Combining our decades of experience, expertise, and the flexibility of the unique Bose Modeler system, the professionals at Tree Ridge will design and install the best possible sound system for your venue.

Whether you deliver primarily voice, music, performance, sports, religious, or entertainment events, you want and need the best. Bose and Tree Ridge delivers exactly that, customized perfectly to fit your venue and requirements.

• Concert-quality sound – New Bose® patented technologies combine to provide audio quality equaling that of the best concert-sound systems, in a fixed-installation format

• RoomMatch™ waveguide technology – 5 vertical and 4 horizontal coverage pattern choices allow arrays to direct sound precisely to desired listening areas, improving audio quality by reducing unwanted acoustic reflections

• Progressive directivity arrays - A new class of curvilinear array in which the coverage and directivity index of each module is selected to optimize room coverage and system efficiency

• Continuous-arc diffraction-slot (CADS) manifold – Bose patented design provides interference-free acoustic summation of 6 compression drivers and acoustically equal spacing of diffraction slots across multiple modules

• Bose® EMB2 and LF10 drivers – Patented new Bose transducers combine to deliver the vocal clarity of 3-way systems with the improved polar response typical of 2-way systems

Building on the ruggedness proven by 20 years experience bulding Class D power amplifiers for the automotive market, the PM8500 adds numerous new Bose patented technologies to simultaneously provide class-leading power, efficiency, sound quality and reliability. The PM8500N adds Ethernet connectivity for network control and monitoring of multiple "N" version amplifiers using ControlSpace Designer.

• High degree of configurability – comes with a high level of performancel, optimizing frequency response while minimizing distortion.
• Better efficiency – by combining innovative fast-tracking Power Factor connection and four-quadrant operation without large transformers.
• Greater reliability – by using the planar magnetic transformer with a design adapted from the power supply industry. This transformer offers greater reliability and efficiency from a smaller design than conventional transformers.
