HD MADI Back Panel
HD MADI has the following back panel features:
MADI Optical In and Out
HD MADI provides 2 sets of MADI Optical In
and Out ports. Using high-quality optical cable,
connect these ports to the corresponding MADI
optical inputs and outputs of MADI-compatible
audio equipment, such as routers, digital mixing
consoles, and converters.
MADI Coaxial In and Out
HD MADI provides 2 sets of MADI Coaxial In
and Out ports. Using high-quality coaxial cable,
connect these ports to the corresponding MADI
coaxial inputs and outputs of MADI-compatible
audio equipment, such as routers, digital mixing
consoles, and converters.
Number of Channels
For Pro Tools sessions at 44.1 and 48 kHz, up to
64 channels of MADI Optical I/O are available
through each set of inputs (Optical or Coaxial).
At higher sample rates, both sets can be used to
achieve up to 64 channels of MADI Optical or
Coaxial I/O as shown in the table below.
Real-Time Sample Rate Conversion
HD MADI inputs can stream in at any sample
rate and be converted to the current Pro Tools
session sample rate using hardware-based real-
time sample-rate conversion (SRC). SRC is also
supported on output.

The maximum length for MADI optical
cables is 2 kilometers (SC FDDI fiber-optic
cable).
HD MADI supports 75 Ohm coaxial (BNC)
cable (such as Belden 1855 and 1694 type).
The maximum length for copper MADI co-
axial cables is 100 meters.
