Getting my routing figured. Help me out dudes!

[BtsBassPlayer]

I am gonna get another sansamp bddi for live use.

Im running a RBI now so currently I am sending the signal straight from the RBI to the board ( as it simulates a full 8x10).

But if i remove the rbi and replace it with the bddi , how should i connect it to my ampeg b2re head to ensure the colored tone that im getting to my cab, from the BDDI, is the same tone going to the house?

The b2re has a xlr out as well.

Or how would you approach this situation?

If you're looking to use the BDDI as a preamp, try running 1/4" cable out of the BDDI and into the power amp in on the back of the amp. Then, run your XLR cable just as you would from the RBI. This should work, if the BDDI has enough output to drive your amp.
