LM1036 Circuit Question

Postby kinski » 06 Jul 2018, 05:36

So, I wanted to add some EQ options for my home stereo system, as it currently has no EQ controls. I'm gonna mess with the LM1036 chip. I was lazy and just ordered a mostly prebuilt PCB of the stock data sheet circuit. Its got controls for Volume, Bass, Treble, Loudness, and Balance. All fine, except I already have a balance control in my system and don't want to add another one. So, any ideas as to how to remove the balance control so its just fixed at 50/50. The PCB should arrive in a few weeks.

I've been reading the data sheet a bit. But I'm still not quite sure. Its has to do with the voltage input to pin 9. Perhaps just remove pin 9 from the circuit entirely? Anyone able to take a look? It would be much appreciated!

Replace the balance pot with 2 x 22k (or 24k or 27k) resistors.

Thanks! Just saw this. I'll try this when the board arrives.
