Tone control circuit diagram using TDA1524A:

This is a tone control circuit diagram using TDA1524A. This is an audio equalizer Tone Control TDA1524A. This circuit diagram can control the Base mid and tone. This circuit needs 12 voltages. we can use 12 to 15 voltage. this is a mono-circuit diagram. Every amplifier needs this type of pre-amplifier to produce good sound quality. there are many kinds of pre-amplifiers. Stereo and mono are both types of circuits; this is a mono-circuit diagram. some people use 3 pre-amplifiers. like volume bass and tone. Some people like transistor pre-amplifiers, and some people like Ic-based pre-amplifiers.

here, used four 50k variables to control the volume, bass, hi, and tone. 10k 1.4watts resistors, 220 ohms, 4k7 ohms. 15nf, 56nf, 220nf, 10nf. 10mfd capacitors, 330mfd capacitor.

The circuit diagram is

One message: Hello, I have built a pre-amp based on the TDA1524A Philips IC (the kit is a ‘SmartKit’). It sounds very good as the front end of a Velleman 4040 Valve amp but I’d like a brighter treble response. The spec sheet states 15dB +/- @ 16khz and I’d like to increase this a little. I have wired in a ‘loudness’ circuit which does increase both bass and treble but also greatly increases hiss thus I’d rather ‘tweak’ the TDA1524 circuit if possible. Any ideas, please?

Transistor circuit diagram 2sa1943 2sc5200

This is an audio transistor circuit diagram 2sa1943 2sc5200. it’s a mono amplifier. this amplifier can make 100 watts. PNP and NPN are used here. We can also use other PNP and NPN transistors. here in this amplifier, we can use 20-0-20 voltage to 50-0-50 voltage and 3 amperes. for the stereo amplifier, we need a dual circuit. we know that voltage X amperes= watts. then 20 voltage 3 ampere= 20X3=60 watts. 30X3=90 watts. normally we can use 35-0-35 voltage to get a good performance.
