Studio Line Signal Splitter – Summing Mixer Hybrid Mixing

Customer request: The unit is a bit of a hybrid. It is a 1U rack. On the input side, I want the (A) input to be 1x stereo, and the (B) input to be 2x stereo (which will be summed to the output). Additionally, there should be a switch on the input side to select either the A or B input. The output is 1x stereo out, balanced TRS. So will be a Studio Line Signal Splitter – Summing Mixer Hybrid Mixing
