Denon Pro Rackmount Network Audio Recorder DN-900R

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.

Features

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
