• Power cord (accessory section)
WE RECOMMEND THAT YOU SAVE ALL PACKAGING
MATERIALS FOR POSSIBLE FUTURE STORAGE, MOVING OR
SHIPPING.
Assembling the Turntable
The AT-PL120 requires some assembly before first use.
IMPORTANT: Do not connect the AC power cord until
assembly is complete.
Setting the Voltage Selector Switch
This turntable has the capability to be used with either 115V or
230V AC power, 50/60 Hz. The voltage selector switch is
located on the top of the housing deck, under the platter. Set
the switch according to the voltage in your area. [See Figure 4.]
(Note: The turntable comes shipped with the voltage selector
switch set for 115V AC.)
Setting the Pre-amp Selector Switch
For increased flexibility of use, this turntable has an internal
stereo phono pre-amplifier. The pre-amp selector switch
located in the rear-center of the housing deck under the platter
[See Figure 4], selects the internal stereo pre-amplifier (LINE
OUT), or bypasses the pre-amp (PHONO OUT) for use with
systems having specialized magnetic phono input jacks. The
audio output cable’s Red RCA-type plug is the Right channel;
the White plug is the Left channel.
If the system you are using has a PHONO input, set the
pre-amp selector switch to the PHONO OUT position and
connect the turntable’s output cables to the PHONO inputs on
your system, observing Red for Right channel and White for
Left channel.
If your system does not have a PHONO (magnetic phono) input,
set the pre-amp selector switch to LINE OUT and connect
the turntable’s output cables to the Auxiliary (AUX) or other
high-level inputs on your system, observing Red for Right
channel and White for Left channel.
When using the turntable with a computer sound card, set the
switch to LINE OUT and connect the turntable to the audio line
input on the computer sound card. Note: An audio adapter (not
included) may be required to interface the two RCA jacks of the
turntable output cable to the computer sound card input.
Assembling the Tone Arm
(Note: The headshell and cartridge are supplied pre-assembled
with the AT-PL120.)
1. Remove the vinyl tie used to secure the tone arm during
shipment. Temporarily secure the tone arm in the tone arm
rest with the locking clamp. [Figure 2, page 4, #24.]
2. Attach the headshell assembly by inserting it into the
socket at the front of the tone arm [See Figure 5.] (It’s
good practice always to hold a headshell assembly by the
left and right edges of the headshell to reduce the
possibility of damaging the stylus or disrupting the
cartridge wiring.)
3. While holding the headshell in position, rotate the
headshell locking ring counter-clockwise (to the left).
As the ring turns, it pulls the headshell into its seated
position. (Rotate the ring a full turn to the right to permit
removal of the headshell.)
4. With its black dial toward the front, use a screwing motion
to attach the counterweight to the arm extending back
from the tone arm pivot [Figure 2, page 4, #28]; the
counterweight will engage the spiral groove in the rear arm
section and move forward.
