SPEAKER CONNECTION
Two speaker systems, A and B, can be selected individually
or simultaneously by means of the front panel SPEAKERS
selectors.
Note that no sound will be heard if only one of the speaker
systems is connected and the SPEAKERS selector A and B
are depressed.
Speaker impedance and power capability
This receiver is designed to work best with speakers having
nominal impedance from 8 to 16 ohms, and rated at 80 watts
(STR-AV780) or 110 watts (STR-AV880) minimum RMS per
channel with an 8-ohm load from 20 - 20,000 Hz. Be sure not
to use speakers, with impedance less than 8 ohms and to
use adequate power handling capabilities.

POWER SOURCE CONNECTION
Polarity of the AC power cord
A white mark is visible on one lead of the power cord and
one plug is larger than the other. This will help you align the
AC power cord polarity with the AC outlet polarity in order to
operate the receiver and other components in the system “in
phase”.
The larger plug of the AC power cord of the receiver should
be inserted into the negative potential of the polarized AC
outlet. This plug cannot be inserted into the unpolarized AC
outlet.
AC outlets (switched)
Equipment consuming up to 100 watts can be connected to
these outlets.
These outlets are controlled by the front panel SYSTEM
POWER switch.
Caution
Do not connect any electrical home appliance such as an
electric iron, fan, TV, video cassette recorder or other high-
wattage equipment to these AC outlets.
