n Speaker Positioning for Super Audio

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.

0

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.

0

Each disc indicates how many channels have been

recorded on it.

0

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. 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.

When the input source is POWER AMP, adjustment of the volume,

muting and balance has no effect. Adjust the volume on the pre-

amplifier.

When the input source is set to POWER AMP, you cannot use the

remote control unit to select the input source.

0

When the input source is POWER AMP, the main unit outputs at
