Dolby Surround is a process that makes movies more exciting by creat- ing a more realistic audio experience to accompany the action on the screen. Rather than all the sound coming from the front of the theater (or your living room), the sound seems to surround you, making you feel like you are closer to the action.

The Pro Logic technology makes home theater sounds more realistic. The Pro Logic decoder separates the audio according to the apparent loca- tion of the source. You hear dialogue from the center speaker, normal ste- reo background sound from the left and right front speakers, and en- hanced surround sound from the rear speakers.

Dolby Surround Encoded Material

Program sources such as laser discs, video tapes, and cable broadcasts are usually direct copies of the original motion picture’s sound track. All these sources have surround sound audio if the original sound track had it. Many video tapes and laser discs are marked with the logo. However, many that are not marked also have surround sound au- dio.

In addition, many television stations broadcast regular programs with Dol- by Surround. Also, most satellite pro- grams, especially movies, are broadcast with Dolby Surround.

The System 745 gives you the best sound performance from music sourc- es that have the logo.

Selecting the Dolby Surround Mode

When playing a program source en- coded with Dolby Surround Sound, follow these steps to select the proper surround mode.
