Speaker positioning for Super Audio
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). Super Audio 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
