Sony STR-DA5800ES Operating Instructions Manual page 47

Notes
• Depending on the characteristics of the subwoofer
you are using, the setup distance value may be
different from the actual position.
• If you perform "Speaker Settings (Auto
Calibration)" using the Easy Setup, the
measurement results will be overwritten and saved
on the currently selected position ("Pos.1" is
selected as the factory default setting).
Tips
• Depending on the position of the subwoofer, the
measurement results for polarity may vary.
However, there will be no problems even if you
continue to use the receiver with that value.
• Depending on the speakers, "Out Phase" may
appear even if there is no problem with the speaker
connection. This is caused by the speaker
specifications, and there will no problems even if
you continue to use the speakers.
When you connect two
subwoofers to the receiver
If you cannot obtain measurement results of
the "Auto Calibration" function correctly,
depending on the environment, or you want to
make fine adjustments, you can set up the
subwoofers manually. For details, see
"Speaker Setup" in the Speaker Settings menu
(page 97).
Notes on the speaker
impedance
• If you are not sure of the impedances of the
speakers, refer to the operating instructions
supplied with your speakers. (This
information is often on the back of the
speaker.)
• When you connect speakers all with a
nominal impedance of 8 ohms or higher, set
"Speaker Impedance" to "8 Ω." When
connecting other types of speakers, set it to
"4 Ω."
• When you connect front speakers to both the
FRONT A and FRONT B terminals,
connect the speakers with a nominal
impedance of 8 ohms or higher.
– When you connect speakers with
impedance of 16 ohms or higher in both
"A" and "B" configuration:
Set "Speaker Impedance" to "8 Ω" in the
Speaker Settings menu.
– For other types of speakers in other
configurations:
Set "Speaker Impedance" to "4 Ω" in the
Speaker Settings menu.

To use the receiver as a pre-

You can use the "Auto Calibration" function
when you use the receiver as a pre-amplifier.
In this case, the distance value shown on the
display may differ from the actual distance
value. However, there will be no problems,
