From the Commander

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).

Be sure to read before performing the automatic

measurement.

• The automatic measurement should be performed in a quiet place

with the engine, air-conditioner, and heater turned off. If a mobile

phone or car phone is installed in the vehicle, move them outside of

the cabin, or turn the power off. Sound other than the measuring

sound (ambient noise around the vehicle, engine noise, and

ringtones) may interfere with measurement, resulting in inaccurate

measurement of the acoustic characteristics of the cabin.

• 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 low-pass filter, turn off the low-pass filter

of the power amplifier to make measurement. The low-pass filter in

the powered subwoofer or the power amplifier for a subwoofer

should be set at the highest cutoff frequency.

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.

Turning ImprintEQ On/Off

ImprintEQ setting is performed on a PC. The commander can only

switch the ImprintEQ memory settings.

Press and hold [FUNC.] for at least 2 seconds.

The memory setting switches with each press.

ImprintEQ 1 ImprintEQ 2 ImprintEQ OFF

ImprintEQ 1

ImprintEQ 1/ImprintEQ 2: ImprintEQ ON mode

• 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.

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.

Press [FUNC.].

Rotate the [Rotary encoder] to select “Sound Field

Adj.,” and then press the [Rotary encoder].

Automatic

Measurement

Function

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.
