Hi all need help hooking up a DBX 1231 to the LS25 all XLR.Should I use the pro.or monitor inputs,and could you tell me the connections  .I''m loosing my hearing ,hate to add the eq.Thanks Dave
I think you want to use the tape loop. The ARC tape out should go to the EQ input, and the EQ output should go to the ARC tape monitor input. This will engage the EQ when you set the ARC source to tape input.
