1. PRECAUTIONS
1. The DVH920 can easily be damaged by mois-
ture, high temperatures or high humidity. Keep
the inside of the car clean and well ventilated.
2. Never subject the DVH920 to strong shocks
or open its case. Doing so may result in dam-
age.
3. Use a soft, dry cloth to wipe dirt off the
DVH920. Never use a hard cloth or thinner,
alcohol, etc. For tough dirt, apply some cold
or lukewarm water to a soft cloth and wipe off
the dirt gently.
4. When the main unit is switched to the traffic
announcement or PTY interrupt reception
while using the DVH920, the effect from
DVH920 doesn’t work.
5. Some tracks may sound distored when ad-
justment; this is normal and not a cause for
concern.

■ Onboard DTS/Dolby Digital/Pro Logic II Decoder
• Independent playback of DVD video surround format DTS, Dolby Digital 5.1ch.
• Utilizes Pro Logic II with advanced digital matrix technology for 5.1 channel decoding of 2-chan-
nel CD and radio.
■ Newly developed 32-bit DSP LSI with advanced processing performance
• DSF function allows application of 6 sound field effect patterns following decoding of DTS, Dolby
Digital 5.1ch format, or Dolby Pro Logic II signals.
• The parametric equalizer function allows you to adjust the frequency characteristics to suit the
car.
■ High precision 96 kHz / 24 bit D/A converter used in all channels
■ New-type digital input connectors
• New digital input connectors support sampling rate of 96 kHz.
32 kHz: MP3 etc.
44.1 kHz: CD, CD-R, CD-RW, MD
48 kHz: DVD video
96 kHz: DVD video
■ Supports analog input connectors (RCA 2ch)
(when optional control unit is connected)
• When center unit or other RCA 2ch output is connected to analog input connectors, Dolby Pro
Logic II function can convert to 5.1ch output.
■ Thin-line chassis can be installed beneath seat.
■ DTS
• DTS is an abbreviation for Digital Theater System; while this system possesses the same 5.1ch
format as Dolby Digital, its higher quantity of recorded data results in higher quality sound.

■ Dolby Pro Logic II
• Using the newest in digital matrix technology, Dolby Pro Logic II is a matrix decoder technology
which further improves earlier Dolby Pro Logic. This new technology produces superb 5.1ch
sound even with CDs and other stereo sources.
The surround channel is converted to full-band (20 Hz-20 kHz) stereo, thus allowing stereo
sources to be enjoyed with the impact of 5.1ch sound. Four modes can be set in accordance with
the playback source, including MUSIC mode, MATRIX mode, MOVIE mode, and VIRTUAL mode.
• Dolby Digital is a totally discrete digital 5.1 channel format. Signals for the front 3 channels, 2
surround channels, and the low-frequency 0.1 channel are recorded discretely, so no crosstalk
occurs between channels, and the sense of placement and depth of the sounds is reproduced
faithfully.

■ Digital Inputs (When Optical Digital Cable is Connected)
• When optical digital cable is used to connect components like a DVD changer, the digital signals
are given precedence in processing.
• When Dolby Digital (other than 2ch), DTS, Linear PCM (96 kHz) or other digital signals are input,
the Dolby Pro Logic II mode can be selected, but the mode will not perform ordinary audio pro-
cessing.
• When MP3 (32 kHz) and Linear PCM (96 kHz) digital signals are input, the Parametric Equalizer
(P.EQ) function can be operated, but it will not perform audio processing.

■ Speaker System
• To get maximum enjoyment from the
sound-field functions of this component,
the use of a 5.1ch speaker system is rec-
ommended. To demonstrate optimum
audio response, modify the adjust
mode’s default settings for “SP-SEL,”
“FILTER,” “SP-GAIN,” and “DELAY” in
accordance with the composition of your
speaker system (see P.10-11).

Setting Acoustic Features (DXZ925)
●PANORAMA (Y or N):
Selecting PANORAMA mode will extend the
front sound field image to the rear. If sur-
round effect does not seem to be presented
sufficiently, select the setting position [Y].
•The initial setting is [N].
●DIMENSION (0 to 6):
Selecting DIMENSION mode will shift the
sound field image to the front or the rear. If
the balance of the sound field image is too
much pulled towards the front or rear, the
balance front/rear can be corrected.
The adjusting value 3 is the center position.
The range of 3 to 0 shifts the balance front/
rear to the front. The range of 3 to 6 shifts
the balance front/rear to the rear.
•The initial value is [3].
●CTR WIDTH (0 to 7):
Selecting CTR WIDTH mode will adjust the
localization of the center channel between
the center speaker and the front speaker L/
R.
Distributing the center channel sound to the
right and left will increase the integrated
sound field image, providing you with an
natural spatial feeling of sound.
Setting to the value 0 will produce the cen-
ter sound with the center speaker.
Setting to the value 7 will distribute the cen-
ter sound to the front speaker L/R as the
existing stereo sound does.

How to Wire This Unit
CAUTION
Throughout the process of wiring this unit,
disconnect the negative (–) terminal of your
automobile’s battery, and leave it discon-
nected until completely finished. Handling
wires while the terminal is connected could
result in dangerous electrical shock or injury
if an accidental short circuit should occur.
Perform the settings and
connections in the order
indicated by the drawing
below.
CeNET connector
CeNET cable
Sliding cap
Optical Digital cable
(black connection)
Cable clip
1 CeNET Cable
•To connect a CeNET cable, hold it with the
connector facing as shown, and insert se-
curely.
•When disconnecting a CeNET cable, grasp
the slide cap and squeeze gently.
2 Optical Digital Cable (sold separately)
•Insert the black connector securely into the
digital signal input connector until it locks.
The cable clip can be used to secure up to
two optical digital cables.
•When disconnecting a optical digital cable,
squeeze the tabs at the right and left sides
of the connector, and pull gently.
Note:
•The optical digital cable should not be bent
with a gentle arc radius of 1.5 cm or less. If it
is bent sharper than this, the performance of
the cable will be greatly reduced and the cable
may be damaged.
3 RCA Pin Cable (sold separately)
•When connecting an RCA pin cable, be sure
to confirm the source of the connection first.
4 [RESET] switch
•Following completion of wiring, press the
[RESET] switch to return to default settings.
Note:
•Always turn the main [POWER] switch [OFF]
before connecting or disconnecting digital fiber-
optic cables.
Note:
•Route the CeNET cable with plenty of extra
room so that the connector will not become
disconnected accidentally.

■ Dolby Pro Logic II
•Faisant appel aux technologies les plus récentes du son matriciel numérique, le Dolby Pro Logic
II possède une technologie qui améliore les résultats du Dolby Pro Logic antérieur. Cette nouvelle
technologie restitue des sons 5.1 canaux superbes àpartir de CD et d’autres sources stéréo.
Le canal surround est converti en stéréo toute gamme (20 Hz - 20 kHz), ce qui permet de profiter
des sources stéréo avec l’impact de sons 5.1 canaux. Quatre modes sont disponibles en fonction
de la source de lecture, àsavoir le mode MUSIC, le mode MATRIX, le mode MOVIE et le mode
VIRTUAL.
•Le Dolby Digital est un format 5.1 canaux numériques totalement distincts. Les signaux des 3
canaux avant, des 2 canaux surround et du 0,1 canal basse fréquence sont enregistrés de façon
distincte et aucune diaphonie ne se produit donc entre eux, tandis que le sentiment de placement
et de profondeur des sons est restituéavec fidélité.
