The next essential element of the home theater experience is sound. This is implemented with either an AV receiver or preamplifier/amplifier combination. Your customer has a range of options to choose from in this area, from a basic all-in-one system, to a more sophisticated component system, all the way to a top-of-the-line high-performance system.
To fully enjoy HDTV and its Dolby Digital surround sound, recommend a home theater audio system or components with these key features at minimum:
The audio system should be at least a 5.1-channel surround sound system, which means at least a five-channel amplifier and a subwoofer output.
Speakers and Setup
Your customers will need at least six speakers - left, center, right, left surround, right surround and subwoofer - properly placed.
