Installing the SACD multi-channel audio speakers
CONNECTIONS
In order to enjoy SACD multi-channel sound with the best
possible acoustics, it is recommended that the speaker
systems be laid out in compliance with the ITU-R BS.775-1
recommendation which is a standard formulated by the
International 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
recommendation.
• On SACD multi-channel discs, the music signals are
basically 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 in your amplifier/surround receiver.
• 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.)
