LM1875 20 Watt Audio Power Amplifier
To assemble the amplifier 20 watts with IC LM1875 component is not needed much support. 20 watts power amplifier using LM1875 IC in this article using symmetrical power supply. The virvuit of 20 watts audio power amplifier with IC LM1875 can be used as an experiment or first project for the reader, because it is simple and assembly of high success.

LM1875 amplifier circuit with the above may result in the strengthening of the voltage up to 27dB for each channel (1 channel 1 IC). Strengthening the voltage can be changed by changing the feedback that is R5 R (on the circuit above using R 22K). But the tension reinforcement can not be less than 20 dB because it can cause oscillation. For the power supply or power supply 20 watts power amplifier rngakaian with lm1875 can use travo 2-3A with CT.

6 Watt stereo power amplifier schematic
Basiccally,this amplifier works with the IC, which is where ic is associated with several other components in the supply and use DC voltage, which corresponds to the needs of IC above course on the circuit schematic. For IC , stands intregated circuit used is ic LM379 which has a maximum 6 Watt stereo output. This IC manufactered by NS and with SDIP-14 package. While other components needed in the circuit schematic , you can see components of the list below.

120 Watt Microphone Amplifier
Pyle Pro PT210 120-Watt Microphone PA Mono Amplifier with 70-Volt Output This 120-watt microphone amplifier takes your voice to the after that level! The amplifier's extensive frequency response makes it right and proper in place of amplifying melody before vocal list material. It can be alive used for live bands, workforce paging systems, shared announcements, before a variety of other installations. It’s got two front ¼” inputs for mics, apiece with its own separate volume control and talkover.
Plus, here’s two stereo RCA inputs on the back - together with single so as to takes low level phono input from a turntable. The 3-group EQ (100 Hz, 1 kHz, 8 kHz) lets you squeeze the sound to your exact supplies. This amp is compatible with 70 against aide systems too. An unswitched outlet on the back instrument you’ll by no means stay looking in place of an outlet. Runs on 110 and 220 in opposition to.
