3.13. MADI Connectors

The rear of the M-32 AD Pro features independent optical and coaxial MADI (AES10-2003) I/O.
Each input receives up to 64 audio channels. Auto Input (see Section 9.2.2, "Connecting Two Identical
MADI Signals for Redundancy") can be activated to treat both inputs as one.
The optical "subscriber" or "square" connector (SC, IEC 61754-4) accepts both simplex and duplex
multimode (MM) fibers of 50 and 62.5µm diameter and up to 2 km length.
The coaxial BNC connector accepts coaxial cables with 75Ω impedance.
On the device, the characteristics and state of the signal at either input can be inspected in the INPUT
section.
The presence or loss of a signal at either port is indicated on the standby screen if
• the input port is selected as clock master, or
• its audio channels are routed in the OUTPUT section.
When using the web remote, the characteristics and state of the signal at either input can be inspected
in the CLOCK section.
