NOTE
• Disconnect this unit’s power plug from the power outlet before connecting the speakers. Also,
turn off the subwoofer.
• Connect so that the speaker cable core wires do not protrude from the speaker terminal. The
protection circuit may be activated if the core wires touch the rear panel or if the + and – sides
touch each other ( vpage 151 “Protection Circuit”).
• Never touch the speaker terminals while the power cord is connected. Doing so could result
in electric shock. When the “Setup Assistant” is running, follow the instructions in the “Setup
Assistant” screen for making connections. (Power is not supplied to the speaker terminals while
the “Setup Assistant” is running.)
• Use speakers with the speaker impedances shown below.

it.
