When selecting the internal speaker outputs for my RS520 (front speakers) I also need to select the line outputs to supply an audio signal to an external amplifier for back speakers. This I can do if the line output level is at its lowest setting BUT if I change the output level to 2 volts which is what my amplifier needs, then the internal speakers are automatically unselected. It seems that at anything but the lowest output level, the RS 520’s RCA speaker outputs are automatically turned off. Is this a bug or a feature? Can it be fixed?
