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-6

 No conventional turntable delivers the accuracy and control of this one. Technics SL-6  programmable Linear Tracking Turntable. The problem with a conventional turntable tonearm is that it ares across the record surface. So it is capable of true accuracy at only two points in its arc. Where the stylus is precisely aligned with the record groove.
Other Valuable Features.
Small details can make a big difference in reliability, convenience, and reproduced sound quality. That's why we've equipped the SL-6 with these valuable additional features:
30 cm (12") diameter aluminum die-cast platter
Full cycle detection FG servo mechanism
Built-in 45 rpm adaptor
Tonearm position indicator LED and scale
All front panel  controls with electronic soft-touch switch
Isolator feet
Manual speed selection possible for playing nonstandard discs

Turntable/tape deck synchronized play capability.
 The Technics SL-6 Linear Tracking Turntable goes beyond that . It actually duplicates the straight-line motion of the cutting arm that originally mastered the record. This enables the Technics SL-6 to deliver true accuracy at every point on the record. First note to last. There is none of the tracking error, skating force error or distortion that accompanies a traditional tonearm.
And the SL-6 ensures this accuracy with some outstanding technological advances. Including a microcomputer controlled system that constantly monitors the stylus-to-groove angle and automatically makes corrections.
But linear tracking is just the beginning. There's the precise control you get with the Technics random access programmable microcomputer. At the touch of a button, you can set the SL-6 to play any selections you want, in any order. You can even repeat or skip selections.
There are still more features that help the Technics SL-6 perform so impeccably. A precision direct-drive motor . Sensors that automatically select the correct playing speed.
Our patented P-Mount plug-in cartridge system delivers optimum tonearm/cartridge compatibility along with simplified about the size of a record jacket.
Accuracy, control and musical pleasure beyond the conventional. The Technics SL-6 programmable Linear Tracking Turntable. Just one of the sophisticated and "inteligent" turntables from Technics.
 Superb Basic Performance
Through direct drive. Technics offers you uncompromising rotational precision and reliability. Our integral rotor-platter design eliminates extra parts and assures stable operation, since the turntable platter is part of the direct drive motor itself. You can hear this superior performance for yourself. You can also confirm it with the specs.

The Technics linear tracking tonearm enjoys a number of advantages, the most important of which is an optoelectronic deflection angle detection system located near the cartridge (not at the rear end of the tonearm). This constantly monitors stylus-to-groove angle and sends this vital data to the microcomputer (which makes tiny corrections as necessary). The tonearm's gimbal suspension system increases sensitivity. A low-friction slide bearing reduces vibration and assures precise tonearm support. Furthermore the tonearm is dynamically balanced, so it doesn't depend on gravity alone to maintain correct tracking force. This system also improves the tonearm's ability to track warped records.
 Automatic Convenience
With the SL-6 the turntable takes care of everything, including record size and speed selection for all standard discs. Also the SL-6 is virtually foolproof. You can't set the tonearm down on an empty platter. You never even touch the tonearm, so the cartridge, stylus, and grooves are safe from accidents and mishandling.

Designed for Today's Living Space.
Whether you have a spacious loft or a studio apartment, you'll appreciate the way the SL-6 fits where other turntables won't in fact, you can't make a turntable significantly smaller than this because it must be at least 12'' wide to properly accommodate an LP. compact size isn't the only thing that makes the SL-6 easy to install and easy to live with. For one thing, the tonearm is dynamically balanced so you don't need the perfectly level surface that is required for a statically balanced design.
Also the base of the SL-6 is made of TNRC, a nonresonant compound damps resonances, and helps avoid acoustic feedback or howling.  In other words the turntable and tonearm are well isolated from the outside. Therefore, the cartridge can retrieve maximum information from the record grooves, with a minimum of interference.
 Plug-in Cartridge Connector
If you've had much experience using a conventional tonearm, then you know how much trouble it is to mount and change cartridges.
Technics developed the plug-in connector system to eliminate this difficulty, and improve performance at the same time. To use a plug-in connector cartridge, you simply plug it into the end of the tonearm and surface it with a single screw.  There's no headshell, no tiny lead wires, and no adjustments of any kind. Not even tracking force. Mechanical and electrical connection is precise and tonearm-cartridge matching is perfect because everything is standardized by Technics
