Auto speaker setup using the setup microphone
Preparations
With the setup microphone, the unit automatically sets the following.
DISTANCE : The unit measures the distance between each speaker and the seating area and corrects the sound delay in the
seating area. The maximum speaker distance for correcting the delay is 15 meters (45 feet).
POLARITY :
The unit checks the polarity of each speaker and, when the polarity is wrong, corrects it.
Select “CHECK NO ” in “Setting the unit against automatic polarity adjustment” (➔ page 38) before starting the auto
speak
er setup when you do not want the unit to adjust polarity automatically.
SIZE / LEVEL / FREQUENCY : The unit measures acoustic characteristics of the room including speaker characteristics (size,
speaker connection status, output
level and lowpass filter settings) and adjusts them.
Note
The setup microphone is sensitive to heat. Keep it away from direct sunlight and avoid placing it on top of the unit.
These settings remain effective after the unit goes off.
The setup microphone jack is for use with the setup microphone only. Do not connect other microphones.
The volume may reach an extremely high level when you repeat the auto speaker setup.
When
the auto speaker setup is finished, check the volume before starting playback.
Setting the connection status and adjusting the level are the only available adjustment for the subwoofer through the auto speaker setup.
Such factors as speaker types, room conditions and speaker placement may cause the unit to set speaker size,
lowpass filter frequency and other items differently for the same type of speakers or produce settings that differ from
the actual characteristics of respective speakers.
When sound from speakers seems odd, check the following settings. When you find undesirable settings, correct them
manually.
See “Setting speakers and their sizes”, “Setting distances” and “Setting the lowpass filter” (➔ pages
37 and 38).•
