Speaker Connections
Connect the speakers to the SPEAKER terminals using commercially available speaker cables.
Before making or changing connections, disconnect the power cord plug from the wall socket.
oConnect 4Ω or higher impedance speakers.
oDo not connect two or more amplifiers to one speaker.
oThe metal portions of the two separate wires should not touch or an electrical short can occur. Shorted wires can create a fire hazard or induce a failure in the unit.
o To prevent hum and noise, do not bundle the speaker cables together with the power cord.
Speaker cables
oUse the shortest speaker cables possible. As cables become longer, electrical resistance increases and damping characteristics are reduced. Moreover, inductance and capacitance also increase, degrading the quality of high frequency sounds.
oThe left and right speaker cables should be the same length.
oGenerally, the ¥ side of the speaker cable is marked to make it distinguishable from the ^ side of the cable.

How to connect
Be sure to connect each plug securely.
Using speaker cables with bare wire
Turn the terminal cap counterclockwise to loosen it. Insert the bare wire end properly into the terminal hole, and then tighten the terminal cap.
oDo not insert the insulation coating into the terminal hole. Insert only bare wire.
oThe thickness of wires should be 4 mm (1/8˝) or less.
oMake sure it is fastened securely by pulling the cable lightly.
Using speaker cables with spades
Turn the terminal cap counterclockwise to loosen it. Insert the spade into the terminal, and then tighten the terminal cap.
oThe inside diameter of spades should be 6 mm (1/4˝) or more and outside diameter of spades should be 13.5 mm (1/2˝) or less.
13.5 mm (1/2˝) or less
6 mm (1/4˝) or more
oMake sure it is fastened securely by pulling the cable lightly.
Using speaker cables with banana plugs
With the terminal cap tightened, insert the plug into the jack on the end of the cap.
oRead the instructions supplied with the banana plug.
For European customers
In accordance with European safety regulations, it is not possible to connect banana plugs into the speaker terminals on European models. The holes into which banana plugs are inserted have been covered with black caps. Connect the speakers using spades or bare wires. If the black caps become separated from the terminals, return them to their original position.
