RME
M-32 / M-16 AD

Analog limiter, three hardware reference levels up to +24 dBu, MADI I/O and ADAT I/O at up to 192 kHz, inputs via 6.3 mm TRS jacks and D-Sub, remote control via MIDI, operation over a wide mains voltage range, and a chassis only 2 U high make the unit unique. Designed and optimized for professional use in broadcast, studio and on stage, it also includes an exceptional limiter that can cut back analog input overload by up to 17 dB without audible distortion (maximum input level +30 dBu).

The M-32 AD offers reference-level multichannel conversion - with an unmatched price/performance ratio!

The M-32 AD offers exceptional AD conversion to ADAT and MADI on only two U. The balanced analog inputs use RME's reference design from the ADI-8 QS guaranteeing excellent noise and distortion levels. Three different input levels are available to ensure optimal matching at the analog level. The converters used are latest generation AD converters with up to 192 kHz sample rate, at noise figures of 116 dBA.

SteadyClock(TM) guarantees optimal sound regardless of the quality of the external clock due to its efficient jitter suppression. The integrated Intelligent Clock Control not only clearly displays the current clock status, but also maintains the last input frequency recognized as valid in case of clock source failure. Technologies known and proven from other RME products, such as SyncCheck provide easy detection of error conditions.

All M-Series devices are fully remote controllable and configurable via MIDI. The entire state of the device, including the front panel displays, can be queried via MIDI. Each device can be assigned its own ID, which also allows separate remote control of multiple devices via only one MIDI channel. Thanks to an included software nothing stands in the way of easy-to-use remote control on Windows and Mac computers. At the same time MIDI data is transmitted via MADI (MIDI Extender).

The M-32 AD has a coaxial and optical MADI input. If one signal fails, automatic input switching immediately switches to the other input if a valid signal is present there.

Thanks to the four ADAT outputs, the M-32 AD can be connected to other studio equipment without any problems. An unbeatable combination results with RME's HDSPe RayDAT. This combo can transfer 32 channels simultaneously into the Mac or PC using inexpensive fiber optics, at an unbeatable price. The ADAT input of the M-32 AD is used in this context purely for optional external clocking of the converter.

All settings are saved on power-down.

The MADI input serves both as optional clock source and as loop-through input. Since the M-32 AD only occupies 32 channels in the MADI signal, the device loops through the unused channels of the signal present at the input. On this basis, serial cascading works, as the data of the device together with the input data is available as 64-channel MADI stream bundled in one line at the output of the last device. 

M-32 AD and M-16 AD can be freely combined up to the maximum of 64 channels: One M-32 AD with one or two M-16 AD is just as possible as up to four M-16 AD. Of course, the devices can be synchronized sample-accurately via word clock.

The number of channels that can be achieved with MADI depends on the sample frequency. At 48 kHz it is 64, at 96 kHz 32, at 192 kHz 16 channels. Thus, the M-32 AD at 192 kHz can only work as a 16-channel converter. 

The number of channels achievable with ADAT depends on the sample frequency. At 48 kHz it is 8, at 96 kHz 4, at 192 kHz 2 channels per port. Thus, the M-32 AD can output a maximum of 4 x 2 = 8 channels at 192 kHz via its four ADAT outputs.
