HD500 w/ DT50 - Dual Amps A/B

Hey Guys,

 

I was messing with a patch I created for my HD500 DT50 setup, and ran into a snag maybe someone can help with.

 

On the HD500 I have a dual amp setup and wanted to A/B them on the patch (switch between the two within the same patch).   So logic would dictate I set a footswitch to turn on Amp A and turn off Amp B when the switch is pressed.  However, we know that when using a DT50 through Line6 Link, that when you turn off the amp modeling(amp A), the DT50 goes to channel B on the amp and channel B is ONLY controlled by the dials on the Amp itself.   Therefore, my "B" amp on the HD500 becomes redundant and does not work.

 

Is there any way to achieve this without channel B on the DT50 taking over?

 

I have solved the issue with a workaround, but it requires two extra FX blocks, by placing a volume pedal after each amp (independently) and have my 2nd Expression pedal turn these volume pedals on/off with a roll of my foot. And then of course, a third volume pedal is needed to have a master volume pedal.  However, i would like to just A/B the amps with a footswitch so I can free up the fx blocks, and my 2nd expression pedal.

 

I know this can be done without a DT50 (simple A/B).  Is there anyway to achieve this without the DT50 channel B taking over?  What am I missing?

    Re: HD500 w/ DT50 - Dual Amps A/B

    If I understand your question correctly, try this:

     

    Before you set the FX controls, have amp A on and amp B off, then set foot switch one to control both amp A & B to turn off via FS1.

     

    When you press FS1... amp A should now turn off and amp B should activate.

     

    hope this helps

     

    cheers

      Re: HD500 w/ DT50 - Dual Amps A/B

      Yes I know that.  I have it set that way.  However, when amp "A" turns OFF, and amp "B" turns ON,  the DT50 switches to channel B which isnt controlled by the POD,  so no amp model loads, just DT50's Channel B settings do. And since it's a Link connection, no post effects will be routed.

       

      Maybe just a limitation of the device in a link connection?

        OK...I see what you mean. You have a good question. The only work around I can see is to get 2nd DT50

          A 2nd DT50 would be nice!  I am working towards that!  Just had a newborn baby girl though and gotta save some cash right now.

            Congratulations!

             

            I know it's not the best solution but wouldn't connecting via the 4 cable method (instead of L6 link) allow you to A/B the tones and sill have pre and post effects? I've been thinking about trying this but don't have enough cables at home.

              Re: HD500 w/ DT50 - Dual Amps A/B

              Thanks!  She's incredible!  See attached

               

              Yea the four cable method is an option, but I'd rather not go that route just for this.  I can use the workaround I mentioned(multiple volume pedals), but just find it hard to believe this wasn't a thought by the Link developers..

               

              I suppose if I was a FS1-4 user only, I'd just have multiple patches and switch between them for leads and what not.  I tend to like pedal board mode (FS 5-8) where I have all footswitches enabled for effects.  I tend to stay on one patch for a variety of tunes, and tweak my sounds by effects and boosts.  My goal is to have a cleaner amp in A, have a stomp to drive it to a slight crunch, and then A/B to the B amp like a tread for some real meaty leads when needed.  Having them all on the same patch is nice for effects I'd like on at the time versus having to worry about switching to another patch and worrying about what effects are on or off on the second patch.   I suppose it could be carefully mapped out with different patches, but I'm more of a spontaneous player, and like to change what tones I generate based on the mood of the song at the time being played.  Therefore staying in the same patch and just tweaking effects, and A/B ing is where I'm most comfortable for my rig.

          Re: HD500 w/ DT50 - Dual Amps A/B

          Yep just treid panning both left, makes no difference.  Not sure why it would when as soon as you turn off Amp A the DT50 switches to channel B(which has no pod amp).

           

          I've attached the patch I am working with.  This patch is the workaround using volume pedals to achieve this.  I have set footswitch 8 to swap the volume pedals on/off status which achieves the dual amp a/b swistching.  But as you can see, I lost two FX slots going this route.  I don't know why I mentioned earlier my 2nd Expression Pedal was taken up by this config of a/b'ing, but it's not, I have FS 8 set for the A/B switch. 

           

          I can't believe the HD500 won't a/b two amps with a single DT50 hooked up via Link, but will if it's not hooked up to a DT50 via Link.  The problem lies in the Link code (if it's a problem).  It would be nice if the DT50 didn't jump to channel B if you had dual amps loaded in the HD500 (and only one DT50 connected), and only turned off Amp A, but left Amp B on.    Marketing trick to buy another DT50?   or oversight?  You decide..

    We can reproduce this here as well and honestly I'm not sure what's expected here.

       

      I've followed up with our QA department to see what they say. I'll keep you posted here. Thanks.

    RE: HD500 w/ DT50 - Dual Amps A/B

    I just wanted to chime in here to say that I am currently looking into this with Product development.  I experience the same ting you do and makes toggling between amps with a DT50 connected via L6 Link not work the way you expect.

        Re: RE: HD500 w/ DT50 - Dual Amps A/B

        I think it the right behaviour, see the L6 doc.

        I've copied a section out of it. Page 3.9

         

        DT50 Channel A & B Operation

        When any of the SETUP - L6 LINK:CONTROL AMP 1 through AMP 4 options are

        set to “AMP A” or to “AMP B,” the respective DT50 amp(s) will automatically switch

        between Channels A & B based on the POD HD500 Amp Model A or B’s On/Off state:

        • When the POD HD500 Amp Model is “On,” all respective DT50 amps switch to

        Channel A, and their controls operate in tandem.

        • When the POD HD500 Amp Model is “Off” (or set to “None”), all respective DT50

        amps switch to Channel B. The controls do not operate in tandem between the

        POD HD Amp Model & DT50 Channel B. When in Channel B, DT50 utilizes its

        own, internal Amp Modeling only.

        • When a DT50 switches to Channel B and multiple DT50 are connected, all

        DT50 amps sync to the Channel B knob and TOPOLOGY MODE, CLASS &

        PENTODE/TRIODE settings of DT50 #1.

        • While two DT50 amps are connected, all Channel B knob & Topology switch

        adjustments work in tandem between all DT50 amps. The Master Volume

        knobs remain independent on each amp.

        Likewise, when toggling the front panel DT50 Channel A/B switch (or the DT50 Channel

        A/B footswitch), the respective POD HD500 Amp Model A or B to which this DT50 is

        synced will toggle On/Off in response.

         

        Hope it helps

        - Hans

          Re: RE: HD500 w/ DT50 - Dual Amps A/B

          Yes that's the behavior for all scenarios except for when you have TWO amp models in your chain and one DT50 connected.

           

          The only internal programming logic that would be needed to correct this, is for example,

           

                IF (two amps selected in HD500 and one remains on) THEN

                       DT50 stay on channel A

                ELSE

                       DT50 change to channel B

                END IF

           

          So yes as the product manual states pretty clear what should happen to the DT50 when you toggle AMP A off.  But it fails to state what should happen when you toggle AMP A OFF and AMP B ON, and this is the problem.  No amp toggling within the same patch when using the DT50.

            Re: RE: HD500 w/ DT50 - Dual Amps A/B

            I think it states, that it turns to amp B on DT50, not to amp B on HD500.

             

            In other scenarios, two DT50's are connected and then it's is possible.

             

            My way around it is to 'use'/dial in' the DT50's channel B, another way around is to use two patches (I know not exactly the same thing as you want in one patch, but probably workable).

             

            I'm just trying to help.

             

            Kind regards

            - Hans

              Re: RE: HD500 w/ DT50 - Dual Amps A/B

              Sure I've got work arounds too.  I appreciate the suggestions though.  My workaround is to pop in two volume pedals, both set to 0 db.  Put one behind each amp in the chain, and program a footswitch to toggle one off, and one on.  This works as well.

              However, it just seems strange that it can't be managed by the Link connection to achieve what can be done with no DT50 connected.  It really is simple logic in the Link code to fix it.  They cover every other situation (one dt, two dt's, routing for each), it just seems the simple scenario was overlooked.    Which is why I asked the Line 6 poeple what they thought about this.  Apparently they are interested enough to look at or work on an answer.

      Re: RE: HD500 w/ DT50 - Dual Amps A/B

      Hi Line6Hugo,  I bought a DT25 and I was sure it was possible to switch between two different amp setting in the same patch by using Channel A and Channel B!!! I, my mind, this is one of the most appealing thing of the DT series: be able to switch between two different amp instantly... now I've learn that we only can do this by changing patches......   Since there was no update since april, I'm bringing this thread a bump to know if you will include this feature in the next update!!

    RE: HD500 w/ DT50 - Dual Amps A/B

    After hearing back from product development, the ability to toggle between two amp models while staying on Channel A (with different amp configuration settings switching for each amp model) on the DT50 amp when connected via L6 Link is not possible with the current firmware.

       

      For now, this is the expected behavior of the amp.

       

      We are currently looking into whether this can be implemented in a future update.

      Re: RE: HD500 w/ DT50 - Dual Amps A/B

      Hi Line 6 Hugo - was just googling ref this subject - I've got 2 killer amps (Boogies:  MkIV and Dual Rec) - and want to A/B them on stage - what's best way using my HD500...?  I currently use 4 cable method anyway, just with the Dual Rec, but want some of the clean/crunch sounds on the MkIV.

       

      Incidentally - I also get a horrible "cyclical" feedback when I use many of the amp sims (esp the heavier ones) when going through the Rec effects loop/  Paul Hindmarsh had a look on one of the demos but couldn't quite solve it...  Any ideas?

       

      Thanks,

    I'm a bit confused with how you set up a dual amp patch and when turning on modeled amp off, you get into DT50 amp channel B.  If you have two modeled amps, then turning one ff with the other still on, will not switch the DT50 to channel B unless you are not using two modeled amps, or you are turning both modeled amps off at the same time.  Or you have the second amp routed in such a way that it is not responding properly.

     

    I didn't bother to read all the posts between your first and this one.  If this has been said - great.  If it's not been brought up, then there is something wrong and it should be very obvious how this gear works to those who work @ L6 and those like myself who have been using it and know it inside and out that are not employed by L6.

     

    If you've not previously gotten a correct answer - you have now.
