Dolby Pro Logic
II
Dolby Pro Logic II is a matrix decoding technol-
ogy in which the updated digital matrix technol-
ogy is applied and Dolby Pro Logic is further im-
proved. It realizes excellent 5.1 channel repro-
duction of Dolby surround source as well as ste-
reo sound sources such as CDs, thereby caus-
ing a surround channel to be full-ranged (20 Hz
to 20 kHz) and become stereo. Therefore, you
can enjoy any stereo sources with dynamic
sound of 5.1 channel. According to a source to
be reproduced, Music Mode or Matrix Mode can
be selected.

● Music Mode
This mode is suitable for stereo sources like
CDs. By optimizing frequency characteristics of
the surround channel, a broader and deeper
sound is assured. In addition, since broadness
of the sound field varies with recording condi-
tions of music sources, there is Adjusting Mode
which makes a finer tuning available. (cf. page
16)
● Matrix Mode
This mode is suitable for AM/FM radio.
