SURROUND SOUND CONFIGURATIONS
5.1 Channels
5.1 channel sound is 5 channels of audio stream
and 1 for the LFE (Low Frequency Effects). The setup would be 3 front speakers 1
right one centre and one left. There would then be 2 surround speakers. one left
and 1 right. The .1 represents the subwoofer which is best placed out of the way
under the desk etc to produce the best effects. The good thing about LFE and the
subwoofer is that it creates a feeling that the sound is everywhere despite
where you put the actually speaker.
6.1 Channels
With the 5.1 sound system there was 5 channels and
a LFE channel. With 6.1 however there isn't a 6th audio stream. The 6th
satellite speaker is utilised by combining the effects from the left and
right channel and mixing them to produce a rear speaker. The 6.1 system is the
first system to introduce a rear speaker. You will still have the 2 surround
speakers on either side of your seated position but now you can be immersed in
the sound, even if there are no more original sounds to be heard.
To make use of this Dolby created a new sound system called Dolby Digital
Surround -EX. This system first used in cinema's and now on DVD's allows users
with this special speaker setup to utilize the rear speaker by using a matrix
system to mix the left and right surround channels. This means that Dolby
Digital-EX is still considered to be a 5.1 channel system because it is not
"true 6.1 audio" however it does feel like it, that's good enough for most
people.
7.1 Channels
Dolby Digital Surround-EX system comes into play
when you have the 7.1 setup. This yet again adds another surround speaker to
your system. This time you have your basic 3 front speakers (left, right and
centre) but this time you have left surround, right surround, left rear surround
and right rear surround. This means that because you don't have a central rear
speaker the Dolby track and your sound hardware will have to decide how to
position this sound. The matrix system again comes into play to position your
rear sounds where they need to be played. This is done again by mixing the
original 2 surround channels so its still a 5.1 system but its enhanced and
again it feels much better.
