Wires needed for actives to computer?

post #1 of 4
Thread Starter 
Hey guys, i'm having a bit of a trouble figuring out which wires I need so I can connect 2x Rokit KRK rp6 g3 to my computer soundcard.. yeah really!
There was no cable included with the speakers other than the powers, and with that many cables of any kind i'm asking the help of pros

I think I need XRL cable to connect a speaker to another? then RCA male + female to the card?

Card is Xonar DX

Thanks! handlebarssmiley.png

The DX connection is unbalanced, so a 3.5mm-to-2xRCA cable.
Like this one here

The speakers act as a single unit, they do not act as a pair. Meaning that the speakers don't have a cable connecting eachother, they both go directly to the soundcard.
And as a headsup: you may get problems with groundloop. (Click to show)
Groundloop is made when both the speakers and the PC share the same ground and you are using unbalanced connection between the PC and speakers.
Groundloop = loud static noise and moving the mouse alters it.

You can cut the groundloop with groundloop isolator, balanced connection (need a mixer/etc. for this) or by isolating the ground from your speakers (electrical tape to the grounding pins).
The most practical solution would be putting the speakers to a separate ground, but most houses only have one ground that is shared by all the power outlets...

Big thank you! that groundloop thing makes all the sense in the world with my current rig D:

Is there a difference in getting a 10ft 3.5mm to 2x RCA vs say 6ft to 2x + extra 2x to extend single male to female? I mean would I lose some sound vs a straight up long 2x rca, asking since 10ft+ 3.5m to 2x rca aren't too comon and I need range :/

I mean extend it with 2x of these: http://www.monoprice.com/Product?c_id=102&cp_id=10218&cs_id=1021810&p_id=656&seq=1&format=2

Also, when talking RCA, is there a difference between monoprice vs a certain brand?

edit: Would I need a groundloop isolator on each end of the twin rca? aka 2x isolators? or 1v isolator for 2.5mm jack then plug the 3.5mm / 2x rca to it

There is continuous debate about the effects of cables on sound quality.

Suffice to say, you can buy those cables for $3 and you can buy then for $3,000.

I'm in the camp that believes cables are important.. There's a lot of cables that make a difference in the sound, few that make it better (or, technically, what goes out matches more closely what comes in). That's not to day "different "is bad, just different. Sometimes different is what's needed (ie less base, smoother high frequencies, etc.).
