Used
but in excellent working and cosmetic condition (see photos). Fully tested, it has some small faint stains on the top which I tried to remove using household cleaner (SimpleGeeen), but I did not try anything more "aggressive."
Removed from a
corporate conference room environment where it had only occasional use. Both Euro-style input & output connectors are included. A brand new heavy-duty power cord is included, as are self-adhesive rubber feet if you wish to use this without the removable rack mounting brackets. Will also include the 1/8" (3.5mm) stereo input cable shown in the pictures that was used to test this with. Very
well packed for safe shipping; will use lowest-cost method which you select.
Manufacturer Description
The Bose AmPlus 100 business music amplifier is a 100 watt amplifier that satisfies a wide variety of applications in the commercial and consumer marketplace. The AmPlus 100 amplifier is a 2-channel, multipurpose amplifier used in powering 4Ω, 8Ω, 25V or 100V loudspeakers. The AmPlus 100 business music amplifier has front end processing permitting the connection and level adjustment of two sources: left/right or source A/source B. Power hookup, remote volume hookup, line output connections, and provision for bass adjustment are provided on the rear panel.
