Balance and fade

01:33:52

Is the simulator broken? By all accounts a pot wired this way should split the signal and maintain the ratio.

If you were measuring current instead of voltage, what you say is true, the voltage calculations work out fine.

@rickybscs, look at your circuit again. You have identical voltage at either side of the potentiometer. No potential difference across the potentiometer means no current flow. No current flow means no voltage drop across the potentiometer.

The way it's wired up results in 2 paths of 11k resistance in parallel, heading to ground

Something strange happening here.If you turn the pot to the blue side ,the green amplitude should rise .But it doesn't?Same problem if you turn it the other way.You may be right.Is the simulator broken?

Looks ok to me, do the maths.

Thanks all. I may have updated this since. If I attach the wiper to ground I get the intended effect. Im working on a preamp 2 to 4 channel with balance and fade. Im trying to use the pots for balance and fade. Now how to get it to attenuate to 0db when the pot is at the extremes...
