Bose Professional PowerShare PS404D Adaptable Power Amplifier

The Bose PowerShare PS404D sets a new standard for fixed-install applications. This 400-watt amplifier boasts patented technology that shares its total power across all of its output channels, enabling installers the freedom to utilize power where it’s needed. This flexible power amplifier supports both low- and high-impedance operation, making it suitable for a wide range of applications. Benefit from top-shelf sound and rock-solid performance, thanks to Bose’s field-proven Dual Feedback Loop system, while integrated DSP via ControlSpace Designer software gives you studio-quality sound without the need for external processing. ControlSpace Designer also allows for mixing onboard analog inputs with digital inputs from a Dante network, thus enabling inclusion into large, networked audio systems. An Auto-Standby feature rounds out the PowerShare PS404D’s impressive features.

FEATURES

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 Ω) or high-impedance (70/100V) applications without bridging or using jumpers.

Integrated Dante Audio Networking
Support four audio input channels from a Dante network and mix onboard analog inputs with digital Dante inputs as selected in ControlSpace Designer software.

Dual Feedback Loop System
Improve performance and reliability. The Dual Feedback Loop system, inherited from the field-proven Bose PowerMatch amplifier line, allows for continuous monitoring and control of both the current and voltage delivered to each output load. This combination provides improved linearity and lower distortion while protecting loudspeakers.
ControlSpace Networking
Configure using ControlSpace Designer software for inclusion into larger networked audio systems where end-user controllers and scheduling events can control amplifier parameters.

Integrated Loudspeaker Processing
Adjust various parameters using ControlSpace Designer software: nine-band PEQs, matrix mixing, crossover, limiters, delay, mute/output polarity, and more.

Auto-standby
Save power — PowerShare amplifiers can be configured to automatically enter standby mode when the audio signal falls below a set threshold, then wake when audio returns.
