RME / M-32 DA Pro 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, and robust multi-channel format converter.

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 functions using the encoder and display. 32 custom labels with green/yellow/red backlight 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 digital audio via MADI/AVB with high reliability and quality.
