I FEATURES

Encounter two separate isolation stages. The first stage
effectively damps out harmful external vibrations which
may reach the unit through its resting surface. The all-
important turntable, motor and tonearm assembly are
then supported on a second isolation system. These
isolators are specially designed with material and springs
of calculated, finely-tuned elasticity to absorb external
vibrations.

Isolation from feedback lets you enjoy clear, transparent
sound even at high volume levels.

Technics unique motor construction in which the rotor
of the motor is integrally formed with the turntable.

High torque motor delivering 1.5kg-cm makes it possible
to reach 33-1/3 r.p.m. from standstill within 0.7 sec.
(1/4 rotation) and to effect instantaneous speed change.
(Fig. 1).

Superior load characteristic of 0 rotational deviation
even at a stylus pressure of 300 9. (Fig. 2).

High performance with wow and flutter of only 0.025%
(JIS C5521) and rumble of -73 dB (DIN 455398).
Since the development of the DD turntable, Technics
has continually strived for further improvement of
player performance and has introduced numerous high
performance models on the market.

The SL-l300MK2 series is brought into being by com-
bination of experience and research.

The characteristic values of rumble -73 dB (DIN
455398) and wow and flutter of 0.02 % (W.R.M.S JlS
C5521) by far exceed the standards to which record
albums are made.

Quartz Controlled Rotation Accuracy

The SL-l300MK2 utilizes the oscillation of a quartz cry-
stal as a reference signal or source. This oscillation is not
affected by temperature change or power fluctuations.
By synchronizing the rotation of the turntable platter
accurately to the reference signal, speed drift of the SL-
1300MK2 is held within i0.002%. This means that for a
record with a playing time of 30 min, total playing time
variation can amount to no more than 0.036 sec. This
stable and accurate rotation sets a new standard of pre-
cision.

The accuracy under controlled operating conditions as in
a listening room is about 1.000001% as shown in Fig. 3.

Highly sensitive universal tonearm.

For the finest tracking sensitivity, the tonearm rests in a
gimbal suspension equipped with two pairs of low fric-
tion pivot bearings. Gimbal suspension and low tonearm
mass means that accurate tracking is possible at tracking
forces as low as 0.25 grams. With enhanced rotational
sensitivity of 7 mg. the tonearm is allowed free, gyro-
scopic movement to ensure flawless balance during
tracking. The longer-than-usual effective tonearm length
(9-1/16" or 230 mm, stylus to pivot) contributes to the
arms low tracking error, and this in turn facilitates the
design of the anti-skating control for precise and reliable
tracking. With this design, a single precise anti-skating
scale counteracts side thrust for all types of styli.

Arm height is adjustable within a range of 6 mm to ac-
comodate varying cartridge dimensions.

Resonance dampened headshell with unique overhang
adjuster.

Low capacitance phonocables.
