Setup
- Unpack: Carefully remove all components from the packaging.
- Placement: Position the turntable on a flat, stable surface. Ensure adequate ventilation and avoid placing it near speakers to prevent feedback.

- Belt Installation: Locate the drive belt and carefully stretch it around the inner rim of the platter and over the motor pulley.
- Slipmat: Place the slipmat on the platter.
- Counterweight: Attach the counterweight to the rear of the tonearm. Adjust it to balance the tonearm horizontally. Refer to the cartridge manufacturer's recommendations for the correct tracking force.
- Power Connection: Connect the power cord to the turntable and then to a suitable AC power outlet.
- Audio Connection: Connect the RCA audio output cables (not included) from the turntable to the PHONO input of your amplifier or receiver. If your amplifier does not have a PHONO input, you may need an external phono preamplifier.
- USB Connection (Optional): Connect the supplied USB cable from the turntable to an available USB port on your computer for digital recording.
Operating Instructions
- Power On: Ensure the turntable is connected to power.
- Select Speed: Choose the appropriate speed (33 1/3 or 45 RPM) for your record using the speed selector buttons. For 45 RPM records, place the 45 RPM adapter on the spindle if the record has a large center hole.
- Place Record: Carefully place your vinyl record on the slipmat.
- Start Platter: Press the START/STOP button to begin platter rotation.
- Position Tonearm: Gently lift the tonearm using the cueing lever and move it over the desired track on the record.
- Lower Tonearm: Slowly lower the tonearm onto the record using the cueing lever. The stylus will begin playing the record.
- Adjust Pitch: Use the PITCH slider to fine-tune the playback speed if necessary.
- Stop Playback: At the end of the record, or when you wish to stop, lift the tonearm using the cueing lever and return it to the tonearm rest. Press the START/STOP button to halt platter rotation.
- USB Recording: When connected to a computer via USB, the turntable acts as an audio input device. Use appropriate recording software (not included) on your computer to capture the audio from your records.
Maintenance
- Cleaning the Stylus: Use a soft brush designed for stylus cleaning, brushing gently from back to front.
