@ Total quartz locked continuous pitch
adjustment about +8%
Quartz-phase-locked control means aimost 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-1200MK2, however, pitch is variabie con-
tinuously (analogically) by up to approximatly +8% under
total quartzlocked control. The pitch is controlled with a
large sliding lever, located to the right of the turntable
piatter.
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 which has excelient vibration resistance and
absorbing characteristics. The turntable platter is also vibra-
tion-damped with specially fabricated 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 the SL-1200MK2 ideal for use with
extra-high sound pressure levels.
@ High torque for fast starts
The integral rotor/platter motor delivers 1.5kg-cm (1.3 Ib-in)
starting torque. This high torque gives very quick starts
enabling the platter to reach 33-1/3 rpm within 0.7 s. (a
quarter of a turn). This is a big advantage in many
professional applications where fast cueing is a necessity.
@ High sensitivity, low mass, gimbal suspen-
sion tonearm
The highly sensitive tonearm features a genuine gimbal
suspension, the rotational center of which is precisely
defined at one point. Bearings are finished to a tolerance of
+0.5 microns. This, and the extra-closeness of pivot center
to the bearings, result in the minimal friction of 7 mg (0.007
g) for both horizontal and vertical movement. Add to this the
low 12-gram effective tonearm mass (including headshell,
without cartridge) and you have a tonearm compatible with
the wide range of compliances found in today’s cartridges. If
you choose a popular high compliance MM cartridge, the
low range resonance frequency will appear in the correct
area to avoid warp frequencies of records, but without
entering the low end of the audio spectrum. This tonearm is
provided with a computer designed, light-weight, high-
rigidity headshell made of single-piece diecast aluminum to
resist partial vibration. The universal design atlows
headshell interchangeability. Contacts are gold-plated.
