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 63 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.
