I bought home cinema Yamaha equipment. I have difficulty with setting up the speakers with the RXV465. I followed the instructions I cut the cable and I put the wire into the speakers. However, in the amplifier there is only centre, surround left and surround right. But to get the front left and right working you need to put a banana cable. The boxset never contained the banana cable and also the instruction manual set says you never use banana cable for the EU. What do I do?
