Measurement sequence for the automatic measurement functions
Perform the automatic measurement in the following sequence.
When ImprintEQ is used:
First, ImprintEQ, then RoadEQ.
When ImprintEQ is not used:
First, AutoTCR, then RoadEQ.
•When ImprintEQ is used, AutoTCR is not required.
•When ImprintEQ and AutoTCR are performed after RoadEQ, re- perform RoadEQ.

Before Performing Automatic
Measurement
This unit is equipped with ImprintEQ, RoadEQ, and AutoTCR as automatic measurement functions.
•The Commander cannot set ImprintEQ setup. Refer to PC Operation Section “Setting ImprintEQ” (page 17).
WARNING
•Do not perform automatic measurement while the vehicle is running.
Do not perform automatic measurement while the vehicle is running. Automatic measurement requires microphones to be installed in the cabin to measure acoustic characteristics, and the speakers may output loud noise for measurement. This may interfere with safe driving and lead to an accident.
Be sure to read before performing the automatic measurement.
•The automatic measurement should be performed in a quiet place with the engine,
•Be aware that the battery may be drained if you use the unit for an extended period of time without running the engine.
•The microphone supplied with this product is specifically designed for this type of measurement. Use of any other microphone will give poor or no results. Use of microphones other than the one supplied is not recommended.
•If the system is equipped with a power amplifier with input level control or a powered subwoofer, the measurement may not be possible if the input level is set low. However, to perform correct measurement, the input level should not be set too high.
•For a power amplifier with
Turning ImprintEQ On/Off
ImprintEQ setting is performed on a PC. The commander can only switch the ImprintEQ memory settings.
1 Press and hold [FUNC.] for at least 2 seconds.
The memory setting switches with each press. ImprintEQ 1 ImprintEQ 2 ImprintEQ OFF ImprintEQ 1

•Memory settings that do not include ImprintEQ measurement data are skipped.
•For further details on ImprintEQ, refer to PC Operation Section “Setting ImprintEQ” (page 17).
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.
1 Preparing for measurement.
•Park the vehicle in a quiet location.
•Close doors, windows, sunroof, etc.
•Turn the
•Turn off the engine of the vehicle.
2 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.
3 Turn the ignition switch of the vehicle to ACC (On).
•If an
