I would like to try a dual amp setup, using my 500hd and dt25 for one amp tone, and a second amp in mono out one of the xlr outs to a pa as second tone. But I can't seem to separate the tones. Any suggestions?

Pan one amp hard right, and the other hard left.  Make sure you are only feeding one side to the DT25.  Check in the Line6 Link Output section to do this.  Sending the other panned channel to the PA should be simple.

 

Note that there is a problem with this.  Both sides will end up with the same output mode.  While you want to have it set to combo for the DT25 (L6 Link will do this automatically), you want it set for direct for the PA.  This is currently not possible with the HD500.  It's global setting, so it's all or nothing.

Similar problem here maybe you could answer and help me.

 

I am using dual amp setup for years, usually involving AC30 and an other fender-type amp.

So now that I have DT25 and HD500, my idea is to use that combo via L6-link and in the same time 1/4" right audio out of HD500 to my secondary fender-type amp.

 

No problem so far, I configured DT25-HD500 the right way. AES/EBU cable - hd500 puts itself in a "combo power amp" mode and there is the problem.

It sends that signal out of the 1/4" audio out to my other amp. While DT sounds better, second amp sounds worse.

 

I can manually switch "combo power amp" to "studio/direct" and it stays that way until another power-up but I am not sure is this a viable solution?

I have tried this for a few minutes yesterday and will do more tests today so I am not fully sure yet what this does to DT25 sound and the other amp signal-wise.

But it is different for sure.

 

I use HD500 as a FX only device as I have always done which defaults DT25 to channel B (where I have uploaded the amps I like). That is fine for this application.

HD500 fx loop is full with other pedals so it is not an option.

 

 

 

So far I have concluded the following:

I can use DT25+other amp as a regular amps without L6 link if I really have to, the way I have for years. Some FX to line A, some to line B outputs, works fine.

But I have noticed the sound of DT25 is noticeably better using L6 link (which is logical since it uses one AD conversion stage less) and I would like to use it that way if possible.

 

 

The questions:

1. Is the only proper way to use single DT25 (with HD500 via L6 link) with another secondary amp to use another DT25 or I could combine DT25 and some other non-DT amp via audio out as I would like?

 

2. What happens internally DT25-HD500-via L6-link combo when I manually override "combo power amp" mode with the "studio/direct" mode?  Is this ok or this would change the DT sound the wrong way? And the regular 1/4" unbalanced output for other non-DT amp?

 

Or the only way is to use it this way is without L6 link, just like a regular amp as I concluded even though the sound is not on the same level as L6 link?

I do want the best sound possible so it is a big issue.

 

 

And I do use HD500 preamps to single DT25 amp via L6 link for some other scenarios, so it is not wasted but that is another story :)

Thanks!

1. The "proper" way to use the DT25 with L6 link is to do everything in the POD, not to use the DT internal amps.  I think you would do better either with a second DT25 by L6 link or by not using the L6 link at all.

 

2.  Mine defaults to Stack Power Amp (DT Head) and I can't get it to Sudio direct with L6 link so I can't answer for you. 

 

Again, to use it as you do with effects only and using the DT25 as a standalone amp, just use the 1/4 outs and keep it in Studio Direct.  I am not sure why you say the sound is not as good.  That same signal quality is being passed to the other amp by 1/4 out and it sounds good right?

 

I've tried to figure out a good way to do it for a while now so I could send one signal to the DT and another to the PA but the output modes in L6 link always get in the way.  L6 is great for full integration but a PITA for some other configurations like the one you have...

Well I can switch it to "studio direct" manually, it surprised me as well. Maybe because I have no amp selected in hd500 and DT25 defaults to channel B? Will try that today again.

 

The sound not being as good as I reffered is adressing DT25 via 1/4" output versus L6 link. If you go HD500 - 1/4" audio out > DT25 you have one extra level of AD conversion. If you are already digital in the hd500 and go digital via L6 to DT25 the signal is better and I can feel this.

 

The other thing is if I go "studio direct" and 1/4" out to my other amp it is fine since it doesn't have AD converter and is all analog. If I use L6 link and hd500 switches to "combo pwr" mode it muffles this output and the sound sucks.

 

Will investigate further and report if I find a way but seems to me L6 link in dual amp mode will not be an option as well.

Thnx

Good news here!

 

After this weekends detailed testing It seems that this is perfectly doable :)

 

If you run your amps in hd500 "disabled" and DT25 over L6 link configures itself to "combo pwr" mode (and goes to B channel) it is exactly the same as "studio direct".

You can hear switch in audio signal every time when changing mode manually in HD500 - but the sound stays the same, probably because the amps/cabs in pod are off.

 

So I can safely run my other non-DT amp in the 1/4" R out and this way I can use both and use the highest quality sound I can out of DT and my other amp.

"Combo front" i "Stack front" mode don't work this way, they change the EQ so the 1/4" out is also changed.

 

I don't think any of this is possible with preamps on/cabs off in the pod though but I didn't test it this way since if I use preamps from the pod I want them ON anyway.

 

I hope someone finds this information usable.

 

Cheers!
