Bring movie quality sound into your home theater.
How it works
Dolby Digital surround sound is an advanced form of digital audio coding that makes it possible to store and transmit high-quality digital sound efficiently. It gives listeners and viewers a more realistic feeling.
Dolby Digital 5.1 surround sound is an audio coding technique capable of delivering sound with five discrete full-range channels — left, center and right surround — plus a sixth channel for those powerful low-frequency effects that are felt more than heard in movie theaters. This is commonly known as the subwoofer. The subwoofer needs only about one-tenth the space of the others and is referred to as a ".1" channel. Therefore, the entire group of channels is named Dolby Digital 5.1 surround sound.
Dolby Pro Logic features four channels: front left, center, front right, and a mono surround channel that is usually split between two rear speakers.
