A Turntable with
Auto-Return Convenience

THE PL-4 IS AN AUTO-RETURN TURN-
table. All its essential controls - speed.
pitch control (with strobe). record size and
cut - are grouped on the slanted front
edge. Placing a record on the platter and
moving the tone arm over to it is all that is
necessary to enjoy record play. There's no
need to physically touch the tone arm at any
other time: the arm automatically returns to
its rest when play is over. Even arm cueing
is provided by an arm elevation device
located at the base 01 the arm.

The arm is straightcontoured and
constructed of low-mass PG (Polymer
Graphite). It is rigid, resistant to resonance,
and lightweight. Record warps. eccentricities
and cartridge/arm resonance pose no
obstacles to accurate tracking. Sensitivity is

increased by the lowmass design and
distortion is measurably reduced.

The PL-4 employs the Pioneer coreless
DC servo motor with Stable Hanging Rotor.
Designed without cores. slots and brushes.
it otters the smoothest cog-tree rotation.
Because oi electronic switching by Hall
elements. it does not generate switching
noise and years of reliable performance are
assured. Mated with this advanced motor is
an equally precise Periphery integration
speed detection circuit. It compensates for
the minutest error in rotational speed four
hundred times per second. The result is
impeccable short-term and long-term speed
accuracy.

Both the delicate cartridge and the tone
arm are protected trom acoustic leedback

by the Coaxial Suspension system which
mounts the motor and arm on a separate
subchassis. Neither air-borne nor floor-borne
vibrations are capable of affecting the tone
arm: its base is isolated lrom the cabinet and
suspended by four spring-loaded leet.

All in all. the PM is a tough act for any
competitive model in the same price range
to follow because 01 its high-value leatures
and top-flight specilications.
