How to use balanced inputs on Delta 44

Ok, my delta 44 has 4 balanced inputs, as far as I can tell, and my new keyboard (Roland Fantom x7) has 2 balanced outputs, as can be seen in this photo of the rear panel..

(the x6,7,and8 have the same rear IO)

now My question is, can I use one Stereo(Balanced) cable from one of the 2 balanced outputs on the back of the keyboard into one of the 4 inputs on my Delta44? or do I need to run two stereo/balanced cables from the keyboard into the delta 44? thanks!!!

(Btw there is no difference between stereo and balanced cable right?)
 
you still need two cables. balanced DOES NOT mean stereo. the reason there are two signal wires in a balanced cable is that they are each carrying the same signal, just one is 180 degrees out of phase with the other. when re-combined, this cancels out any noise introduced while the signal was being carried down the wire.
 
okk, I see, so for stereo sound, I still need to have the Dual cable setup going to my computer, but is a balanced cable the same thing as a stereo cable? just that the "balancedness" is the fact that the balanced mono output and balanced inputs use both sides of the stereo cable for an inverted mono signal?
 
I guess what I really need to know is, when I go to guitar center this evening, Do I look for 2 Balanced Cables, or 2 Stereo Cables
 
yes, i think you get it.

the idea of a stereo cable only makes sense for things like headphones. there, you have two independent "hot" signals that share a common ground. a cable only becomes balanced when each "hot" signal has a "cold" signal (i.e. one that is 180 degrees out of phase with the hot).

theres no such thing as a "stereo cable", unless we're talking about a headphone extention or something. you want a balanced audio cable, which are commonly referred to as "TRS" cables (TIP, RING, SLEEVE)
 
One more question, Something like a guitar will not benefit from a balanced cable because it doesnt have a balanced output correct?


would using a balanced cable to join a strictly balanced input (computer interface) to an unbalanced instrument cause phase cancellation? since the guitar would be sending out 2 uninverted signals down the balanced cable, and then the balanced input on the computer interface side would be flipping one of the uninverted signals? or does the guitar only send out a single signal throught he balanced cable, inwhich case it wouldnt matter if it were inverted because it has nothing to cancel out with?

correct.

correct again. the output of an instrument must be balanced; it is the electronics in the instrument, not the cable, that produce the inverted signal.
