I just took delivery of my new DT 50 2X12 and POD HD 500!
Some may call me crazy, but I sold my Mesa Dual Rect Roadking head and my 1982 Marshall jcm 800 head to
make this purchase. I really wanted to downsize and still have a variety of great tones with simple controls. After spending only 10 minutes with my guitar straight into the amp, I'm feeling very good about my choice. I know it will only get better as I begin to create some custom patches on the HD 500.
Here are my questions:
1- Is there an advanced guide/manual for the DT 50 (I haven't found one)?
2- I was hoping to use the 2 speakers in the amp and drive my Mesa 4X12 recto cab as well. The Pilot's Guide says
I should only use one of the speaker outputs at a time. I was hoping to have the open sound of the open back
combo and the low end punch of the closed back 4X12 at the same time. Will this work?
wow, you sold some nice amps... i would kill for those, BUT me thinks you wont be sorry once you get to grips with the DT50 and HD500
1. there's not really much to the DT50 amps... most of the advanced things are done with the HD500. manuals are here: http://line6.com/support/manuals/
2. well it's possible, but that depends on your mesa cab. it doesn't mean you can only use 1 speaker socket on the DT50, if you look at the back of it, the outputs are grouped into sections. a 4 ohm section, an 8 ohm section, and a 16 ohm section. you can only use 1 of those 3 sections at a time, BUT you can use all sockets in one of those sections together...
Now, off the top of my head I do not know what ohms the speakers in the 2x12 are. i think they're a pair of 8 ohm units, wired together to make a single 16ohm load. so if your mesa cab can be used as a single 16ohm mono cab (look on the back of it, and it will tell you)... then using a pair of 16 ohm loads (1 load is the mesa cab, the other is the speaker load from the dt50) that gives you a total load of 8 ohms, so you'd connect both to the 8 ohm outputs on the dt50... just remember when you disconnect the 4x12, you should plug the internal speakers back into the 16ohm slot...
Now if I'm wrong about the dt50 speakers being a 16ohm load, please don't try what I said and come back and let me know.

So let me get this straight. The 2 speakers in the dt-50 212 are indeed 8ohm/each. SO if I had another cabinet that is also 2 speakers @ 8ohms/each. I would connect plug that cabinet into the 8ohm slot and plug the dt-50 speakers into the other 8 ohm slot? But if just using the dt-50 load it would be plugged into the 16ohm slot?
This whole thing confuses me haha....

I hope this will help...
OHMS are done BACKWARDS in the sense of logic. In the true sense of resistance, it does make sense why things are the way they are.
So it goes like this 16 ohm cab x 4 = ??? Answer.....4 ohm total load
8 ohm cab x 2 = ??? Answer....4 ohm total load
Is anyone seeing a pattern here? How you work out ohm loads is you take the EACH speaker impedance 16/8/4 ohm, whatever - THEN you DIVIDE instead of multiply to get the total ohm load.
Now to add a bit more confusion to the mix - this formula is ONLY for PARALLEL speaker connections, NOT SERIAL connections which is exactly the opposite in results.
However, please note that the 2x12 DT50 comes with TWO speakers which take up TWO of the slots in the 8 OHM TOTAL LOAD section on the back.
If you have a 4x12 cab that can be a TOTAL of EITHER 8 ohms or 16 ohms, you then MUST USE the 4 OHM section and connection that external cabinet there along with only ONE of the 2 12s in the 2x12 combo unless you get a simple 1/4" "Y" cord and connector BOTH internal speakers onto one plug, then you can have the external cab and the two internal speakers.
If anyone needs further explanation between parallel and serial speaker wiring to hook up more or less speakers, please give me a shout. Or just type into a search engine either parallel speaker wiring, or serial speaker wiring. I'm certain there would be a few good sites with diagrams of the wiring I'm describing.
