Basic Playback HOME THX CINEMA modes THX is a set of technical standards created by Lucasfilm, Ltd. These standards were designed to emulate a film sound stage and thus reproduce, with the greatest possible accuracy, the soundtrack intended by the filmmakers. To get THX sound use one the three modes explained below. You will only be able to access the second two modes if you have hooked up SURROUND BACK speakers. For more detailed information see p.19,21,33-34.This mode is best if you are unsure which of the above THX modes to use. The display will show you what kind of source (Dolby Digital, DTS, etc.) is being played. THX CINEMA Use this mode to get THX sound with sources that do not have SURROUND BACK channels. If you don't have SURROUND BACK speaker(s) switched on (see p.33-34.) this is the only THX mode you will be able to select on the receiver. THX SURROUND EX This mode is specifically for using your SURROUND BACK channels with either SURROUND EX sources or 5.1 channel sources. You will only be able to access this mode if you have set the SURROUND BACK speaker(s) in the SPEAKER SETTING procedure (see p.33-34). If the source you are using is a 5.1 source then this mode will route some of the sound to the SURROUND BACK channel(s). If the source you are using does not have a SURROUND EX marker or is not a 5.1 source then the display will automatically change to THX CINEMA. THX AUTO In this mode the receiver will automatically select the appropriate THX mode and use it to play the soundtrack. You will only be able to access this mode if you have set the SURROUND BACK speaker(s) in the SPEAKER SETTING procedure (see p.33-34). If the source has a SURROUND EX marker then the receiver will automatically go into THX SURROUND EX mode. This mode is best if you are unsure which of the above THX modes to use. ADVANCED THEATER modes The Advanced Theater mode is a newly designed system for enhancing movie soundtracks and other audiovisual sources. It incorporates the use of DTS as well as Dolby Digital into its sound processing. These functions switch on automatically when the source you are playing is encoded with DTS or Dolby Digital. There are four Advanced Theater settings that use DSP (Digital Signal Processing) to create different types of sound environments. If you have SURROUND BACK speakers or (even just one) speaker switched on (see p.33-34) then 7.1 will appear after the name of all of these modes in the display on the receiver. The display will show you what kind of source (Dolby Digital, DTS, etc.) is being played. MUSICAL This mode is primarily for music and adds a spacious feeling to the sound. A long delay time of reflected sounds, provides resonant tones which emulate a concert hall. DRAMA This mode is designed for movies with a lot of dialog. The elements of dialog are enhanced, making the characters seem more real. The mode also compresses the dynamic range somewhat so loud sounds do not overpower softer ones (compare this with the MIDNIGHT LISTENING mode explained on p.49). ACTION This mode is designed for action movies, which generally use lots of sound effects. The mode enriches the sound to make it more realistic and extends the parameters to pick up high and low sound effects. 5/7-D THEATER This mode is especially designed to give sound depth to stereo sources. The overall effect builds a dynamic and broad sound space, allowing two-channel (stereo) signals to faithfully imitate a five speaker sound. The mode should be used in conjunction with Dolby Pro Logic for sources bearing the mark. DOLBY SURROUND memo When a Dolby Digital soundtrack is played back the Dialog Normalization function of the receiver activates automatically. Dialog Normalization is a Dolby Digital function that establishes the average dialog level for the program source being played. If the receiver's level does not match the average dialog level, first you see "DIAL NORM" flash in the receiver's display and next "OFFSET +4 dB" (as an example) will appear. In this example, the number +4 dB is the difference between the receiver's gain structure and the Dolby Digital average dialog level. To match the average dialog level, subtract or add the OFFSET level. For example, if the OFFSET level is +4 dB, the amplifier's output is 4 dB over the average recorded level. 42

memo
HOME THX CINEMA modes
THX is a set of technical standards created by Lucasfilm, Ltd. These standards were designed to emulate a film
sound stage and thus reproduce, with the greatest possible accuracy, the soundtrack intended by the filmmakers.
To get THX sound use one the three modes explained below. You will only be able to access the second two
modes if you have hooked up SURROUND BACK speakers. For more detailed information
see p.19,21,33-34.
This
mode is best if you are unsure which of the above THX modes to use. The display will show you what kind of
source (Dolby Digital, DTS, etc.) is being played.
THX CINEMA
Use this mode to get THX sound with sources that do not have SURROUND BACK channels. If you don't
have SURROUND BACK speaker(s) switched on (see p.
33-34.
) this is the only THX mode you will be able to
select on the receiver.
THX SURROUND EX
This mode is specifically for using your SURROUND BACK channels with either
SURROUND
EX sources or
5.1 channel sources. You will only be able to access this mode if you have set the SURROUND BACK
speaker(s) in the SPEAKER SETTING procedure (see p.33-34). If the source you are using is a 5.1 source
then this mode will route some of the sound to the SURROUND BACK channel(s). If the source you are
using does not have a
SURROUND EX marker or is not a 5.1 source then the display will automatically
change to THX CINEMA.
THX AUTO
In this mode the receiver will automatically select the appropriate THX mode and use it to play the
soundtrack. You will only be able to access this mode if you have set the SURROUND BACK speaker(s) in
the SPEAKER SETTING procedure (see p.33-34). If the source has a SURROUND EX marker then the
receiver will automatically go into THX SURROUND EX mode. This mode is best if you are unsure which of
the above THX modes to use.
ADVANCED THEATER modes
The Advanced Theater mode is a newly designed system for enhancing movie soundtracks and other audio-
visual sources. It incorporates the use of DTS as well as Dolby Digital into its sound processing. These functions
switch on automatically when the source you are playing is encoded with DTS or Dolby Digital. There are four
Advanced Theater settings that use DSP (Digital Signal Processing) to create different types of sound
environments. If you have SURROUND BACK speakers or (even just one) speaker switched on (see p.33-34)
then 7.1 will appear after the name of all of these modes in the display on the receiver.
The display will show
you what kind of source (Dolby Digital, DTS, etc.) is being played.
MUSICAL
This mode is primarily for music and adds a spacious feeling to the sound. A long delay time of reflected
sounds, provides resonant tones which emulate a concert hall.
DRAMA
This mode is designed for movies with a lot of dialog. The elements of dialog are enhanced, making the
characters seem more real. The mode also compresses the dynamic range somewhat so loud sounds do
not overpower softer ones (compare this with the MIDNIGHT LISTENING mode explained on p.49).
ACTION
This mode is designed for action movies, which generally use lots of sound effects. The mode enriches the
sound to make it more realistic and extends the parameters to pick up high and low sound effects.
5/7-D THEATER
This mode is
especially designed to give sound depth to stereo sources. The overall effect builds a
dynamic and broad sound space, allowing two-channel (stereo) signals to faithfully imitate a five speaker
sound. The mode should be used in conjunction with Dolby Pro Logic for sources bearing the
DOLBY SURROUND
mark.
When a Dolby Digital soundtrack is played back the Dialog Normalization function of the receiver acti-
vates automatically. Dialog Normalization is a Dolby Digital function that establishes the average dialog
level for the program source being played. If the receiver's level does not match the average dialog level,
first you see "DIAL NORM" flash in the receiver's display and next "OFFSET +4 dB" (as an example) will
appear. In this example, the number +4 dB is the difference between the receiver's gain structure and
the Dolby Digital average dialog level. To match the average dialog level, subtract or add the OFFSET
level. For example, if the OFFSET level is +4 dB, the amplifier's output is 4 dB over the average recorded
level.
