Thanks for your help in steering me along the path of knowledge.
I have an Alto S12 mixer, but also have the Roland XV5050 module into the mixer stereo, plus a Behringer Virtualizer DSP2024P into Aux. The equipment I am now trying to fit in is the Yamaha VL70-m wind sound module. This latter module is a mono sound but the manual states to use stereo connections.
