Owner's Manual

28
The surround sound of the AV Receiver enables you to enjoy the
presence of a movie theater or concert hall in your room.
Before using any surround mode, make sure the Speaker Setup
configurations have been set (see page 18).
The speaker configuration is very important for the surround
sound. See “Positioning speakers/Connecting speakers” on pages
12 – 13. For operational instructions, refer to the page 29.
Following are the sound systems the AV Receiver can reproduce.
Dolby Digital surround, DTS (Digital Theater
System) surround
This 5.1-channel digital surround format enables you to individually
record and play five full-range (20 Hz-20 kHz) 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 could be heard in the theaters and concert halls.
Dolby Digital
Select this option when you play a DVD video that has a mark.
DTS
Select this option when you play a DVD player, LD, or CD that has
a
mark.
•
If you press the pause or skip button on the player while playing a
DTS source, a short noise may be heard. This is not a malfunction.
• The DTS indicator on the HT-R420 lights up while it plays the DTS
source. When playback concludes and the DTS signal transmission
stops, the HT-R420 remains in DTS mode and the DTS indicator
remains lit. This prevents noise when you operate the pause or skip
button on the player. Therefore, if the source switches from the
DTS signal to the PCM signal immediately, the PCM signal may
not be played. In this case, stop the playback of the source on the
player for about 3 seconds, then resume playback.
• Some CD players and LD players may be unable to play DTS
sources correctly even if you connect the player to the
HT-R420 digitally. This is because the digital signal has been
processed (such as the output level, sampling frequency,
frequency response, etc.), and the HT-R420 cannot recognize
the signal as DTS data. Therefore, you may hear noise when
you play a DTS source while processing the signal.
• The TAPE OUT or VIDEO 1 OUT jacks of the HT-R420
output analog audio. Do not record CDs or LDs that support
DTS using these jacks. Otherwise, you will record a DTS
encoded signal as noise.
Dolby Pro Logic II (Movie/Music)
This mode is a new generation 5-channel surround system that provides
performance between the 4-channel (left front, right front, center, and
monaural surround) Pro Logic Surround and the 5.1-channel Dolby
Digital Surround. This mode can be set to the Movie mode designed for
playing movies and the Music mode designed for listening to music.
In the Movie mode, the surround channels, which used to provide
monaural output over only a narrow frequency range, now provide
complete stereo output over the full frequency range. The result is
viewing worth a realistic feel of movement.
Enjoying the listening modes
The Music mode uses the surround channels to provide a natural
sound space that cannot be provided with normal stereo output.
This mode can be used with VHS and DVD videos with the
mark and certain television programs. The Music mode
can be used with music compact discs and other stereo sources.
If no surround speakers are connected, then the surround sound is
divided and output from the front left and right channels.
Onkyo’s original Digital Signal Processing
(DSP) modes
Analog sources include audio records, AM/FM broadcasting and
cassette tapes. The PCM (Pulse Code Modulation) signal is a kind
of digital audio signal, which is recorded directly on CD or DVD
without being compressed. When an analog or PCM source is
played, you can enjoy unique surround modes to Onkyo as listed
below.
Orchestra
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 simulates a natural reverberation as created in a
large hall.
Unplugged
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.
Studio-Mix
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.
TV Logic
This mode offers the realistic acoustics of a TV program being
aired in the TV studio. It enhances the entire surround sound and
clarity of conversation.
All Ch St (All Channel Stereo)
This mode is useful for background music. The front and surround
channels will create a stereo image.
Stereo mode, Direct mode
Stereo
This mode has all input sound is output from the left and right front
speakers. Subwoofer also can be used for playback.
Direct
This mode delivers pure sound with minimum sound quality
adjustment and filtration. The sound recorded for the left and right
front channel is output to the left and right front speakers only and
not output to the subwoofer.
