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

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.
