Bang & Olufsen Beocenter 7700

Details

The Beocenter 7700, launched in 1982, revolutionized music listening by providing perfect sound throughout the home. At that time, it was the only option available for enjoying music from the attic to the basement.

The Beolink® System and Integration with Beocenter 7700

Central to this innovation was the Beolink® system, which allowed users to control their music systems in multiple rooms. Just as great oak trees grow from small acorns, this product paved the way for today’s versatile TV and hi-fi systems. Consequently, these systems now synchronize for whole-house music using the latest MasterLink technology.

New Possibilities for Music Lovers

Moreover, this integrated system opened up new possibilities for serious music enthusiasts. For the first time, round-the-house hi-fi became a practical option, enabling high-quality sound in any room.

Features of the Integrated System with Beocenter 7700

Additionally, it featured Long, Medium, and FM radio, along with an automatic record deck and a microcomputer-controlled cassette recorder. Furthermore, the powerful 2 x 40 watts RMS stereo amplifier included two user-programmable 24-hour timers. Thus, you could easily access all sound sources using an infrared remote control.

Expanding Your Audio Experience

From this solid foundation, it was possible to expand your sound system either immediately or room by room. This setup allowed you to enjoy music from anywhere in the house. Ultimately, it set the stage for the future of integrated home audio, leading to the advanced Beolink® technology we know today.
