Denon DN-333XAB Mixer Amplifier (Bluetooth-Enabled)

The Bluetooth®-enabled DN-333XAB forms the heart of a complete commercial audio system by mixing and amplifying wireless, microphone and line input sources. This rackmount mic/line mixer with integrated amplifier is ideal for the education, fitness, restaurant and hospitality markets.

Perfect for driving in-ceiling or wall-mounted speaker systems, the DN-333XAB features 120 watts of built-in Class D amplification at ultra-low distortion for exceptional clarity. Dedicated mixing controls for three XLR+1/4-inch combination microphone inputs, two pairs of stereo line level RCA jack inputs, and a front-panel 1/8-inch (3.5mm) auxiliary input gives users the ability to create a seamless blend of audio from a plethora of source types. A front-panel Bluetooth pairing control with LED status indicator provides a fast and simple wireless connection to smartphones and tablets. A quick-responding limiter eliminates the negative audible effects of excessively high input signals from microphones or playback material.

The DN-333XAB output section offers detachable Euroblock 70V and 100V outputs with a 4-ohm transformer bypass output, as well as Chime, Alarm, and Mic 1 priority facilities. An RCA line-level send and return connector lets the installer integrate external audio processors, if desired. The compact 2RU unit fits neatly with other rack-mounted equipment for an integrated system appearance, or may sit on a shelf via the attached rubberized feet.

More than ever before, commercial installations require utmost flexibility without compromising sound quality or increasing complication. That’s why we developed the DN-333XAB. It fuses comprehensive source mixing and simple, intuitive operation with professional amplification, in a compact and affordable package that works with virtually every mobile device imaginable.
