MULTI-CHANNEL
SOUND
In
order
to
enjoy Super Audio CD multi-channel sound with
the best possible acoustics, it is recommended to position
speakers as specified
in
ITU-R BS.775-1 of the International
Telecommunication Union (ITU). SuperAudio
CD
multi-channel
discs are recorded and mixed so as to achieve the optimum
effect with a speaker system laid out as specified
in
ITU-R
BS.775-1.
With Super Audio CD multi-channel discs, the music signals
are basically recorded using 5 channels
(3
- 6 channels
sometimes), but
in
some cases, LFE (for subwoofer)
is
recorded as a sixth channel. Each disc indicates how many
channels have been recorded on
it.
The basic layout
is
3 speakers
in
the front and 2
in
the back
since multi-channel discs usually have 5 channels. The 2
front, 1 center and 2 surround (rear) speakers should be set
in
a circle around the listening point as shown below.
If
using
speakers of differing sizes, adjust volume balance from the
amplifier.
The location of the subwoofer
in
the figure is just for
explanatory purposes. It can be located anywhere
in
the
room. For connection and positioning instructions, see the
instruction manual that came with the subwoofer.
