4. Connections s Installing the SACD multi-channel audio speakers In order to enjoy SACD 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). SACD 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. q On SACD 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. q 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. q The location of the sub-woofer in the picture is just an example. The Sub-woofer can be located any place in your room.
