Hi Javi,

It takes a little experimentation, if any are used. Most folks build the circuit as recommended. Try using trim pots where you think you might need or want adjustment. Then remove the trim pots, measure their values, and replace with 1% resisters. Some folks have also placed different input resisters on the input selectors to change the values based upon source system impedance loads. In other words the input resisters are infront of the selector for each source, rather than a single set of resisters behind the selector.

Part of the fun of DIY, we can do stuff like this that commercial products cannot.

Good luck,

Default Resistor value?


Are you asking the value of R15?

Hi Thomas!!
I ask for the resistances located in the PCB IN/OUT signals relays, 4 resistances of 1/4W 1% appear I have a picture of this mounted badge but I don't distinguish their value well, but as they have commented me, each person puts the value that considers opportune for that reason I will experience with potentiometers of 500 Ohm there am I will go adjusting until getting a good value but I have the impression that adding resistances of between 100 Ohm and 120Ohm, serious good but any suggestion that you make serious very interesting for my, thank you and forgive for my disastrous English.

Best Regards, Javi.
