied by the microphone into an AES/EBU signal. An eight-
channel version is under development.
The DMI-2 is operated via the Neumann RCS remote control soft-
ware, which is installed on a desktop or laptop computer. The com-
puter is connected to the DMI-2 via a USB port and a USB to
RS 485 interface converter. If a large number of microphones is
used, several DMI-2s can be cascaded. In this case, each digital mi-
crophone interface can be addressed individually.
In addition to a word clock input and output, the DMI-2 also has
an internal word clock generator. If no master word clock signal
(e.g. from a mixing console) is present at the input, the DMI-2 in-
ternal word clock is used automatically to synchronize the two mi-
crophone channels, and the signal is switched to the word clock
output.
External commands such as „On Air“ (red light) can be controlled
via a 9-pin user port.

Connection Kit S/PDIF
The Connection Kits serve to supply
power to digital microphones, which are
in accordance with the AES 42 standard.
The microphone audio signal is made
available at the Connection Kit output in
S/PDIF or AES/EBU format, depending
upon the model. The remote control and
synchronization capabilities of the
AES 42 standard cannot be used with
the Connection Kit; they are operable
only with the DMI-2.
