RME M-16 AD – 16-channel 24-bit/192 kHz A/D converter with TRS 6.3 mm and D-sub 25 (balanced) line inputs, digital outputs MADI (optical SC and coaxial BNC) and 4× ADAT Out, SteadyClock synchronization, Word Clock I/O (BNC), remote control via MIDI and MIDI over MADI, and a built-in Analog Limiter on each channel.
The M-16 AD features a fully balanced analog path and high-end converters, offering three reference levels +13 / +19 / +24 dBu (0 dBFS) while maintaining optimal S/N ratio and low distortion. Parallel MADI and ADAT outputs provide flexible multichannel recording up to 64× @48 kHz (MADI), and cascading with Automatic Delay Compensation. TRS and D-sub inputs are internally connected (not for simultaneous use), and the fanless design ensures silent operation in control rooms.
Clocking and synchronization are handled by SteadyClock, SyncCheck, and Intelligent Clock Control. Full configuration and monitoring are available via front panel, MIDI, or MIDI over MADI. A MADI thru-mode allows unused channels to be passed through the device.
