This Denon Retail Sound System is perfect for a variety of applications such as classrooms, conference rooms, retail stores and restaurants. This complete audio package consists of one Pure Resonance SD4 Ceiling Speaker Array and one Denon DN200AZB Bluetooth Receiver with Zone Amplifier.

The SD Speaker employs (4 smaller 6.5”) very fast transient response aluminum-woofer drivers that are very powerful and stable. Working in unison these drivers produce clean powerful dynamic sound. When designing the SD the goal was to have the single most import feature at the forefront, good transient response ("dynamic contrast"). A transient is a sound of short duration, and good transient response can only be achieved if the speaker can deliver its output quickly and cleanly without smearing the original sound, and be completely soundless immediately after. Transients contain the essentials of sound reproduction they provide the sharp pop from a snare drum, the cutting edge of digital sound, the dynamics of the human voice. Larger 2-way cabinet loudspeaker systems offer relatively slow transient response, and the small high-frequency horn tends to beam a narrow, blaring sound at the listener—end result, muddy sound. By replacing larger speakers with four 6 or 8" drivers we increased the driver surface area while creating more punch and a tight, more focused low-end.

The Denon DN­200AZB receives Bluetooth audio content and powers local speakers with its built­in 70V/100V digital Class D amplifier. The interface is perfect for restaurants, behind bars, at display kiosks, and anyplace where having bulky and complicated signal­producing equipment is not feasible. Simply stream audio wirelessly from any Bluetooth enabled smartphone, tablet, or computer and the 200AZB receives it and powers connected speakers—a neat and uncomplicated answer for the Bring Your Own Device revolution.
