Bose PowerShare PS404D Adaptable Power Amplifier – EU

Bose Professional PowerShare PS404D Adaptable Power Amplifier 230V EU

The Bose Professional PowerShare PS404D 230V EU is a multichannel adaptable amplifier designed for installed audio systems that need flexible power distribution, digital and analog connectivity, and integrated loudspeaker processing. The amplifier provides 4 × 100 W, allowing system designers to allocate output according to connected loudspeaker requirements. It supports low-impedance and distributed-voltage applications, helping one amplifier platform serve a range of commercial sound configurations. Four balanced analog inputs and four Dante digital inputs provide flexible source connectivity. Integrated DSP includes matrix mixing, loudspeaker EQ, real-time parametric equalization, voltage limiting, delay, band-pass filtering, mute, and output-polarity functions, allowing detailed system configuration without separate processing hardware. The 1RU rack chassis uses variable-speed cooling and standard professional connectors for practical installation. The 230V EU version is configured for its regional mains requirement and is suited to commercial venues, installed entertainment systems, paging systems, and distributed loudspeaker applications where centralized processing and efficient rack utilization are important. The European 230 V configuration is suited to compatible fixed-installation power systems. The platform is intended to provide predictable performance and straightforward integration when matched with compatible system components. Correct installation, loudspeaker matching, and system configuration help maintain the intended acoustic performance across the coverage area. Its practical combination of connectivity, processing, and installation features supports consistent operation in appropriately designed commercial sound systems. The platform is intended to provide predictable performance and straightforward integration when matched with compatible system components. Correct installation, loudspeaker matching, and system configuration help maintain the intended acoustic performance across the coverage area.
