Can you point me to some detailed info on 'shunt' mod. I have alps 'blue velvet' 100k pot.
sorry, i don't have a pic.
on a pot:
Input = input signal from RCA
W = wiper
G = ground
connect W and G together for each channel. place a 100K resistor in series from the RCA to Input on the pot to each channel. from the Input after the 100K resistor, connect to the signal inputs on each channel. the ground from each of the RCAs to should connect at their respective channels on the pot at W and G. connect the W and G of each channel on the pot to their respective input ground on the boards.
instead of the signal being across the wiper and conductive material, the signal is "only" across the in-series input resistor. in this configuration, the potential divider is adjusted on the ground leg and not the input leg.
