SL-1950
Introducing
Technics SL-1950. the changer that outperforms all of our competitors' changers
and many of their high-prieced manuals. Because it's the changer with the
Technics direct-drive system. The system radio stations use and discos abuse.
The SL-1950
gives you performance comparable to our direct-drive manuals. Like inaudible
wow and flutter at 0,03% WRMS. Undetectable rumble at -70 dB (DIN B) and a 321
element one-chip IC that autamatically stabilizes turntable speed.
To take
advantage of all that accuracy, the SL-1950 features a sensitive, statically
balanced S-shaped tonearm.
But even
though the SL-1950 performs like a manual, it's still a changer. It handles
up to 6 records automatically. And has a
memory system that allows repeated or continuous paly in both the single-play
and changer modes.
And that's
not all. The SL-1950 also has oil-damped cueing. Anti-skating control.
Illuminated stroboscope . Pitch controls variable by 10%. Feedback-insulated
legs. A hinged, detachable dust cover. And an anti-resonant integral base.
The SL-1950
- The changer you should look at even if you're looking for a manual.
High
peformance automatic turntable system
The
"mem0-gram" function unique to technics which enables you to enjoy
manual play, auto-start, auto-return, auto-stop, repeated performance from 1 to
6 times and continuously performance, and , in addition, multiple play, capable
of playing 1 to 6 records continuously. All these features will make your
"audio life" happier.
Integral
rotor-platter structire
First to
introduce the direct-drive system for turntables, Technics has now taken this
remarkable advance one step further with the development of the integral
Rotor-Platter structure. This latest technics breakthrough combines the
turntable platter and the rotor of the motor in one piece, reducing the number
of moving parts to just one, to further simplfy turntable construction and at
the same time raise performance standards.
Simplified design and construction make possible more precise and
accurate speed, greater reliability, and more attractive styling; and most
important, measurable performance that is unegualled among turntables with
other drive systems.
Dependable
one chip IC.
The
direct-drive motor of the SL-1950 is controlled by a "one-chip" IC
which performs the functions of up to 321 individual transistor, diode and
resistor elements. With this IC brain, the motor control circuit supplies
precisely the correct amount of drive current to the motor to maintain the
proper speed under all conditions.
This
"one-chip" control system contains a number of refinements which
assure unvarying rotational speed,, free from "tag" in corrective
response. Rotation stability is unaffected by changes in temperature or long
playing times, and the IC permits quick response to sudden transient in load.
Hi-fidelity
performance with rumble (Signal-to-Noise ratio) of -70 db (DIN45539B), wow and flutter of 0,03% (WRMS)
The
ultra-low speed brushless Dc motor employed in this unit has an extremely low
power consumption of about 0,1W. The high performance of the Direct Drive motor
is due to the newly developed heavy weignt base and to the utilization of the
one chip IC of the B.FG (back Electromotive Force Frequency Generator} system.
