oh and to clarify: if you'd use balanced cables they'd need to be balanced on both ends. RCA is not, so there's no point in using balanced on mpc.

so RCA -> 1/4 (TR) cable is what you'd need.

thanks for the clarification! i've been using a monster rca -> 1/4 tr so at least that was the correct purchase.


i've tracked my beat tape out from my stereo outs -> apogee duet 2 using (2) 1/4" tr cables. my boy told me that a 1/4" TRS -> XLR would create a more accurate signal. are xlr's really a better signal transmitter than 1/4"? i know that using an unbalanced cable from a balanced output source definately doesn't help my sound :/

That difference is so little you won't care.

even if the unbalanced cable is 9 feet in length and is near a lot of other power supplies/cables? thanks

You didn't mention all that, lol.

You have some work to do then.

Don't run audio cables parallel to power cables, if they MUST cross then do it like +.

Also this may help greatly reduce noise along your analog audio cables.

i should have been clearer lamp, my fault haha.


could you just briefly elaborate on why audio cables shouldn't run parallel to power cables? and this + formation? confused.



do you still lose audio quality if you use a 9th foot (or any lengthy) balanced cable like you do when you used the unbalanced? or is longer length cables losing quality only an unbalanced cable issue? i just thought i should buy longer cables to have that extra length.

Don't run audio and power cables cables together side by side like this =

IF they need to cross each other then make them cross each other like this+

The shorter your analog cables the better and less chance they have of getting outside interference is the reason I saw as short as possible. Maybe re-arrange your gear so that the distance is shorter. Unshielded/unbalanced cables run a great risk of interference from emi (electromagnetic interference and ground humming) than balanced/shielded cables do.

Also look into ferrite cores placed along the audio cable.

Alot of reading but it might help explain better than I can
