Difference Between Mixer Digital Amplifier and Digital Public Address Amplifier
Amplifier, it's name is the power amplifier. As the name suggests, amplifier is to amplify the power. The power amplifier belongs to the post stage amplifier, and its function is to enlarge the signal sent by the front stage processing equipment to large enough (the final frequency of the signal is in accordance with the frequency of the power amplifier, for example, 100W's amplifier can reach 28V with 8 European load) to drive the sound box. Amplifier is the "power amplifier" for short, the output signal amplitude and the intensity of the signal source (such as the CD/DVD/ card holder radio head, mp3 and so on) is not enough to drive high power loudspeaker (sound box horn), so it must be amplified by the amplifier. The mixer, as the name suggests, is used for tuning. The mixer belongs to the front stage processing equipment, and it usually does not have a built-in amplifier.
