Professional Conference Amplifier
Overviews
The pro amplifier has a built-in efficient transformer and hiah capacity filter power supply.This helps ensure lower distortion, greater
low frequency control force and clearer voice when the amplifier outputs at full load. The pro amplifier offers three output modes,including
stereo,mono and bridge output.The use of time delay relay circuit allows soft startwhich helps protect the speaker against electric
shock during POWER ON or OFF.The pro amplifier is widely used on many occasions for speech transmission and sound reinforcement.
