Hullo, I feel a bit foolish. I've owned a lovely RSM 191 microphone for years, and tried to record some birds out my window, and the microphone easily overloads. Either I'm senile, or losing my sight, but I can't find the 10db attenuator referred to. I have looked all over the matrix switchbox, and the mike. I need to know I am not losing my mind, but I really need that attenuator. Help would help. Alun
