A32 inputs and outputs

A32 inputs and outputs – MADI
MADI is a professional audio format, which can transfer 64 channels
over a distance of up to 2 kilometers.
When connecting several MADI devices in series you need to put them
in a daisy chain. This means that you connect the output of the first
device to the input of the second device and so on. This way you can
connect two units to transfer 64 analog inputs and 64 outputs.
The A32 has an optical and a coaxial MADI port. Both ports can be
used simultaneously for redundancy purposes. When using the
SMUX/4 mode, each port transfers only 16 channels, so both ports will
be used to transfer all 32 analog channels.
Use either optical fiber cables (SC connectors) or coaxial cable with an
impedance of 75 ohms (BNC connectors) for MADI.
Both kinds of cabling have their own advantages and disadvantages.
Due to optical transmission, fiber cables cannot be influenced by
electromagnetic crosstalk and can be used for distances up to 2 km.
Ferrofish also offers a single mode MADI version of the A32 on
request, which lets you transfer audio signals up to 10km. Please
contact us for more information.
Keep in mind that an optical fiber may break if bent too much.
Coaxial cables with an impedance of 75 ohms are widely used and easy
to source. Unless using armored optical fiber they are more robust, but
are limited to a length of 100 meters.
