Installing your speaker system
To take full advantage of the receiver’s surround sound 
capabilities connect front, center, surround and 
surround back speakers, as well as a subwoofer. 
Although this is ideal, other configurations with fewer 
speakers—no subwoofer or no center speaker, or even no 
surround speakers—will work. At the very least, front left 
and right speakers only are necessary. Note that your 
main surround speakers should always be connected as 
a pair, but you can connect just one surround back 
speaker if you like (it must be connected to the left 
surround back terminal). You can use speakers with a 
nominal impedance between 6 
Ω to 16 Ω (please see
Switching the speaker impedance on page 60 if you plan 
to use speakers with an impedance of less than 8 
Ω).
Connecting the speakers
Each speaker connection on the receiver comprises a 
positive (+) and negative (–) terminal. Make sure to 
match these up with the terminals on the speakers 
themselves.
Caution
• 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.
