Braided TRS Cable to use with Variax Cable Power Kit?

Recommended Posts

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.

Not sure if this will work, but I ended up "building" a braided 20' TRS using XLR adapters:

Hopefully its not too bulky with the adapters, but I'll post if it works (or not).

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.

Thanks for the advice!  

 

I assume the fact that the TRS carries an additional power current that there are interference issues running longer lengths?

Probably more the risk of signal degradation and voltage drop than anything to do with interference between power and signal.

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.

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.

The contractor that sells them to the Navy calls them "passive humidifiers"...they can charge more that way. ;)

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.

Is the JTV 1/4" output a TRS of some kind? I didn't know that. I'd use a VDI anyway, but that doesn't work with everything.

"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.
