■DAB+ Compatible Digital AM & FM Tuner

The Denon Professional DN-300DH is a globally compatible AM/FM/DAB+ radio tuner. Optimized for professional use, it delivers clear, uninterrupted radio reception while offering exceptional ease of use and versatility.

DAB+ is the latest digital audio broadcasting technology, characterized by crystal-clear sound quality and distortion-free operation. Digital audio broadcasting is far more efficient than analog broadcasting, resulting in more radio services, including pause and SD card storage. (As of 2018, this product is not available in Japan.)

You can automatically or manually tune in up to 40 channels, including RDS broadcasts. Balanced and unbalanced audio outputs enable versatile deployment, and a USB port allows for firmware updates that add or modify functionality. Display brightness and stereo/mono conversion are also available.
