10. Step 7 - Preparing the Vehicle & Microphone
1) Ensure that all seats are in the proper position for the driver. If speakers are installed in the door empty the door compartment.
*Notice: The measurement results may improve when the front headrests are removed before measurements. In case the car is equipped with active headrests, don't attempt to remove them.
2) Attach the microphone to a camera tripod, using the pre-threaded nutsert
Notice: Make sure the microphone is
connected to the PXA-H100

11. Keep silence
Notice: The measurement area must be absolutely quiet. Every noise can degrade the performance. Stop the engine, switch the air-condition and the fan off. Close the doors, windows and sunroof while measuring.
In this case...silence is golden...

12. Step 8.1 – Start the latest Program Version 2.10
Connect the PXA-H100 to your Computer
Start PC Programm
Select PXA-H100

13. Step 8.2 - Listening area Selection

Place the microphone in the Driver’s Listening Position
Notice: Place mic at normal ear height, centered approximately 5,0 cm in front of the headrest position.
*Notice: Microphone MUST be pointing straight up
2) Exit the Vehicle and Close ALL Windows and Doors.

15. Step 8.4 - Measuring Position 1
Double-click ‘Measure’
Notice: The first measurement takes a long time, approximetly 10 minutes. It´s the most important measurement. There will fixed the levels crossovers, gains, timedelay. And the software will check which speakers are connected as well.
The software shows always the status and the options.

16. Step 8.5 - Measuring Position 1
The measurement starts:
Notice: You should hear a series of Logarithmic Chirps coming from each speaker: Driver seat front, passenger seat front, passenger seat rear, driver
seat rear, and then sub left and right. The chirp starts very quiet and gets louder and louder
Chirp Order: 1,2,3,4,5,6 1 2 4 3 5 6
When the first measurement is
You can read which speakers are detected. It´s not a problem to make a measurement without a rear system.

17. Step 8.6 - Measuring Position 2
Move the microphone to the rear center Position
NOTE: Place the microphone at normal ear height, centered approximately 5,0 cm in front of the headrest position.
2) Exit the Vehicle - Close ALL Windows and Doors
3) Double-click ‘Measure’ to begin measuring Position 3.

18. Step 8.7 - Measuring Position 3
Move the Microphone to the co driver side Listening Position

3) Double-click ‘Measure’ to begin measuring Position 6.

22. Step 8.11 - Finishing MultEQ
After you have finished all 6 measurements double- click
Notice: a minimum of 3 microphone measurement points are required. Our recommendation is 6 positions. The result will be much better.
IMPRINT Sound Manager will now display the MultEQ results. You can see the curve before and after MultEQ has done the calculations. The basic setting is the REFERENCE Curve.
Double-click to select your preferred curve.

23. Step 8.12 - Selecting a Target Curve
Select one from the 3 available ‘Target Curves’
Notice: Each ‘Target Curve’ is similar to choosing a shape for your over-all EQ settings on a classic EQ. Choose the curve that best suits your customers needs.
2) Confirm your choice by a double click on the OK button
3) Double-click when you have finished

24. Step 8.13 – Save Permanently
After selecting the Target curve choose the preset. If you want to save a second target curve choose another curve like in step 8.12 described.
Confirm by double-click
Now all seetings are saved permanently.

25. Step 9 - Exiting IMPRINT Sound Manager
Disconnect USB cable and the microphone from PXA-H100 and Computer X X
When the microphone is disconnected the display shows “Please push any key” Follow this instruction and you are ready and can enjoy the IMPRINT Sound

26. If the Sub is not loud enough, you can adjust the Gain for the Sub amp
Step 10 - Fine Tuning
If the Sub is not loud enough, you can adjust the Gain for the Sub amp
You can do some fine tuning BASS/MID/High on the headunit

27. Our experience with MultEQ
First, MultEQ can not work wonders. The installation is still an important part of a good Audio system.
If you have a good result before the MultEQ measurement, the difference between ON/OFF won´t be so impressing.
If you have some Phase Problems MultEQ will change the phases but you don´t see that and the software makes no comment.
Sometimes you have some level differences. The reason is the strategy of MultEQ. Attenuation has prority to amplification.
To make two passes with different conditions is not possible. For example one measurement for the driverseat (6 Positions) and the second for all front passengers.
When the measurements are done well, the tonale balance, attack, and soundstage will be much improved.
Sometimes you can improve the result when you try a different microphone position. If you put the microphone closer to the midrange may you have more midbass. It depends on the system setup.

28. How to demonstrate MultEQ
Make sure that the measurements are done in the best way as possible.
Choose a audiophile music with a sophisticated instrumentation. The lead vocals of the track should stay at the center position of the sound stage. Because MultEQ makes the adjustments that the first microphone position is similar with center of the sound stage. Before you begin the demonstration switch MultEQ off. Hear a few seconds and then switch MultEQ on. Now you will hear a ´much improved sound stage, a perfekt tonal balance and it sounds very sophisticated.
It is sometimes helpful to tell the customer what he hears. Then he feels much safer and its easier to judge the system.
If you have a different level between MultEQ ON and OFF. The reason is the strategy of MultEQ.
Don´t be shy to demonstrate Mult EQ with factory speakers and the headunit amplifier. The result will be a vast improvement just as well.

29. Troubleshooting You have no sound
check the DIP Switches of the headunit
You have a bad perfomance; the tweeters are very loud
check the microphone positions
You have no navigation voice
Have you a connection from the Headunit to the „Guide In“ on the PXA (KCE- 030N)?
Problems with the Software
You should have the latest software version V2.10
The software doesn´t detect the PXA
Make sure that you have installed the USB driver. Don´t use a USB cable with poor Quality.
