Placement of speakers
As well as enjoying normal stereo reproduction with both the left
and right front speakers connected, a center speaker and rear
speakers can also be connected to the main unit in order to enjoy
playback with a feeling of presence using the Dolby Pro-Logic
Systems.
The illustration below shows where to place the speakers when
enjoying sound with Dolby Pro-Logic systems.
The listening position at which the effect is the greatest is a posi-
tion slightly to the rear of a center position of five-speaker
systems.
However the position should be adjusted to your personal
preference, because the effect varies to some degree depending
upon the type of music and the music source.
