DENON MEDIA PLAYERS - Solid state
Denon media players are intended for use as a source of music, installed in venues such as bars, restaurants, offices, fitness studios and houses of worship. Stereo or mono MP3 or WAV audio files can be played from a removable SD or SDHC card or from external USB media. Infra-red remote controls are included, so the players can be operated from a distance of up to 10metres as an alternative to the controls on the front panel.
In addition to MP3 and WAV, playback a microphone may be connected for paging or announcements. A simple file-management system allows the operator to select the file(s) to be played, and to enable other functions such as repeat and random play, pitch-shift with or without constant tempo and fast re-cueing. It is also possible to repeat a section of programme within an individual track. The player has front and rear microphone inputs, and music-ducking under announcements can be enabled if required. An auto-play feature puts the DN-F300 into play mode from power-up, making it suitable for use in retail premises, galleries and similar locations.
The front panel has a large multi-function display; information includes elapsed or remaining track-time, track or file-name, folder and track numbers, play-back mode, pitch percentage, and track BPM. The memory-card slot and USB port for use with flash memory (SD or SDHC Flash memory cards, maximum capacity 32GB) or an external hard-drive, with associated select buttons, are adjacent. There are dedicated keys for 'Play/Pause', 'Stop', 'Cue', 'FFWD' and 'FREW'. File or track selection, folder navigation and menu operations are performed with a rotary jog-wheel with push-to-enter function. A 'display' button selects the text display to show MP3 folder, track, artist or album names from ID3 tags, accesses menu-mode and has a 'store' function within the menus. Temporary pitch-bending can also be achieved with dedicated '+' and '-' buttons. The front panel also has two 6.35mm 2-pole jack sockets for an unbalanced microphone input and a headphone output. Both sockets have associated level controls, and there is also an output level control. All level controls retract flush into the panel when not in use.
The rear panel has two RCA (phono) sockets for unbalanced audio outputs and a 6.35mm 2-pole jack socket for a second unbalanced microphone input; this input is summed with that connected at the front panel. DC power input is via a coaxial socket from an external AC adapter.
Playback file formats: MP3: Stereo or mono, 44.1kHz, 16-bit, 14 bit rates from 32kbps to 320kbps, plus variable (VBR); WAV: Stereo or mono, 44.1kHz, 16-bit.

The DN-F350 has much of the functionality of the DN-F300; in addition it can connect to external devices via Bluetooth for audio playback. Where the DN-F300 has two microphone inputs, one on the rear and one on the front panel, the DN-F350 offers a single combination socket, XLR plus 6.35mm jack, for microphone or line input. The XLR can be supplied with +48V phantom power may be switched for microphones requiring it. The signal from this socket does not pass to the headphone output, but can be routed through the main balanced XLR and unbalanced RCA phono outputs on the rear of the unit. An auto ducking function can be used to reduce the volume of the audio source when an input signal on the microphone channel is sensed.
The front panel also gives access to USB socket, SD card slot, 6.35mm headphone socket and a host of transport buttons, rotary controllers and switches. Audio files including MP3, WAV, FLAC, MP2, M4A, WMA, AIFF can be played directly from a USB device or SD card by using the included infrared remote control or transport section on the front panel. A rotary control for 'pitch/tempo' alters playback by +/-15% pitch or tempo, with a pitch/tempo selection toggle button allowing access to either of the adjustments. The 'pitch/tempo' adjustment is applicable to SD, AUX, USB, Bluetooth and mic/line inputs. Alternatively the user can operate pitch bend or tempo temporarily by using 'Pitch Bend' plus and minus buttons.
A single IEC mains AC power input (110 to 240V, 50 to 60Hz) can be found on the rear panel along with balanced and unbalanced outputs, Bluetooth receiver, and second USB input with switch. This USB input can be set to 'normal' to allow connection to an external USB drive for audio playback, or to 'update' when a connection is required to update firmware.
