Just to be safe. I used 100 ohm resistors in series and 47Kohm to the analog ground for each channel. You could skip at list series resistors and solder BG legs to the phone jacks legs directly. Plastic tray that supports the board has holes in it. If you use wires you can solder them through the holes. To make it easier you can just file the whole thing down as I did.
Just to be sure, does the text in bold mean that the it's possible to skip the 100 ohm resistors and just use the capacitors, or is both necessarily required?
