Digital Broadcast Technology
Applications
In the Studio
Save cable and hassle by using fibre!
The 52/MB concentrates up to 56 input signals and 56 output
signals from copper lines into one thin fibre optics cable. Running
on MADI, you can connect it to any mixer, router or other device
with a MADI port. The 52/MB is flexible – it allows to combine
different modules to match your application (see back page for
details). Within a DHD system, the breakout box provides remote
control of microphone preamp gain, GPIO and logic integration.
A 52/MB is the perfect choice if you need to place signal
connectors away from a DHD DSP Frame or any other MADI
enabled device.

On the Road
Get rid of that bulky copper multi-core!
For a long time, MADI has been the
dream of OB operators, but the cables
were too fragile for daily use on the
road. But now you can use heavy-duty
steel-armed fibre cables and rugged
lens connectors within a DHD system.
With this setup, the stage can be 500
metres or more away from the OB van.
However, you still get up to 56 audio
channels both ways including
microphone preamp gain control and
GPIO integration. It is all travelling on
fibre, so you only need one cable drum.
Features and Example Setups
Flexibility
Control
Integration
Often you need to connect several signals over
a long distance. Instead of using many copper
cables, put a 52/MB frame in and link it with
fibre to your router or mixer. One 52/MB will
provide up to 56 inputs and 56 outputs
simultaneously – you just have to select the
audio modules you need – analog, digital or
even HD-SDI.
The 52/MB is easy to control: If you are using
microphone inputs, you can remotely control
the preamp gain from a DHD mixer console.
The necessary control messages travel
“inband” on the fibre link, so there is no
additional cable required. GPIOs work in a
similar way, their states are also transmitted on
the fibre. If you wish, you can control the
parameters of the 52/MB over Ethernet using a
web browser or an open control protocol.
Of course the 52/MB will perform best within a
DHD system, giving you full control from the
DHD mixer console. But if you need to
integrate with other equipment, all options are
there. The 52/MB will work with any MADI
enabled device, however control commands
need to travel on the Ethernet.
There are different MADI options available:
single MADI, redundant MADI and the rugged
lens connector options for mobile use.
Whatever your requirements are, the 52/MB will perform well in any setup.
Connecting Signals from a Distance
Versatile Signal Breakout
Multicore over Fibre
A typical setup to extend signal connections for
DHD systems.
A smart I/O frame for edit suites and audio
workstations.
Use two 52/MB systems to connect signals via
fibre between mixer and stage or studio.
• The 52/MB converts signals from XLR to MADI
and back.
• You can control microphone preamp gain from
the DHD console.
• Audio, control and GPIO signals travel all on
the same fibre link.
• Pick the modules to match your application:
analog, digital or SDI.
• Put a MADI card in your PC and enjoy the
sound quality of the 52/MB.
• Remote control microphone preamp gain
from your PC.
• Transparently route signals over long
distances without quality loss.
• Only one fibre link is necessary for audio and
control command.
• Change the parameters in the 52/MB from a
web browser or with an open control protocol.
