What is Surround Sound?
Date : 29/01/2009
Roll over any component to explore a surround sound setup.
Sound adds weight and presence to our visual experience. From the creak of approaching footsteps to the rumbling of a spaceship, surround sound makes movie images feel more real.
Equipping your home theater with at least five speakers and a subwoofer is what transforms a big TV into an incredible home theater.
Sound all around
In today’s entertainment productions, many microphones are used to record sound. In your home theater, these sound channels can be routed to different speakers to create a sense of depth and motion. When sound can move all around the room, you can really get swept up in the action.
How many speakers?
Audio quality designations of 5.1 or 7.1 — the highest sound-quality standard used today — tell you the number of channels available in a recording, and that corresponds to the number of speakers you need to most accurately reproduce the sound. The numbers 5 and 7 are the sound channels, and the .1 is the subwoofer.
To make your home theater great, go for five speakers, plus a subwoofer and place them properly around the room as shown in the illustration above. If you want to go high-end, try seven speakers. Some people have stuffed their home theaters with up to 11 speakers. Now that’s going all out with sound!
