Controls: Operation of the AM/FM tuner can be done from the front-panel controls or the included wireless IR remote control. Controls on both include; numbered buttons for accessing the 20 station presets, Tuning +/- buttons, a Memory button for storing stations, Auto, Band, a Stereo/Mono button, and a Display button for accessing any RDS information. The wireless remote also includes buttons for PTY (Program Type Search) and APS. Pressing this button will have the tuner search and store available radio stations automatically, searching for RDS stations first, then others.
Outputs: The DN-300H includes a stereo pair of balanced XLR jacks and a pair of unbalanced RCA jacks for outputting the signal to an amplifier, mixing board, or receiver.
USB: A rear-panel USB (Type-A, 2.0) is provided for updating the firmware. An adjacent Normal/Update slide-switch is used for putting the tuner into firmware update mode. Note: The USB port if for updating only and does not support audio.
