Can anyone assist with this. Just bought a new XLS602. I would like to know if the following is possible. I want to take a [one] line from one of my auxillary sends of a Yamaha powered mixer - [jack]. I would like to split that line to the 2 canon inputs of the XLS. I an using 2 JBL Jrx 115 [8 ohms] out of the XLS - one per channel. I have 2 "aux sends" on the Yamaha and I want to use the other one for a powered foldback. Thanks.
