Russound ABus only one left side speakers working
We have a Russound A bus system and with Ak-3 amp keypads and Ah484 hub. We built 2 1/2 yrs ago and we have two keypads installed but weren't using yet until we finished our decks. Yesterday we attempted to install 2 Bose outside speakers and connect them through the keypad, but we could only get one speaker to work. We know it is not the speaker as we swapped them and tried both. We also know that it is not the speaker output on keypad because we could get each of the L/R to work just not both of them at once.
Crazy thing is after getting frustrated with that we attempted to use the system in other areas of house later that day and only the left side speakers work throughout the house. No right speakers work now anywhere. Very frustrated. Does anyone have any ideas? Any help would be appreciated.
