The BOSE's POWERSHARE PS620P is a 2-channel portable amplifier with an uneven distribution of its whole 600 watts across both outputs. Each output can have its own output level, EQ, and low-impedance/high-impedance (Low-Z/Hi-Z) settings. Total amplifier power is shared across all output channels thanks to unique technology, giving installers the flexibility to use power where they need it. PowerShare amplifiers adapt to a wide range of applications by supporting both low- and high-impedance loads up to 100V. In many setups, onboard customizable loudspeaker processing and direct access to zone controllers eliminate the need for an extra signal processor, while proprietary innovations inherited from the field-proven PowerMatch® range provide great audio performance and dependability.
