PRODUCT DESCRIPTION
The Bose
®
PowerShare PS404A and PS604A adaptable power ampliers deliver 400 and 600 watts,
respectively, for xed-install applications. Through patented technology, total amplier 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 ampliers adapt to a wide range
of applications. Onboard congurable 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 eld-proven
PowerMatch
®
line. With the inclusion of AmpLink, up to 24 digital audio channels can be sent to the
amp from a Bose DSP via a shielded CAT 5 cable. This unique set of features and technologies makes
PowerShare one of the most versatile high-performance ampliers available.
Key Features
• PowerShare Technology – Patented PowerShare technology allows the total 400 or 600 watts of power
to be shared asymmetrically across all outputs, as each output is capable of delivering full power. Instead
of selecting amplier powerbased on the needs of the largest zone, installers now have the freedom to
use total amplier power in the application. This enables more exibility 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 congured for low-impedance (4-8 Ω) or high-
impedance (70/100V) applications without bridging, use of jumpers, or software settings.
• DFL™ System – The Dual Feedback Loop system, inherited from the eld-proven Bose PowerMatch
amplier line, improves performance and reliabilitythrough 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 EditorConguration – For applications
requiring additional signal processing the PowerShare Editor Software offers 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 equalizationand protection per output channel. These features eliminate the
need for an external signal processor in many applications.
• AmpLink – Transports up to 24 uncompressed, near zero latency, digital audio channels between Bose
DSPs and the PowerShare PS404A via shielded CAT 5 cable. The amp also supports a THRU path for
daisychaining up to 8 other Bose AmpLink ampliers, at a distance of up to 10 m between products. Any
combination of AmpLink ampliers can be daisychained.
• ControlCenter Zone ControllerAccessories – Bose ControlCenter CC-1zone controllers can be directly
attached for remote adjustment of amplier outputs, further extending stand-alone amplier applications.
• Auto-Standby – Designed to savepower consumption when not in use.PowerShare ampliers can be
congured to automatically enter standby mode when the audio signal falls below a set threshold, then
wake when audio returns.
