    In 1 day, I will become the proud owner of a spankin' new B7K Ultra v2!! Very excited. My only problem, so far, is the 1/4" out doesn't carry the cab sim. I surmised the creator's purpose for the 1/4" out would be connection to an amp and cab, therefore obfuscating the need for the cab sim. However, I typically have a Radial JDI at the end of my signal chain for connection to the FOH and feel it adds some texture and roundness to my tone.

    I could remove the JDI from my pedal board and just go from the XLR out on the B7KUv2 to the FOH, but I'm just wondering if there's any way to connect the Darkglass to the JDI using an XLR-to-1/4" cable, but not sure that would work - impedance mismatch?

    You don't need the JDI at the end of your signal chain with the Ultra :thumbsup:



     
  3. Yeah you do, because a lot (the overwhelming majority) of soundguys would rather eat a rotten donkey carcass than use anything other than their cheap, no-brand DI's.

    OP, you could run an XLR-to-1/4 from the B7KU. You get your cabsim, and your/your sounguy's choice of DI, everyone wins

    I believe you would need a TRS 1/4 if you did. Someone correct me if I’m wrong.

    Based on Rane's Sound System Interconnection, I think it's either option 3 or 5 in Figure 4. The determining factor is whether or not the B7KUv2 uses a transformer or not.

    It is option 3,;) you might not get any sound with the ground lifted, however, so please make sure to take that into account.

    Kind regards,

  8. So no XLR-TRS 1/4? Even though the XLR is balanced?

    If you connect the DI output to a balanced TRS input then a regular XLR to TRS will work. For unbalanced connection you need to do this special wiring. Unfortunately this is not very well standardized.
     
  10. OK, will a regular standalone DI work fine with a balanced signal, and how will that work with a through output to an amp or poweramp?

    Actually, I must correct my previous answer, in theory both 3 and 5 from Sound System Interconnection should work, 5 should actually be easier: in theory an XLR to TS to a regular DI should work just fine.
     
  12. That's great, thanks Doug!

    I've been playing live for a very long time and have never been forced to use the soundguy's DI...maybe there is just a surplus of dead donkeys where you're from ;)
