M-32/M-16 AD
T
he M-series is an unsurpassed flexible basis for the realization of multichannel setups. Combinations of the M-16 AD and M-32 AD converters
allow setups with 16, 32, 48, or 64 channels, according to your individual application or budget. Up to four M-16 AD and up to two M-32 AD
can be connected in series via MADI, sending up to 64 channels over a single MADI line to the digital receiver. The unit’s unique set of features
includes analog limiters, three hardware reference levels up to +24 dBu, MADI and ADAT I/O up to 192 kHz, 6.3 mm TRS and D-sub inputs, remote
control via MIDI, and operation across a wide range of mains voltages, all packed into a 2U enclosure.
Reference Converter. The M-32 AD offers an outstanding AD conversion to MADI and ADAT formats. Balanced analog inputs based on RME’s reference
design from the ADI-8 QS guarantee excellent S/N and THD specs across a wide analog level range. Using up-to-date converter technology, the device
not only works up to 192 kHz, but also reaches a real-world signal-to-noise ratio of 116 dBA – on all channels.
Limiter. An extraordinary 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).
Technologies. SteadyClock
TM
guarantees perfect sound quality through 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 in case of failure of the external source. Other renowned RME technologies like SyncCheck allow quick detection of clock
problems. All settings are retained when the unit is powered off. 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.
Remote Control. 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, allowing separate controllability of several units with a single MIDI
channel. Control software for Mac and PC is supplied and allows easy remote control, also with MIDI transfer via MADI (MIDI Extender).
ADAT. 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.
Stacking. The MADI input serves as optional external clock source, but also as MADI passthrough 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 second unit.
Delay Compensation. Serial connection of devices via MADI will cause a delay of 3 samples from MADI input to output, thus the MADI signals of
preceding converters will arrive delayed at the input of the last unit in the chain. The M-series includes an internal auto correction, which ensures
sample-synchronous data at the last unit’s output.
