POWER ENGINE 300

These instrument power amplifiers take the transparent Power Engine capabilities to large-venue capacity. Available as either the 300-watt @ 4Ω mono Power Engine 300 or the stereo Power Engine 400 producing 200 watts per side @ 8Ω, these heavy-duty modules will fit in a 2U rack space. The oversized power supply with a toroidal transformer delivers pneumatic punch with a natural transient response, while the tone is pure and uncolored. Each model is super-reliable with top-quality Toshiba power transistors and a heat-sensor equipped cooling fan.
