Bose Professional have expanded its PowerMatch amplifier platform with three additional models of configurable power amplifiers – the PM8250, PM4500 and PM4250. The Class-D amplifiers and power supplies are designed to cope with unexpected variations in AC line voltage, rack temperature, and output load conditions. Configurable through the use of QuadBridge™ technology, each amplifier is capable of combining 2 or 4 output channels, creating flexible options to drive different power levels and loudspeaker impedances.
The full PowerMatch® amplifier line now includes 8 models, including networkable which enable control and monitoring over standard Ethernet networks. All models are housed in a 2U chassis and require standard AC circuits. All models include onboard loudspeaker DSP, support for both low and high impedance loads (without external transformers), front-panel user interface, and fault detection, plus a digital expansion slot for use with optional audio networking and Bose ESPLink cards. PowerMatch amplifiers are put through Bose’s rigorous quality testing procedures and are backed by a 5-year warranty. The PM8250, PM4500 and PM4250 will be available from June 2013.
