RME / M-32 DA Pro　MADI / AVB コンバーター

■ 32-channel high-end MADI/AVB converter

Advanced multi-purpose multi-channel format that combines the open standard network transmission standard "AVB" and the de facto standard "MADI" of point-to-point transmission, which has both flexibility and robustness. Reborn as a converter.

The compact 1U rack incorporates high-end components, including high-end converters, to deliver outstanding audio quality on all channels. Reflecting various feedback from the field, you can easily check the status of the equipment on the front channel and use the encoder and display to set all the installed functions. Custom labels with 32 green/yellow/red backlit LEDs display the signal level in real time, allowing you to instantly see the status of the unit even from a distance.

With the advent of the M-32 Pro series, such as a web server built into the main unit and an interface that allows easy remote control of devices, high-quality digital audio transmission via MADI/AVB that achieves both reliability and quality. You will be able to.
