[. . . ] With the SL-P1200, however, pitch is variable continuously (analogically) by up to ±8% under total quartzlocked control . The pitch is controlled with a large sliding lever, located to the right of the turntable platter . Four lines of platter markings are also provided indicating +6%, +3 . 3%, 0% (exact rated speed) and -3 . 3% change from rated speed . Aluminum diecast cabinet and special heavy rubber base material provide acoustic isolation The effects of external vibrations are dramatically reduced in the turntable by this new turntable construction . And the underside of the main base is made of a heavy rubber material (special one-piece molding) which has excellent vibration resistance and absorbing characteristics . The turntable platter is also vibration-damped with specially fabricat rubber matting in the underside along with the thick turntable sheet (rubber mat) . Four large-size insulating feet also help to absorb unwanted vibrations . These features make SL-11 200MK2 ideal for use with extrahigh sound pressure levels . High torque for fast starts The integral rotor/platter motor delivers 1 . 5kg-cm (1 . 3lb-in) starting torque . This high torque gives very quick starts enabling the platter to reach 33-1/3 rpm within 0 . 7 s. This is a big advantage in many professional applications where fast cueing is a necessity. Counterclockwise rotation -distance between the record and stylus tip is increased . Note : As the adjusting screw has hexagonal head, be sure to make the adjustment while depressing the arm lift, or the screw will not move freely . Also be sure that the hexagonal head retracts correctly into the arm lift when the latter is released . ADJUSTMENTS Adjustment of the tonearm height (See Fig . 22 . ) The height of the tonearm can be adjusted up to 6 mm, and a scale is provided on the adjust ring in 0 . 5 mm increments . Be sure to set the proper arm height using the adjust ring scale and referring to the table .

This weight, iminum vs head- For example, if the cartridge height is 17 . 5 mm, the armheight adjust ring should be positioned at the intermediate location between 2 and 3 on the scale . 22 . ) Caution : Be sure to lock the tonearm by turning the arm lock knob in the direction indicated by the arrow after finishing the height adjustment for the tonearm . 23 . ) Apply 2 or 3 drops of oil once after every 2000 hours'of operation .
