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.
