1. Support Feet: If you want to (slightly) lower or raise the height of your TT250USB, you can
turn the four support feet clockwise or counterclockwise, respectively.

2. RCA Audio Output Cables: Connect these attached cables to the audio inputs of your
mixer, stereo system, etc. Their output signal is line-level, so connect it only to line-level
inputs, not phono-level.

Please note: You can still copy records to your computer (via the USB port) even if these
cables are not connected to a stereo system. You can also listen to your records through
your computer as long as you have configured your computer’s sound input and output
options correctly.

Warning: You may damage your receiver if you plug in line-level output into a phono-level input.

3. Power Cable: Connect this attached power cable to a power outlet after making all of
your other audio connections.

4. Remote Start Input: Use connect a 1/8” (3.5 mm) cable to connect this input to the
remote start output of a compatible mixer. While connected, TT250USB’s platter will start
rotating when the mixer’s crossfader moves towards that side.

5. USB Port: Use the included USB cable to connect this USB port to your computer. You
can listen to your records through your computer as long as you have configured your
computer’s sound input and output options correctly.

6. Power Switch: Press this switch to power TT250USB on or off. The ring around the switch
illuminates when TT250USB is powered on.

7. Voltage Selector (under platter): Use the switch under the platter to select the voltage for
your country. Change this setting only when necessary (e.g., when traveling to a country or
region with a different voltage). Selecting an improper voltage setting can damage the unit.

8. Platter: This platter must be properly placed to the turntable motor prior to operation. See

Setup > Platter for detailed information on securing the platter.

9. 45 RPM Adapter: Store your 45 RPM adapter here.

10. 33 and 45 RPM Buttons: Press either of these buttons to set the rotation speed (RPM) of
the platter. A light above the button indicates the current selection.

11. Strobe Light: This light illuminates the edge of the platter, which indicates its current speed
(RPM). While the platter rotates at each speed, one of the rows of circles on its edge will
appear to remain still under the light’s strobing. The first and second rows correspond to 33
and 45 RPM (respectively) when the voltage selector is set to 230 V (50 Hz). The third and
fourth rows correspond to 33 and 45 RPM (respectively) when the voltage selector is set to
115 V (60 Hz).

12. Start/Stop: This button starts and stops the turntable motor. If it seems not to be
functioning, check to make sure that the platter is properly secured (see Setup > Platter).

13. Target Light: This light illuminates the platter so you can view the label on your record. To
turn it on, press the smaller button next to it. To turn it off, push the light downward into
the base until it locks in place.

14. Pitch Light: This light illuminates when the pitch slider is set at 0%.

15. Pitch Fader: Move this fader to increase or decrease the pitch of the track (and speed of
the platter) by up to 10%. In the center position, the pitch is at 0%.

16. Pitch-Bend –/+: Press either of these buttons to temporarily reduce or increase the pitch
of the track (speed of the platter). If the pitch fader is already at its lowest or highest
position, you cannot use the corresponding pitch-bend button to bend the pitch further in
that direction.

17. Cartridge Holder: Use this space to store your cartridge while transporting TT250USB.

Tonearm

Refer to Setup > Tonearm for additional details on these controls.

18. Counterweight and Scale Ring: The counterweight
balances the cartridge and headshell assembly so the
tonearm can apply the proper amount of stylus pressure
to the record.

19. Anti-Skate Dial: Use this dial to compensate for inward
tracking forces that occur with certain cartridges when
the stylus nears the center of the record. In most cases,
set this to 0. If you experience excessive skipping during
back-cueing or scratching while nearing the center of the
record, increase this dial’s setting in small increments and
test its performance.

20. Height Adjust: Use this lever to set the height of the
tonearm. Move the small Lock lever (above the Anti­Skate Dial) counterclockwise or clockwise to unlock or
lock the height adjustment, respectively. See Setup >

Tonearm for more details.

21. Tonearm Lever: Lift this lever up or down to raise or lower
the tonearm. Raise the tonearm before moving it toward or
away from the record, and lower it once it is in place.

22. Arm Clip: Close this clip to secure the tonearm while it is
not being used. The clip remains in the “up” position while
open.

Note: To prevent damage while transporting TT250USB,
we recommend removing the cartridge and headshell
assembly as well as securing tonearm in the arm clip.

23. Tonearm Lock Nut: This nut secures the headshell and
cartridge assembly to the tonearm. Turn the cartridge
clockwise to loosen it or counterclockwise to tighten it,
but do not over-tighten it.

24. Cartridge and Headshell: The included cartridge is pre­mounted on a standard headshell. Remove the plastic
cartridge cover (needle cover) before using TT250USB.
This is user-replaceable and compatible with a variety of
standard cartridges.

Setup

Platter

Place the platter onto the motor by aligning the pins in the bottom of
the platter with the holes in the motor. Press it down firmly. Check to
make sure that it rotates uniformly and does not wobble excessively,
and then place the slipmat onto the platter.

Important:

• Incorrect platter setup can lead to poor turntable performance,
platter instability or permanent motor damage.

• Make sure that the felt slipmat is always placed on top of the
platter while using the turntable. Failure to use the slipmat may
cause damage to your media as well as damage to the turntable.

0 360° 1

4 g

Important: Refer to the documentation for your cartridge to determine the proper stylus

pressure/weight (in grams) and tonearm height (in millimeters).

1. Make sure the cartridge is on the tonearm. Turn it clockwise to loosen it or
counterclockwise to tighten it. Do not over-tighten it! Remove the plastic cartridge cover
(needle cover) before operating the turntable.

2. Rotate the counterweight counterclockwise (while you are facing the scale ring) until it is
in the complete forward position.

Note: This is also the maximum amount of pressure that can be applied to the cartridge.

3. Now there should be a feeling of weight and resistance when the headshell is raised and
lowered. Begin rotating the counterweight clockwise (while you are facing the scale ring)
until the weight and resistance feeling is gone. If done properly, the tonearm will pivot with
very little resistance back and forth indicating that there is exactly 0 grams of stylus pressure.

4. With the counterweight in its new position further away from tonearm pivot point, grasp
the scale ring only and rotate it until 0 is in the vertical position.

5. Finally, rotate the counterweight (and scale ring) counterclockwise until you reach the
desired weight. A complete revolution of the scale ring corresponds to 3 g, so if the scale
rotates 360° beyond the 0 point, add 3 to the new scale ring reading.

Note: The included headshell and cartridge assembly requires a minimum of 3 grams and
no more than 5 grams for optimum performance.

6. Push the small Lock lever (above the Anti-Skate Dial) counterclockwise to unlock the
height adjustment. Place the stylus on your record, and then move the Height Adjust lever
to raise or lower the tonearm so it is parallel with the record. Push the Lock lever
clockwise to lock the new height adjustment.
