It started with Stereo…
A quick and informative history lesson:
- “Stereo” was created back in 1881 when Clément Ader demonstrated the first two-channel audio system at the Paris Electrical Exhibition.
- In the 1930s, Harvey Fletcher of Bell Laboratories investigated techniques for stereophonic recording and reproduction.
- But it wasn’t until 1958 that the first stereo records were issued by Audio Fidelity.
- In 1971, quadraphonic sound was introduced with four separate channels.
- Then in the ‘90s, surround sound was initially introduced in theaters, then ultimately, for home use.
7.1 Channel
Surround
Surround sound refers to the different audio channels "surrounding" the audience, whether it’s in a theatre or at home.
-
The most common system today is 7.1 Channel Surround.
Here’s how that breaks down:
- Two channels for speakers at the front - left (LF) and right (RF).
- One channel for a speaker at the center (C).
- Two channels for surround speakers at the sides - side left (L) and side right (R).
- Two channels for surround speakers at the rear - surround left (LS) and surround right (RS).
- One low-frequency effects channel (LFE).
Now the next challenge – where do you position these speakers for optimum response? That’s where RadioActive comes in – when we come to your home, we will look at your home and then discuss the solutions that are available. |
