The RME M-32 AD Pro II-D is a 32-channel high-end converter that seamlessly integrates exceptional analogue circuit design, cutting-edge converter chips, and RME's renowned SteadyClock technology, offering professional-grade AD conversion with features such as analogue 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 within a compact 2U rack unit.

Comprehensive Feature Set

The M-32 AD Pro II-D includes sophisticated features for professional studio, stage, and broadcast applications. It offers analogue limiters capable of handling up to 17 dB input overload without distortion (max. input level +30 dBu), ensuring reliable operation under demanding conditions. The converter supports three hardware reference levels, MADI and ADAT I/O up to 192 kHz, and provides 6.3 mm TRS and D-sub inputs.

Superior Performance and Reliability

This converter delivers multichannel conversion at reference quality, boasting an exceptional signal-to-noise ratio of 116 dBA across all channels. It utilises state-of-the-art converter technology. The balanced analogue inputs, derived from RME's ADI-8 QS design, maintain superior S/N and THD specs across various analogue levels.

Advanced Clocking Technology

RME's SteadyClock technology ensures optimal sound quality through effective jitter suppression, making the device independent of external clock signal quality. The Intelligent Clock Control feature monitors clock status, retaining the last valid sample rate in the event of an external clock failure. Additional RME technologies, such as SyncCheck, quickly detect clock issues.

Remote Control and Integration

The M-32 AD Pro II-D supports complete remote control and configuration via MIDI, with software available for both Mac and PC. Each unit's status, including all front panel displays, can be monitored and controlled remotely. The device's four ADAT outputs offer seamless connectivity with other studio equipment. When paired with RME's HDSPe RayDAT, it allows the transfer of 32 channels to a Mac or PC via optical Toslink cables, providing a highly efficient and cost-effective solution.

Enhanced Connectivity and Redundancy

Both the M-32 AD and M-16 AD models feature optical and coaxial MADI inputs, with automatic input switching in case of signal failure, ensuring continuous operation. The ADAT input also serves as an optional source for external synchronisation, further enhancing the unit's versatility and reliability in professional environments.
