material:

Power-Amplifier650W
The audio amplifier actually amplifies a smaller audio signal, increases its power, and then outputs it. Preamplification is mainly to complete the amplification of small signals. A codirectional amplification circuit is used to amplify the voltage of input audio small signals to obtain the input required by the later stage. The next video will focus on power amplification of audio so that it can drive resistors to get the desired audio.

Descriptions

      The range of power amplifiers is designed for general commercial and industrial public address applications.Rack mount design in 3U type,rated power ranges from 240W,480W,650W,which provides a wide selection to meet different size sound system demanols.Both balanced and unbalanced line inputs make it selectable for installer,balanced line output feeds to another power amplifier as well as secures the signal transmission is lessnoise and longer distance.70V,100V and 4-16 ohm speaker outputs are convenient for installation when selection different speaker matching. Amatching. A master volume control is included.Complete protection includes clip,short circuit,high temp and overload.Indications for power,signal clip,protection and temp.
