When connecting your speakers to the amplifier using bare wire, unscrew the red and black caps on the
binding post, be sure not to completely remove or unscrew the red and black caps. Strip back the wire
insulation 1/2” (13mm). Insert the bare wire into the hole that was revealed by unscrewing the binding
post cap. After inserting the wire into the binding post hole, screw the binding post cap down on the wire.
To reduce the risk of shock or damage to your amplifier, be sure that the wire connected to one binding
post does not come in contact with that of another.
