I am building a passive studio monitor control unit and have built a stereo stepped ladder potentiometer attenuator for volume control of its balanced in and out. Essentially, it is a series 4.7k resistor into a 10k zillion-resistor network (well, 90 anyway) pot as directed by the net. What the heck do I do with the cold half of the balanced in and out? I searched and searched but can't seem to find the answer. It works great unattached but there's gotta be a way to keep the whole thing balanced, right? The pot has 2 ins, 2 outs and grounds.
Don't you want to transform the one 4700 into two 2350 resistors?
If that is not it, draw a picture.

Would I need to do that? It's just a 4.7k on each channel input into the stereo-wired 10k pot. I basically just copied the 10k version of this:
Kikitronic -- DIY Audio Kits: Dale 23 Steps Attenuator
and added the 4.7k resistor to the input of each channel as suggested somewhere else I Googled which works fine with and without the extra series resistor, it just works at a better and lower practical volume level with them in. But, again I have the extra cold wires of the balanced ins and outs and that is what I'm wanting to know what to do with those wires as the hots are the ins and outs, and the grounds of course are the grounds.
