What is stereo?

There are now two system of high fidelity, monophonic (monaural) and stereophonic. Monophonic is a system that starts from one microphone and is fed through a single high fidelity set. Stereophonic is a double system. Two separate microphones are placed at different sides of the orchestra and two different systems are used to keep the two signals or channels separated. Two separate speakersare used, placed on different sides of you room. Stereo is much like 3-D photography, two slightly different sound reach your ears giving you a new dimension in sound.

Thorens TD 145 (1975-1976), Mk II (1976-1978)

For years turntable manufactures have been seeking the faultless tonearm system that would eliminate stylus damage and protect records. Thorens with its long tradition of advanced engineering and state-of-the-art technology, has achieved this breakthrough in the new TD-145. Its completely unique and innovative electronic sensing system automatically lifts the tonearm and shuts off power to prewent any mishaps.

Totally electronic, rather than machanical, as are most automatic lift-up/shouoff systems, nothing inhibits the tonearm or comes between it and the trip mechanism. As the tonearm approaches the final lead-out grooves of the record, a control signal activates a viscous damped elevating platform that lifts the tonearm and shuts off th epower. Further, the sensing system goes into action instantly should the power be inadvertently cutoff or if the tonearm accidentally slides across the record. It's virtually foolproof.

The new sophisticated Thorens TD-145 turntable comes complete with a wide range of advanced features which it has in common with Thorens' top of the line TD-125 Mark II series: magnetic anti-skate control with the highly acclaimed TP-16 gimbal suspension tonearm; a high torque, slow speed, belt-driven 16-pole synchronous motor; dynamically balanced, seven pound, 12-inch non-magnetic die cast platter; front panel precision cueing control; split-level suspension system that reduces rumbl, acoustic feedback and vibrations.

The TD-145 C is still another reason why Thorens is th efirst name in turntable and thelast word in precision performance. The TD-145 is the perfect choice for the audiophile seeking the precision of a manual turntable combined with semi-automatic features.
