I Installing the SACD multi-channel
audio speakers
In order to enjoy SACD multi-channel sound with the best
possible acoustics, it is recommended that the speaker sys-
tems be laid out in compliance with the ITU-R BS.775-1 rec-
ommendation which is a standard formulated by the Interna-
tional Telecommunication Union (ITU).
SACD multi-channel discs are recorded and mixed in such a
way that they will achieve the optimum effects when the
speaker systems are laid out as per the ITU-R BS.775-1 rec-
ommendation.
G
On SACD multi-channel discs, the music signals are ba-
sically recorded using 5 channels (or 3, 4 or 6 channels
in some cases). In some instances, however, LFE (for
the sub woofer) is recorded as a sixth channel.
Each disc indicates how many channels have been re-
corded on it.
G The basic settings are 3 speakers for front and 2 for back
since multi-channel discs have basically 5 channels
The 2-front, 1-center, and 2-surround speakers should
be set on the circle from the listening point as shown
below.
When you use different sizes of speakers, please adjust
the volume balances.
