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.

To use the SL-10, just place a record on the turntable, close the lid and press the start button. Stylus contact points are determined by a precision opto-electronic detection system. Perhaps the most amazing aspect is that the unit can be stood upright, as well as kept in the usual horizontal position, during record play. The SL-10 can also be stored in upright position, along with records, when not in use. An advanced coreless DC motor drives the arm and an optical sensor located near the stylus tip determines operation.
The opto-electronic system utilizes deflection angle detection and is said to be far more accurate than systems that operate near the suspension. Thus cartridge/groove geometry is always maintained near the ideal relationship, says technics. There is no lateral tracking error since the SL-10's linear tracking arm has the same geometry as the cutter heads used to make records.
