Setting of the PXA-H100


1) Set Amplifier Gains:Front & Rear = 1/2 gain Subwoofer = 1/4 gain

Step 4 - Crossovers & Gains

2) Turn all Amplifier Crossovers ’OFF’• Allow the PXA-H100 to Set the correct

Crossovers for the best Sound Quality • NOTES:

• If subwoofer Low-Pass Crossover cannot be turned off then select the highest frequency setting (eg. 200Hz)

• If subwoofer Subsonic Filter cannot be turned off then select the lowest frequency setting (eg. 15Hz)

200Hz

15Hz


• Install IMPRINT Sound Manager Software• If necessary install the USB- drivers

• Requires:• PC with Windows XP • PXA-H100 Setup Disc V2.10• 2m USB to Mini USB cable

Step 5 - Software Install

*Notice: although Windows Vista has not been officially approved by Audyssey Labs, it will work in most cases. Please contact your local Alpine support for details.


When the microphone is connected with the PXA-H100 the HU will show the message “MultEQ Setting Mode Don´t touch any button”

• It’s now time to connect your PC via USB • Requires:

• PC with Windows XP (with any or no service pack)

• IMPRINT Sound Manager software installed• included USB to Mini USB cable

Step 6 - PC Setup


Step 7 - Preparing the Vehicle & Microphone

2) Attach the microphone to a camera tripod, using the pre-threaded nutsert

*Notice: Make sure the microphone is connected to the PXA-H100

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.


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...


Step 8.1 – Start the latest Program Version 2.10

• Connect the PXA-H100 to your Computer

• Start PC Programm

•Select PXA-H100


Step 8.2 - Listening area Selection

Select which area is your prefered listening position by double click. For example Front left.

That means the timedelay will be set for this position.


Step 8.3 - Measuring Position 1

*Notice: Microphone MUST be pointing straight up

2) Exit the Vehicle and Close ALL Windows and Doors.

1) 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.


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.


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


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.



2) Exit the Vehicle - Close ALL Windows and Doors

1) 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.

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




1) Move the Microphone to the co driver side Listening Position

*Notice: Place the microphone at normal ear height, centered approximately 5,0 cm in front of the headrest position.



Step 8.8 - Measuring Position 41) Move the Microphone to the front left corner

of the driver seat *Notice: Reduce the height of the Mic to shoulder height



*Notice: Reduce the height of the Mic to shoulder height


Step 8.9 - Measuring Positions 5 1) Move the Microphone towards to the center

console as far as possible while keeping it on the driverseat

*Notice: use the same height like position 4




Step 8.10 - Measuring Positions 6

1) Move the tripod with the microphone to the rear right position of the driver seat surface.

*Notice: use the same height like position 5




1) 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.

2) 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.

3) Double-click to select your preferred curve.

Step 8.11 - Finishing MultEQ


1) 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

Step 8.12 - Selecting a Target Curve

3) Double-click when you have finished


Step 8.13 – Save PermanentlyAfter 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.


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

If the Sub is not loud enough, you can adjust the Gain for the Sub amp

Step 10 - Fine Tuning

You can do some fine tuning BASS/MID/High on the headunit


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.


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.


TroubleshootingYou 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.
