Adjusting the Time Correction

Automatically (Auto TCR)

A vehicle poses a unique listening environment. Speaker distances vary

widely to each listening position. These special conditions can be

overcome using the included microphone and the powerful

measurement system in this processor. The processor measures and

analyzes data automatically to optimize time correction for each speaker

and listening position selected.

Preparing for measurement.

•Park the vehicle in a quiet location.

•Close doors, windows, sunroof, etc.

•Turn the air-conditioner and heater OFF.

•Turn off the engine of the vehicle.

Preparing the microphone.

Place the microphone at the listening position (driver’s seat,

etc.). A camera tripod is recommended for this purpose.

•The microphone should be placed at shoulder height.

•When you save the measurement data values for various listening

positions in the preset, you can easily load one of them as necessary.

Turn the Ignition switch of the vehicle to ACC (On).

•If an air-conditioner or heater is turned on, turn it off. Measurement

should not be performed if air-conditioner or heater noise is present.

Click [Auto TCR] for [Shortcut] tab in the main menu.

The Automatic Measurement tab screen will be displayed.

•When you click [Automatic Measurement] in the Function switching

tab, the Automatic Measurement tab screen will also be displayed.

Refer to “Operating the Function Switching Tab” (page 7).

Click [Setup] for “Auto TCR.”

When the confirmation message is displayed, check

the content and click [OK].

When the confirmation message is displayed again,

check the content and click [OK].

Click [START] in the measurement start screen.

Countdown will start.

During the 10 second countdown, go outside the vehicle

and close the door.

A test signal will be output from the speakers to measure the

acoustic characteristics of the cabin. Do not open any

doors until the finish message appears on the screen. If

external noise interferes with the measurement. If the error

screen is displayed, perform the measurem ent again.

•If you want to stop measurement, click [CANCEL].

•If no microphone is connected, a confirmation message will be

displayed and measurement will not be carried out. Click [OK] to

cancel the indication.

When a confirmation message for closing the screen

is displayed, click [OK].

•To enable this function, Defeat should be is set to ON.

•Measurement of Auto TCR takes approximately 5 minutes.

•Auto TCR measurement result overwrites the manual TCR

measurement result.

•Sound may arrive at the listening position at slightly different times,

depending on the speaker and enclosure. To compensate for this, the

distance can be adjusted to be larger than the actual distance.

•After the setting, it is recommended to store the setting contents on

the unit. For details, refer to “Storing the Preset Values (Preset

Store)” (page12).

Adjusting for Road Noise (RoadEQ)

RoadEQ (REAL-TIME OPTIMIZED ADAPTIVE DRIVING EQ) is a

function to automatically adjust the EQ properties in accordance with

the road noise while driving.

The Road Equalizer compensates for constantly changing noise, so

always keep the microphones connected.
