This Power Dynamics 2-Zone Bluetooth audio system includes a 240 W matrix amplifier and 12 white ceiling speakers, designed for flexible multi-room audio distribution. The amplifier offers independent zone control, allowing different audio sources and volume levels in each zone simultaneously. One zone can play from connected devices such as CD players or computers, while the other streams music via Bluetooth from smartphones or tablets. The 100 V system architecture eliminates signal loss over long cable runs and simplifies installation compared to conventional systems. The amplifier features built-in USB/SD MP3 playback, multiple microphone and line inputs, an XLR microphone input with phantom power, bass and treble control per zone, and remote control functionality. It delivers 2x120 W power with a frequency response of 100 Hz-24 kHz and measures 390x385x95 mm with a weight of 14 kg. Each of the 12 included ceiling speakers has a 13.3 cm woofer and a 1.27 cm tweeter in a coaxial design, delivers 20 W power with a frequency response of 70 Hz-20 kHz and 88 dB sensitivity. The flat speakers install discreetly with a 74 mm installation depth and a 161 mm cutout diameter and feature magnetic steel grilles for a clean appearance. The system includes 100 meters of double-insulated 100 V speaker cable for immediate installation. With rack-mount compatibility and backup power via an external 24 V battery, this professional audio solution supports expansions beyond the included 12 speakers while ensuring reliable performance in distributed audio environments.
