RME's M-32 DA is a 32-channel high-end DA converter, easy to operate yet having a comprehensive feature set. The unit combines excellent analog circuit design with the latest converter chips and RME's superior SteadyClock, resulting in a state-of-the-art DA conversion - not less than 32 times!

The M-series converters have been conceived and optimised for professional studio, stage, and broadcast applications. Combinations of the M-16 DA and M-32 DA converters allow for setups with 16, 32, 48, or 64 channels, according to your individual application or budget. The unit's unique set of features includes three hardware reference levels up to +24 dBu, MADI I/O and ADAT input up to 192 kHz, 6.3mm TRS and D-sub outputs, remote control via MIDI, and operation across a wide range of mains voltages, all packed into a 2U enclosure.

The M-32 DA extends RME's MADI line with multichannel conversion in reference quality - at an unbeatable price/performance ratio!

Features

The M-32 DA offers an outstanding DA conversion from MADI and ADAT formats in a compact 19" unit with only 2U height. The balanced analog outputs 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 118 dBA - on all channels. The units have separated driver stages for the TRS and D-sub outputs. The servo-balanced TRS jacks will work up to +21 dBu. When selecting +24 dBu the balanced D-sub connector outputs will provide the higher output level while TRS stays at the +19 dBu setting.

SteadyClockTM 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).

The M-series has 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 DA's four ADAT inputs provide simple connectivity with other studio equipment. A combination with RME's HDSPe RayDAT makes a perfect partnership, realizing the transfer of 32 channels from a Mac or PC with regular optical Toslink cables at an unbeatable price.

All settings are retained when the unit is powered off.

Stacking

The MADI input serves not only as audio source and optional external clock source, but also as MADI pass-through input. Since the M-32 DA converts only 32* channels of the MADI signal, all channels of the input signal are fed back to the output. Additional M-32 DA or M-16 DA can be connected serially to convert the remaining signals, in any combination up to a maximum of 64 channels: One M-32 DA with one or two M-16 DA or up to four M-16 DA.

As MADI covers long distances up to 2 km, even the same channels can be converted in several different (electrically separated) locations, with comfortable and unambiguous front panel channel selection.

Notes

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 DA can only work as 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 DA can convert only 8 channels via its four ADAT ports.
