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 can control preamp, treble, mid, bass, master, and volume. The circuit works with a 9 volt battery, j201 jfet mosfets are used in the control stage, I often come across this transistor in many guitar effect sound control circuits, its characteristics are very good, if it cannot be found in the…
Active filter circuits are used especially in audio circuits. There are various circuits generally based on op amp integrated circuits for bass, treble etc. sounds. The general structure of the circuits consists of very simple resistors and capacitors. The main controller is the op amp integrated circuit. The supply legs of the integrated circuit are…
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 are made using ne5532 opamps, there are 2 and 3 way versions (low pass, band pass, high pass) also there are formulas for opamp calculations and sample schematics, there are pcb drawings of all circuits, working voltages are +- 15v symmetrical.
