[GUIDE] Balanced AKG K702 with detachable 4-pin mini-XLR cable - Page 4

post #46 of 48

I read, some time ago, that people who converted their K701 into dual-entry bought a Right cup to replace the Left one. Then they drilled a hole in the center of each cup.

 

You can't really buy a Left cup to replace the Right one because the stock cable entry isn't centered. This would place the Right cable entry at the back while the Left one is at the front. Ugly.

 

But anyways. As I said earlier, converting an AKG phone to dual-entry is overkill. You still get all the advantages of balanced operations even with a single entry. It's a nice project, though.

Ah that's true, it would indeed point to the back once you put the left cup on the right. Definitely agreed that dual-entry is overkill.

The term "balanced audio" really refers to two effects that both benefit sound quality. Most of us think of differential signaling--running an  in-phase and out-of-phase signal for each stereo channel--when we think of balanced operation. But you can get common mode noise rejection without differential signaling as long as the two + and - wires are of equal length, gauge and their impedance matches. Note "equal length" refers to the individual wires in a channel pair so the extra length of the right channel wires will not cause an "imbalance."

 

I'm hoping to do this balance mod to my AKG K240 Studios.
