Creating a Surround Field in the Main Room
The
•You can use
The following operations are only possible while the receiver is ready for the main room operations, and are only used for the main room sources.
Surround modes
With this receiver, you can use two types of the Surround mode.
Following modes cannot be used when only the front speakers are connected to this receiver (without the rear speakers or center speaker).
Dolby Surround (Dolby Digital and Dolby Pro Logic) *
Used to watch the soundtracks of software encoded with Dolby
Digital (bearing the mark 
) or with Dolby Surround
(bearing the mark 
).
Dolby Surround encoding format records the left front channel, right front channel, center channel, and rear channel (total 4 channels) signals into 2 channels. The Dolby Pro Logic decoder built in this receiver decode these 2 channel signals into original 4 channel signals —
On the other hand, Dolby Digital encoding method (so called a discrete 5.1 channel digital audio format) records and compresses the left front channel, right front channel, center channel, left rear channel, right rear channel, and LFE channel (total 6 channels, but LFE channel is counted as 0.1 channel, therefore called 5.1 channels) signals digitally. Each channel is completely independent from other channel signals to avoid interference, therefore, you can obtain much better sound quality with much stereo and surround effects.
The Dolby Digital decoder built in this receiver can create much more realistic sound field in your listening room. You may feel as if you were in a real theater.
In addition, Dolby Digital enables stereo rear sounds, and sets the cutoff frequency of the rear treble at 20 kHz, comparing to 7 kHz for Dolby Pro Logic. These facts enhance the sound movement and
•To enjoy the software encoded with Dolby Digital, you must connect the source component using the digital terminal on the rear of this receiver. (See page 10.)
DTS Digital Surround **
DTS Digital Surround (bearing the mark 
) is another discrete
5.1channel digital audio format available on CD, LD, and DVD software.
Comparing to Dolby Digital, audio compression rate is relatively low. This fact allows DTS Digital Surround format to add breadth and depth to the reproduced sounds. As a result, DTS Digital Surround features natural, solid and clear sound.
• To enjoy the software encoded with DTS Digital Surround, you must connect the source component using the digital terminal on the rear of this receiver. (See page 10.)
DSP modes
With this receiver, you can use four types of the DSP mode.
DAP modes
In order to reproduce a more acoustic sound field in your listening room while playing music sources, you can use DAP modes. This mode can be used when the front speakers are connected to this receiver (without respect to the rear/center speaker connection).
THEATER 1: Reproduces the sound field of a large theater (where the seating capacity about 1,000).
THEATER 2: Reproduces the sound field of a small theater (where the seating capacity about 300).
HALL 1: Gives clear vocal and the feeling of a large concert hall (where the seating capacity about 1,000).
HALL 2: Gives clear vocal and the feeling of a small concert hall (where the seating capacity about 300).
LIVE CLUB: Gives the feeling of a live music club with a low ceiling.
DANCE CLUB: Gives a throbbing bass beat.
PAVILION: Gives the spacious feeling of a pavilion with a high ceiling.
5 CH/4 CH Stereo mode
You can create more powerful sound field for both of the digital and analog stereo sounds source. The 4 CH Stereo mode reproduces a sound filed through the front left and right speakers and rear left and right speakers. The 5 CH Stereo mode adds the center channel element to the 4 CH Stereo sound field by outputting mixed left and right signals through the center speaker. This mode cannot be used
when only the front speakers are connected to this receiver without the rear speakers.
Note:
“5CH STEREO” is selected when setting the center speaker to “LARGE” or “SMALL.” “4CH STEREO” is selected when setting the center speaker to “NONE” (see page 29).
