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 speakers are 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-105 Mk2

 The Thorens TD 105 semi-automatic high fidelity turntable incorporates advanced technical features to afford true state-of-the-art. Performance.
It employs a special Thorens suspension system for the floating chassis. The exclusive Isotrack tone arm with precision bearing assembly and low-mass construction enables optimum tracking characteristics to be realized with modern pickup cartridges.
 The TD 105 also employs a velocity-sensitive electronic shut off which raises the tone arm, returns it to its rest, and stops the motor. The electronic shut off at the end of a record operates without frictional contact with the tone arm, ensuring precise performance and full protection of the record and pickup stylus.  All operating functions are initiated by electronic switching keys which respond to a light touch of the finger.
