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.

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.

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.

The location of the sub-woofer in the picture is just to you
a patter of settings. Sub-woofer can be located any place
in your room. (See the users manual of your sub-woofer.)
