Than you for the response.
The wires are labelled "front right" "front left", "rears" and shelf unit. In the room, I see 2 speakers on the front wall, and 2 in the ceiling at the back of the room.
What sort of (entry level) receiver would I need? Should it be a 3.1, 5.1, 7.1?
Also, what should I look for in a receiver?
(please pardon me, I am {very} novice in this field.
Thanks
