$325.00


Classic vintage 1970s tuner and FMreceiver with unique \"slide rule\" controls with handsome black anodized aluminum facia and rear grill in a beautiful rosewood case. Note: Picture shown are not the actual unit.I\'ve owned this unit since the 70s and will guarantee your satisfaction.
Built-in ambiophonic stereo switching for front and rear speakers. Rated at 60 watts per channel in terms of output, it\'s very powerful.Inputs for a record player and two tape recorders, one allowing A\\B monitoring. Headphone connection is on the receiver\'s front. The FM section has six pre-set stations. Lighted indicator assists accurate tuning with an illuminated meter indicated the strength of a station.
Field effect transistors, ceramic filters and integrated circuits are used throughout.
To quote from the Beoworld site:The amplifier section of this receiver had outstanding technical data: harmonic distortion was less than 0.1% at maximum power output and 0.06% at 50 mW. Frequency range was 20-30.000 Hz and effective bandwidth 10-35.000 Hz.
Ambio is sensed as being more spatial and acoustically more life-like than conventional stereo. The sound picture has greater depth because you get the added feeling of being present of the concert hall, listening to the actual performance. Ambio is based on the principle that in the concert hall you not only receive sound impressions directly from the performing group, you also get reflections from the wall and ceiling. The spatial sensation is instrumental in providing the auditory experience and even a two-speaker stereo system will not bring it out fully. And you cannot accomplish the effect by connecting additional speakers to a conventional stereo amplifier because you still have the same left and right front signals merely distributed to more speakers.In the Beomaster 4000 the left and right channels are subtracted from each other electronically and the resulting difference signal contains a certain amount of spatial information which is fed to the two new side speakers.
