n 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 multichannel 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
0
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
0
recorded on it.
The basic layout is 3 speakers in the front and 2 in the
0
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. If using speakers of differing sizes, adjust volume
balance from the amplifier.
The location of the subwoofer in the figure is just for
0
explanatory purposes. It can be located anywhere in
the room. For connection and positioning instructions,
see the instruction manual that came with the
subwoofer.
