Multimedia signage used to mean three things - poor quality, hard to use, and worst of all, unreliable. Now, Denon Professional reinvents the world of multimedia signage with the DN-V755 Network Audio/Visual Players.
Applications from theme parks to convention centers, from museums to malls, from airports to education, and many others will vastly improve the quality and effectiveness of their digital signage, while simultaneously making it easier to use.
Digital Quality
Older systems played fuzzy VHS tapes, which suffered from clarity and tracking problems or involved expensive and cumbersome PC/software based solutions. The DN-V755 MPEG-2 video files at up-to and beyond DVD quality. Traditional audio playback came in the form of cassettes or low-bandwidth digital audio, which usually ended up sounding like a telephone, or like there was a pillow in front of the speaker. The DN-V755 offers MPEG-1 (layer II) audio playback, and even uncompressed 16-bit PCM playback from .Wav files. Still pictures, such as i-pictures, can be easily uploaded for signage or presentation.
Extensive Capacity
The internal hard disk drive of the DN-V755 can hold up to eight hours of DVD quality video. Lower bitrates can be used to extend video time. Alternatively, thousands of photographs or graphics, and hours of CD-quality audio, or any combination of the above can be stored. Files for multiple presentations can be stored, and script files will instruct the DN-V755 on what to play, and when to play it. If your storage needs are greater than that, you can more than triple the storage capacity by upgrading to an internal 137 GB hard drive.
Control and Programmability
Designed for both ease of use, and flexibility, the DN-V755 offers multiple options for control. In addition to front panel controls, customized control surfaces can be easily created with the parallel connection. This 15-pin D-Sub connector offers switch-closure control of major functions. A 9-pin RS-232C serial port allows standardized serial control.
Media Transfer
The DN-V755 eliminates the laborious process of real-time recording or even transfer of files from media cards. Uploading MPEG video, .wav files and other media directly from your computer is accomplished via the DN-V755's built-in LAN port. An easy-to-use Windows application makes selecting and transferring your files a breeze.
Play Logs
The DN-V755 can keep a record of the time and date each file is played. For systems integrating safety announcements or paid advertising, play logs can serve as proof of performance.
