Overview
DISCONTINUED
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.
- Records to SD/SDHC and USB media in MP3 and WAV (up to 24-bit/96kHz)
- Dual Record feature (records to two media options simultaneously for primary and backup recording)
- Dante™ 2 x 2 network interface for recording and playback
- Relay Record feature (continues recording to backup media when primary media is full)
- File Archiving via FTP (automatic or timed) with 24/7 record feature
- Web Remote for setup and control with password protection
