Initial Setup
Setting the Pre-amp Switch
For increased flexibility of use, this turntable has an internal
stereo phono pre-amplifier. The Pre-amp Selector Switch
is located under the turntable platter, in the rear-center
(Fig. 1). If the system amplifier you are using has a PHONO
input, set the Pre-amp Selector Switch to the OFF
position. If your amplifier does not have a PHONO input,
set the Pre-amp Selector Switch to the ON position and
connect the turntables output cables to the AUX or other
high-level input on the amplifier (described later).
Assembling the Turntable
1.
Carefully place the turntable platter on the center
spindle, making certain the platter is fully seated on
the spindle.
2.
While holding both ends of the red tape ribbon on the
turntable belt, carefully pull the belt over the motor
pulley (Fig. 2a). (If the belt drops off, remove the
turntable platter and put the belt back on it, as
described on page 6.)
3.
Once the belt is seated in the pulleys groove, carefully
remove the ribbon. Make certain the belt is not
twisted.
4.
Place the turntable mat on top of the turntable platter
(Fig. 2b).
5.
If desired, the hinged dust cover may be removed.
Hold both sides of the dust cover and pull upward
gently and evenly to detach the cover from the
turntable (Fig. 2c). Keep the cover in a safe, clean
place.

/
3
rpm or 45 rpm (Fig. 6).
5. Start: Gently push the START button (Fig. 7a). The
turntable will start and the tone arm automatically will
move to the lead-in groove. When the record has fin-
ished playing, the tone arm automatically will return to
the tone arm rest and the turntable will shut off.
6. Stop: To stop playing the record before it reaches the

lift and return to the tone arm rest, and the turntable
will shut off.
7. Pause: To pause the record before it has completed
playing, press the tone arm Lift button (Fig. 7c). Press
the Lift button again to continue playing the record.
Connecting to Stereo System
1.
Connect the red RCA-type pin-plug to the right channel
input and the white RCA-type pin-plug to the left
channel input of the amplifier. Fig. 1, page 3.)
2.
With the tone arm still fastened to the tone arm rest,
slowly turn the turntable platter clockwise ten times,
to make certain the automatic mechanism is fully
cycled.
3.
Remove the vinyl tie that holds the tone arm on its
rest.
4.
Connect the power cord plug to an AC outlet.
Connecting to Computers or Audio Devices with 3.5 mm
Input
The AT-PL50 connects without adapters to devices equipped
with RCA connectors. For maximum flexibility, we have
included two adapter cables to fit other popular audio inputs.
The first of these adapter cablesdual RCA to stereo 3.5 mm
mini-plug (male)is designed to fit most popular computer*
audio inputs. It may also be used to connect the turntable's
RCA output to other equipment, including:
a stereo/boombox* equipped with a 3.5 mm mini input
powered speakers* equipped with a 3.5 mm mini input
a mixer* or PA system* equipped with a 3.5 mm mini jack
The second included adapter cabledual RCA to stereo 3.5 mm
mini-plug (female)permits connection of the turntable output to
amplified speakers* or similar devices. The 3.5 mm stereo mini-
jack on the cable adapter accepts stereo mini-plugs.
On both cables, the tip carries the signal for the left channel,
the ring carries the right signal, and the sleeve is
ground/common.
To use either adapter cable, connect the turntable's red and
white RCA-type plugs to the cable adapter's RCA-type jacks.
* When using either cable adapter, always set the AT-PL50
turntables Pre-amp Selector Switch to the ON position.
(Switch is located under the AT-PL50 turntable platter.)
NOTE: If connection is desired to a mono amplifier/speaker,
make certain to use a stereo-to-mono adapter, available from
your dealer or an electronic parts store. Inserting a mono plug in
the stereo jack will disable one of the stereo channels. Other
adapter cable configurations will be available from dealers and
parts stores for connecting to devices needing different
terminations.

Replacing the Stylus
While holding the head of the tone arm, rotate the front of the
stylus assembly in a forward and down motion to remove it
(Fig. 8). (As you remove the old assembly, note its position and
feel, to aid in properly installing the new one.)
Install the new stylus assembly as shown in Figures 9a/9b,
being careful not to touch the actual stylus. Make certain that
the projection at the back of the assembly is fully seated in the
cartridge body first (Fig. 9a), and that the assembly clicks up
into place, with no gap between its top edge and the front of
the black plastic tone arm head (Fig. 9b). Replace the stylus
after 400 hours of use.
To maintain original performance, insist upon a genuine
Audio-Technica brand replacement stylus. Look for the
Audio-Technica trademark ( ) on the front of the stylus
assembly and on the packaging.
