RME M-32 AD Pro II-D High-End 32-Channel 192 kHz AD Converter with MADI and Dante

The M-32 Pro II series is designed to meet the demanding requirements of professional studios, immersive sound installations, live sound systems, and industrial applications that need a reliable solution for analog conversion with high-end network audio processing. These new converters are available with either 32 analog inputs or outputs, and either with Dante® or AVB for a choice of four different models.

Boasting up to 32-channels, fully equipped MADI I/Os (coaxial & optical via optional SPF module), improved specs with extremely low THD values, intelligent channel routing and innovative usability, the brand-new M-32 Pro II Series truly represents the state-of-the art in exceptional audio performance.

The Ultimate Solution for High-End Network Audio Processing
The latest 32-channel M-32 Pro II is based on state-of-the-art, high-resolution converter components and a fully balanced analog circuit design that offer signal-to-noise ratios of 120 dB(A) with very low latencies - placing the converters in the reference class. While the M-32 AD Pro II offers the same outstanding analog performance as its predecessor, the DA-Converter has even improved the THD+N to -111 dB. All models benefit from impulse response optimization at sampling rates of 88.2 kHz and higher to minimize ringing artifacts in the conversion process.

Plug & play - rapid user interaction
Control all device states directly from the front panel for convenient, direct access to all features. RME network audio devices can be reached over network (including wirelessly over Wi-Fi) and USB for convenient remote access, allowing the rapid creation of gain groups, phantom power switching and clock configuration. In addition, a JSON based API and even SysEx MIDI commands can be used to integrate each model virtually anywhere. The integrated routing matrix allows single channel routing across all analog and digital I/O. As such, problem-solving of signals, clocking, connectivity or other issues is both simple and straight-forward!

Dante Audio Networking - 2 fully redundant network ports
With an ever changing landscape of network audio solutions, the challenge for RME’s development team was to design a highly performant device platform that will guarantee unparalleled flexibility and stability for years to come. To match these high requirements in accordance with RME’s core principles everything was built from the ground up. By integrating Audinate’s Dante IP Core on a custom built RME FPGA platform, RME is not only delivering a highly flexible solution but also gets one step closer to achieving a truly universal Audio Networking experience.

Dante connectivity was a frequent request and has been integrated to run natively on the M-32 Pro II-D hardware. It provides direct connectivity to other audio devices via standard switches – and allows users to directly record and play back up to 64 channels from their computer to any of the M-32’s analog and digital I/O using Audinate’s Dante Virtual Soundcard™ (License not included)

Analog Line Level Performance
For maximum compatibility with a variety of analog hardware, the individual channels of the M-32 AD Pro II and M-32 DA Pro II can be operated with different line levels - each with full resolution of the converters. Besides +19 dBu and +13 dBu, the new M-Series is one of the few solutions available on the market that also allows working with the SMPTE® recommendation of +24 dBu at 0 dBFS.

Easy to Operate
Tri-color back-lit channel label fields offer an almost indispensable advantage in fixed installations. Using the provided transparent papers, users can create individual channel labels and securely affix them behind a magnetic cover, where they are illuminated depending on signal level. This provides a comprehensive overview of analog channel assignments and signal flow.

Updates included
With hardware built to last, RME makes sure the firmware running on the device does not fall behind. Since the release of the first version of the M-32 Pro, numerous feature updates have been released, delivering an increase of AVB total stream and channel count from four streams (64 channels) to nine streams (128 channels + additional CRF clock stream), additional stream formats, numerous adjustments for MILAN™ compatibility, single channel routing, preset upload and download, configurable preset names, static IP address assignment, and many more. They reflect the ongoing commitment of RME developers to sound engineers that expect the best performance of their devices for years to last.
