I've always gone straight into the board mono from the XLR outs my HD500 and last thursday at practice on my helix. it works great it's quick simple and easy plus your sound guy will love the nice hot signal.
Yeah I knew they were the same. I've been a loyal customer to MF and the used to be much ore personal with their customers but now not so much I'll go with my local family shop and Sweetwater from now on.
