Members joedobronski Posted December 9, 2012 Members Share Posted December 9, 2012 I need to run about 50 feet from a flat screen tv - RCA outs. to a Mixer RCA ins. is the best answer to run two 50 ft XLRs and convert to RCA on each end? or maybe 50 foot balanced 1/4 inch and convert to RCA on each end? or none of the above?Thanks Joe Link to comment Share on other sites More sharing options...
Members PureSoundEnt Posted December 10, 2012 Members Share Posted December 10, 2012 I remember I had to do something simillar like that in the past. What I did was purchase the longest pair of RCA cables that Radio Shack had. They were 33ft long. So I purchased 2 sets and 2 RCA coupler jacks to connect them together. It worked perfectly.

Members zzzxtreme Posted December 10, 2012 Members Share Posted December 10, 2012 try the above suggestion. if you find the "fidelity" lacking, (shouldn't be noticable though), Palmer sell those line level cable extender thingy for very long unbalanced connection Link to comment Share on other sites More sharing options...
Members scarecrowbob Posted December 10, 2012 Members Share Posted December 10, 2012 You can get RCA cables that long:http://www.monoprice.com/products/pr...seq=1&format=2 Link to comment Share on other sites More sharing options...
Members agedhorse Posted December 10, 2012 Members Share Posted December 10, 2012 Yuck, all kinds of potential for noise, especially ground loops. Take RCA out, into passive DI's, then 50' of XLR into a balanced input on the mixer. You will likely need to lift the pin 1 ground if the source's power cable is grounded.

Members Unalaska Posted December 10, 2012 Members Share Posted December 10, 2012 With our karaoke band I use 40ft of RCA-RCA composite video and it works really well. Buy the hosa 20ft cable and rip the two cables apart. Use an f-f adaptor and you're done. I also made 4 or 5 pairs of XLR to RCA using pins 1&2 only, 3 is left open. Then labeled the XLR shell so people know not to use them for audio. Link to comment Share on other sites More sharing options...

Members RoadRanger Posted December 12, 2012 Members Share Posted December 12, 2012 ... or you could do it the right way. Two 50 foot XLR cables and two of these (or equivalent):http://www.zzounds.com/item--ARTDTI Link to comment Share on other sites More sharing options...
Members Siklo Posted December 12, 2012 Members Share Posted December 12, 2012 A good quality audio isolation transformer installed at least on one end would help to remove some of the hum and noise collected by such long cable. The problem is that long cable works like and antenna and receives electric noises from the Aether. Link to comment Share on other sites More sharing options...
Members Unalaska Posted December 12, 2012 Members Share Posted December 12, 2012 I doubt the transformer isolation would word for video frequencies. But then again I don't really know. Link to comment Share on other sites More sharing options...

But then again I don't really know. Isolation of very high frequency common mode noise requires special transformer construction with 2 inter-winding shields.
