A light touch to the front of the Beocord 6500 cassette recorder released the loader which glided out slowly and silently in order to allow you to insert a cassette. You could use whichever type of cassette you prefer; or choose between Dolby B or C Noise Reduction systems... and rejoice in Bang & Olufsen's patented HX-PRO recording system which ensured optimal sound reproduction, particularly in the difficult, high-frequency range. And, naturally, Beocord 6500 had auto-reverse so that both sides of the tape played as one.

Beocord 6500 could be used as part of the Beosystem 6500 hi-fi system.

Auto Record level

One of the less-pleasant chores in making a recording is setting level control to its optimum position. Setting it too low raises the level of background noise on the recording. Setting it too high makes the recording distorted at high music levels. With this in mind, Bang and Olufsen introduced an automatic record mode which was called 'Auto Record'.

Auto Record worked in two steps: when the record button was pressed for the first time, the cassette recorder went into a record pause mode, where the incoming signal was monitored. Under microprocessor control, the highest level was monitored and the record level was set at the optimum level for that music. On pressing the record button the second time, the tape was set in motion and the recording started, but continuing to make minor adjustments. If at any time during the recording, the level of music rose above the monitored level, the level control was lowered by exactly the amount required for the new optimum recording level.

This method of setting the level control closely imitated the action of a highly skilled recording engineer, if asked to set the level for a recording. It was the best that could be done when the full recording could not be monitored before recording started.

This feature incorporated a new method of monitoring the signal, which proved to be a more effective method over conventional methods. It was patented by the company with the patent number 158702.
