Connect the ‘+’ loudspeaker terminals to the red binding posts and the ‘ – ‘ terminals to the black binding
posts. There are three methods of connecting speaker cables to the binding posts.
1. Solder 4 mm banana-plugs to the ends of the speaker wires and plug into the center of the turrets.
2. Thread the stripped ends of the wires through the holes in the posts. Enter the wires for output
channels 1 and 3 from above and for channels 2 and 4 from below. Tighten the plastic turrets by
nger only, being careful not to overtighten.
3. Crimp 4 mm insulated spade terminals onto the ends of the wires and push into the binding post
assembly from above (Ch. 1 & 3) or below (Ch. 2 & 4). The hole in the post is ignored. Hand tighten
plastic turrets, being careful not to overtighten.
