ENGLISH

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.

Tighten the speaker terminal firmly before inserting the banana 
plug.

• 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.

Use speakers with impedances within the ranges shown 

below to suit how they are used.

A

4 – 16 Ω

B

4 – 16 Ω

A and B

8 – 16 Ω

Bi-wiring Connection

8 – 16 Ω

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.
