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-5

 Technics new linear-tracking SL-5. with plug-in cartridge capability made affordable. Just place the record on the platter, close the cover and press start. Everything else is automatic, including the pleasure.
 Utilizing the same linear-tracking concept featured in the renowned Technics SL-10 and SL-15. technics now introduces both the album-sized SL-5 and the compact SL-DL5. each of these two new models offers you the same incredible performance and uncanny accuracy of technics linear-tracking at prices equal to many of today's conventional turntables.
 Both feature Technics plug-in cartridge system, so installation is always easy, exact and precise. Best of all, the music won't be distorted by improper mounting.
This model also offers technics direct-drive motor. Dynamically balanced tonearm with gimbal suspension. Aluminum die-cast platter. Tonearm position indicator LED and scale to show the precise location of the tonearm on the record. Abuilt-in muting circuit to eliminate "cliks" and "pops" when the stylus makes contact with the record surface. Plus convenient front panel controls.
 Technics Linear Tracking and How it Differs
The best testimony for the linear tracking concept is its use in mastering lathes. Record manufactures use linear tracking to meke records, so it's obvious that it is the best method available to play them back. The point is simple, linear tracking tonearms play the records ezactly as they were originally cut. Therefore, tracking error is completely non-existent, and distortion becomes a notion with meaning only on the test bench. So if linear tracking arms share  these attributes, why should you choose technics?
One reason is the dynamic balance system - it makes certain that tracking force is always precise and accurate. Plus, Technics incorporates a very sophisticated optoelectronic deflection angle detection system, governed by microcomputer and constantly monitored.  You can therefore be sure that the stylus is always at the precisely correct angle to the grooves. A potential source of inaccuracy and distortion is thus removed. And we designed the tonearm system with painstaking attention to detail - a gimbal suspension system increases sensitivity, and a low-friction slide bearing reduces vibration and assures precise tonearm transport.
 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 912"0 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.
