The difference between PA power amplifier and PA mixer amplifier
Power amplifier is to enlarge the volume of the PA system,it just the part of amplifier,it need to work with other
mixer equipment. The feature is that it can be connected with more speakers.The power is always powerful than
mixer amplifier.
Mixer amplifier is with the amplifier and mixer ,it is a perfect match amplifier.
General power amplifier is with 20 dB of the first stage amplifier or tone, volume, etc., there are a number of groups
of input; the power amplifier is only responsible for power amplification, up to only a volume adjustment, the general
input is 1-2 group.
It also can work without the before class, you can also put on a volume potentiometer to control the volume in
power amplifier , but before the class is not only used to control the volume, but with condition, the effect will
difference also, power level of the input impedance is hard to say fully match with audio, amplifier input impedance
tend to be too small. Some sources to promote power amplifier, at this time will be used the front stage to perform
the impedance matching
In addition, you can add the front stage of the tone circuit, made up of the mixer, add the amplifier circuit,
do the first stage amplifier, etc..
