Product Overview
This guide provides installation and operating information for Bose® PowerShare PS604A and PS404A amplifiers. Bose
PowerShare adaptable power amplifiers deliver 600 watts (PS604A) or 400 watts (PS404A) for fixed-install applications.
Through patented technology, total amplifier power is shared across all output channels, allowing installers the freedom
to utilize power where needed. With support for both low- and high-impedance loads up to 100V, PowerShare amplifiers
adapt to a wide range of applications. Onboard configurable loudspeaker processing and direct access to zone controllers
eliminate the need for an additional signal processor in many installations, while outstanding audio performance and
reliability are assured with patented technologies inherited from the field-proven PowerMatch® line. This unique set of
features and technologies makes PowerShare one of the most versatile high-performance amplifiers available.
Product Features
• PowerShare Technology
Patented PowerShare technology allows the total wattage to be shared asymmetrically across all outputs, as each output
is capable of delivering full power. Instead of selecting amplifier power based on the needs of the largest zone, installers
now have the freedom to use total amplifier power in the 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
Each channel can be configured for low-impedance (4-8 ) or high-impedance (70/100V) applications without bridging,
use of jumpers, or software settings.
• DFL
TM
System
The Dual Feedback Loop system, inherited from the field-proven Bose PowerMatch® amplifier line, improves performance
through 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.
• Integrated Loudspeaker Processing with Optional PowerShare Editor Configuration
For applications requiring additional signal processing, the PowerShare Editor software oers real-time selection and
control of Bose loudspeaker EQs, 9-band PEQs, matrix mixing, crossover, delay, and mute/output polarity through a USB
connection. For basic setups without a PC, rear-panel settings allow installers to recall Bose loudspeaker equalization and
protection per output channel. These features eliminate the need for an external signal processor in many applications.
• ControlCenter Zone Controller Accessories
Bose ControlCenter CC-1 zone controllers can be directly attached for remote adjustment of amplifier outputs, further
extending stand-alone amplifier applications.
• Auto-Standby
Designed to save power consumption when not in use. PowerShare amplifiers can be configured to automatically enter
standby mode when the audio signal falls below a set threshold, then wake when audio returns.
• PowerShare Amplifier Series
The PowerShare family consists of four 1U amplifiers: 2- and 4-channel fixed-install models, and one 2-channel portable
model.
