The adjustable frequency Bass Crossover circuit is based on two opamps (tl071 tl072) integrated circuits, the operating voltage is symmetrical +15v -15v, there are two pots for gain and frequency settings, the frequency range is 10…60hz. Since the circuit consumes low power, it can be operated with zener regulated or 78L15, 79L15 regulated power supply…
The effect circuit is based on two TL072 op amps, the VR2 100k potentiometer is used to adjust the bass sound, the circuit is powered by a 9-volt battery, since it does not consume much current, it works for a long time with a quality alkaline battery, there are layout plans, schematics, and PCB printed…
ICL8038 20Hz 20kHz audio signal generator circuit can be useful in testing various circuits, especially amplifier circuits. The heart of the circuit is ICL8038 (Precision Waveform Generator/Voltage Controlled Oscillator). Frequency adjustments are made with 100k potencies on the circuit. The working voltage is 12 volt dc. Three small, simple sound generators that produce a rectangular,…
Prepared by: Ahmed Saykal – Subbass filter circuit based on TL072 opamp not only more complex, integrated and a few passive components prepared with 5.1 sound system a lot, but to be effective in certain circuits of this type are used. Sub-bass filter circuit symmetrical +12 volt supply and l7912 l7812-12volt regulator with an integrated…
Circuit 2n5457, j201 fet and tl071 opamp based on the pcb drawing and there is a list of materials. You must use a 9 volt battery to feed the circuit. You cannot get quality sound with different power sources. It already consumes very little power. A quality alkaline 9v battery runs the circuit for a…
Very simple mixer circuit bc457 3 of passive elements (resistors, capacitors) consists of four channels have input dc voltage between 9 … 16 works with a 9 volt battery can be used with NPN transistors can be bc 547/548/549 or 2n2222 etc … any small signal NPN appropriate, simply follow the B / C /…
Prepare a musician playing a guitar preamp tone control circuit “gain, deep, press, bass, treble, medium” and make controls debra opamf TL072 JFET transistors on the board. Supply voltage 12 volts dc. 4 amp 12v battery and circuit performance would be better if you can use the parts list diagram drawing PCBs are Guitar Preamp…
