Machan.. Preamp eken orignal signal eke karanne gain eka poddak wadi karala dena eka.. e kiyanne without preamp api kelina audio signal ekak power amp eka ekata dunnoth, audio signal eka hariyata amplifer wenne na.. may be signal distortion wenna puluwan.

Ex. Mic ekata wenama volume control ekak enwa main volume control ekata additional. Eka awilla kind of pre amplifier. Pre-amp eka anthuwa mic ekaking ena signal ekak kohethma ba Power amp ekata amplifer karanna.

Class gana kiyanwa nam Signal power karana effeciency eka gana kiwwoth

Class A - 25% anith tika waste wenwa.
Class AB -50% (godak use une meka issara)
Class C - 75% (wadi effeciency ekak tibbath Audio signal amplification walata ganne na.. Meka Use karanne RF signal amplification wlata.
Class D - Almost 100% (aluth ena Hi-Fi wala enne this kind of power amp. This is classs working with digital power amp.)
