3-6. Mono
 
 
a. Academy Filter
 
Early movies had a mono soundtrack that suffered from 
audible hiss and a poor high-frequency response due to 
the quality of the film. To improve matters, the high-fre-
quencies were boosted before being recorded onto film, 
and then attenuated to their original levels during play-
back in the movie theater. Some old movies have been 
transferred to newer distribution media without the high-
frequencies being attenuated, creating a harsh sound 
with pronounced hiss. With the Academy Filter function, 
which is based on the playback techniques used in those 
days, you can attenuate the high-frequencies to their 
original levels and enjoy the movie as it was intended to 
be heard.
 
On:
 
 Academy Filter on.
 
Off:
 
 Academy Filter off (default).
 
 
b. Input Channel
 
With this setting you can specify how 2-channel sources 
are handled in the Mono listening mode.
 
AUTO L+R:
 
 The front left and right speakers output 
the same mix of the left and right channels 
(default).
 
Left:
 
The front left and right speakers output the 
sound recorded in the left channel. Use 
this option with material that has different 
languages recorded in the left and right 
channels.
 
Right:
 
The front left and right speakers output the 
sound recorded in the right channel. Use 
this option with material that has different 
languages recorded in the left and right 
channels.
 
3-7. Theater-Dimensional
 
These settings are used with the Theater-Dimensional 
listening mode.
 
 
a. Listening Angle
 
With this setting you can specify the angle of the front 
left and right speakers relative to the listening position. 
Processing for the Theater-Dimensional listening mode 
is based on this setting. Ideally, the front left and right 
speakers should be equidistant from the listening posi-
tion and at an angle close to one of the two available set-
tings.
 
20º:
 
Select if listening angle is 20 degrees.
 
40º:
 
Select if listening angle is 40 degrees (default).
 
 
b. Center
 
With this setting you can specify whether or not you’re 
using a center speaker. If you are, the center channel 
sound will be output by the center speaker when using 
the Theater-Dimensional listening mode. This reduces 
the workload of the front left and right speakers, and cre-
ates a more articulate sound space. In this case, the set-
tings for the distance between the listening position and 
each individual speaker (see page 43), and the level of 
each speaker (see page 44) are important, so be sure to 
set them.
 
On:
 
 Select if using a center speaker.
 
Off:
 
 Select if not using a center speaker (default).
 
 
c. Front Expander
 
With the Front Expander function you can broaden the 
width the front stereo image. This can be useful with nar-
row listening angles of 20 degrees or less.
 
On:
 
 Front Expander function on.
 
Off:
 
 Front Expander function off (default).
 
 
d. Virtual Surr Level
 
With this setting you can adjust the level of the virtual 
surround sound from –3 dB to +3 dB (default is 0 dB). If 
the clarity is poor, or the effect sounds unnatural, you 
may be able to improve it by lowering this setting.
 
 
e. Dialog Enhance
 
With this function you can improve the clarity of the cen-
ter channel, which usually contains dialog.
 
On:
 
Dialog Enhance function on.
 
Off:
 
Dialog Enhance function off (default).
 
3-8. Surround
 
These settings are for the surround sound modes.
 
 
a. Surr Mode (Analog/PCM)
 
This setting determines the default surround format to be 
used with analog and PCM input signals. The available 
options are: Pro Logic II Movie (default), Pro Logic II 
Music, Neo:6 Cinema, and Neo:6 Music.
 
 
b. Surr Mode (D.F. 2ch)
 
This setting determines the default surround format that 
will be used with 2-channel digital signals other than 
PCM. The available options are: Pro Logic II Movie 
(default), Pro Logic II Music, Neo:6 Cinema, and Neo:6 
Music.

This is the same as “Dolby Digital/Dolby Digital EX” on 
page 60. It can be set even while a listening mode other 
than Dolby is selected.
 
 
d. DTS-ES
 
This is the same as “DTS/DTS-ES Discrete/DTS-ES 
Matrix” on page 60. It can be set even while a listening 
mode other than DTS is selected.
