Operation 10
Unfortunately not all listening rooms are suitable for
exploiting the full dynamic range. For example, it may be
necessary to take your neighbours' feelings into account
- especially in the late evening hours.
For this reason it is possible to reduce the dynamic
range of Dolby digital encoded sound sources in such a
way that quiet passages (e.g. whispered conversations)
are reproduced somewhat louder, while loud passages
(e.g. gigantic explosions) are reduced in volume slightly
(see 'Main Menu').
dts Digital Surround
The 'dts' multi-channel film sound system was originally
developed to replace analogue film soundtracks, using
digital soundtracks consisting of six discrete channels.
This system has now been further developed to provide
spatial sound reproduction in the home situation.
The six channels (5.1) are encoded / decoded in original
quality, i.e. with 20-bit resolution, and recorded using
only slight data compression. The 5.1 loudspeaker con-
figuration, currently the standard arrangement for home
cinema systems, is ideal for playback.
STEREO / MONO mode:
Stereo
mode for stereo reproduction
Note
In this mode a multi-channel signal is converted into a
stereo signal (downmix), and reproduced via the main
left and right loudspeakers.
Mono mode for mono reproduction
All channels are mixed down onto the Cen-
ter loudspeaker *).
Mono I mode for two-channel TV sound
Generally Channel I transmits the synchro-
nised sound. The signal from Channel I is
reproduced via the Center loudspeaker *);
Channel II (original sound) is suppressed.
Mono II mode for two-channel TV sound
Generally Channel II transmits the original
sound. The signal from Channel II is repro-
duced via the Center loudspeaker *); Chan-
nel I (original sound) is suppressed.
Notes
*) If no Center speaker is present (see 'Loudspeaker
Menu'), the Center channel is mixed onto the left and
right main speakers.
Not all signal sources (DVDs, CDs etc.) which are en-
coded with Dolby Digital or DTS Digital Surround contain
the full 5.1 information. Even if the screen indicates that
a channel is present, that does not necessarily mean that
sound signals will constantly be produced from that loud-
speaker.
In every mode of reproduction signals can be made
available on the subwoofer channel, depending on the
loudspeakers selected in the 'Loudspeaker Menu'.
SOUND FIELD SIMULATION
The surround processes already described require pro-
gramme material which is encoded using the appropriate
system, but the K6 also offers a facility to enhance the
spatial effect available with conventional unencoded
stereo recordings (CD, MC, VHF radio etc.). This it does
by offering a range of artificial sound field simulations,
including theatre, stadium, club etc. These sound fields
are based on a precise analysis of the acoustics found in
typical concert halls.
The digital signal processor of your K6 is capable of
simulating the spatial sound of these halls, and repro-
ducing it via the five channels of your surround system.
For example, if you select the HALL setting while
watching a rock concert on television, you will have the
illusion of sitting in the middle of the audience.
Note
The sound field simulation is not available for true multi-
channel programs (DOLBY, dts)!
Your K6 can generate the following sound fields:
Disco
This sound field is particularly suitable for providing
an even spread of sound over a dance floor, using
the front and surround loudspeakers. The sound sig-
nal is mixed and passed to the front and surround
speakers without reflections and delays, and with
equal power. The strongly concentrated sound repro-
duction generates an immediate, energy-charged at-
mosphere which is a great choice for any party.
Hall
A resonant concert hall with reflections from all direc-
tions. Ideal for reproducing a large orchestra, or the
live atmosphere of a large rock concert hall - an ex-
cellent choice for highly dynamic rock music.
Theatre
This program combines the entire spectrum of clear
voice reproduction with the full sound reproduction of
an orchestra, without any unnatural echo. For better
orientation the room sound is restricted slightly to-
wards the rear.
Stadiun
Sound image with a narrow presence in the front re-
gion. Commentators and dialogues are localised on
the screen. The rear resonance provides the impres-
sion of the public in the stadium. This sound field is
also suitable for TV shows and music transmissions.
Club
The characteristic cellar jazz club atmosphere, with a
pattern of sound reflection which is dominated by
large floor and wall surfaces. Also good for simulating
small halls.
Church
Simulation of the acoustic conditions of a large
church with a long resonant period. This sound field
is the perfect choice for sacred organ music.
