3-EN
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 ball-point pen or
other such instrument, then insert the disc again.
Center Hole

Correct Handling
Do not drop the disc while handling. Hold the disc so you will
not leave fingerprints on the surface. Do not affix tape, paper, or
gummed labels to the disc. Do not write on the disc.
CORRECT
INCORRECT
CORRECT
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
diameter of the disc. Using such accessories can cause the disc to
be out of standard specifications and may create operational
problems. We recommend not using these accessories on discs
played in Alpine CD players.

Basic Operation
About the Crossover
Crossover:
This unit is equipped with an Active Crossover. The
crossover limits the frequencies delivered to the outputs.
Each channel is controlled independently. Thus, each
speaker pair can be driven by the frequencies for which
they have been optimally designed.
The crossover adjusts the HPF (high pass filter) or LPF
(low pass filter) of each band, and also the slope (how fast
the filter rolls off the highs or lows).

• HPF (high pass filter): Cuts the lower frequencies and allows the higher frequencies to pass.
• LPF (low pass filter): Cuts the higher frequencies and allows the lower frequencies to pass.
• Slope: The level change (in dB) for a frequency change of one octave.
• The higher the slope value, the steeper the slope becomes.
• Adjust the slope to FLAT to bypass the HP or LP filters.
• Do not use a tweeter without the HPF on or set to a low frequency, as it may cause damage to the speaker due to the low frequency
content.
• You cannot adjust the crossover frequency higher than the HPF or lower than the LPF.

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-7998/CDA-7897 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.
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 12.
10-EN
Here we calculate the time correction value for the front left
FL FR
RL RR
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").
Bass Focus
The time difference between the front-rear/left-right
speakers, can be adjusted at the same time. With an
initial delay of 0.1 ms for each of the 0 to 99 steps,
audible time correction can be done.
1 Press the T.CORR button to select the Bass Focus
mode.
→ Bass Focus mode → Time correction mode
Normal mode ←
2 Press the BAND button to select the front-rear / left-
right speakers.
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.

5 After setting, press and hold the T.CORR button for
least 3 seconds to return to the normal mode.
NOTES
• Any manual time correction adjustments will also affect
corrections made in Bass Focus.
• Bass Focus mode is automatically canceled if no buttons are
pressed within 15 seconds.

(2) After entering corrections for the left (front and rear)

for the front left speaker in STEP 1, the additional
correction in STEP 15 makes the time difference of the
front left speaker 3.0 ms.

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 .

CD (MX 1 to 3):
CD mode processes a large quantity of data. MX uses
this massive data quantity to enhance the sound
cleanly.
MP3/XM (MX 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 (MX1 to 3):
MX 1 to 2 (MOVIE): reproduces the dialog of movies
more clearly.
MX 3 (MUSIC): reproduces discs containing incidental
music, music clips, etc. more clearly and effectively.
AUX (MX 1 to 3):
Choose the MX mode (MP3, MUSIC, or MOVIE) that
corresponds to the media connected.

• 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, as the source changes
from “MP3 to CD-DA” or “CD-DA to MP3”, the MX-mode
needs to switch. This switching process may increase the time
before a piece is actually heard.
• Setting to MX OFF makes MX mode of each music source
OFF.
• This function is inoperable when DEFEAT is ON.
• MX mode does not function when MX is ON for AM radio.
