INSTALLING THE SUPER AUDIO CD MULTI-CHANNEL AUDIO SPEAKERS

In order to enjoy Super Audio CD multi-channel sound with the best possible acoustics, it is recommended that the speaker systems be laid out in compliance with the ITU-R BS.775-1 recommendation which is a standard formulated by the International Telecommunication Union (ITU).

Super Audio CD multi-channel discs are recorded and mixed in such a way that they will achieve the optimum effects when the speaker systems are laid out as per the ITU-R BS.775-1 recommendation.

•On Super Audio CD multi-channel discs, the music signals are basically recorded using 5 channels (or 3, 4 or 6 channels in some cases). In some instances, however, LFE (for the sub woofer) is recorded as a sixth channel.

Each disc indicates how many channels have been recorded on it.

•The basic settings are 3 speakers for front and 2 for back since multi-channel discs have basically 5 channels The 2-front, 1-center, and 2-surround speakers should be set on the circle from the listening point as shown below. When you use different sizes of speakers, please adjust the volume balances.

•The location of the sub-woofer in the picture is just to you a patter of settings. Sub-woofer can be located any place in your room. (See the users manual of your sub-woofer.)
