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
instruction manual that came with the subwoofer.
