Bottom Panel Features
1. Adjustable Rubber Dampening Feet:
When all of the feet of the turntable are completely tightened, the top flat surface of the turntable will be at 85mm. Unscrewing these feet raises the turntable up to compensate for unleveled surfaces.
2. Carrying Handles:
These handles provide a secure grip so that the turntable may be comfortably transported.
3. Voltage Selector:
This switches the internal voltage transformer between 115V, 230V and 240V. The turntable should be shipped with the proper voltage setting for your region. Check that the switch is in the proper voltage before connecting the power cord to prevent damage to the turntable.
4. IEC Power Terminal:
This IEC Power Terminal can be used with any IEC power cable, but it is recommended that the supplied IEC power cable be used. Be sure that any IEC power cable attached has proper clearance underneath the unit not to pinch cable or break power jack.
5. RCA Output:
These stereo output jacks allow the turntable to be connected to a compatible device with a PHONO or
LINE level input.
6. Phono/Line Selector:
This switch should be set to the proper level depending on the type of input the turntable is connected to. PHONO is used with traditional turntable inputs on older receivers or where PHONO is stated. LINE level allows the TTXUSB to directly connect to modern electronic inputs such as computers, home stereos, and mixers.
7. Gain:
This knob sets the level of the audio signal going through the USB port to your computer. Please adjust the gain to a suitable level so the meters in your software application never hit the clip meter
(red).
8. USB Audio Output:
Use the included USB Cable to connect your turntable to your computer. Refer to the software instruction guide for more information.

Tonearm Assembly
1. Counterweight/Ring and S-Weight:
8. Tone Arm Lock Nut:
This aluminum nut is used to secure the head shell and cartridge assembly to the tone arm tube. See cartridge setup for more details.
The Counterweight is used to balance the head shell and cartridge assembly so that the proper amount of stylus pressure is applied to the record. The S-Weight should be used in most cases when the S-Shaped tube is used. It is not needed for the straight arm and can be stored below the counterweight in the top cabinet while not in use.
2. Height Adjust Ring:
Turning this ring counter-clockwise raises the tonearm up to 6mm to accommodate for different slipmat thicknesses. This ring can not be adjusted unless the Height Lock Lever (3) is unlocked.
3. Height Lock Lever:
Turning this lever towards the direction of the arrow (clockwise) unlocks the Height Adjust
Ring (2) so that the tonearm height can be adjusted.
4. Anti-Skate Adjustment:
This knob is used to compensate for inward tracking forces. See Tonearm Setup for more details on its settings.
5. Secondary Tube Lock Collar:
This collar is used to secure the tonearm tubes
(straight or s-shaped) to the tonearm assembly.
6. Arm Clip:
This specially designed arm clip secures the tone arm while it is being transported or not in use.
7. Tonearm Cueing System:
This feature allows the tone arm to be positioned at a certain point above the record and slowly engaged. When the lift lever is in the up position the tone arm should rest on the armrest. When the lift lever is lowered, the tone arm is slowly lowered until the stylus is resting on the record.
WARNING: DO NOT OVERTIGHTEN LOCK COLLAR (5) OR THE LOCK NUT (8)!
CONNECTING ANYTHING OTHER THAN NUMARK ARMS TO THIS COLLAR MAY DAMAGE THE
INTERNAL PIN HEIGHTS OF THE CONTACTS!

Tonearm Setup
1. Install cartridge and raise the arm lift for cartridge/stylus protection.
2. Notice how the counterweight can be moved.
3. With the cueing system lift lever down, adjust the weight so entire tonearm assembly is freely balanced.
4. Zero the scale on the weight by moving the black ring until “0” is aligned with the slot. The tonearm assembly should still be balanced as shown in Figure 2.
5. Turn the counterweight until the desired weight in grams is met. (Most DJ cartridge specifications range from 2.0g to 4.0g. Check cartridge manual for details)
Setting the Anti-Skate Adjustment
The Anti-Skate control is the knob shown on the last figure.
In most cases, the Anti-Skate should be set to its minimum setting. Anti-Skate compensates for inward tracking forces that occur with certain cartridges when the stylus nears the center of the record. If the turntable is experiencing excessive skipping during back-cueing and scratching while nearing the center spindle, try increasing the Anti-Skate in the increments indicated on the dial. Start by adding small increments; test its performance, then increase it as necessary.
The Anti-Skate control is primarily used for high quality recordings in conjunction with the tonearm cuing system.
OPERATION NOTES
This turntable was designed to accommodate a variety of different mixing styles. Here are some general operation guidelines to optimize the performance of the turntable.
• Use the included Slip Mat during record playback. This Slip Mat was designed to reduce friction between the platter and the record to allow for rapid back cueing and efficient scratch play.
• Do not place the turntable on or near a speaker or subwoofer. This may cause unwanted noise depending on the environment conditions.
• Always secure the tone arm using the Arm Clip when not in use. This can prevent stylus damage and accidental tone arm engagement.
• To reduce needle skipping, follow the guidelines in the Tone Arm Setup section of this manual. Too much weight on a cartridge may cause erratic skipping or stylus damage.

General Controls
1. Power Button: Turns on the turntable when pressed. It illuminates blue when the turntable is switched on.
2. Start/Stop Buttons: Start and stop the turntable motor. Both buttons have the same function.
3. Platter: This turntable has a special edge design that has been optimized for "dragged" platter slow downs. The pattern will appear to stand still when the Pitch Range is set to 0% and the Target Light is being used.
4. Forward/Reverse Toggle: Switches the motor direction between forward and reverse.
5. Start Time Adjuster: Rotate to increase or decrease the startup time of the platter.
6. Braking Time Adjuster: Rotate to increase or decrease the stopping time of the platter.
7. Strobe Target Light and Power Jack: This aluminum light can be rotated depending on the head shell position and the amount of light required on the vinyl record surface. The light strobes against the platter edge making the pattern appear to stand still when the Pitch Range is at 0%.
8. Pitch Fader: This slide control allows the pitch of the playback to be changed. In the center position the pitch is at 0%
9. Key Lock: This button locks the key of the music at the relative position of the Pitch Fader. This processing effect is only available when the LINE output is used.
10. Quartz Button: This button locks the pitch at 0% (regardless of pitch fader position) using Quartz
Motor Control when engaged.
11. Torque Adjustment: Lightly press buttons 9 and 10 simultaneously to adjust the torque settings of the platter. There are three settings for torque. “L” is low, “M” is medium, and “H” is high.

Display Controls
The Display of the TTXUSB was developed to instantly provide usable feedback regardless of the turntable orientation. Understanding its functions may improve your skill level.
1. Platter Direction Sensors: Whether the turntable platter is turning or stopped, these segments indicate the direction of rotation. They move in pairs on opposite sides of the display.
NOTE: If the platter is removed while the turntable is powered on, the entire ring of segments will flash indicating that the drive magnets have been pulled apart and the motor has entered PROTECTION MODE. It is recommended that the turntable be powered off after it enters PROTECTION MODE before replacing the platter.
2. Multi-Function Segment Indicators: Depending on the display mode, these Indicators may provide pitch, BPM or motor settings. See the independent functions of the PITCH, BPM and MOTOR
CONTROLS for additional information.
3. BPM Button: Pressing this button will toggle the center section of the display between the current pitch setting and an estimated beats per minute (BPM) reading. If this button is pressed and held for
2 seconds, the BPM counter will recalculate the BPM estimation. If the display is indicating a steady
"---" this means that the TTXUSB is calculating the BPM range OR it is unable to distinguish an estimate. If the BPM estimation is a flashing "---" then this indicates that there is no audio being processed.
4. Pitch versus BPM indicators: The word PITCH and the PERCENTAGE symbol are both active while the display indicates the pitch setting. The
BPM indicator is only active when the display is set to provide BPM estimations.
5. Pitch Range Button: This button toggles the pitch range between 10,
20 and 50% when pressed in succession. If this button is pressed and held for 2 seconds, the pitch range will be set to 8% until the button is pressed again. If this button is pressed and held together with the
BPM Button (3), then the contrast of the Display will be reduced until the buttons are released.
6. Pitch Range Indicators: Depending on the pitch range (8, 10, 20, 50%) these indicators will be active. When the pitch range is set to 8%, none of these indicators are active.
7. RPM settings: The 33, 45 or 78 segments will be active for the respective motor RPM mode.
8. Key Lock Indicator: This symbol indicates that the onboard digital signal processors are correcting the KEY of the playback source.
NOTE: The KEY LOCK function can only be used while the output is set to LINE level.
9. Quartz Lock Indication: If the QUARTZ LOCK function (General Controls) is engaged, this segment becomes active and the display will flash "- Q -" if the PITCH FADER is adjusted until the
QUARTZ LOCK function is deactivated.
10. Start Time Indicator: If this indicator is active while the motor is starting, it means that the startup time has been adjusted using the Start Time Adjuster (General Controls)
11. Brake Time Indicator: If this indicator is active while the motor is stopping, it means that the stop time has been adjusted using the Braking Time Adjuster (General Controls)
12. Contrast: Press both (3) and (5) simultaneously to cycle through contrast levels on the display.

OTHER IMPORTANT NOTES
•
•
Please read these precautionary notes to insure a complete understanding and long life of this DJ turntable.
• Unnecessarily removing the platter may cause damage to the magnet mounting structure, the motor or the platter resulting in undesired performance. The turntable should ALWAYS be powered off before the turntable platter is removed for any reason.
• Unnecessarily "interchanging" tonearm tubes may cause premature wear to components of the tonearm assembly or the tonearm tubes. Interchange tubes only on an "as needed" basis.
• Turning off the turntable while the output is set to LINE level or while the SPDIF output is in use will result in an absence of audio. Keep this in mind during use - if the "motor off" effect is desired effect, it is recommended that the BRAKE MOTOR CONTROL be adjusted.
• Do not attempt to adjust or tighten any tonearm components. Undesirable performance may be a result of an improperly adjusted tonearm or worn cartridge.
Never interchange tonearm tubes while the turntable is powered on.
Any attempt to "customize" your turntable beyond interchanging the tonearm tubes is not recommended and may result in PERMANENT DAMAGE to the turntable and/or a VOIDED
WARRANTY.
