Biotracer. The World's Most Advanced Tonearm
The tonearm problem - every tonearm functions to hold the cartridge, enabling the cartridge to trance the record groove. While this task is simple to describe, doing the job well is anything but simple. To prevent sonic coloration, the tonearm must be strong, a requirement that suggests heavy-duty construction. Yet some cartridges require low tonearm mass. At some frequencies the tonearm must be inert and immune to vibration - while at others it must move without resistance. And the tonearm must handle the imperfections of real-world records; warp and inaccurate centering.
All of the traditional methods of coping with these problems have dealt in pure mechanics. Sony has now taken a bold step beyond mechanics to find a solution to the troubles that have puzzled designers since the first turntables were presented to the world.
The Biotracer solution
Conventional tonearms are passive objects moved only as a result of external force. In contrast, Sony's new Biotracer tonearm is radically different. The Biotracer moves under the constant control of two separate motors that are guided by a "brain" - a sophisticated multi-function micro-computer. As a result the Biotracer tonearm is an active contributor to exquisite performance. In fact, it is the solution to a number of problems that have plagued turntable designers and music lovers.
The Biotracer damps resonance
It is an unfortunate fact that many cartridge/tonearm combinations produce unwanted resonances which distort the music. The Biotracer tonearm damps these unwatnted resonances consistently. Music reproduction is crystal clear and undistorted.
The Biotracer accepts the widest variety of cartridges
The problem of resonance limits even the finest conventional tonearms to a relatively small number of compatible cartridges. The Biotracer's ability to damp the unwanted vibrations of tonearm resonance means that you are free to choose from the widest variety of cartridges - moving magnet or moving coil - including the latest high-compliance models.
The Biotracer reduce modulation noise
In conventional tonearms, unwanted stylus motion results in modulation noise - a blurring of proper musical pitches. The Biotracer tonearm dramatically reduces such noise, for clear, crisp sound.
The Biotracer provides added precision
As music lovers are awere, the anti-skating and tracking force systems of conventional tonearms cannot be completely accurate. This is because record warps and eccentricities tend to alter the effective forces. You get mistracking and premature record wear. The Biotracer tonearm senses and immediately corrects for such external influences, automatically. You get perfect tracking. As an added benefit, you can even vary the tracking force while the record is playing, for the clearest possible sound.
The Biotracer tonearm does more than incorporate the latest in magnetic, microprocessing and electro-mechanical technology, it ends the long-standing compromises embodied in conventional tonearms, its precise operation, response to command and its extraordinary contribution to musical sound represent a significant advance in the state of the art..
