Denon's DN-300Z rackmount CD / SD / USB / Bluetooth / AM / FM Media Player provides virtually any kind of playback capability you may need in your next system install or upgrade. Balanced and unbalanced audio outputs make it easy to integrate into any system, and there is even a 3.5 mm AUX in for portable media devices. Simple to operate, you’ll find the purity of its audio performance is truly remarkable at its modest price point - giving you a rugged, no-compromise playback solution that occupies a mere 1U of space. An IR remote is included.

It really does expect the unexpected. Go ahead, throw anything you want at it: front-loading media slots (CD w/single-play mode, USB, SD/SDHC) deliver intuitive playback of today’s familiar mass-storage mediums. Or, go wireless with long-range Bluetooth audio connectivity (up to 100 feet) and instant recall of up to 8 devices such as smartphones and tablets. With support for CD-DA, MP3, WAV, and AAC file formats, the DN-300Z is the master-of-all-trades player that excels when the unpredictable occurs. The 300Z features both RCA audio outputs and balanced XLR outputs. The balanced outputs are a much-needed feature in the professional/commercial sector, since they enable long connection cable runs without any increase in stray noise pickup. The selectable Power-On-Play mode automatically plays USB, SD or CD tracks when powered up — simply turn it on. And, the AM/FM tuner has a dedicated audio out for multi-zone use.

The front panel's backlit LCD screen provides at-a-glance status of playback modes and content, providing clear readouts to even the most novice user. Designed to adapt to any scenario, switching formats on the fly has never been easier. Media categories and their respective controls are grouped together so users will never have to wrestle with deep menus or use the instruction manual to perform basic functions. Direct access to CD tracks, global transport controls (play/pause/search), and a rotary-push encoder translate to fast, hands-on command when you need to get to your content.

An IEC-weighted AC power port means space-saving connection to power sources—no bulky transformers or “wall warts” required. When installed into a client’s rack, the DN-300Z provides the capability, reliability, and versatility to tackle any playback task, from one-off requests to rehearsed program material, in an intuitive, tidy package.

The DN-300Z media player expects the unexpected. But you demand it.

Audio distribution systems, especially those commonly used in department stores, warehouses, restaurants, etc., require that many loudspeakers be driven from a single audio amplifier over long runs of speaker wire. The "constant voltage" or "high impedance distribution" audio systems can be complex to understand at first, however, provides many advantages. Learn how to design your own 70-volt or 25-volt loudspeaker system.
