I just got my GT Brick today, and it's got a balanced XLR out. My other preamps use 1/4 inch out, which I plug right into a line-in on the E-mu Audiodock. What's the best way to plug the Brick in? Get an XLR-to-1/4 inch cable, or just go into the XLR mic input on the audiodock? As long as the +48V switch is off, the AudioDock's preamp is not influencing the signal from the Brick, right? Thanks!
