Bose Professional PackLite Power Amplifier Model A1 PackLite Power Amplifier Model A1

The Bose PackLite Power Amplifier is a small, lightweight, powerful, and easy-to-use amplifier that interfaces quickly with the Bose® PS1 power stand and B1 bass modules to provide high bass output for demanding instruments such as bass guitar and drums.

The connections are quick and easy: plug in the AC cord, connect the A1 to the PS1 power stand, and play. When the A1 is used together with the Cylindrical Radiator® loudspeaker, no time-consuming adjustments are required. The components act as a system and automatically adjust bass output for more level and headroom, while maintaining consistent tone regardless of how many B1 bass modules are being used. In addition, the A1 can easily drive other passive loudspeakers such as bass guitar cabinets, subwoofers, studio monitors, and floor monitors
