Native support of Apple iDevices is included with "Airplay" compatibility, providing users with one-click content access via iPod, iPhone or iPad. FLAC, WAV, AIFF and other lossless audio files can be played back at full quality, with 24-bit/192kHz digital-to-analog conversion included for maximizing the quality of "lossy" content types. A front-panel USB port is provided for direct connectivity of flash and external hard drives, in addition to other Mp3 players and smartphones. Users without subscriptions to internet radio services like Pandora, Napster and Sirius XM can access local airwaves via the DNP-720AE's built-in AM/FM radio tuner, all configurable on the unit's multi-level OLED display. In addition to the unit's hardware remote control, Apple iDevice users can download the free Denon Remote App for full touchscreen operation. A two-year manufacturer warranty is included with purchase.
