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.

Sansui SC 3000

Front-Loading Stereo Cassette Deck with Dolby
Sansui was not the first to introduce the front-loading format which appeared in stereo cassette decks a season or so ago. And for a very good reason; we left that its obvious advantages were too often offset by poor tape transport stability and reduced tape-handling convenience.
Our engineers kept both these points in mind as they created the prototype of the front-loading SC-3000. the results prove that the wait was worth it. Thanks to the use of a superior tape-transport mechanism, our all-new Sc-3000 has a very high Signal-to-Noise ratio (50 dB with Dolby off) and low wow/flutter (0,09%) and because its front access tape compartment is positioned right-side-up (unlikesome other front-loading decks) you can easily read tape lebels and observe tape movement for improved tape-handling convenience.
Numerous other features - like the built-in Dolby, full auto-stop, memory rewind, selectable tape, separate output level control, LED peak-level indicator and others - make the SC-3000 a very attractive deck for its price.

Newly Perfected Front-Load Format
The front-loading design of the SC-3000 lets you stack if under of over other components in your stereo system, saving space and handling time. The tape compartment is right-side-up so that cassettes are inserted and locked in place with their slotted edges down (in "normal" position). A new fail-safe insertion device developed by Sansui prevents damaging misuse, and a built-in light lets you read labels and see tape motion in a darkened room.
Removable Compartment Lid - the sturdy metal and plastic lid on the tape compartment can easily be removed giving you plenty of room for head maintenance.

Electronic DC Servomotor
This highly dependable Dc motor features high torque performance and long life. It is governed by a special electronic system for constant speed regulation regardless of changes in voltage supply or tape loads.
Independent Capstan Drive
Sansui's special design separates the capstan drive from the reel drive. The former has a high-inertis fly-wheel to keep capstan rotation smooth and even. The system also prevents capstan torque from affecting tape speed when loads vary. Very low wow/flutter performance is assured with the use of a mirror-finished slip-free drive belt of perfect flatness.
Full Auto Stop/Shut-Off
An electronic magnet/lead switch mechanism senses tape motion and immediately disengages the drive motor and returns all operating levers to the Stop position when your tape reaches either end.
Super-Hard permalloy Head
Sansui uses this special recording/playback head of super-hard permalloy material because it resists wear longer (up to ten times longer, in fact) than conventional permalloy types yet retains the permalloy advantages of low distortion and high musical performance quality.
