SL-102 broadcasting turntable
Due to its long experiences as well as to uninterrupted research and
development work, the factory is in a position to offer a comprehensive
range of broadcasting turntable designed to satisfy the requirements of
the most exacting broadcaster.
The large quantities manufactured have allowed to automate the
production to a large extent with the result of an extremely stable
high-precision mechanical contstruction keeping its characteristics for
many years of operation.
Studio turntable type SL-102 manufactured by Mechanikai Laboratórium
is an up-to-date device for studio quality record play-back using the latest
results in design and technology, offering outstanding features in technical
parameters, ease of handling and hihg operational safety.
Most important features:
1.
Direct drive system providing good technical parameters and a simple,
reliable
contstruction by minimizing the number of the moving parts and the
required driving energy.
2. Single lumped operating unit which connects the necessary operational
steps in logical sequence.
3. Automatic reverse positioning is one of the most exclusive feature of the
equipment. The record is automatically turned back exactly with an angle
which is necessary to reach nominal speed at a pre-selected point of the
groove, and since the output is muted until nominal speed is reached,
start
of playback can be pre-selected with an up-to-thesyllable precision. The
idea
and the circuitry needed to realise it, are patented.
4. Automatically muted, click-free sound output.
5. Built-in step noise absorber.
6. Electronic stroboscope (XTAL)
7. Easy and precisely adjustable stylus pressure and antiskating pressure.
8. Intensive sensor operated stylus lighting.
9. Built-in equalizer, amplifier and monitor loudspeaker (mono).
10. Stereophonic
monitoring provided.
