Thanks for the reply! I have really no idea, here is the whole thing actually
Its an amplifier board used in a arranger keyboard. It is a "fixed" type equalizer, so no potentiometers.
I think they might actually tweak 3 frequencies, the service manual of the keyboard states this in the...
Ok, about the frequencies i just noticed that the capacitors used in the example application (pdf) are the same as the diagram shown. Show they would probably be the same:
So what remains is the gain (db), how much they boost or cut those frequencies. For example those, if i'm reading this...
Hi! I have this diagram:
BA3823LS monolithic, five-point stereo graphic equalizer IC is used. Is there any way to calculate the frequencies (hz) that are defined and how much boost/cut gain (db) is applied in each frequency? If i'm reading this correctly the capacitors (C56, C55, ...) are...
