Thanks for your response, Bruno. So, just to clarify, I should be using a TS (mono) cable on the Master Audio Out, and NOT a TSR (stereo)? I like to connect my miniBrute to an effects box, a KP3, that takes RCA inputs. When using a mono to RCA cable, I see I get signal on both levels. But when using a stereo to RCA cable, I get signal on only one side (which was my problem originally).
