sdeverall Posted September 4, 2016 Share Posted September 4, 2016 So I finally got sick of my battery always being dead on my JTV59 and purchased the Variax Power Cable Kit, which is AWESOME!...with one semi-major flaw for me...I can't seem to find a good long-length TRS cable to use with it! I didn't realize initially that it needed a TRS until I received the included 15' cable. I have become a HUGE fan of braided cables and can't seem to find a good braided cable to use with the power kit. Anyone else have this problem and have you found a great braided cable to use? I'll post if I track something down for future forum members. -sd Quote Link to comment Share on other sites More sharing options...

sdeverall Posted September 6, 2016 Author Share Posted September 6, 2016 Not sure if this will work, but I ended up "building" a braided 20' TRS using XLR adapters: https://www.amazon.com/gp/product/B00NQPHIR4/ref=oh_aui_detailpage_o01_s01?ie=UTF8&psc=1 https://www.amazon.com/gp/product/B000068O4I/ref=oh_aui_detailpage_o01_s01?ie=UTF8&psc=1 https://www.amazon.com/gp/product/B0002GZLX8/ref=oh_aui_detailpage_o01_s01?ie=UTF8&psc=1 Hopefully its not too bulky with the adapters, but I'll post if it works (or not). -sd Quote Link to comment Share on other sites More sharing options...
psarkissian Posted September 6, 2016 Share Posted September 6, 2016 15ft TRS to the XPS is normal, keep it there. If you're going to go for a longer length, make from the XPS to the amp, and try to that length down to about 25ft. Don't go beyond 30ft.

sdeverall Posted September 6, 2016 Author Share Posted September 6, 2016 Thanks for the advice! I assume the fact that the TRS carries an additional power current that there are interference issues running longer lengths? Quote Link to comment Share on other sites More sharing options...
snhirsch Posted September 6, 2016 Share Posted September 6, 2016 Probably more the risk of signal degradation and voltage drop than anything to do with interference between power and signal. Quote Link to comment Share on other sites More sharing options...
psarkissian Posted September 6, 2016 Share Posted September 6, 2016 TRS:: Tip/Ring/Sleeve in an active circuit like this is typically use for signal, +Vdc and return (or some analog circuit common or ground). Over long lengths, there can be a sag in the DC rail and/or a resulting change in the impedance. Change in impedance can contribute to hum noise. DC regulation can do only so much. So yeah,... snhirsch has got it. Quote Link to comment Share on other sites More sharing options...

Loads of noise interference possibilities. Quote Link to comment Share on other sites More sharing options...
snhirsch Posted September 9, 2016 Share Posted September 9, 2016 XLR cables are generally not shielded like guitar cables. Loads of noise interference possibilities. An unshielded microphone cable would be as useful as a screen door on a submarine. Of course they are shielded, sometimes doubly so. Quote Link to comment Share on other sites More sharing options...
cruisinon2 Posted September 9, 2016 Share Posted September 9, 2016 An unshielded microphone cable would be as useful as a screen door on a submarine. The contractor that sells them to the Navy calls them "passive humidifiers"...they can charge more that way. ;) Quote Link to comment Share on other sites More sharing options...
psarkissian Posted September 9, 2016 Share Posted September 9, 2016 XLR is a balanced line, and the 3rd line ties to the shielf for chassis ground. 50-Ohm XLR is for mics, 110-Ohm XLR is for L6 Link. TRS guitar is for guitars with active electronics like a Variax or JTV. Because of impedance considerations and its affect on cable performance, many of the afore mention cables have length limits. So don't go beyond that. Quote Link to comment Share on other sites More sharing options...

psarkissian Posted September 9, 2016 Share Posted September 9, 2016 "Is the JTV 1/4" output a TRS of some kind?"--- Yes. More about that in the Knowledge base. TRS:: tip= signal, ring= +V, sleeve= return. It's like that with many guitars with active circuitry. Quote Link to comment Share on other sites More sharing options...
