Home Theater Audio - What's Multichannel Surround Sound?
"Hi-Fi" and stereo were the large things for audio enthusiasts decades ago. Some individuals even bought vinyl records of sound clips just to marvel at the fidelity and stereo effects. Quadraphonic sound was tried for a time, but systems were expensive and recording and media required 2 additional channels. Within the last decade digital audio makes even more sophisticated systems not only possible but also affordable.
Multichannel surround sound, Dolby, and THX
Stereo uses 2 recorded sound channels to secure a left speaker plus a right speaker, roughly corresponding to our left and right ears. Multichannel audio processes additional channels to enhance the audio experience with additional speakers. There's several kinds of surround sound. The first runs on the fixed listener place for a 3-dimensional audio effect. Unfortunately this also means there's a single "sweet spot" where the effect works best. Other types use speakers behind the listeners to have an audience-wide experience. Each speaker feed is termed a channel.
Audio processing from Dolby Laboratories began in the past in the 1960s with noise reduction. Dolby processing has evolved to multi-channel surround-sound processing by way of a succession of small steps. Probably the most recent is Dolby TruHD. This allows loss-less encoding (no information lost, no noise added) of 8 or even more channels.
You may have find out about receivers boasting about THX. THX isn't actually a recording, encoding, or multichannel surround sound technology. It's actually a quality standard and certification system. Originally employed for movie theaters, it "guarantees" high-quality multi-channel sound.
5.1 Channel Systems
The most common arrangement today uses 6 speakers, and it is referred to as 5.1 channels. The ".1" channel is for a sub-woofer dedicated to powerful suprisingly low frequencies. A good sub-woofer is very important for movie and video game special effects. Two of the residual speakers are the standard stereo speakers. Another pair is also stereo, but these "rear" speakers they fit behind the listeners. So that you literally are encompassed by sound. The final speaker can be a middle speaker, placed between the front stereo pair. Ideally, it's mounted fairly high to supply a broad sound experience.
7.2 Channel Systems
Add 3 more speakers plus you've got a 7.2 channel system. Many current receivers can only handle 5.1, so make sure you choose one that can handle the 9 speakers if you want to go with this arrangement.
The ".2" speakers are two sub-woofers, making your deep bass truly stereo. The residual pair can be used in a number of ways. The best sound comes from placing them in front above the main stereo pair. Here you'd place the middle speaker a bit lower. You can also put them further to the left and right from the main stereo speakers. Finally, they are utilized as remote speakers in a entirely different room.
All in all
These may sound like complicated systems, but each channel and speaker has its purpose and place. They're not really that difficult to set up. You may have to be clever in running wires towards the rear speakers to ensure that they're not too visible, but wireless speakers are available if this is a lot of trouble. Either way, it's worth the effort. Installing a property theater surround sound system will raise your music listening, movie watching, as well as video gaming to a whole new level.
