Plena Matrix – Up to eight zoned, commercial sound and public address system with wireless control
Flexible and powerful, the advanced features of the Plena Matrix Digital Sound System enable users to achieve superb audio performance with wireless control across up to eight output zones. With audio quality tailored for a wide range of applications — including live music, business music, high-demand speech environments and zone announcement — the Plena Matrix system delivers full featured digital audio control, with maximum flexibility and reliability.
Specially designed for versatility and ease of use, the Plena Matrix system enables users to control the audio settings and adjust volume levels wirelessly via an iPad or iPhone app.
The PLM 8M8 Plena matrix 8-channel DSP Matrix Processor, the heart and soul of the Plena Matrix System, provides complete control over the audio configuration and signal processing. Users can simply walk into a particular zone and confidently match the audio quality to specific requirements — from live and background music to high demand speech environments. The Plena matrix Class D Power Amplifiers feature an Auto Standby mode that — when activated by Bosch motion sensors in output zones that are unoccupied — helps to generate cost savings of up to 80% as compared with standard amplifiers. And by reducing overall power consumption, the environmental impact is significantly reduced.
