3. Description
The DMI-8 provides power and remote control for
digital microphones that operate in accordance
with the AES42 standard (see www.aes.org).
The most important features of the DMI-8 are as
follows:
• Providing a power supply and remote control of
8 digital microphones (in accordance with the
AES42 standard).
• Receiving and processing the audio data of the
microphone.
• Generating output signals in AES/EBU, ADAT
and GN format.
• Synchronizing the microphones with the DMI-8
word clock, in accordance with the AES42
standard Mode 2 (see Section 7.4 Synchroniza-
tion)
• Automatically synchronizing the DMI-8 to an
external synchronization signal (word clock or
AES11)
• Supporting all standard sampling rates: 44.1 /
48 / 88.2 / 96 / 176.4 / 192 kHz.
• Providing a computer interface – control bus
(RS 485) – for transmitting and processing
bidirectional control data. For this purpose,
Neumann supplies the RCS remote control soft-
ware for use with a PC or Mac.
• Providing a user port for direct control (via a
switch contact or low-active signal) of selected
functions (Mute, LED 1 and LED 2).
• Cascading multiple (DMI-8 or DMI-2) devices.
• Maintaining all settings for connected mi-
crophones in the DMI-8. When the power is
switched on, these settings are transmitted to
the microphones via the remote control data
stream; no computer connection is required.
Indicators (Fig. 1)
POWER
Indicates that the equipment is ready for opera-
tion. During the startup process, the indicator
shines less brightly.
VALID
Indicates a valid AES42 data stream from the mi-
crophone to the DMI-8. The indicator blinks while
the microphone is being synchronized. It shines
continuously when a valid data stream is being re-
