Beocenter 3300 combined a powerful AM/FM stereo receiver with an automatic record player. Technically identical to the Beomaster 2200, the receiver section offered programmes on FM, long and medium wavebands and up to 2 x 40 watts RMS amplification with low distortion levels. It also had the same logical operation facilities.

The record player had a spring-suspended rotatory mechanism and an electronic servo drive system which ensured accurate turntable speed - even during variations in the mains current supplies. A special pendulum leaf spring suspension made the arm and platter immune to external shock and vibration which causes most other record players to mistrack and damage the record and sometimes even the stylus.
