A detailed subwoofer project. Test audio files designed for a 12-inch 400w speaker are shared (in .wav format). Parametric equalizer active filter is a quality design. Boost-Cut, Frequency, Q, X over, Phase, Volume settings can be adjusted. When you listen to the test sounds, you will clearly understand what the equalizer and filter circuit can…
TDA1554Q and LM1036 with the bass, treble, volume and balance controls can make high quality cheap complete amp circuit TDA1554Q supply and output options, thanks a lot, car radios, household, pc sound system is used in two integrated with 4x22w a cheap car amp can be Key features 4x11w or two depending on how power…
For a long time doing a project I just kept thinking (actually one or two attempts but I just tried it out a complete project were not) to my rescue my friend has grown up can I say, I am an amp asked us a good circuit we tried to do First, our choice of…
A lot 5.1 sound system used in the quality of an amplifier IC lm1875 circuit two used this integrated shape and leg connections TDA2030A is the same amp for the supply rectifier and filter capacitor the same pcb on the tone control (bass, treble) for what 5532 op-amp used in addition to called bypass feature…
LM3886TF Amplifier circuit pretty a quality PCB design has to supply the diode bridge and filter on the capacity also for the volume control stereo 100k potentiometer attached LM3886 inputs and outputs used in this opamp NE5532 instead ad827 used opamp beslemesiç the same pcb on the 7815 and 7915 fixed regulator IC supply with…
A circuit I tried a long time ago was the only channel I made. The bridge 2030 outputs were powered by transistors. In this application, plus two circuits connected in parallel with the bridge, the power was doubled. Amplifier supply voltage is symmetric +- 22 volts, unless an error is made, a circuit that is…
STK400-290 can deliver 3X 50W power, a quality 2+1 amplifier circuit is made by adding a bass filter circuit created with tone control transistor and NE5532 4558 ops. Also, input selective bass amplifier and tone control have Loudness feature. Material values are not selected in the circuit diagram, but the values in the pcb top…
Amplifier Circiut Npn and pnp transistors built on 4.5 volts, an amplifier circuit is working with 3 alkaline batteries can be used with LED warning when the battery level drops gives 99s also prepared with protel pcb file available Simple OTL Amplifier Schematic Simple OTL Amplifier Circiut PROTEL2.8 pcb
My brother @ TamircihasSTK080 have made an amplifier with a nice supply of Anfi is symmetric 2 × 24 volt 60 watt transformer can use Friends of amplifier circuit printed circuit boards has been prepared by me. Circuit gain and excessive background noise is reduced to 22 to prevent deportation circuit is now working smoothly.…
Far as I know with the lm3875 and LM3886 class A-AB study classes have previously LM3886 did the difference between the two is one of the circuit between the simplicity and the other LM3886 in the bass than the one in the foreground and a strong, LM3875 the bass and other details evenly dispersed. Circuit…
