Which Audio Connection Should I Use? 
If you are not using HDMI, which carries both the video and the audio signal, you have three options 
for connecting your Blu-ray DVD Player: Digital Coaxial, Digital Optical, or Analog. Based on your 
home theater configuration, you can decide which option is the right one for you.

Connector  Description 
Best 
(digital) 
 
Digital Coaxial (or coax) carries the digital audio signal using 
shielded copper wire and connects with RCA jacks, which stay 
firmly connected. Coaxial cables may be susceptible to 
interference so 'hum' problems in the system components. The 
cable carries all available audio channels—left/right stereo and 5.1-
channel surround sound. 
Best 
(digital) 
 
Digital Optical (also known as Toslink) carries the digital signal 
using a red light beam through plastic fiber optic cable. Optical 
cables are not susceptible to interference but are more fragile than 
coax cables and cannot be bent or pinched. The ends of an optical 
cable use an odd-shaped connector that is not as secure as a 
coaxial cable with RCA jacks. The cable carries all available audio 
channels—left/right stereo and 5.1-channel surround sound. 
Compatible 
(analog) 
 
Analog consists of two cables for transmitting audio: one red and 
one white. It is capable of transmitting stereo sound and while it 
provides good sound, it is lower quality than HDMI or one of the 
digital options. So try to use one of those connections first.
