Sound Adjustment Mode

Automatically adjusting the equalizer mode (Auto EQ)

You can measure the frequency characteristics (value) in the vehicle to automatically adjust them to the smooth characteristics with low distortion based on the measurement data if the optional measurement microphone (MEI-100) is connected to this system. The measurement result can be referred to when adjusting the parametric equalizer.

Adjust Time Alignment (Time alignment adjustment (Time Alignment)) and Crossover (Crossover adjustment (X-Over)) before measuring frequency characteristics.
When measuring frequency characteristics, Loudness setting is automatically cancelled.
Close all doors and windows while measurement is in progress.

In order to make the measurement of frequency characteristics easier, slight errors may occur in the measurement data under some circumstances when this function is used. In addition, it is not equivalent to the precise measurements that can be made by specialist measuring devices.

Measuring frequency characteristics

Connect the RCA connector of the optional microphone (MEI-100) to the L-CH of the AUX jack of the main unit.

Align the microphone with the actual ear position and attach it to the headrest or other appropriate fixture. (Attach the microphone using tape or string.)

Hold down the [ENTER] button on the PEQ screen for more than one second.

After pressing the button, a 10-second countdown begins. Leave the vehicle during that time.

After ten seconds, pink noise will be output from the speakers and the measurement of the frequency characteristics will start. The “Measuring" message appears on the display while measurement is in progress.

When the measurement is completed, a "COMPLETED" message will appear on the display. Then press the [Enter], [], [], [], [] or [/BAND] button to go back to PEQ screen and if necessary, adjust each band manually. "Auto EQ" displayed on the screen indicates that the measurement result is active. If the measurement is unsuccessful, a "FAILED" message will appear on the screen. In this case, go back to PEQ screen by pressing the [Enter], [], [], [], [] or [/BAND] button and repeat the process. You can cancel the measurement by pressing the [/BAND] button anytime during a measurement process.

The measurement result can be referred to when adjusting parametric equalizer.

Bluetooth is temporarily disconnected while measuring frequency characteristics.
