There's a ground that's lifting or floating somewhere, the clock signal is demodulating into the audio band. It will need servicing by an authorized service center, since they would know the product.

"I thought this output is an either or thing. Either L6 Link or AES/EBU"--- It uses AES/EBU 110-Ohm cable for the Line 6 Link, which is to AES/EBU standard circuit type,... and not XLR 50-Ohm mic cable.

Tried that. Too many so called techs weren't as tech as they claimed. And so I had to do their set-ups all over again from scratch. So that didn't work. But we're getting off-topic here.

No secrecy, no cheap components,.... It simply wasn't designed to be that way, with both outputs running simultaneously. It's as simple as that.

"...I saw a comparison of the JTV to the Standard in (I think) Thomann.de (I live in Germany) and it said the JTV had piezos and the Standard did not"--- It's the same piezo for both of them, just a different saddle mounting.

It's not the price of the components, it's that they are low volt components. Your laptop wouldn't handle an over voltage or high current pull-down, anymore than a JTV would. Nothing would please me more than to do videos on how stuff works and why. It would put to rest many misconceptions about many things.

How long has it been since the tubes (valves) were replaced?

Agreed about the Dr Dre's,... sorry Doc. Inexpensive Sennheisers or the better (a little pricier) AKG K240's are good. Something with a nominal impedance of 680-Ohms to 1K-Ohm.

What brand and model of headphones are you using?

TRS 1/4" and VDI,.... it's a pair of unequal branches. They won't pull down (load) the same. So using them both simultaneously creates problems. I can't get any deeper than that about it with end users. And I do have background in audio circuit design and apps (decades of it). And I've serviced hundreds of these. I know what they can and can't do. I'm just trying to keep all your gear from ending up on my bench.

Check to make sure that both of your XLR's are 50-Ohm cables for XLR audio outputs. Don't get them mix in with Line 6 Link cable,... it's a different impedance.

Yes Clay,... I'm here to keep everyone's gear from ending up on my bench. Thanks. As for the components,... they actually pretty good, and I design circuits with these. It's more about it not being designed for use with both out's simultaneously. If there were more space in side, or a properly impedance matched signal boost attachment that could do the job without circuit pull-down, then I'd be saying "go for it". But that's not the case here. Bummer.

I think that's out to 20kHz? Typo? silverhead,... essential right, Flat response,... make no EQ,... that would make sense. Flat across the response range would,... and no EQ, it would also have to be in-phase and maintain that across the entire range. What Tannoy used to call 'phase coherent'. Not something I deal with much. It's become a big thing with FOH board ops guys in recent years.

IR, Impulse Response,... Put an impulse signal into a black box circuit, and the response is what you get at the output. It can be observed in time domain, as with an oscilloscope, or frequency domain, as with the FFT (Fast Fourier Transform) display of a spectrum analyzer.

specracer986,... yeah, more than likely. I've had these discussions with my then, opposite number over there. Might be one of the reasons for the change. Or simply didn't feel a need for two cables for the Helix demo.

Not only does stevekc's guitar look good, it also plays nice,... ... I've had the pleasure. Did a good job on that one. Nice!

No secret sauce, just basic electronics. Paul is in the UK, the vid was made in up'd to You Tube in 2011. And we haven't had a Line 6 UK, since 2014. So this vid is probably out of date. Sorry "cruis", no secret sauce stuff here today, just boring facts about audio circuits. Love these exchanges with you, always a sharp one. Keep up the good work. :)

Same piezos, different mounting saddles.

Amp chips in the XT Live headphone output used to blow when someone used headphones with the wrong impedance range. That problem was solved. Not so easy to do the same here, it's not entirely the same circuit as the XT Live, but the same kinds of load impedance principles apply here. I'm the guy that services and repairs guitar here at Line 6, and so I know the circuitry intimately, and been using and designing circuits with these chips for decades. So I know what the limits of the amp chips are. I don't have time or space to do an electronics semiconductor theory class here. If you're going to do something like this, be very careful of how you load it down.

Not BS,... but it is a strain on the amp circuit in the guitar.

Using both simultaneously will put a strain on the amp circuit in the guitar.

For the DT50-112,... Yes, should be 8-Ohm.
