Center Mode
Set the center mode as described below, according to the type of
center speaker being used.
Normal mode; This mode is suited for an arrangement in which
the center channel speaker is smaller than the left and right
speakers. Signals below 100 Hz which have almost no effect on
directional
orientation are distributed to the left and right
channels, whereas the center channel output signals greater than
100 Hz. As a result, the bass of the left and right channels
increases the apparent deepness of the sound.
Wide mode: This mode is suited for an arrangement in which the
center channel speaker is of the same grade as the left and right
speakers. The entire sound band from low region to high is output
to the center channel to provide an exciting sound field for your
enjoyment.
Phantom mode; Use this mode when center channel speaker is
not used. A directional emphasis circuit provides signal reproduc­
tion which is electrically oriented to the center and this provides
an exciting sound field for your enjoyment.
De!ay Time
The optimum delay time will differ depending on the listening
position. Referring to the chart at right, set the optimum delay
time for your room's space and seating position. For example,
when the distance from the front speakers to the listening
position is 20 feet and that from the rear speakers to the listening
position is 15 feet, the optimum delay time will be 20 ms.
The variable range of the delay time differs depending on the
mode.
