Overview
Overview
Put the power where you need it. PowerShare amplifiers deliver outstanding audio performance and reliability
with patented technologies inherited from the field-proven PowerMatch line — now with added flexibility.
Using innovative technology, the PowerShare PS604D (PS404D) shares power across all output channels
and delivers 600 (400) watts for installed applications. This means you can distribute the total 600 (400)
watts asymmetrically across all outputs or use any individual output to deliver full power. And with support
for both low- and high-impedance loads up to 100V, it’s easy to adapt PowerShare amplifiers to a wide
range of applications. ControlSpace Designer software allows for Ethernet-based configuration and quick
setup of external control options. With onboard Dante® audio networking, you have the flexibility to place
PowerShare amplifiers away from source locations and closer to loudspeakers. This unique set of features and
technologies makes PowerShare one of the most versatile, high-performance amplifiers available today.
Product Features
PowerShare Technology
Distribute the total 600 (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.
