“Sound is 50% of the movie experience” Steven Spielberg
Dolby THX
Home Cinema Surround sound is generated from the audio signal output from your source (DVD, SkyHD, Blu-ray). This is then processed by a dedicated amplifier (or receiver) and split into discrete signals that are sent to individual speakers positioned correctly in your listening environment to encircle the listener providing a realistic 360° of listening.
In order to achieve a true home cinema surround environment the speakers and amplifier ideally should be Dolby THX certified as this is the standard used by movie production houses when recording and authorising sound tracks for film.
According to the Dolby THX standard there are specific locations for speakers and also settings on the amplifier that have to be adjusted to replicate the sound track from a film accurately.
Home Cinema Surround sound comes in various flavours starting 2.1 and going up to 10.2. With the 1st number referring to the number of speakers channels and the second number referring the number of sub woofers (which deliver the bass signals).
The most commonly used standard is 5.1, which means 5 home cinema surround speakers and 1 subwoofer are used. Now most high quality audio visual receivers and amplifiers now come with 7.1 surround channels as standard.
