Bose Professional PowerShare PS404D Amplifier
The Bose Professional PowerShare PS404D is an adaptable four-channel power amplifier designed for professional audio installations. It features 400 watts of asymmetrically distributed power with integrated Dante support and advanced DSP for precise sound control in venues like conference centers and places of worship, supplied by Procure.ae.
The PS404D delivers 400W total power, distributable as four 100W symmetrical or 200W/800W asymmetrical outputs. It supports low-impedance (4–8 Ω) and high-impedance (70/100V) loads with a 100 dB dynamic range. Integrated Dante networking provides four audio input channels, allowing mixing with analog inputs via the 12-pin Euroblock connector.
Advanced ControlSpace Designer software enables configuration of matrix mixing, crossovers, limiters, and delay. Dual Feedback Loop technology monitors current and voltage for stability. The unit offers channel separation greater than 85 dB at 1 kHz and a frequency response of 20 Hz to 20 kHz (±0.5 dB) at 1W.
