DJM 800 & Korg Kaoss Pad Quad?

The 800's send/return are 1/4 jacks.  I could be wrong but I say you need that to go to the send and return.  You would need rca to 1/4 jack cables.

Here is an example pic     http://www.google.ca/imgres?imgurl=http://www.long-mcquade.com/files/1651/lg_A__PR.jpg&imgrefurl=http://www.long-mcquade.com/products/1651/Pro_Audio_Recording/Cables/Apex_Electronics/A206PR_-_Dual_RCA_to_1_4_Cable.htm&h=444&w=598&sz=44&tbnid=YRexqwcUY5O1OM:&tbnh=90&tbnw=121&prev=/search%3Fq%3Drca%2Bto%2B1/4%26tbm%3Disch%26tbo%3Du&zoom=1&q=rca+to+1/4&usg=__XcUsq2PyYAPrtVGS-WN_F6kRStg=&docid=83wvSq_DHDNuxM&hl=en&sa=X&ei=KsUtULnkDujV0QGHwoGQCA&sqi=2&ved=0CFwQ9QEwBA&dur=4104

Yes exactly, but is it doable? No loss of audio or such? Just straight as 1/41/4 ?

It should work just fine as that's the only way to do it.  I rented the KP3 once to test out and hooked it all up and didn't notice any issues...

Thank you very much John. :)
