Beomaster 1100 in 1977/78 was a powerful, sensitive and compact unit incorporating an FM tuner and stereo amplifier.
The tuner had facilities for presetting four favourite stations, and once these had been permanently tuned, the programme of your choice could be instantly selected just by pressing a button. There was also a large slider and scale for manual tuning. An AFC (Automatic Frequency Control) switch was provided to help capture weak stations and keep them correctly tuned.
The amplifier section had a power output of 2 x 22 watts RMS with minimal distortion – less than 0,3% at full power. There were connections for two pairs of loudspeakers, a record player, headphones and a tape or cassette recorder (for which A monitoring facilities were also included).
Beomaster 1100 could be made up as part of the Beosystem 1100, together with other compatible Bang & Olufsen products.
