Аналого-дигитален конвертор RME M-16 AD

Features

The M-16 AD offers an outstanding AD conversion to MADI and ADAT formats in a compact 19″ unit with only 2U height. The 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. Three different hardware levels are available. 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.

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 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, also with MIDI transfer via MADI (MIDI Extender).

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-16 AD’s two 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.

Stacking

The MADI input serves as optional external clock source, but also as MADI pass-through input. Since the M-32 AD uses only 16* 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 32 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. One M-16 AD can be combined with one or two M-16 AD, as can be up to four M-16 AD. Of course, the units can be synced with sample accuracy by word clock.

Notes

The number of channels that can be achieved with MADI depends on the sample rate range. At 48 kHz there are up to 32 channels, at 96 kHz 16, at 192 kHz 8 channels. Therefore at 192 kHz the M-16 AD can only work as 8 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-16 AD can convert only 8 channels via its four ADAT ports.
