The RME M-32 AD is a highly specified 32-channel Analogue to MADI/ADAT converter that benefits from the latest converter technology, superior analogue circuit design and RME’s renowned SteadyClock™. The M16-AD is the same in every respect as the M-32 AD except that it only has one 16-channel AD board fitted and its lower power consumption (40W) means that no fan is required.
The M-32 AD’s exceptional set of features includes three hardware reference levels up to +24 dBu, MADI I/O and ADAT output up to 192 kHz, 6.3 mm TRS and D-sub inputs, remote control via MIDI, analogue limiters, and operation across a wide range of mains voltages. A high quality limiter, conceived and optimised for professional studio, stage, and broadcast applications, offers essential operational safety with its capability to limit an input’s overload of up to 17 dB without audible distortion (max. input level + 30 dBu).
The M-32 provides multichannel conversion in reference quality – at an unbeatable price/performance ratio!

SteadyClock™ guarantees perfect sound quality by efficient jitter suppression, making the device completely independent from the quality of external clock signals. Intelligent Clock Control not only displays every clock status by means of flashing LEDs, but will also retain the last valid input sample rate if the external source fails. RME’s SyncCheck makes quick detection of clock problems possible.
All M-series converters are fully remote controllable and configurable via MIDI. Each unit’s complete status can be monitored, including all the front panel’s displays. Individual IDs can be set for each unit, for separated control of multiple units via a single MIDI channel. Control software for Mac and PC is supplied and allows easy remote control, with MIDI transfer via MADI (MIDI Extender).
M-32 AD and M-16 AD have optical and coaxial MADI inputs. In case of failure of an input signal, the source is switched immediately, if a valid signal is present on the other input.
The M-32 AD’s four ADAT outputs provide simple connectivity with other studio equipment. A combination with RME’s HDSPe RayDAT makes a perfect partnership, allowing the transfer of 32 channels into a Mac or PC with regular optical Toslink cables at an unbeatable price. The converter’s ADAT input only serves as an optional source for external synchronization. All settings are retained when the unit is powered off.
The MADI input serves as an optional external clock source and as a MADI pass-through input. Since the M-32 AD uses only 32 channnels of the MADI signal, unused channels of the input signal are fed through to the output. This way, the signals of two or more units can be combined into one MADI stream of 64 channels, with every unit adding its channels to the input signal, resulting in one line at the output of the last unit.
M-32 AD and M-16 AD can be freely combined up to a total of 64 channels. The units can be synced with sample accuracy by word clock.
The number of channels that can be achieved with MADI depends on the sample rate range. At 48 kHz there are up to 64 channels, at 96 kHz 32, at 192 kHz 16 channels. Therefore at 192 kHz the M-32 AD can only work as a 16 channel converter.
The number of channels that can be achieved with ADAT depends on the sample rate range. At 48 kHz there are 8 channels per port, at 96 kHz 4, at 192 kHz 2 channels. Therefore at 192 kHz the M-32 AD can convert only 8 channels via its four ADAT ports.
