Nº40 Media Console
Menu System
The Nº40 provides a variety of processing options for two channel
material. They include:
•
2-ch Stereo
Used to play the two-channel signal in its native state through
the front left and front right speakers. Note that if you have
specified a crossover and subwoofer, it will still be used in this
mode. (You can change this as another part of the sound
profile.)
•
Stereo Surround
Used with music to extract ambient information contained in a
recording, and to place that information out in the surround
speakers where it belongs. The front left and front right chan-
nels remain unprocessed, and a slight amount of center-fill
information is added to widen the effective listening area. This
is a relatively subtle effect that strives to be as natural as possi-
ble rather than have a striking effect.
•
Mono Center
The mono signal is formed by summing the left and right chan-
nels. The result is sent out the center speaker only.
•
Mono on Front Speakers
The mono signal is formed by summing the left and right chan-
nels. The result is sent out all three front speakers (L,C,R).
•
Mono Surround
The mono signal is formed by summing the left and right chan-
nels. This mode uses all available loudspeakers to add some
additional ambience to create a larger sound field.
•
Dolby Pro Logic
Used with specially encoded two channel recordings, correctly
called “Dolby Surround” recordings, but often called “Pro Logic
encoded” recordings. Although some Dolby Surround music
recordings exist, the large majority of Dolby Surround record-
ings are films created after 1976. (Note that most of these films
will sound better when reproduced with the addition of THX
post-processing.)
•
Dolby Pro Logic with THX
The same decoding as above, but with the addition of THX post
processing: re-equalization of the front channels, and decorrela-
tion and timbre-matching of the surrounds.
•
Dolby Pro Logic II Movie
Can be used with either music or movies (though again, most
movies benefit from THX as well); it even works well with mate-
