1975–1977: Dolby goes cinematic
Dolby Stereo brought a breakthrough four-channel optical format to 35mm film, delivering Left, Centre, Right, and Surround channels from a standard soundtrack. It quietly launched in 1975, but it was the debut of Star Wars in 1977 that made the world take notice. For many, this was the moment that put Dolby on the map—when cinemagoers felt, possibly for the first time, that sound could be just as thrilling as the dazzling visuals on screen.
1982–1985: Surround comes home
In 1982, Dolby Surround translated theatrical experiences to VHS and LaserDisc. Denon launched its first Dolby Surround AV receiver, the AVC-300, in 1985—bringing directional sound to living rooms everywhere. For home audiences, sound made the leap from background to prominent storytelling element.
1987–1988: Dialogue takes the spotlight
Dolby Pro Logic further refined home theatre sound with its ability to decode a two-channel stereo signal into four separate channels. For film lovers, it was a game changer: Suddenly, whispers were clear as day, and action scenes had weight and direction. As Dolby brought cinematic balance to the home, Denon quickly integrated the format into our AV receivers, helping listeners hear every word and feel every moment.
