Mount the PU base plate onto the arm base and cit~ck the spring position . 4 SL-P1200 Total quartz locked continuous pitch adjustment f8% Quartz-phase-locked control means almost perfect accuracy of turntable rotation . But with most quartz turntables, this accurate control circuit must be cut out when the pitch control is employed . 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 . The turntable base is precision-made aluminum diecast. 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) . " Technics integral rotor/platter motor construction with full cycle detection FG . )MK2 lections want it . nto the SL-P1200 Pitch control (fine adjustment of speed) (See Figs . 18 and 19 . ) When the pitch control knob is located at the center of the position after turning on the power, the green LED indicator is lit showing the operating condition for the predetermined speed (either 33-1/3 or 45 rpm) . The pitch control is variable in a range of 0-±8% . Adjustment should be done on the basis of indicator scale . Figures on the indicator show approximate percentages for variable pitch control . When the strobe dots in 4 stages marked at the peripheral edge of the turntable appear to be stationary, variation of individual pitches is shown . 19 . ) Note : The strobe-illumination of this unit employs a strobe-illuminator LED synchronized with the precise quartz frequency . For fine adjustment of the turntable speed, be sure to effect the adjustment according to the LED illumination . The LED illumination is not synchronized with fluorescent lamps .
