Audio 4 is marginally simpler as you can get two mono RCA cables and be done. Still not worth the upgrade imo.
While the Audio 2 ships with phone plug to stereo RCA cables, these are probably unusable/too short (I’m saying probably since I don’t own an Audio 2). I would get a real short 1/4" phone plug (male) to stereo RCA (female) adapter and then two mono RCA cables (male-to-male). If you need the lowest price, I suggest ordering these cables from monoprice.com.
Most KRK speakers have separate RCA (unbalanced) and TRS (balanced) inputs. The Audio 2 outputs an unbalanced line-level signal. Hence one should use the unbalanced input of the KRKs to hook up the Audio 2. That’s why I like my suggestion better than yours. DJTT’s featured a related article some time ago.
Soooooooooooo just to clarify The outs are TRS unbalanced.
Question though.
I originally got the splitter to let me broadcast on ustream (1 would go to my speaker (makie TH 15) and the other would go to my audio-in on my mac) however, i still needed to set my output on traktor to mono so it wouldnt sound like hell breaking loose…even though it was split…
your thoughts?
also. Is there a way to manually set my audio 2 to mono/stereo if i want to use it with ableton (thereby letting me use the monitors for ableton)?
The Audio2 outputs are not TRS in the typical meaning of that term. TRS is used to refer to a balanced connection on a 1/4" jack using the Tip, Ring, and Sleeve.
And the appropriate length RCA cable: http://goo.gl/dot17
Get one labeled “premium”. These are made with shielded coax. They are bonded together but you can easily pull the two cables apart to run one to each speaker.
