Set the microphone at ear height as in the

actual listening position. Use a stand or tripod
to position the microphone.

Notes:

• Remove any obstructions between the speakers and

the microphone.

• Keep the room quiet during measurement.

• The test tone emitted during measurement is loud.

Take considerations for neighboring homes and
children.

• Step away from the listening position during

measurement and operate the unit with the remote
controller from outside the speaker path.

When the surround back speaker is set to NONE in
