The preamp has balanced (TRS) 1/4" and XLR outputs, but the Alesis does not have a balanced 1/4" line input section, so use standard 1/4" TS cables. You can use TRS cables if you have them already, of course.
Don't use XLR to XLR cables as then you will be putting the pre-amped signal into the Alesis preamps.
