Hi there,
Which REL sockets did you use to connect your BAT?
If you want to use the VK-75SE's output, as recommended by REL, then you'll need to use the REL supplied cable, between your 75SE speaker sockets and the REL's UNBALANCED Hi INPUT.
If you would prefer to use your VK-30s output then you'll need a balanced XLR terminated cable of appropriate length to connect the VK-30's Line out to REL's BAL LO INPUT.
Cheers
Steve
