Learn the proper way to setup your audio cables and settings to enjoy Dolby Digital 5.1 sound. All of Shaw's digital cable channels (i.e. channels that require a Digital Terminal to be watched) have some form of Dolby Digital audio (audio that is digitally encoded) -- whether it be Dolby stereo, Dolby surround, Dolby Digital 5.1, etc. The Info screen or Quick Bar on the Shaw Interactive Programming Guide will indicate when a TV program is broadcasting Dolby Digital 5.1 sound.
 

This article will provide insight into:

 

What's required for Dolby Digital 5.1 audio

To take full advantage of the Dolby Digital 5.1 audio output from your Shaw Digital Box (whenever it is available on a TV program or movie title), the following items are required:
 

  1. A Shaw Digital Box with S/PDIF or HDMI outputs (please note: all Shaw Digital Boxes offer Dolby Digital 5.1 capabilities with the exception of the following models: Motorola DCT700 and DCT2000)
  2. An S/PDIF or HDMI cable to connect between your Digital Box and receiver
  3. An Audio Receiver capable of delivering Dolby Digital 5.1 sound (five speakers plus sub-woofer)
  4. TV program or movie title needs to have been filmed and broadcast in Dolby Digital 5.1
  5. Configure Guide Audio Settings on your Digital Box (press Settings/Menu twice, then navigate to Setup>Audio Setup) according to the following:
    • Audio Output: Advanced
    • Compression: None
    • Stereo Output: Matrix

 

Your television's speaker or stereo sound will still work with HDTV but will not produce Dolby Digital 5.1 sound. If you are unsure of whether your Digital Box is capable of delivering Dolby Digital 5.1 audio to your sound system, locate your model here: Shaw Digital Boxes - Equipment Guide and check whether the audio outputs for your model include at least one of the following: S/PDIF (coaxial or optical), or HDMI.

The table below outlines the maximum audio capability of cables in use between a Digital Box and a TV or audio receiver. Please note: coaxial and HDMI cables are able to carry both picture and audio; RCA, S/PDIF optical and coaxial carry audio only.

How to set up your speakers

Dolby Digital 5.1 sound is encoded with six discrete audio channels, each going to a separate speaker.  To enjoy Dolby Digital 5.1 sound to the fullest, you will need all six speakers for each respective channel.
 

  • Satellite speakers (left, right, center and two rear) can be compact since they are not required to produce low bass
  • The speakers should have the same timbre or tonal characteristics
  • Front speakers should be off the ground and facing out
  • Center speaker should be directly on top or under the TV
  • Space the rear speakers widely apart but facing each other at just above typical ear's listening height
  • The sub-woofer is for the sounds felt more than heard, need not be in view and can be hidden
