Reference excerpt

The Technics SL-10 is a direct-drive, linear tracking automatic turntable, which was produced from 1979 to 1985.

Features The SL-10 was the first linear-tracking turntable to feature direct drive, a Technics innovation dating back to 1969 with the SP-10 Mk I. The SL-10, along with its fully programmable stablemate the SL-15, was able to penetrate the consumer electronics market much more effectively than any preceding linear-tracking turntable, and it spawned a wave of imitators throughout the 1980s, along with many derivations by Technics itself. Unlike many of the inexpensive designs that followed it, the SL-10 is cast from aluminum and weighs 6.5 kg (14 lb). Its chassis is the same size as a standard LP jacket, doing away with the large plinth, visible tonearm and general bulk associated with conventional radial-tracking turntables that the public was familiar with up to that point. The SL-10 came equipped with the Technics EPS-310MC moving-coil cartridge. Due to the low output of the moving-coil cartridge, the SL-10 includes a built-in, bypassable step-up preamp to allow it to connect to standard phono inputs. The original Technics EPS-310MC moving-coil cartridge was designed to be replaced as a unit; the stylus was not removable. The cartridge has since been discontinued; the SL-10 will accept any P-mount/T4P cartridge. The SL-10 is capable of being powered by an external DC power adapter or a standard AC power supply. The motor is quartz-locked, providing accurate rotational speed. Perhaps the SL-10's most unusual feature is its ability to play records in any position, even in a vertical position. In fact, records could be played upside down with the lid closed; the SL-10's internal disc clamp holds the record in place, and the tonearm, being dynamically balanced, maintains a consistent tracking force regardless of the turntable position. An example of the SL-10 is in the collection of the Museum of Modern Art.

Worked examples

Example 1 — a first encounter with Technics SL-10

Start with the simplest possible case. Write down what Technics SL-10 claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Technics SL-10 before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Technics SL-10 ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Technics SL-10

In research: Technics SL-10 appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Technics SL-10 in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Technics SL-10 is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1981 musical instruments, DJ equipment, Electronic musical instruments, so understanding it makes those chapters shorter.
In everyday life: Look for Technics SL-10 outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
