There is NO option for questions regarding my AX2 212 so I have to send it this way and ask that it be routed to the correct technicians. 

     I want to use both of my AX2 2x12 speakers on my AX2 212 along with all four speakers on my marshall 4x12 cab.  How would I go about this without distorting the sound from either set of speakers.  I understand I can use the headphone out and still have it use the Line 6 speakers, but there would be no way of connectiong to my cab (other then using the headphone cable directly into my Marshall).  I DO NOT want to "darken" the sound of either set of speakers!!!  Is there a mono on my AX2 212 for one cable (one that is already on the back of the amp) and then the second cable running to my 4x12?  If so, what impedence would I use on the AX2 and the Marshall 4x12?  Is there the option of running both in mono and if so would I be utilizing all 6 speakers...furthermore, would the two combined speaker "sets" then run in a stereo mode? 

     Now, for my own personal note regarding this amp...Line 6 nor anyone else has EVER made an amp as good as this one.  There is currently NO amp in the current Line 6 "arsenal' that I would trade for my AX2 212.  I wish you guys still made them like this; quality is second to none...period!!!  Thanks.
