Solid State Recorder
The DN-F450R offers a simplified, cost competitive solid state
recording and playback capability. Derived from the DN-F650R, the
half rack size unit provides for recording and playback to and from
SD and SDHC flash memory cards, with USB connectivity to PC for
file management and transfer. Balanced analogue inputs on XLR are
featured alongside unbalanced I/O.
Stereo and mono audio channels are simultaneously available, and PCM WAV and MP3 file
formats are supported, with the same sample rate and bit rate selectivity as the DN-F650R.
Serial and contact closure remote control are supported, and a headphone out with volume
control is included. Selectable playback modes, power on auto play, marking and mark
search, audible quick search, and easy file search with the front panel jog wheel are all
