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.

Disc Cleaning

Fingerprints, dust, or soil on the surface of the disc could cause
the CD player to skip. For routine cleaning, wipe the playing
surface with a clean, soft cloth from the centre of the disc to the
outer edge. If the surface is heavily soiled, dampen a clean, soft
cloth in a solution of mild neutral detergent before cleaning the
disc.

Disc Accessories

There are various accessories available on the market for
protecting the disc surface and improving sound quality.
However, most of them will influence the thickness and/or

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/CDA­7892 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.

Rotary encoder

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)

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.

8-EN

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.

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 Press the T.CORR button to select the Bass Focus

mode.

(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.

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.

Tips

* Subwoofer speaker.
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 .

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.

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.
