I have my Kemper currently running into a Mission Engineering Gemini 1 Powered Wedge. I am using one of the Kemper XLR outputs (Left) to the only input on the Gemini. Question 1. Can I use an XLR splitter type cable to use both Left and Right outputs from the Kemper to the sole input on the Gemini. Question 2. The Gemini has an output that you can use to connect an additional Gemini. Can I connect a passive 4x12 cab to this output?
