Plenty of power supply. 32 pieces of 10000microF for  each channel.
 
 
State of the art technology multi- stage power supply circuitry are used for PA 3U amps. This method reduces heat and greatly improves efficiency of the amplifier, which leads to an excellent stability and durability.
 
Multi- protections: PA 3U equipped protection of full short circuit, thermal, RF, On/off muting, DC- fault power supply shutdown and soft start.
 
A built- in intelligent Clip function. It has a broad range of signal input (0dB 8.5V). Even the CLIP LED lights up a long time in an unexpected situation.
 
Muti-speed cooling fans installed. It works faster along with the rising of amplifier temperature. This avoids some mechanical noise in quiet environment.
 
PA 3U can work stably at 2ohm condition for long period. It is a breakthrough in traditional high power amps in the industry.
