The BP-200 bass amplifier from Phil Jones Bass redefines tone in a no compromise, high-performance 200-watt design that can fit into a backpack. Ideal for the gigging, studio and practicing bassist on the go, the BP-200 is packed with the features and inspirational PJB tone that musicians have come to expect while its compact size and light weight make it the ultimate in affordable portable bass amps. The BP-200 is a D-Class power amplifier and a pure class A single channel pre-amplifier housed in a machined aluminum/steel enclosure. D-Class amplifiers are highly efficient and therefore produce far less heat than the conventional class AB amplifiers. Other features include a switchable input for active and passive basses, mute switch, 3 Band EQ, headphone out jack, variable input sensitivity control to match instrument output with amplifier, sub sonic filter to reduce excessive loudspeaker cone motion, balanced line out with pre/post EQ and ground lift switches, pre amp output, line out jack with Neutrik high-current socket which can accommodate 1/4 jack or a Speakon plug, 200 Watts RMS at 4 Ohms and 120 Watts RMS at 8 Ohms. The BP-200 will work on any AC voltage from 100- 240 volts AC enabling it to conveniently travel worldwide without having to switch to local AC supply voltages.
