Installing Your Speaker System; Connecting The Speakers - Pioneer VSX-LX70 Operating Instructions Manual

Connecting your equipment

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 71 if you plan to
use speakers with an impedance of less than 8 Ω).
