RME / M-32 AD Pro MADI/AVB Converter

32-Channel High-End MADI/AVB Converter

■32-channel high-end MADI/AVB converter

The new M-32 Pro combines the open standard network transmission standard ""AVB"" with the de facto standard for point-to-point transmission, ""MADI,"" to create an advanced, versatile, multi-channel format converter that combines flexibility and robustness.

The compact 1U rack is equipped with the highest level of components, including high-end converters, to provide outstanding audio quality on all channels. Reflecting various feedback from the field, the front panel allows you to easily check the status of the equipment and set all the functions using the encoder and display. 32 custom labels with green/yellow/red backlit LEDs display the signal level in real time, allowing you to instantly check the status of the unit even from a distance.

The M-32 Pro series features a built-in web server and an interface that allows you to easily control the equipment remotely, making it possible to transmit high-quality digital audio via MADI/AVB that is both reliable and high quality.
