Setup
Full Auto MCACC
Place the supplied speaker setup microphone in the listening position, measure
the test tones emitted by the speakers, then the unit automatically sets the
optimum volume level for each speaker, the crossover frequencies, and the
distance from the listening position. This also reduces the effect of the standing
wave in accordance with the viewing environment and automatically adjusts the
equalizers for the speakers and enables correction of distortion caused by the
acoustic environment of the room.
• Calibration takes between 3 and 12 minutes to be completed. The speakers
emit the test tone at high volume during measurement, so be careful of your
surroundings. Keep the room as quiet as possible during measurement.
• If you connect a subwoofer, check the power and volume of the subwoofer.
Set the subwoofer volume to more than half.
• If the power of this unit suddenly turns off, the wires in the speaker cables
have touched the rear panel or other wires, and the protection circuit is
working. Twist the wires again securely, and make sure they do not stick out
of the speaker terminals when connecting.
• If Full Auto MCACC has been executed, the speaker calibration made with
Dirac Live ( → p150, p154 ) is disabled.

3. Confirm a test tone is output from the subwoofer and press ENTER.
4. Press ENTER. Then, test tones are output from each speaker, and the
connected speakers and the noise in the surrounding environment are
automatically measured.
5. The measurement results in step 4 are displayed. If there is no problem in
the detection result of the speaker, select "Next" and press ENTER to output
the test tone again to automatically set the settings such as volume level,
crossover frequency, etc., to their optimum. (The test tone is automatically
output when 10 seconds has elapsed without any operation.)
• When an error message is displayed or when the connected speakers
cannot be detected, perform re-measurement by selecting "Retry" and
pressing ENTER.
• When it cannot be resolved by performing the re-measurement, confirm
if the speakers are connected correctly. If there is any problem with the
speaker connection, perform the connection after disconnecting the power
cord.
6. Once the measurement is completed, it is possible to perform the
measurement in 8 additional listening positions. To perform the measurement,
select "Next" and press ENTER, then follow the instructions. To not perform
the measurement, select "Finish (Calculate)" and press ENTER.
• After each listening position is detected, select "Finish (Calculate)" and
press ENTER to complete the detection process.
7. Disconnect the speaker setup microphone.
