remote to start Disc playback, press DISC first.
You cannot activate some features, such as Angles, Subtitles, or multi-language Audio.
• The feature may not be available on the Disc. Check the Disc case to see if the Disc has the feature. If the Disc does not have
the feature, the DVD Receiver cannot create the feature. This is not a malfunction of the DVD Receiver.

DVD Receiver again as usual.
There is no sound from the Center or Rear/Surround speakers.
• Press CENTER +/- or REAR+/- on the remote control to adjust the volume level.
• Make sure the Center and Rear/Surround speakers are connected correctly. Details are on page 14.
• Choose a correct Surround Sound setting. Surround Sound must be available on the current Disc or broadcast. Details are on
page 35.
Radio broadcasts are noisy or have considerable static.
• Tune to the correct frequency. Details are on page 37.
• Connect the antennas. Details are on page 10.
• Route Cable TV/RF/AC-3 and digital cables away from the antennas and speaker wires.
• Fully extend the FM wire antenna and position it for the best reception.
• Connect an outdoor FM or AM antenna.

Glossary

Analog: Sound that has not been turned into numbers.
Analog sound varies, while digital sound has specific numerical
values. Analog sound is available when you use the red and
white audio jacks on your equipment. These jacks send audio
through two channels, the left and right.
AUDIO OUT Jacks: Jacks on the back of the DVD
Receiver that send audio to another system (TV, Stereo, etc.).
Bit Rate: The amount of data used to hold a given length of
music; measured in kilobits per seconds, or kbps. Or, the
speed at which you record. Generally, the higher the bit rate,
or the higher the recording speed, the better the sound quali-
ty. However, higher bit rates use more space on a Disc.
For example, an MP3 music file recorded at 32 kbps will
record slowly, use the least Disc space, and have the poorest
sound quality. But, an MP3 music file recorded at 96 kbps will
record quicker, use more Disc space, and have significantly
better sound quality.
Coaxial jack: Sends digital audio to a Stereo, allowing you
to adjust the volume at the Stereo. The Stereo must have a
coaxial in jack. This connection provides the 5.1 channel sur-
round sound as heard in movie theaters.
Component Video Out Jacks: Jacks on the back of the
DVD Receiver that send high-quality video to a TV that has
Component Video In jacks.
Digital: Sound that has been converted into numerical val-
ues. Digital sound is available when you use the DIGITAL
AUDIO OUT COAXIAL or OPTICAL jacks. These jacks
send audio through multiple channels, instead of just two
channels as analog does.
Dolby Digital: A surround sound system that provides 5.1
channel sound as used in movie theaters.
DTS: Digital Theater Systems. This is a surround sound sys-
tem, but it is different from Dolby Digital. The formats were
developed by different companies.
DVD: Digital Video Disc.
Letterbox: A TV aspect ratio setting (4:3). Displays the
video in full-width, with black bars at the top and bottom of
the TV screen. This format is similar to seeing a movie in a
theater. If the Disc does not include a letterbox format ,
selecting Letterbox may have no effect. (For example, some
DVDs are two-sided, with one side playing in Letterbox and
the other side playing in a normal format.)
OPTICAL Jack: Converts electrical signals into optical sig-
nals before sending the audio to the Stereo. Optical audio is
not prone to external electrical influences and has less noise,
which reduces adverse effects on external equipment. Be sure
to keep the protective cap on the jack when the jack is not in
use. This keeps dust out of the jack.
Pan & Scan: A TV aspect ratio setting (4:3). Displays the
video with full-height picture, with one or both sides of the
picture trimmed. Some movie companies refer to this as
"reformatting the picture to fit your TV screen."
PR PB Y: See Component Video Out Jacks.
S-Video: Produces a clear picture by sending separate sig-
nals for the luminance and the color. You can use S-Video
only if your TV has an S-Video In jack.
VIDEO OUT Jack: Jack on the back of the DVD Receiver
that sends video to a TV.
Widescreen: A TV aspect ratio setting (16:9). Displays the
video appropriately when you connect the DVD Receiver to
a widescreen TV.
