Performing Initial Setup Operations - Sony STR-DB1070 Operating Instructions Manual

Speaker system hookup (continued)
Tips
• You can connect an active sub woofer to either of
the two jacks. The remaining jack can be used to
connect a second active sub woofer.
• To connect certain speakers to another power
amplifier, use the PRE OUT jacks. The same signal
is output from both the SPEAKERS jacks and the
PRE OUT jacks. For example, if you want to
connect just the front speakers to another amplifier,
connect that amplifier to the PRE OUT FRONT L
and R jacks.
2ND ROOM hookup
(STR-DB1070 area code U, CA only)
You can use the center and surround back
speakers as right and left speakers in the 2nd
room (See page 27). Make sure to connect
correctly as indicated on the rear panel.
Tip
When outputting the sound in the 2nd room, the
source signal for the 2nd room is output from PRE
OUT CENTER and SURROUND BACK jacks.
Speaker impedance
To enjoy multi channel surround, connect front,
center, surround, and surround back speakers
with a nominal impedance of 8 ohms or higher,
and set the IMPEDANCE SELECTOR to
"8Ω". Check the operating instructions
supplied with your speakers if you're not sure
of their impedance. (This information is
usually printed on a label on the back of the
speaker.)
You may connect a pair of speakers with a
nominal impedance between 4 and 8 ohms to
all of the speaker terminals. However, even if
one speaker within this range is connected, set
the IMPEDANCE SELECTOR to "4Ω".
Note
Be sure to turn the power off when setting the
IMPEDANCE SELECTOR.

Performing initial setup
operations
Once you have hooked up the speakers and
turned on the power, clear the receiver's
memory. Then specify the speaker parameters
(size, position, etc.) and perform any other
initial setup operations necessary for your
system.
Tip
To check the audio output during settings (to set up
while outputting the sound), check the connection
(see page 24).
Clearing the receiver's
memory
Before using your receiver for the first time, or
when you want to clear the receiver's memory,
do the following.
This procedure is not necessary if the
demonstration activates when you turn on the
power.
1
Turn off the receiver.
