Before Using This Product
About This Product
This product is universal digital preamp/equalizer which can be operated with the combined head unit DEX-P90RS (sold separately). You can operate a number of Audio Adjustment functions with separately sold head unit.
About This Manual
This product features a number of sophisticated functions ensuring superior reception and operation. All are designed for the easiest possible use, but many are not self-explanatory. This operation manual is intended to help you benefit fully from their potential and to maximize your listening enjoyment.
We recommend that you familiarize yourself with the functions and their operation by reading through the manual before you begin using this product. It is especially important that you read and observe the “Precaution” on page 8 and in other sections.
This manual mainly explains the remote control operation. In some functions, you can perform the same operations with the head unit, however, the remote control offers a number of buttons such as SHIFT, MENU, RETURN and FUNCTION buttons 1–6 which are not provided on the head unit. And all of audio adjustment operations can only be conducted with the remote control.
About the Digital Network
A vehicle, unlike the home audio, imposes several constraints upon the quality of reproduced sound, and have the following effects:
•Reflected sounds have strong effects on direct sounds because of the confined space and complex shape within a vehicle. This disturbs frequency characteristics and significantly reduces sound quality.
•The orientation of the sound image becomes unnatural, because speakers may not be installed symmetrically to left and right of the listener, or because speakers are installed in both the front and rear.
This system is equipped with a wide variety of functions that use DSP to create the ideal sound quality and sound image in a vehicle and overcome these constraints on reverberation.

Audio Adjustment
Audio Menu
This system has the following three Audio Menus:
Main <Main> (page 11)
This carries out Fader/Balance Adjustments as well as Bass/Treble Adjustment, the basis for sound quality adjustments. It also sets up and adjusts the Position Selector, which corrects the orientation of the sound image for the listener’s position in the vehicle.
Equalizer <Equalizer> (page 18)
This corrects complex frequency disturbance in a vehicle.
The Equalizer function for the component can make fine adjustments of sound quality for each frequency.
Network <Network> (page 23)
This adjusts the reproduced frequency band (cross-over frequency) and the level of each sound range (band) when a multi-amp system is set up. It also corrects unnatural orientation of the sound image caused by the locations of the speakers (using the Time Alignment function), by setting up a delay (time difference) between speakers set up for different sound ranges.
Note:
•The 5/∞/2/3 buttons on the head unit (DEX-P90RS) can not be used for Audio Adjustment operations.

Adjusting the Listening Position <PS> (Open state)
One way to assure a more natural sound is to clearly position the stereo sound image (putting you in the center of the sound field).
The Position Selector function adjusts distance and volume level of sound from each speaker to match seat positions and the number of people in the car, and lets you recall settings at the touch of a button. The result is a natural sound regardless of the seat you are sitting in.

Using the Position Selector <POSI>
1.Open the cover of the remote control in the Main Menu (refer to page 4).
This switches to Main Menu Setting Screen.
2.Press the FUNCTION button 2.
The display switches to Position Selector Screen.
3.Press the FUNCTION button 2 again to turn the Position Selector function ON.
4.Press one of buttons 2/3/5 and select the desired position.
Set up the position to match the position of the listener in the car.
Experimenting with other positions
•The position is normally designed to match the listener’s position in the car. However, other positions may prove to be more effective, depending on the model of the car and the location of the speakers. Compare the sound and choose the position in which the sounds are most natural.
13
Fine Tuning the Position
After choosing the position using the Position Selector function, it is possible to fine tune the distance and the difference in sound levels. Conduct the fine tuning to match the location of the left and right speakers and the shape of the car and correct the position of the sound image so that the sounds are most natural.
Distance (DIS): 0 — 340 cm (1.7 cm/1 step)
The longer the distance, the longer the sounds coming from the speaker take to reach the ears of the listener, giving the listener the feeling that the speaker is moving
further away. The sound image thus moves in the direction in which the value for the distance is closer to 0.
Adjustment range in the difference in sound levels (LEV): 0 — –30 dB (1dB/1step)
The smaller the level, the lower the sound volume output from the speaker, giving the listener the feeling that the speaker is moving further away. The sound image thus moves in the direction in which the value for the difference in sound levels is closer to 0.
Relationship between the distance and the delay time
It is necessary to adjust the delay time, irrespective of the distance between the listening position and each speaker unit, for better sound quality.
With this system, when you adjust the distance, the corresponding delay time is conducted automatically. It means that you can adjust the time alignment without calculating.
Note:
•Fine tuning can be conducted separately for each position.
•The values set after fine tuning are stored into memory as the values for the position. When the position is next called up, the fine tuning values are recalled.
1.Use the Position Selector function and select the position (refer to page 13).
Example: When selecting FRONT–L
2.Press the FUNCTION button 2 for two seconds and switch to Position Fine Tuning Screen.
3.Press FUNCTION buttons 1 or 2 and select the distance (DIS) adjustment or difference in sound levels (LEV) adjustment.
Continued overleaf.

4.Press the 2/3 buttons to correct the position of the sound image.
Holding down these buttons continues their operations (during distance tuning, holding down the button moves the distance 3.4 cm/1 step).
5.After tuning has been completed, press the RETURN button to cancel the Position Fine Tuning Screen.
The values are stored in memory and the display returns to Position Selector Screen.
Points concerning fine tuning
•While listening to vocals, adjust the distance to position the vocal sound image naturally to the front.
15
Effective distance Adjustment Using the Position Fine Tuning function
— Relation to Time Alignment Adjustment function —
When the system comprises a multi-amp system, the distance between the listening position and each speaker can be tuned using either of two methods.
Time Alignment Adjustment function of the Network Menu (page 25)
The distance between the listening position and each speaker of each band (high, mid, low and subwoofer) can be adjusted for the left and right speakers.
Distance tuning of the Position Fine Tuning function
The distance between the listening position and the left and right speakers can be tuned, regardless of the band. The same tuning is conducted for high, mid and low range bands. With a multi-amp system, combine the two methods to ensure the position of the sound images are set up more effectively.
1.Adjust the distance from each speaker using the Time Alignment Adjustment function of the Network Menu (refer to page 25).
2.Adjust the overall distance from the left and right speakers using the Position Fine Tuning Function.
Use the set values for the Time Alignment Adjustment function to fine tune the overall balance of the sound image positions.
3.Use the Position Fine Tuning Function to adjust the overall level balance between the left and right speakers.
Adjust the difference in sound levels between the left and right speakers so that the sound image is in the front.
Adjusting distance using the Position Fine Tuning function
•When the display has switched to Time Alignment Adjustment Screen after adjusting the distance between the listening position and each speaker using the Position Fine Tuning function, the values set using the Position Fine Tuning function will be added to the values created using the Time Alignment Adjustment function and the sum of the values displayed.
•To store the displayed values in memory as new values for the Time Alignment Adjustment function (standard values for the Position Fine Tuning function), adjust any one value again, using the 5/∞ buttons. The displayed values will be stored in memory and the distance between the listening position and each speaker set using the Position Fine Tuning function will be reset and returned to 0.
When the distance has been using the Time Alignment Adjustment function
•The distance adjustment of the Position Fine Tuning function uses the distance adjustment of the Time Alignment Adjustment function as its basis. If the distance is reset using the Time Alignment Adjustment function, this standard value is changed. When this happens, any distance adjustment previously set using the Position Fine Tuning function is reset to 0.

Source Level Adjustment <SLA> (Open state)
The SLA (Source Level Adjustment) function prevents radical leaps in volume level when switching between sources. Settings are based on the FM volume level, which remains unchanged.
1.Compare the FM volume with the volume of the other source (refer to DEX-P90RS (sold separately) Owner’s Manual).
2.Press the MENU button to switch to the Main Menu.
3.Open the cover of the remote control switches to Main Menu Setting Screen.
4.Press Function button 3 on MAIN Menu Setting Screen.
The display switches to SLA Adjustment Screen.
5.Increase or decrease the level with the 5/∞ buttons.
The display shows “+4” – “–4”.
Note:
•Since the FM volume is the control, SLA is not possible in the FM modes.
•The MW/LW volume level, which is different from the FM base setting volume level, can also be adjusted similar to sources other than tuner.
•The head unit’s CD player, Multi-CD player and DVD player are set to the same volume adjustment setting automatically.
•AUX, External 1 and External 2 are set to the same volume adjustment setting automatically.
