Installing the SACD multi-channel
audio speakers

In order to enjoy SACD multi-channel sound with the best pos-
sible acoustics, it is recommended that the speaker systems be
laid out in compliance with the ITU-R BS.775-1 recommenda-
tion which is a standard formulated by the International Tele-
communication 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 basi-
cally 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 recorded
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 an
example. The Sub-woofer can be located any place in
your room. (See the users manual of your sub-woofer.)
