Bose insists on flexible power sharing

Published:

Designed for portable and installed applications, Bose has expanded its F1 Flexible Array loudspeaker product line to include a new passive full-range model and a full suite of mounting brackets.

Weighing 21.3kg, the F1 is the first loudspeaker series offering Flex array technology, whereby the audio can be targeted to listening areas with four different patterns. The new cabinet hosts eight 2.25-inch drivers, 100-degree horizontal waveguides, a 12-inch woofer and a lower crossover point. The F1 Model 812 housing comes with M8 top and rear hang points plus three dedicated brackets for easy and flexible mounting, whilst pan and tilt, yoke and U bracket options are available. When combined with the 1,000W-rated Bose F1 active subwoofer, a mounting stand with cable channels allows the active loudspeaker model to be integrated into the body of the subwoofer.

Moving from speakers to amps, the PowerShare adaptable power amplifier series currently consists of two- and four-channel fixed-install models (PS602 and PS604) as well as a two-channel portable version (PS602P). Each 1U model delivers 600W of power that can reportedly be shared across all output channels with support for both low and high-impedance loads up to 100V. Whilst integrated DSP provides direct access to zone controllers, PowerShare technology is stated to ensure asymmetrical sharing of total amplifier power across outputs with flexibility to use total amplifier power in the application.

Inherited from the PowerMatch series, PowerShare amplifiers employ the Dual Feedback Loop (DFL) system, which continuously monitors and controls both the current and voltage delivered to each output load. This combination provides improved linearity and lower distortion, while providing loudspeaker protection, promises Bose. Furthermore, each channel can be adopted for low-impedance (4/8-ohms) as well as 70/100V applications without bridging or software settings.

For applications requiring additional signal processing, PowerShare Editor software offers realtime selection and control of Bose loudspeaker EQs, nine-band PEQs, mixing, crossover, limiters, delay and mute/output polarity through a USB connection.
