D.R.E.S. tha BEATnik's Hip Hop History Fact 4 of 30!!!

Today we'll highlight One of the Most Important Instruments in Creating and Crafting this Culture of Hip Hop. It has been heralded as the "the most important musical instrument of the last two-and-a-half decades." Fans of the Culture have tried to stray away from it but It simply isn't Hip Hop without it!!! I'm speaking about the Turntable. And today We'll be speaking about the TECHNICS SL-1200 DIRECT DRIVE TURNTABLE.

The Technics SL-1200 are a series of turntables manufactured since October 1972 by Matsushita under the brand name of Technics. S means "Stereo", L means "Player". Originally released as a high fidelity consumer record player, it quickly became adopted among radio and club disc jockeys.

Check Out the Breakdown of the Ingredients of the Direct Drive Motor
  1. Power Supply
    First the power will be converted from 220V (*) to 30V AC.
  2. Power regulation
    After that it's regulated down again to a steady 21V DC by this separate Regulator. It's mounted with conductive paste to the chassis so it directs all heat that is created in this process away from the electrics.

    The 21V is used for the Stroboscope, Popup Light (official name : Stylus Illuminator), Turntable Drive processor IC101 and the pitch control circuits around IC302.

    From this 21V also a 9.4v stream is created to feed the other electronics (mainly the pitch circuits around IC301 and the separate fader panel).
  3. Control Section: Strobe, Pitch, Play/Stop
    The leads that leave the mainboard are connected to the Main Controls of the SL1200 and take care of Play and Stop function, the Strobe Light and the Speed Selector function.
  4. Stylus Illuminator
    The 2 wires that go into the chassis go to the Popup Light (Stylus Illuminator) and supply it's power. Be careful : the plug that connects these wires to the mainboard is located near the Power Regulator circuits at the back-end of the circuit board.
  1. Pitch Control
    Feeds the setting of the Pitch Fader back to the Drive Control IC and supplies the 0% LED with power.
  2. Direct Drive Coils
    Direct Drive gives you more torque at a continuous level in comparison to belt driven systems. In this center unit are the coils that measure the position of the Platter and also the coils that drive the Platter. All calculations are done in the 3 ICs of the SL1200.
  3. Pitch Control IC301
    Makes calculations to translate the setting of the Pitch Fader to a certain change in rotation speed of the Platter.
  4. Pitch Lock IC302
    Makes the calculations with the Quartz Clock to assure you a steady pitch.
  5. Control IC201
    These are actually the brains of your SL1200, from this IC all electronics are controlled and operated.
  6. Turntable Drive IC101
    If IC201 equals the brains, IC101 must be the heart of the turntable as it controls the electronic fields that make the Platter rotate.
    Via 3 detection coils the IC measures the positions of the Platter, in reaction to this, the 3 drive coils are triggered to create torque on the Platter.

While it is possible to tell the year (and the month) when the SL-1200 was manufactured from the serial number on the back or bottom of the turntable. SL-1200 serial numbers are in two different formats, depending on the date of manufacture. It isn't exactly possible to determine the decade in which the SL-1200 in question was manufactured, as the serial number contains only the last digit of the year. If the year digit is 8, the turntable may have been manufactured in 1978, 1988, 1998 or 2008. If the year digit is 0, the turntable may have been manufactured in 1980, 1990 or 2000. One rule of thumb is that old-format serial numbers belong to SL-1200s manufactured during the 1970s and 1980s, while new-format serial numbers belong to SL-1200s manufactured during the 1990s and beyond.

Old-format serial number: NHOJF20765 (SL-1200 manufactured 1982) The first digit shows the year when the turntable was manufactured. These serial numbers contain no indication of the month of manufacture. It should be noted that serial numbers in this format contain no letters following digits.

New-format serial number: GE4FB001154 (SL-1200MK2 manufactured June 2004) The first digit shows the year when the turntable was manufactured, while the month of manufacture is indicated by the letter following it. Months are coded as letters between A and L inclusive; A indicates January, B indicates February, and so on, so F indicates June.

Since its release in 1978, SL-1200MK2 and its successors have been the most common turntable for DJing and scratching. The MK2 presented several improvements, including to the motor and casing. Since 1972, more than 3 million units have been sold. It is widely regarded as one of the most durable and reliable turntables ever produced.

Then on November 1 2010, the Unthinkable happened...
Panasonic reactive statement - Production of analogue turntables has ceased
Panasonic has confirmed that it ceased the production of its Technics-branded analogue turntables this autumn. After more than 35 years as a leading manufacturer of analogue turntables, Panasonic has regretfully taken the decision to leave this market. However, Panasonic will continue to sell headphones under the Technics brand. We are sure that retailers and consumers will understand that our product range has to reflect the accelerating transformation of the entire audio market from analogue to digital. In addition, the number of component suppliers serving the analogue market has dwindled in recent years and we brought forward the decision to leave the market rather than risk being unable to fulfill future orders because of a lack of parts. Panasonic employees who have been working on the analogue turntable range have been redeployed elsewhere within Panasonic - many of them continuing to work in Panasonic´s Audio Video Business Unit.

What simply was created to play Records turned out to be a Formidable Instrument that changed the landscape of not just Music but the World!! The Turntable is a Legitimate instrument. All over the World The Turntable outsells the Guitar as the #1 Instrument of Choice!! Which is why Today we Pay Homage to The Turntable a Vital Instrument to the Advancement of the Culture of Hip Hop!!! My name is D.R.E.S. tha BEATnik and this is My Hip Hop History Fact #KNOWYOURCULTURE!!
