Usually the amplifier is shorted output transistors, DC, power failures, this situation gives reliable, though valid in the lecture but integrated requirements may vary according to the situation of failure. It makes more sense to add additional circuitry to protect the loudspeaker DC-protection circuits to detect and relay the DC output of the power amplifier…
In this article made with LM3915 integrated LED vu meter is shown in Figure 10 . VU meter circuit feature , listened to music according to the severity of the LEDs are lit . So vu meter circuit indicates the level of severity of music . Music of the bass, treble and volume regardless of…
The use of voice-changing circuit will sound interesting and fun changing the tests gives the circuit except for the passive elements in shades of Danılt Min ca3240 (bimos op amp) and the tl072 (jfet input opamp) based on clean and effect by setting the potansiyometreleri op evening sound is being changed. The circuit can be…
Marshall jcm800 emulation circuit of preamf, treble, mid, bass, master, and volume control can be made. Circuit 9 volt battery is working with control floor J201 JFETs, MOSFETs used are already a lot of guitar effects volume control circuit of this transistor with frequent, often I am having characteristics most good is not commercially available…
Active filter circuits used in audio circuitry, especially the bass, treble, etc.. general op amp for audio integrated circuits are built on a variety of circuits quite simple overall structure is composed of resistors and capacitors on the main controller integrated op amp. Scheme not specified in the application note this integrated power leg tl082,…
Class A amp circuits are accustomed for some reason class a tone access control systems never occurred to me that been the performance I am very curious probably a normal tone control circuit based on is much better circuit critical materials 2SA872, 2SD666 transistors on the market Does not know, but there will not like,…
KA2281 previously with various vu meter circuit I made , but all mono circuit stereo manufacturer has two channels has been a challenge but in the end a bit of trouble in the scheme worked beautifully 🙂 Original diagram 15, 16 pins between the 50k resistor connected in this way the circuit full does not…
c 4 1SH29B lamp used bass, treble, gain and volume controls able supply 200V 15mA and 5v 200mA DC separate circuit diagram in key areas of current and voltage data indicated pcb print circuit drawing layout quite been good over-current for the author 10w transformer He trained with the circuit. 1SH29B sprint circuit’s layout has…
VU meter circuit 2 Dot / Bar Display driver lm3916 used the audio Gisira upgrades in 1 for TL072 op amp has my voice according to the severity of 17 LEDs flashing audio inputs in addition to the 100k potentiometer connecting the LEDs burning level, you can set. 12v dc circuit is working with VU…
Active filter circuits NE5532 opamp made using the 2 and 3-way versions available (low pass, band pass, high pass) also opamp in the calculation formulas and examples in the scheme’s entire circuit of the PCB drawings are operating voltage of + – 15v symmetric all circuit files: FILE DOWNLOAD LINK LIST (in TXT format): LINKS-14555.zip
