Standalone D21m I/O System
Previously only available for Studer digital mixing consoles, the D21m I/O
system is now opened up for use with any audio equipment. With the intro-
duction of the D21m remote control software, the microphone amps and A/D
converters become available to a wide range of applications, such as record-
ing, broadcast, and live sound.
A D21m I/O frame can be connected to any 3rd-party device using its optical
MADI interface. The remote control software runs on a PC, connected to the
I/O frame over an additional RS422 serial connection. This software may
even rut at the same time as DAW software.
The I/O frame itself is highly modular, and it is possible to select from a
variety of I/O cards. Thanks to the two MADI interfaces the D21m I/O keeps
its channel count high even in 96 kHz mode. This makes this product ideal
for any use with a Digital Audio Workstation (DAW). In 48 kHz mode the
second MADI interface interface serves as a digital split output for feeding
any additional audio device or as a redundant audio link.
In facilities containing Studer Vista consoles, the investment is broadened by
the extreme versatility of the D21m stage boxes. One day they can be used
on stage, connected to the Studer console, and the next day in the recording
studio in order to bring superb audio quality to lower-cost recording equip-
ment.
Remote Software
The control software is an application running under Microsoft Windows
XP on any regular PC with an RS422 serial port. The software automati-
cally detects the connected hardware and allows controlling the microphone
amplifier’s parameters, such as phantom power, high-pass filter, soft clipping,
analog insert, gain, labeling and color coding the inputs, and stereo linking
two subsequent channels.
These parameters may be stored and recalled using snapshot files. Spare
inputs may be hidden from the screen, while the used ones can be arranged
in any order. Operating speed is maximized by the ability to group inputs in
a Vista-like way (“ganging”).
MADI Interface
The MADI IF of the D21m frame supports both the standard MADI protocol
with up to 56 audio channels as well as the extended protocol with 64 chan-
nels. Protocols are selected on the front panel of the frame.
