T4D... So by connecting an XLR cable between a POD HD and the DT50, you now have access of using all 16 HD models instead of the 4 on the amp. But rather than the PODs 16 full models, we give you the 16 preamp only models, which is the way to run it that way. You still have the ability to set Class A, AB, Pentode, Triode for any of the 16 models. When you recall that patch the amp gets it's power section reconfigured/rebiased in the analog realm based on the digital info send along that L6 Link. You also have access to all the M Class effects that are in the M13. You can also chain 4 DT50's for say a Wet/Dry/Wet rig or 2 stereo setups at once.
Now someone could say I like the coloring of studio direct mode into an amp. But I think 99% would only take the preamp model feed it to the amp and use the Bogner designed power amp to run it. There's an option to feed the power amp of a DT50 combo or stack, plus other configs like front of a combo or stack with EQ filters to shape tone.
When you connect the POD HD it overrides the models in the amp. If for some reason you setup a patch that has no amp model into the DT50, it will default back to the topology last saved on the DT50 amp.
Does that help?
