RME M-32 AD Pro II – 32-channel, 192 kHz MADI A/D converter for premium studio, broadcast and live installations. It provides thirty-two balanced analog line inputs via 4 × DB-25 connectors (DC-coupled; selectable reference levels up to +24 dBu), MADI I/O (coaxial BNC onboard plus optional optical SFP, up to 128 ch), Word Clock I/O, and USB 2.0 for remote control and firmware. A 2″ color display with push-encoder, tri-color backlit channel labeling/meters, and comprehensive remote control (web UI, HTTP/JSON, MIDI-over-MADI; optional legacy MIDI) streamline setup and operation. Dual monitored internal PSUs add true redundancy, while SteadyClock FS and SyncCheck® ensure ultra-stable clocking. Converter performance is reference-class, with up to 123 dB(A) dynamic range and AD THD+N down to −120 dB.
