Assembling the Turntable
The AT-LP120-USB requires some assembly before first use. IMPORTANT: Do not connect the AC power cord until assembly is complete.
Setting the Voltage Selector Switch
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-LP120-USB.)
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, #23.]
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, #27]; the counterweight will engage the spiral groove in the rear arm section and move forward.
Figure 5 – Headshell
This turntable has the capability to be used with either 115V or 230V AC power, 60/50 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.)
Figure 4 – Voltage Switch
Voltage switch
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 rearpanel of the turntable [See Figure 3, page 4, #29], 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.
Assembling the Turntable Platter and Slip Mat
1.Carefully place the turntable platter on the center spindle, making certain the platter is fully seated on the spindle. [See Figure 6.]
2.Place the soft black slip mat on top of the platter.
Figure 6 – Platter and Slip Mat

Initial Setup (continued)
Assembling the Dust Cover
1.Insert the T-shaped ends of the dust cover hinges into the two hinge receptacles located at the back of the turntable housing. When properly installed, the flat part of the cover hinges should be facing away from the turntable housing at about a 45° angle.
2.Holding the dust cover over the turntable, carefully guide the cover
hinges into the two slots molded into the rear of the dust cover. The springs in the hinges allow the cover to be held open at about a 45° angle if desired. (Note: There is only one “open” position; the hinges do NOT permit the cover to stand “straight up.”)
3.To remove the dust cover from the turntable, gently disengage the hinges from the slots in the cover. This is usually easier when the cover is in the “closed” position. Slowly and carefully lift straight up until the cover is clear of the unit. The hinges may then be removed from the turntable base, if desired.
Setting Tone Arm Balance and Tracking Force
To allow the cartridge to properly track in a record, the tone arm balance and tracking force must be carefully set to the cartridge manufacturer’s specifications. Failure to properly set up the tone arm assembly can cause damage to the cartridge stylus and/or records.
(Note: Once the stylus protective cover has been removed and the tone arm locking clamp has been released, take extreme care not to damage the stylus. Do not allow it to drag or scrape across the slip mat.)
Tone Arm Setup:
1.Set the anti-skate adjustment to “0”. [Figure 2, page 4, #26.]
2.Remove the clear protective stylus cover, carefully sliding it straight forward, off the front of the cartridge.
3.While gently holding the headshell to stabilize the tone arm, release the tone arm locking clamp. At this point, the tone arm is unbalanced and free to swing.
4.While gently holding the headshell, carefully rotate the counterweight until the tone arm is horizontally balanced and hovers freely just above the platter without touching the platter surface.
5.Lock the tone arm back into the tone arm rest.
6.While holding the counterweight steady, and without any rotation, carefully rotate only the black stylus force gauge ring (which turns independently of the counterweight) until the “0” on the gauge ring lines up with the centerline marked along the top of the rear arm.
7.Refer to the cartridge manufacturer’s specifications for recommended tracking force. Rotate the entire counter-weight counterclockwise without touching the black gauge ring, moving the counterweight forward, until the desired value on gauge ring lines up with the centerline marked on the rear arm. Refer to the specifications section for tracking force value for the cartridge that shipped with the turntable.
Setting Anti-skate
A small outward “anti-skating” force can be applied to the tone arm to compensate for the “skating” force that pulls the arm toward the center of the record. For best performance during normal turntable
use, set the anti-skate control knob [Figure 2, page 4, #26] to the same setting as the tracking force dial. Refer to the specifications section for tracking force value of the cartridge that shipped with the turntable.
In case of substantial use of back-cueing, scratching or reverse-direction operation, you may prefer to use less, or no, anti-skate compensation.
Setting Tone Arm Assembly Height
The tone arm assembly height adjustment allows for the tone arm to be positioned parallel to the record surface, when using extra-tall
cartridge bodies, thick slip mats or thick records (i.e. old 78’s). To raise or lower the tone arm assembly: First, loosen the height lock [Figure 2, page 4, #28]; then rotate the height adjust dial [Figure 2, page 4, #21] located at the base of the tone arm assembly. The scale is calibrated in millimeters (mm). When finished, tighten the height lock to secure the adjustment.
Connections
Audio
Connect the audio output cable to the appropriate input jacks on your mixer, amplifier, soundcard or other device based on the setting of the pre-amp selector switch. Firmly connect the Red RCA-type plug to the right channel input and the White RCA-type plug to the left channel input. (Note: Adapter plugs might be required to connect the turntable to computer sound cards and other devices.)
Connecting to Computers with USB Input
The USB cable (included) connects your AT-LP120-USB turntable to your computer without need for special drivers. Refer to included software guide (also available online at www.audio-technica.com) before connecting the turntable to your computer.
Connecting to Computers or Audio Devices with 3.5 mm Input
The AT-LP120-USB 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 cables – dual 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 minijack
•input powered speakers* equipped with a 3.5 mm minijack
•input a mixer* or PA system* equipped with a 3.5 mm minijack
The second included adapter cable – dual RCA to stereo 3.5 mm miniplug (female) – permits connection of the turntable output to amplified speakers* or similar devices. The 3.5 mm stereo minijack on the cable adapter accepts stereo mini-plugs.
To use either adapter cable, connect the turntable’s red and white RCAtype plugs to the cable adapter’s RCA-type jacks.
* When using either cable adapter, always set the AT-LP120-USB turntable’s Pre-amp Selector Switch to the “LINE” position. (Switch is located on the back of the turntable.)
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.
Finally, after all other connections are made, attach the included AC power cord to the turntable; note that the small connector only goes in one way. Then connect the power cord’s plug to a convenient AC outlet.

Troubleshooting
Turntable operates but emits no sound or not enough sound.
1.The stylus guard is still in place. Remove the stylus guard.
2.The tone arm is in the lift position. Lower the tone arm.
3.Mixer/amplifier (system) controls are set incorrectly: wrong input selected, tape monitor on, speakers switched off, etc. Verify proper control settings.
4.Stylus is broken or missing. Check the stylus assembly and replace if necessary.
5.The stylus assembly may not be fully seated in the cartridge body. Check the cartridge and adjust if necessary.
6.The pre-amp selector switch is set in the wrong position. Verify that it is set for proper output to match mixer/amplifier.
-No sound/very weak sound: Phono Out setting into an Aux/Line input.
-Very loud/distorted sound: Line Out setting into a Phono input.
Turntable operates but stylus “skips” across record.
1.The stylus guard is still in place. Remove the stylus guard.
2.The tracking force is set too light. Set tracking force per cartridge manufacturer’s recommendation.
3.The tracking force is set too heavy (stylus assembly is bottoming out on record). Set tracking force per cartridge manufacturer’s recommendation.
4.The anti-skate control is set improperly. Verify anti-skate is set for same value as cartridge tracking force.
5Turntable is picking up excessive vibrations from floor, walls, or nearby speakers. Reduce vibrations or place turntable on sturdy/ solid surface.
Record sounds too fast or too slow.
1.Turntable is set for wrong speed. Make proper speed selection for
record type being played with platter speed buttons.
2.Variable pitch is engaged. Depress quartz button or return pitch adjust slider to center detent position to engage quartz lock.
Moving pitch adjust slider produces no effect.
If the LED next to the pitch adjust slider center detent position remains green when the slider is moved, quartz lock is engaged. Depress the quartz button to disengage the quartz lock and activate variable pitch. The LED should turn RED.
Strobe dots are difficult to see and/or stylus illuminator is very dim.
1.Excessively bright or fluorescent light interferes with strobe indicator. Hold hand, record jacket, etc. over strobe indicator to shield it from bright light.
2.Voltage selector switch is set for 230V when AC mains are 115V. Disconnect AC power cord and reset the voltage selector switch located under the platter. (Note: Even with the voltage selector set for 230V when AC mains are 115V, the quartz lock will bring the platter up to proper speed.)
Tips For Better Performance
•When opening or closing the turntable cover, handle it gently, moving it either at the center or equally from both sides.
•Do not touch the stylus tip with your fingers; avoid bumping the stylus on the turntable mat or a record’s edge.
•Clean the stylus tip frequently, using a soft brush and a back- to-front motion.
•If you use a stylus cleaning fluid, use it sparingly.
•Wipe the dust cover and turntable housing gently with a soft cloth. Use only a small amount of mild detergent solution to clean the turntable and dust cover.
•Never apply harsh chemicals or solvents to any part of the turntable system.
•Prior to moving the turntable, always unplug it from the AC outlet and lock the tone arm on the tone arm rest.
