To the best of my knowledge, edit was made in post 12 by adding word 'receiver'. No edits in Post 14.
'Sunday morning, as i power on the system, the speakers gave 'static/low pitch sound' and receiver shut-off '.
Will try mixing sub with 'Y' connectors. i guess beyond mixing, we will be hitting rock-bottom.
Don't know if this has got anything to do with receiver.
