Roland Crown 4*800W power amplifier
The four-channel power amplifier adopts 1U 9-inch standard design, which is small in size, light in weight and easy to install. The circuit adopts Class D power amplifier module and reliable and efficient R-SMPS power supply system, and integrates active power factor correction circuit (PFC). PFC makes this power amplifier more efficient and controllable, and has a very high power density. The current waveform can be adjusted according to the AC voltage waveform to adapt to a wide range of voltages around the world, so that a single standard current circuit breaker can withstand higher power operation.
