The Denon Professional DN-500R SD and USB Recorder is a 1U rack mountable recorder and audio playback device designed for installed sound applications such as houses of worship, education, and more. The unit can record to both SD/SDHC cards and USB media either one at a time for longer recording times or simultaneously to both mediums for backup.

A shift button changes these buttons to functions such as dimming the display, marking files, record monitoring, switching to frame mode, and adjusting pitch. A rotary knob button controls recording level, recording balance, and navigates the menu settings. The front of the unit has an SD/SDHC card slot for inserting recording media with ejection button, as well as a USB female type A port for plugging in USB media such as thumb drives and external USB hard drives. A second USB female type A port allows you to plug in a USB QWERTY keyboard for entering file information while recording. The unit also includes a 1/4" headphone out and headphone level control knob for monitoring while recording or listening to recorded tracks.
