The Sound Field Optimization procedure fails (BRAVIA Theatre Quad, BRAVIA Theatre Bar 9, BRAVIA Theatre Bar 8)

If the Sound Field Optimization procedure fails, check the following depending on your situation:

When the Sound Field Optimization procedure fails during the speaker position measurement:

• Check the installation location labels on the bottom of each of the four speakers and make sure they are correctly located.
• Be sure to install each speaker upright so that the labels on the bottom of the speakers are directed downwards.
• Check the way the speaker is installed:
  • If a speaker is installed sideways, the Sound Field Optimization procedure can't be performed properly.
  • If a speaker is installed at an incline, the microphone used to measure the speaker is also inclined, and the sound measurement for the ceiling distance is output at that incline, which can cause the Sound Field Optimization procedure to fail.
• Perform the Sound Field Optimization procedure again, making sure the surroundings are quiet.
• Check the distance between the speakers:
  • Install the speakers at a distance of at least 50 cm (19 3/4 in). If the distance between speakers is too close, the Sound Field Optimization procedure can't be performed properly.
  • If the speakers are too far apart, move them closer to each other.
• If an obstacle blocks the speakers or the microphone used to measure the speaker, the Sound Field Optimization procedure can't be performed correctly. Remove any barriers between or in front of the speakers.

When the Sound Field Optimization procedure fails when using a microphone on a mobile device:

• Do not cover the microphone with any objects.
• Perform the Sound Field Optimization procedure again because something went wrong temporarily.
• If an obstacle exists between the speakers and the microphone or if the speaker is blocked, the Sound Field Optimization procedure can't be performed properly. Remove any obstacles between or in front of the speakers.
• Perform the Sound Field Optimization procedure again while you are inside the perimeter of the four speakers.
• Measurements are more precise when there are no reflective or echoing objects around. Avoid holding the mobile device on or over a table or, if there are curtains, close them before performing the Sound Field Optimization procedure.
• While measurement accuracy using a mobile device is limited, optimal corrections will be performed based on the information obtained to provide the best stereophonic sound possible with the device.
  Note: If the measurement accuracy is limited, the Viewing Position can't be performed from the remote control screen of the Sony | BRAVIA Connect app.
• If you own a BRAVIA™ TV and you want to use the Acoustic Center Sync feature, turn on the TV while performing the Sound Field Optimization procedure.
