Surround modes
With this receiver, you can use three 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 Doby 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

DTS Digital Surround**
DTS Digital Surround is another discrete 5.1 channel 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 have more data recorded than Dolby Digital even using the same media, and 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 8.)
