Connecting the speakers
Connecting the speakers cables
Carefully check the left (L) and right (R) channels and + (red) and – (white) polarities on the speakers being connected to the unit, and be sure to connect the channels and polarities correctly.
1 Peel off about 0.03 ft / 10 mm of sheathing from the tip of the speaker cable, then either twist the core wire tightly or apply solder to it.
2 Turn the speaker terminal counterclockwise to loosen it.
3 Insert the speaker cable’s core wire to all the way into the speaker terminal.
4 Turn the speaker terminal clockwise to tighten it.

When using a banana plug
Tighten the speaker terminal firmly before inserting the banana plug.
NOTE
•Connect the speaker cables so they do not stick out of the speaker terminals. The protection circuit may be activated if the wires touch the rear panel or if the + and – sides touch each other (vpage 21 “Protection Circuit”).
•Never touch the speaker terminals while the power supply is connected. Doing so could result in electric shock.

Speaker impedance
Use speakers with impedances within the ranges shown below to suit how they are used.
Speakers used | Impedance |
A | 4 – 16 Ω |
B | 4 – 16 Ω |
A and B | 8 – 16 Ω |
8 – 16 Ω |
Protection circuit
The protection circuit is be activated in the following situations:
•If the speaker cable wire touches the rear panel or screws or if the speaker cable wire touches the speaker cable’s + and – sides are touching
•If the surrounding temperature is extremely high
•If the inside of the amplifier gets hot to extended use at a
high output
If this happens, unplug the power cord, then check the connections of the speaker cables and input cables.
If the unit becomes very hot, wait for it to cool off and improve the ventilation around it. After doing this, plug the power cord back in.
If the protection circuit is activated even though there are no problems with the ventilation around the unit or in connections, the unit may be damaged. Turn off the power and then contact a marantz service center.
