AVAILABLE SURROUND MODE 

The surround modes create a “live” atmosphere such as that 
experienced in movie theaters, discos, stadiums and concert halls. 

Select the appropriate surround mode according to the program 

source. (Note: Surround speakers are needed for DTS/DOLBY 

DIGITAL Dolby Pro Logic II surround modes to function). 
It is recommended to use a Center speaker when operating this 

unit in DTS/DOLBY DIGITAL/Dolby Pro Logic II surround modes. 

The  

DOLBY DIGITAL button can be pressed when you are using either 
an Optical or Coaxial cable as the input connection because these 

cables transmit the required encoded digital data.

The DOLBY PRO LOGIC and DTS buttons can be pressed when

This unit is provided with the following Surround modes allowing 

you to enjoy 5.1 (or 6) discrete channels of high quality digital 
audio from DTS program sources bearing the DTS trademark such 

as discs, DVDs and compact discs, etc. DTS Digital Surround 

delivers up to 6 channels of transparent audio (which means 

identical to the original masters) and results in exceptional clarity 
within a genuine 360 degree sound field. The term DTS is a 

trademark of DTS Technology, LLC. Manufactured under license 

from DTS Technology,, LLC. (Note: DTS program sources should 

be played back in DTS mode). 
 

 

                 

 

 

The Dolby Digital surround format lets you enjoy up to 5.1 channels 

of digital surround sound from a Dolby Digital program source. If 
you connect a DVD player or an LD player equipped with a DOLBY 

DIGITAL output to the DIGITAL (Dolby Digital)/DTS/PCM DIGITAL 

IN jack (Optical or Coaxial digital IN) on your AV Receiver and play 

DVD or laser discs with the Dolby Digital trademark, you will 
experience exceptional sound quality, great spatial accuracy, and 

improved dynamic range. This is because Dolby Digital delivers 5 

totally discrete, full frequency audio channels (Front Left Right, 

Center, Surround Left and Right), plus a "0.1" channel called LFE 
(Low frequency-only effects channel). 

Dolby Digital is a system developed by Dolby laboratories that 

transmits 5.1 digital signals, The surround system developed for 

movie theaters using this system is called “Dolby SR-D (Surround 
Digital)”. Because each channel is completely independent, a 

realistic sound field with a “three-dimensions” feel is achieved 

which gives the sound a sense of distance, movement and relative 

position, creating a real and powerful sense of presence. Some 
Dolby Digital programs carry information that allow you to 

compress the dynamic range of sound track, without degrading the 

sound quality, for softer sound effects when watching movies late 

at night.
