I tried that with my Octave V70SE and with the SE everything sounded right but the balanced was distorted. I was connecting a Meridian G08 to the Octave. I was trying to compare se to xlr without having to touch the cables and having both cables connected to the same source didn't work well in my case.
Using both the Balanced and Unblanced inputs
Would there be any issue if I used both the Balanced and Unbalanced inputs on a MC275V amp to run EITHER video (RCA) and Audio (Balanced) and use the switch to select which format I wanted to use at the time, to avoid the need to plug in and out every time I wanted to change between CD and TV?
