Then they're bonkers quite frankly
The wiring would be the same as the diagram above, just lose the XLR feed.
i might be wrong, it is a very nice bass amp and cab though so i think they just want the sound from that, it is probably loud enough to barely need miking up anyway. it would be a shame to not use the expensive gear when i have the chance. i can always use th sansamp the other 95% of the time whn i have shit gear
