Sony str-da4400es Guia Do Utilizador

Place the optimizer microphone at your 
seating position. Use a stool or tripod so 
that the optimizer microphone remains at 
the same height as your ears.

• When a subwoofer is connected, turn on the 

subwoofer and turn up the volume 
beforehand. Turn the MASTER VOLUME 
knob to just before the mid-point.

• If you connect a subwoofer with the 

crossover frequency function, set the value 
to maximum.

• If you connect a subwoofer with an auto 

standby function, set it to off (deactivated).

Depending on the characteristics of the subwoofer 
you are using, the setup distance value may be 
further away from the actual position.

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 
even if you continue to use the receiver with 
that value.

The auto calibration function allows you to 
measure the following:
• Speaker connections

a)

• Polarity of speakers
• Speaker distance

b)

• Speaker size

b)

• Speaker level
• Frequency characteristics

c)

a) This receiver corrects signals by analog 

downmix processing only for the center speaker 
and subwoofer when the multi-channel input is 
selected. The correction is invalid for other 
speakers.

b) The measurement result is not utilized when the 

multi-channel input is selected.

c) • Signals with a sampling frequency of higher 

than 96 kHz are always played back at either 
44.1 kHz or 48 kHz.
