I would like to connect a recently acquired Demeter VTBP-201s pre-amp to a Crown XLS-1000 power amp. On the rear panel there are: 2X unbalanced 1/4" outputs, as well as 1X balanced XLR output (or am I interpreting this incorrectly?) How would I go about connecting the pre-amp to the power amp? (Do I need 2X runs of short 1/4" to 1/4", or 1X 1/4" to 1/4" only?). This is my first pre to power setup, and the pre-amp manual didn't contain the information I need, so any help would be appreciated.
