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-1600

 Technics SL-1600 Direct Drive Fully Automatic Turntable

The SL-1600 features fully automatic play while incorporating the famous technics direct drive motor  and B.FG Servo One Chip IC control System.  The auto-mechanism permits auto start, auto retur, and auto stop, and will automatically repeat a record up to six times or indefinitely when the Memo-Repeat dial is set. A simple flick of the auto start lever automatically lifts the arm from the rest, places it on the record, returns it to the arm rest at the end of play, and shuts off the turntable.  Should you wish to stop play in the middle of a record, simply slide the lever to the stop position and the arm will automatically lift and return to the arm rest and the power will ashut off. With this handy automatic feature, The SL-1600 brings you the maximum in operating convenience with no compromise in turntable performance. 
 The motor of the SL-1600 is the incomparable Technics direct drive brushless DC motor which contains only one moving part, the rotor, which is also the platter. For motor drive and control this turntable employs our famous One Chip IC which is equivalent to 321 separate electronic components.  A B.FG (back-Electromotive-Force Frequency Generator) servo control reglates the speed and issues instant correction commands whenever necessary. The result; a spectacular wow & flutter of0,025% (WRMS), an inaudibly low rumble of -73 dB (DIN B).
 Rapid atarting time,full speed within 1/3 rotation of a turn and 0% speed variation up to 30 g tracking force. A number of measures are taken in the SL-1600 to isolate the motor, platter and tonearm from outside vibrations. The Floating Double Isolator insulates these important parts from most vibrations transmitted through the floor or the air.
 A heavy, aluminum diecast base, a heavy zinc tonearm base, a newly designed turntable mat, and precision made diecast aluminum cabinet also act to absorb vibrations and keep them away from the record platter and the tonearm. And speaking of the tonearm, it is gimbal suspended to ensure 7 mg friction. Effective arm mass has been kept very low (22 g) to accomodate premium high compliance cartridges. Other features include illuminated stroboscope, fine-scaled anti-skating device, independent pitch controls variable by up to 10%, viscous-damped cueing device and detachable dust cover.
