1RU Slot-in Network CD Player

DN-C640

Introduction
In our world of multifunctional electronics, it seems there is no combination of digital functions that hasnt been marketed. The key, of course, is meeting peoples needs. So we have a camera on a cellphone, a game console with a media player, etc. The key to dening an objects basic nature is its form factor. The new DN-C640 from Denon Professional is, at the heart of it, a full-featured, rack-mounted network CD player. But note the word Professional in the brand name. With a combination of exible le formats, network control, and comprehensive inputs and outputs, this machine takes the CD player concept to new heights.
server or computer, as long as it is accessible via a network. Now, any corporate environment that records and stores their meetings on a network HDD or computer can simply navigate to that folder location from the front panel of the unit or by using the on-board web browser, select a specific file, and play it into their system. Any application from background music, to meeting recording playback, to small radio stations not utilizing some sort of enterprise software to manage their station will benefit greatly from this unique feature.
Controllability for Every Application
The new Denon Professional DN-C640 comes with a host of control options, suitable for every application and every installation. 25-pin Contact Closure (GPIO) Denon CD players have been used for years in the broadcast market and the DN-C640 is no exception. A 25-pin GPIO port allows for easy integration and full-featured usability in every broadcast studio or station installation. 9-pin RS-232C Control The DN-C640 easily integrates into any new or existing installation using third-party serial control systems like Crestron or AMX. IR Control with included IR Remote Control Like most CD players, the DN-C640 is controllable by its included IR commander. Perfect for small installations not using serial control solutions or Health and Fitness centers, the IR control allows every feature from playback to the +/-12% pitch control to be activated/ adjusted. Internal WEB GUI for Control from any Web-enabled Computer It is becoming standard in our industry that any network device be controllable via a web-enabled computer. Because the machine has its own web server on-board, any computer on the same network can call up and play audio les, build program playlists, and have full transport control functionality over the DN-C640.

Reads CD-R/RW, DVD-R/RW, and DVD+R/RW discs
For several years now, newer CD Players expanded the length of continuous playback time without interruption by adding the ability to play back compressed digital audio files off CD data discs. One CD data disc could provide as much as 20 hours when playing back low bit rate MP3 files. The DN-C640 embraces this idea but takes it a step further. Not only can the DN-C640 playback MP3 and WMA files from CD DATA discs, but it is also capable of decoding broadcast standard MP2 and uncompressed digital PCM (WAV) files from those same discs. In addition to reading all of those files from CD, it also has the unmatched ability to read any of the above from any DATA DVD. This not only expands the 20 hour playback time to almost 3 days of continuous playback (999 files at 4 Min. each), but also allows those users who demand uncompressed audio quality the ability to playback full 44.1kHz PCM recordings without being limited to the 80 minute CD-R.

Plays Back Digital Audio Existing on Other Network Devices
Not only can the DN-C640 decode a host of compressed and uncompressed digital audio files from CD or DVD data discs, but it now gives the end-user the unique ability to stream any of those files from a
