AMSTERDAM, The Netherlands – In correlation with the
introduction of its D23m I/O system and A-Link 3 Gbit/s optical interface,
HARMAN’s Studer is announcing the first MADI I/O card specifically designed to
fit in the new D23 frame, which works seamlessly with Studer Vista X and Vista
V digital consoles. The card may also be used in the Vista 1 I/O card slot.
The new I/O card is a dual slot card fitted with two redundant MADI interfaces
and provides up to 128 channels of inputs and 128 channels of outputs on the
two fully redundant interfaces. SFP modules are used for the front panel MADI
interfaces and these hot-pluggable devices are available in a variety of
optical and electrical formats.
MADI is a worldwide standard and is used for high capacity interfaces to
much studio equipment such as Digital Audio Workstations (DAWs), video and
audio routers, other consoles and, most importantly, stage boxes. Studer stage
boxes have embedded control within the MADI stream, even if all 64 channels are
used for audio. This new card may be connected to two Studer stage boxes,
either D21m type or the Compact Stagebox. Full microphone control and remote
frame status monitoring for both frames is provided on the console application.
Each of the two MADI interfaces provides dual outputs (with the same
audio and control data). The MADI inputs will automatically switch in less than
a millisecond to the reserve input if the data is corrupt or fails, thus
providing full cable redundancy for typical OB operations.
MADI channel count to the D23m backplane may be set for both interfaces
in eight channel steps individually from eight channels to 64 channels. MADI
outputs may be set to 56-channel mode for compatibility with legacy equipment. MADI
inputs may be in either 64- or 56-channel mode. Input sample rate converters
may be enabled for use with non-synchronous sources.
The MADI interfaces will run at 44.1 kHz, 48kHz, 88.1kHz and 96kHz in
the D23m frame. Channel count is halved unless two pairs of cables are used.HARMAN (www.harman.com) designs, manufactures and markets premier audio, visual, infotainment and integrated control solutions for the automotive, consumer and professional markets.
