3: Connecting Speakers - Sony STR-DB780 Operating Instructions Manual

3: Connecting speakers

Connect your speakers to the receiver. This receiver alows you to use a 5.1 channel speaker system.
To fully enjoy theater-like multi channel surround sound requires five speakers (two front speakers, a
center speaker, and two surround speakers) and a sub woofer (5.1 channel).
Example of 5.1 channel speaker system configuration
Front speaker (L)
Active sub woofer
Tip
Since the active sub woofer does not emit highly directional signals, you can place it wherever you want.
Speaker impedance
To enjoy the best possible multi channel surround, connect speakers with a nominal impedance of
8 ohms or higher to the FRONT, CENTER, and SURROUND terminals, and set the IMPEDANCE
SELECTOR to "8 ". Refer to the operating instructions supplied with your speakers if you are not
sure of their impedance. (This information is often on the back of the speaker.)
Alternatively, you may connect speakers with nominal impedances between 4 and 8 ohms to any or
all of the speaker terminals. However, be sure to set the IMPEDANCE SELECTOR to "4 " if you
connect even one speaker with a nominal impedance between 4 and 8 ohms.
Note
Be sure to turn the power off before adjusting the IMPEDANCE SELECTOR.
