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.

• 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.
