This tone control circuit is designed using few common components and the LM4562 ultra-low distortion, low noise, high slew rate operational amplifier optimized and fully specified for high performance, high fidelity applications.
Using LM4940 dual audio amplifier circuit can be designed a very simple low cost audio solution for demanding applications in flat panel monitors and TV’s, but it can be used for some other audio applications .
The LM4940 dual audio amplifier circuit does not require bootstrap capacitors or snubber circuits.
This 4 channel audio mixer circuit project is based on the lm381 low noise dual preamplifier IC .
For powering this audio mixer circuit electronic project you can use a DC power supply circuit (or a battery ) that will provide an output voltage between 9 and 24 volts .
