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.

BIC 960 turntable


The new BIC programmed Turntables are engineered to do things no other turntables can do. In the face of more demanding cartridge designs and critical new 4-channel discs, the BIC 960 appear at just the right moment.

The mechanism that turns your records and carries your cartridge has become an increasingly critical part of your audio system. More than ever before, today's turntable buyer is faced with a classic dilemma - Should I buy a single-play manual turntable for its playback superiority? Or - Should I buy an automatic for its superior record-handling capabilities?. Until now, he dilemma has remained.

British Industries Co., creator and builder of the new BIC turntables has been the major innovator in this field since 1936. no company has better credentials or greater experience with record plauback equipment in the components field. The best proof of that is the instruments which BIC now introduces; The 960 (and 980) unique turntables, they have been engineered to solve once and for all the "manual vs. automatic" dilemma.

They are belt-drive as opposed to all automatic changers which drive the platter via an intermediate idler wheel.

They are powered by a 24-pole, low speed (330 rpm) motor while most automatics use 4-pole, high rpm motors. In all three areas of function  - platter drive, tone arm system, and multiple play capabilities, the BIC turntables offer refinements and advances which set them apart from everything else in the market. As a matter of fact, several BIC turntable features are not be had on any other instrument at any price.

 


The BIC 960 is identical to its companion,the 980, except for the 980's electronic drive, pitch control, and lighted strobe . You have probaly alredy noticed its low profile. This is not an optical illusion or a styling trick. The 980 (and 960) are indeed as low and trim as they appear. This lack of bulk is your first clue that the BIC turntables are not merely manuals with automatic features added, that they are in fact "originals", designed from the start to be simple, as only sophisticated engineering can make them.

Moving parts found in conventional automatics have been eliminated right and left. In the process, potential sources of malfunction have disappeared. Potential sources of noise and vibration have also been eliminated.

 

Operating controls are grouped in a single program panel on the right side of the unit. To say that this panel brings new logic to the turntable and new refinement and simplicity to its operation, barely does it justice.

The tone arm incorporates several dramatic improvements which set it apart from all others.

And of course you have noticed at the bottom a cutaway drwing of the BIC platter which reveals the belt-drive mechanism. No other turntable which can play morethan a single record offers belt-drive and all its advantages. The drive system alone sets BIC turntables apart. But there's more.

 


The turntable are built entirely in the U.S.A made parts. They are built in BIC's own plant where all aspects of manufacturing are in BIC's hands. They are the first fine turntables of their type built in this country, and they meet come to expect only from imported equipment. Beyond what that means in technical terms, they do not come to you burdend with import duties or fluctuating exchange rates.

They are rugged. They are built of the best materials that can be had.
