The surround sound of the DVD Receiver enables you to enjoy the presence of a movie theater or concert hall in your room.
Before using any sound effect, make sure the Speaker Setup configurations have been set (see page 18).
The speaker configuration is very important for the surround sound. See "Connecting Speakers" on page 12 and "Positioning
Speakers" on page 13.
Following are the sound systems the DVD Receiver can reproduce.

This surround format consists of four channels (left and right
front, center, and monaural surround channel) and
emphasizes the center channel. This format is very effective
for panning music, conversation, and three-dimensional
sound movement output from three front channels. It also
simulates the atmosphere and surround effects of the sound
reflected from the side and rear walls of the theater. Select
this option when you play a VHS, VHS Hi-Fi, laser disc, or
DVD video that has the 

 mark.

The DVD Receiver offers the following special Onkyo sound
effects for sources other than Dolby Digital and DTS sounds.

This mode is suitable for classical and opera music. The
center channel is cut and the surround channels are
emphasized to widen the stereo image. It will simulate a
natural reverberation as created in a large hall.

This mode is suitable for acoustic instrumental sounds,
vocals, and jazz music. By emphasizing the front stereo
image, it simulates the acoustics in front of the stage.

This mode is suitable for rock and popular music. Lively
sounds with a powerful acoustic image will make you feel as
if you are in a club.

This mode offers a realistic acoustics of a TV program being
aired in the TV studio. It enhances the entire surround sound
and clarity of conversation.

This mode is useful for background music. The front and
surround channels will create a stereo image.

This 5.1-channel digital surround format enables you to
individually record and play five full-range (20Hz-20kHz)
channels (left and right front, center, two surround channels)
plus an LFE channel (Low Frequency Effect) for the low-
range effect sound. It will create a realistic sound that can be
heard in the theaters and concert halls.

Select this option when you play a DVD video that has the

 mark.

Select this option when you play a DVD video, laser disc, or
CD that has the 

 mark. To playback DTS Surround sound

with the connected equipment such as a video disc player,
the digital connection is a must in addition to the above
speaker configuration.

• If you play a DTS Surround encoded disc with the DVD Receiver,

or a DTS encoded disc using the digitally connected player, you
may hear a noise for a short while until the DTS decoder of the
DVD Receiver recognizes the DTS encoded signal and starts
operating. This is not a malfunction.

• If you pause, or skip a chapter or track, while playing a DTS

Surround source, a short noise may be heard. This is not a
malfunction.

• Even when playback of the DTS Surround source stops and the

DTS signal transmission ends, the DVD Receiver remains in DTS
mode and the DTS indicator remains lit. This is to prevent noise
when you pause, fast forward, fast reverse, or skip a chapter or
track of the playback source. Therefore, if the source switches from
the DTS signal to a PCM (2 channel digital stereo) signal
immediately, the PCM signal may not be played. In such a case,
stop playback for about three seconds, then resume playback.

• Some CD players (if connected to the DVD Receiver) and video

disc players may be unable to play DTS Surround sources
correctly even if you connect the player to the DVD Receiver
digitally. In such a case, the digital signals (such as the output
level, sampling frequency, frequency response, etc.) processed by
the player cannot be recognized as DTS data by the DVD Receiver
and you may hear noise instead of the proper sound.
