• These speaker terminals carry 

HAZARDOUS LIVE voltage. To prevent 
the risk of electric shock when connecting 
or disconnecting the speaker cables, 
disconnect the power cord before touching 
any uninsulated parts.

• Make sure that all the bare speaker wire is 

twisted together and inserted fully into the 
speaker terminal. If any of the bare speaker 
wire touches the back panel it may cause 
the power to cut off as a safety measure.

Connect the 

PRE OUT outputs of the unit and 

additional amplifier to add a surround back or 
front height speaker.

• If the surround back speaker or the front 

height speaker is connected, set the Pre 
Out setting (see The Pre Out Setting on 
page 40).

• You can use the additional amplifier on the 

surround back channel pre-outs for a 
single speaker as well. In this case plug the 
amplifier into the left (

L (Single)) terminal 

only.

Make sure not to bend the cables over the top 
of this unit (as shown in the illustration). If this 
happens, the magnetic field produced by the 
transformers in this unit may cause a 
humming noise from the speakers.

• Before making or changing connections, 

switch off the power and disconnect the 
power cord from the AC outlet.

• Before unplugging the power cord, switch 

the power into standby.
