Hey folks,
I'm trying to add some channel mute switches to my Yamaha PM1000 console. I think the best way would be to make the switch short the channel's 33k summing resistor to ground. However, in the schematics, it appears that there is a separate resistor for each bus, depending on which it's assigned to. This may complicate things because I'd need to switch 4 resistors with one switch.
The next best spot *seems* to be right after the amp stage that feeds the bus output assign switchbank. My question is, if I make the switch cut the output of that amp stage, should I just break the connection, or should I short that connection to ground?
I guess it would also be possible to cut the signal right at the channel input jack, though that's probably not ideal.
If anyone can think of a better way to do this, please let me know.
Schematics are attached, the area in question is right above the circled section.
