Dolby Pro Logic-Audio Systems
The Pro Logic system is a sound format which uses computer circuitry to route directional information to the appropriate speakers. There are two main speakers (attached to your audio system or kept near it) and two other speakers that are kept in different parts of the room. The sound is played normally through the two main speakers, and the computerized circuitry sends particular sounds through the other three speakers in the room. Dolby Pro Logic gives excellent 3-D effects to the sound.
