The Bose

PM8500(N), PM8250(N), PM4500(N) and PM4250(N) amplifiers are
configurable professional audio amplifiers. There are eight PowerMatch amplifier versions in
total. The differences are related to channel count, power output levels and networked or non-
networked versions. There are two versions in each category, i.e. PM8500 and PM8500N, which
are identical except that the network capable (N) version adds an RJ45 connector on the rear
panel to allow network control and monitoring of multiple units, using Bose ControlSpace
®
software and standard Ethernet network equipment. This is also true of the PM8250(N),
PM4500(N) and PM4250(N) amplifiers in the product family.
