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.

Technics SL-1100AC

 Technics SL-1100 AC Direct Drive Turntable

The SL-1100AC provides that incomparable professional technics quality in a reasonably priced package. The heart of this outstanding direct drive turntable is its DC brushless motor which drives the platter directly to eliminate belts, pulleys, and idlers. This simple design means fewer moving parts to wear out and greater long term reliability. The motor is controlled electronically by a DC servo which provides highly accurate rotation completely unaffected by power line frequency and voltage variations.
 And due to its high torque, speed remains the same even during changes of external drag. This combination produces wow & flutter of  0,03% (WRMS) and rumble of better than -70 dB (DIN B).
The turntable is dynamically balanced and of extra large size (35 cm/13-25/32") and weight (2 kg/4,4lb.) to contribute to overall high performance.
 The tonearm is static balanced low mass tubular with a length  (pivot to stylus) of 235 mm (9¼") for to tracking error. Effective arm mass has been kept very low to accommodate high compliance cartridges.  The headshell is made of precision diecast aluminum with the universal type connector.
 Other features include independent pitch controls variable ±5%, illuminated stroboscope, feather-touch start/stop buttons, viscous-damped cueing, anti-skating device, feedback insulated legs, diecast aluminum base, detachable dust cover, and two AC outlets (one for stroboscope).

Technics SL-110A
Identical in every respect with model SL-1100AC, but without tonearm. Metal tonearm panel permits installation of any tonearm. Transparent dust cover supplied.
