Denon’s newest content players, the DNF300 and DN-F400, use SD and SDHC cards for source media. Without moving parts these players should prove more reliable, quieter, cheaper to operate (no prerecorded CDs to buy or keep track of) and durable.
The rackmountable players read MP3 and WAV files. The DN-F300 has a USB drive as well for media along with a remote control and a microphone for announcements. For the microphone a ducking function is included as well as a +/- 12 percent pitch control.
