DOLBY PRO LOGIC SURROUND
e Setting the delay 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 setting
position. For example, when the distance from the front
speakers to the listening position is 6 m and that from
the rear speakers to the listening position is 4 m, the
optimum delay time will be 21 ms.
The variable range of the delay time differs depending
on the mode.
For details about the variable range, see Page 12.

NORMAL mode
16
Normal mode: This mode is suited for an arrangement
in which the center channel speakers are 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 outputs signals greater than 100 Hz. Asa
result, the bass of the left and right channels increases
the apparent deepness of the sound.

PHANTOM mode
Phantom mode: Use this mode when center channel
speakers are not used. A directional emphasis circuit
provides signal reproduction which is electrically
oriented to the center and this provides an exciting
sound field for your enjoyment.

WIDE mode
Wide mode: This mode is suited for an arrangement in
which the center channel speakers are 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.
Test Tones
This function emits test signals for adjusting the levels of
the different channels for Dolby Pro Logic surround. When
the T.TONE button on the remote control unit is pressed,
test tones are emitted from the speakers, starting from the
front left speaker.
Before playing sources recorded in Dolby Pro Logic
surround, arrange the speakers as shown on the diagram
above, then use the test tones to adjust the balance
between the volumes of the speakers to achieve the most
appropriate balance for the listening position, and adjust
so that the level of the sound from all the speakers seems
to be the same.
To stop emitting the test tones, press the T. TONE button
once again. There are two test tone patterns, automatic
and manual, selected with the PARAMETER button.
In addition, enjoy other surround modes using the volume
balance adjusted in the Dolby Pro Logic mode as the basis.
For some playback sources the volume balance may not
be optimal, so readjust it to suit your tastes.
