Does Toplogy Matter When Using A Hd500x With Dt?

I've got my new rig tongether and just now getting to play around with it. I love this rig. Variax500 VDI to HD500x w/ L6link to DT25 combo. 

 

I've been using the "Pre" models along and setting No cab as it seem logical to let the DT25 combo have it's sound on the cab. I noticed the weeked that during a performance I had way too much reverb in the sound. I turn my reverb off on the HD500x but it was still there. Then I noticed I had left the reverb knob up on the DT. So I reached around and zeroed it, problem was solved. But it got me to thinking althought I know the knobs are sync'ed the reverb seemed to have largely be coming from the DT when I had too much. Does this apply to some extent to the DT as well?

I see in the "HD Edit" software you can cofigure the power amp to be what ever you want if you want to tweak the sound way from the original. But I also see you can set the Topology as well. I've been leaving this to "I". Since the HD500x is providing the Pre amp model does setting the toplogy even matter?

they decoupled the reverb to a degree with the pod/dt combo... in part to give you more available DSP on the pod... because you can do that entirely on the DT.

 

just FYI though... all the models in the pod etc... are based on specific cabs... there is no model that has a "no cab" default...

if you like what you're hearing... great....

but if you're AC30 doesn't sound like an AC30... that's probably why (or whatever model....)

 

the topology will matter... although its not really topology in that instance anymore (topology is basically standalone terminology)

when used with the pod pre's it's basically how you want the REAL power amp to work... (when using the pre's the power amp is NOT modeled)

switch to the various default pre's in a blank patch and watch the topo light change...

you'll notice that certain amp tones are built on certain power amp configurations....

you can stick with the defaults or change it to build a custom tone.

Okay, that makes sense with the Reverb and could be actualy useful as it would be kind of global so I could dial just a bit into the Channel A and then no matter what patch I use it will have touch of reverb to accomidate the room.

 

On the Cab, so the DT is supposed to model the Cabs as well? Didn't know that I figured it would be cleaner with "No Cab" setting. I did notice the defaults all include one. But getting a 1x12 to sound like a 4x12 just don't seem like it's gonna happen at the actual speaker itself.

 

Below you can see the Topogly setting I'm referring to.  I can see where I can change the power amp Class to A/B or A and I can see that on the DT as well when it defaults in choosing a Amp. Using the DT by itself chaning that basically changes switch basically changes the pre-amp I'm using and brings in the defaults for the power amp.  So when using a HD500x it should default that approprately to setup the other settings? All I've seen it use was "I" but I have not dug greatly into yet, only used the Solo SLO100 overdrive, and bassman for custom patches yet.I would have thought the SLO100 would have settings closer to the IV setting as far as the rest of the setup.

funny thing is the topology switch on the DT does not control topology!  It selects the amp/cab/mic model for the channel based on what you have configured, either default from the factory or custom with DT Edit software.  However, the topology setting in HD Edit actually controls the physical negative feedback loop settings in the DT power section.  There is a world of difference between them.  

 

You really should just load up a few default pre models in HD Edit and play them while sampling the different topologies.  Personally I love lll more than the others.  I don't care that it is not the exact model the way it was built, I prefer the ragged edges it seems to give.  Then again I don't play a lot of pure clean stuff...
