I have stacked buffers on the left and right channels so I have put 100 ohm resistors in r11 right and left. My ground buffer is not stacked. I was wondering what resistor value should be put in r11g? Should I put a 100 ohm resistor or a 220 ohm resistor? Any help is appreciated.
The ground channel is the return path for both the left and right channels. If you want maximum capacity from the left and right channels then I would think you would need four buffers on the ground channel.
