DN-900R

Network SD/USB Audio Recorder with Dante 2 x 2 Interface


Taking its place as Denon Professional’s flagship recording product, the DN-900R Dante/Network SD/USB Recorder is designed to meet the needs of the most demanding installations, combining high-quality audio recording with extensive network capabilities. With a powerful feature set and using the most reliable solid-state recording media, the DN-900R enables AV installation professionals to replace traditional recording devices with superior solid-state hardware in the widest range of applications.

Housed in a compact 1U rack-mountable chassis, the DN-900R offers Dante 2-in/2-out network compatibility as well as recording to both reliable SD card (two slots, 32GB ea.) and USB storage media. The unit can be configured for ‘dual’ simultaneous recording to both formats or ‘relay/cascade’ recording where longer recording times are desirable.

Designed for professional environments, the DN-900R features versatile connectivity including balanced XLR analog audio and AES/EBU digital I/O, as well as unbalanced analog connections and SPDIF.
