Bose PowerShare PS404D Adaptable Power Amplifier

PowerShare technology: Distribute the total 400 watts asymmetrically across all outputs using patented PowerShare technology, which allows each output to deliver full power. Instead of selecting amplifier power based on the needs of the largest zone, you now have the freedom to use total amplifier power in any application. This enables more flexibility during the initial design, or later on-site when making unplanned changes that take advantage of surplus power.

Load-independent outputs: Configure any channel for low-impedance (4-8 ohms) or high-impedance (70/100V) applications without bridging or using jumpers.
