WARNING

PRECAUTIONS

Never Attempt the Following

Do not grip or pull out the disc while it is being pulled back into the player by the automatic reloading mechanism.

Do not attempt to insert a disc into the unit when the unit power is off.

Inserting Discs

Your player accepts only one disc at a time for playback. Do not attempt to load more than one disc.

Make sure the label side is facing up when you insert the disc. Your player will automatically eject any disc that is inserted incorrectly. If the player continues to eject a correctly inserted disc, push the RESET switch with a pointed object such as a ballpoint pen.

Playing a disc while driving on a very bumpy road may result in skips, but this will not scratch the disc or damage the player.

New Discs

As a protective measure to prevent the CD from jamming, the CD player will automatically eject discs with irregular surfaces or inserted incorrectly. When a new disc is inserted into the player and ejected after initial loading, using your finger, feel around the inside of the centre hole and outside edge of the disc. If you feel any small bumps or irregularities, this could inhibit proper loading of the disc. To remove the bumps, rub the inside edge of the hole and outside edge of the disc with a ballpoint pen or other such instrument, then insert the disc again.

About the Time Correction

The distance between the listener and the speakers in a car vary widely due to the special conditions of the mobile environment. This difference in the distances from the speakers to the listener creates a shift in the sounds image and frequency characteristics. This is caused by the time delay between the sound reaching the listener’s right versus the left ear.

To correct this, the CDA-7995/CDA-7894/CDA-7893/CDA-

7892 is able to delay the audio signal to the speakers closest to the listener. This effectively creates a perception of increased distance for those speakers. The listener can be placed at an equal distance between the left and right speakers for optimum staging.

The adjustment will be made for each speaker in a step of

0.1 ms.

Example 1. Listening Position: Front Left Seat

Adjust the time correction level of the front left speaker to a high value and the rear right to zero or a low value.

 

5.1ms

0.5m

 

2.25m

 

 

 

Tips

*Subwoofer speaker.

You cannot change the Time Correction value for the subwoofer, but you can set the subwoofer's apparent position to the front by adjusting the Time Correction value of the front and rear speakers.

For details, refer to the "Tips" on page 9.

Here we calculate the time correction value for the front left speaker in the diagram at the left.

Conditions:

Farthest Speaker – listening position : 2.25 m (88-9/16") Front left speaker – listening position : 0.5 m (19-11/16")

Calculation: L = 2.25 m – 0.5 m = 1.75 m (68-7/8")

Time correction = 1.75 ÷ 343* × 1000 = 5.1 (ms) *Speed of sound: 343 m/s (765 mph) at 20˚C

In other words, giving the front left speaker a time correction value of 5.1 ms makes it seem as if the distance to the front left speaker is the same as the distance to the farthest speaker.

The sound is not balanced because the distance between the listening position and the various speakers is different.

The difference in distance between the front left speaker and the rear right speaker is 1.75 m (68-7/8").

Time correction eliminates the differences in the time required for the sound to reach the listening position.

The time of the front left speaker is corrected by 5.1 ms so that its sound reaches the listening position at the same time as the sound of other speakers.

Example 2. Listening Position: All Seats

Adjust the time correction level of each speaker to almost the same level.

1 Sit in the listening position (driver’s seat, etc.) and measure the distance (in meters) between your head and the various speakers.

2 Calculate the difference between the distance to the farthest speaker and the other speakers.

L = (distance to farthest speaker) – (distance to other speakers)

3 Divide the distances calculated for the speakers by the speed of sound (343 m/s (765 mph) at 20˚C).

These values are the time correction values for the different speakers.

Bass Focus

The time difference between the front-rear/left-right speakers, can be adjusted at the same time. With an initial delay of 0.3 ms for each of the 0 to 39 steps, audible time correction can be done. For finer adjustment, use the procedure in the previous section "Time Correction," for which the delay steps are 0.1 ms.

1 Press the T.CORR button to select the Bass Focus mode.

→ Bass Focus mode → Time correction mode

3 Turn the Rotary encoder to adjust the front-rear / leftright delay.

4 For setting another channel (speaker), repeat the steps

2 and 3.

5 After setting, press the T.CORR to return to the normal mode.

NOTES

Any manual time correction adjustments will also affect corrections made in Bass Focus. However, since the interval of the manual mode is 0.1ms and that of Bass Focus is 1 step (0.3ms), some difference may occur.

Time Correction mode is automatically canceled if no buttons are pressed within 15 seconds.

Example of Steps 2 and 3 Setting

(1)After entering corrections for the front (left and right) speakers in STEP 5, the time difference is 1.5 ms for both front-left and front-right speakers.

1.5ms

1.5ms

(2)After entering corrections for the left (front and rear) speakers in STEP 5, the time difference becomes 3.0 ms* for the front left speaker and 1.5 ms for the left rear speaker.

* Because the time difference was already set to 1.5 ms for the front left speaker in STEP 1, the additional correction in STEP 5 makes the time difference of the front left speaker 3.0 ms.

Delay (turn the rotary encoder) the audio signal to the front (left and right) speakers to make the apparent position of the subwoofer to be at the front. In doing this, the apparent position between the front (left and right) speakers and subwoofer will appear equal to the driver. After performing above, you can change the positions of left and right speakers by delaying the time .

Time Correction

Before performing the following procedures, refer to

"About the Time Correction" (page 8).

1 Make time corrections by pressing the T.CORR button.

Each press changes the modes as follows:

→ Bass Focus mode → Time correction mode Normal mode ←

2 Select a speaker to be adjusted by pressing the BAND button.

→ F – L → F – R → R – L → R – R

3 Adjust the desired time correction value by turning the

Rotary encoder.

4 For setting another speaker, repeat the step 2 and 3.

5 After setting, press the Rotary encoder to return to the normal mode.

NOTE

Time Correction mode is automatically canceled if no buttons are pressed within 15 seconds.

Setting the MX Mode

MX (Media Xpander) makes vocals or instruments sound distinct regardless of the music source. The radio, CD, and MP3, will be able to reproduce the music clearly even in cars with a lot of road noise.

1 Press the MX button to select MX ON.

2 Press the SOURCE button to select the source you want to MX (Media Xpander)-correct.

3 Press and hold the MX button for at least 2 seconds to select the MX mode.

4 Turn the Rotary encoder to select your preferred mode or OFF (NON EFECT).

FM (MX level 1 to 3):

The medium to high frequencies become more clear, and produces well balanced sound in all the bands. CD (MX level 1 to 3):

CD mode processes a large quantity of data. This data is used to reproduce the sound cleanly by making use of the data quantity.

MP3/XM (MX level 1 to 3):

This corrects information that was omitted at the time of compression. This reproduces a well-balanced sound close to the original.

DVD (Video CD) (MX level 1 to 2):

The dialog portion of the video is reproduced more clearly.

DVD (CD) (MX level 1):

This disk contains a large quantity of data such as music clip. MX uses this data to reproduce the sound accurately.

AUX (MX level 1):

Choose the MX mode (MP3, MUSIC, or MOVIE) that corresponds to the media connected.

5 After setting, press the Rotary encoder to return to the normal mode.

NOTES

By “Setting the Defeat of the external input” (page 16) to ON, operation is bypassed.

To cancel MX mode for all music sources, press the MX button to turn MX off.

MX mode is automatically canceled if no buttons are pressed within 15 seconds.

Each music source, such as radio, CD, and MP3 can have its own MX setting.

On disks with both MP3 and CD-DA, when the source changes from “MP3 to CD-DA” or “CD-DA to MP3”, the MX-mode switching process may take a little time before a piece is played due to.

Setting to MX OFF makes MX mode of each music source OFF.

This function is inoperable when DEFEAT is ON.
