JVC DX-T9 Manuel D’Utilisation

 

–

 

 Uncompressed digital audio, the same 

format used for CDs and most studio masters. 

–

 

 Compressed digital audio, developed by 

Dolby Laboratories, which enables multi-channel 
encode to create realistic surround sound.

–

 

Compressed digital 

audio, developed by Digital Theater Systems, Inc., which 
enables multi-channel like Dolby Digital. As the 
compression ratio is lower than for Dolby Digital, it 
provides wider dynamic range and better separation.

• If you use a DVD-RAM with a cartridge, take the disc out 

of the cartridge before inserting.

 

• If you store a new station into an occupied preset number, 

the previously stored station in that number will be erased.

• When you unplug the AC power cord or if a power failure 

occurs, the preset stations will be erased in a few days. If 
this happens, preset the stations again.

 

• On some DVD, SVCD, or VCD discs, the actual operations 

may be different from what is explained in this manual, due 
to the programming and disc structure; such differences are 
not a malfunction of this System.

• When playing back a DVD Audio disc recorded in MLP 

(Meridian Lossless Packing; a lossless audio compression 
system that can completely recreate the PCM signal), the 
signals are recognized as the linear PCM signals, however, 
no indicator lights up on the display.

• This System can recognize up to 4 000 files in a disc. Also, 

the System can recognize up to 150 files per group and up 
to 99 groups in a disc.
– If there are any unplayable files in a folder, those files are 

also counted in the total file number.

– Playable files which do not belong to any groups are 

handled as Group 1.

• For MP3/WMA playback...

– MP3/WMA discs require a longer readout time than 

regular CDs. (It depends on the complexity of the group/
file configuration.)

– Some MP3/WMA files cannot be played back and will 

be skipped. This results from their recording processes 
and conditions.

– When making MP3/WMA discs, use ISO 9660 Level 1 

or Level 2 for the disc format.

– This System can play back MP3/WMA files with the 

extension code <.mp3> or <.wma> (regardless of the 
letter case—upper/lower).

– It is recommended that you make each MP3/WMA file at 

a sampling rate of 44.1 kHz and at bit rate of 128 kbps. 
This System cannot play back files made at bit rate of less 
than 64 kbps.

 

• The adjustment for the subwoofer level does not affect the 

sound through the headphones.

 

• When you unplug the AC power cord or if a power failure 

occurs, the User Mode settings will be erased in a few days. 
If this happens, set the User Modes again.

 

• Dolby Pro Logic II Modes: Dolby Pro Logic II Mode is a 

multichannel playback format to decode 2-channel sources 
into 5.1 channels. Dolby Pro Logic II reproduces spacious 
sound from original sound without adding any new sounds 
or tonal colorations.

• While you use the headphones, the Surround Mode is 

canceled temporarily (“STEREO” appears) and you cannot 
use SURROUND MODE and EFFECT.

• Some DVD Audio discs prohibit downmix. While playing 

back such a disc...
– You cannot change the Surround Mode. (“MULTI CH” 

appears on the display.)

– The System plays back the left front and right front 

signals when you have selected “STEREO” for the 
Surround Mode or when you use the headphones. (“LR 
ONLY” appears on the display.)

 

• You cannot change the scanning mode to progressive in the 

following cases:
– When your TV does not support the progressive video 

input.

– When you have not connected your TV to the unit using 

a component video cord.

 

•  “AM 12:00” will flash on the display until you set the 

clock.

• The clock may gain or lose 1 to 2 minutes per month. If this 

happens, reset the clock.
