Redundant power supplies, more compact housings, network functionality - these and other wishes were brought to us by our customers for a revised 32-channel converter series. With the new M-32 DA Pro and M-32 AD Pro, RME meets the diverse requirements of current productions and installations.

Reference in analog and digital

Based on state-of-the-art, high-resolution converter components and a fully balanced analog circuit design, the new M series offers a signal-to-noise ratio of 120 dB(A) with shallow THD values, which places the converters in the reference class.

Linear and transparent

Each of the 32 channels enables AD/DA conversion with up to 192 kHz sampling frequency. The internal filters are based on the recently introduced ADI-2 Pro reference converter and allow a completely linear frequency response (up to 0 Hz at the output).

AVB - The future of network signal transmission

In addition to the two fully equipped MADI I/Os including separate signal routing, the new M-32 DA Pro and M-32 AD Pro feature an AVB interface based on the open network standards IEEE 802.1 and 1722.1, enabling transmission of the 32 analog channels at a maximum 192 kHz sampling rate via a single Ethernet cable. Combined with external AVB switches, the new M-Series converters can be quickly, easily and reliably integrated into more complex network structures thanks to the comprehensive time-synchronous signal processing of the AVB protocol. Up to 128 audio channels can be sent and received over AVB in total across all streams.

Seamless integration

The open AVDECC 1722.1 control protocol as part of AVB allows users to use external controllers from different manufacturers to control almost all device functions. In addition, a web interface and a JSON API are available - both via the network connection and the integrated USB port.

With the latest Firmware 2.0.0 Update, the M-32 Pro Series is now fully remote controllable via a web interface on any network link (including wirelessly over Wi-Fi), with the same intuitive user experience as on all other AVB devices known from RME Audio.

Worldwide compatibility

For maximum compatibility with a variety of analog hardware, the individual channels of the M-32 AD Pro and M-32 DA Pro 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.
