Initial Setup
Assembling the Turntable
The AT-LP240-USB requires some assembly before first use.
IMPORTANT: Do not connect the AC power cord until assembly is
complete.
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
panel of the turntable [See Figure 2, page 4, #22], selects the internal
stereo pre-amplifier (LINE), or bypasses the pre-amp (PHONO) for use
with systems having specialized magnetic phono input jacks. The audio
output cable’s Red RCA 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 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 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 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: A standard stereo cartridge headshell is supplied with the
AT-LP240-USB. To mount your cartridge (not included) to the headshell,
follow instructions included with your cartridge.
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 1, page 3, #15.]
2. Mount your cartridge (not included) to the supplied headshell,
follow instructions included with your cartridge.
3. Attach the headshell assembly by inserting it into the socket at
the front of the tone arm [See Figure 3.] (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.)
4. 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.)

5. 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 1, page 3, #19]; the counterweight will engage
the spiral groove in the rear arm section and move forward.

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 4.]
2. Place the soft black slip mat on top of the platter.

The Dust Cover
The dust cover sits on top of the turntable without a hinge. It is not
intended to be used while playing records.
To place the dust cover on the turntable, carefully lower it onto the
turntable so that the Audio-Technica logo is facing the front of the unit.
To remove the dust cover from the turntable, carefully lift straight up
until the cover is clear of the unit.
24. AC POWER CORD CONNECTOR
Use to connect the included power cord.
