Building a Three Channel EQ on a Breadboard
Hey!How have you chosen the resistor and capacitor values?Is there any equations or formula behind that?
Can you replace the lf351 with lm386? I tried that but i can hear only noise. I changed pins 6 and 7 (Vcc and out) for 6 and 5. But it did not work.
Very nice, I favorited it. I'm going to build it when I finish the projects I'm working on.
Is there any need to add power amplifier in the circuit?And if there is then how can i add it?
Look like normal disc capacitors to me. Any that look similar to these would be fine http://www.rapidonline.com/electronic-components/suntan-ts15001h102ksbpa0r-1nf-10-50v-y5p-2-5mm-ceramic-disc-capacitor-08-0200.
you could try something like this http://www.rapidonline.com/Cables-Connectors/TruConnect-PCB-Jack-Socket-Stereo-3-5mm-20-0137?sourceRefKey=YyKBeYhU0&filterSearchScope=1 or you could just find an old pair of headphones and cut the wire off that. You should find 3 wires inside, one red, one green and one black. Red and green are right and left (not sure which way round) and black is common.
no, supply voltage range is 6 to 32v
Can you please specify what kind of capacitors has been used?
HiHow can i ad a 3.5 mm input and output, or how can i connect phone and speakers.Thanks
