3. Tone Arm and Cartridge Setup
The turntable features a fully adjustable S-shaped tone arm assembly. Install your chosen cartridge onto the headshell, then attach the headshell to the tone arm.

4. Connecting to Audio System and Computer

Ensure the ground wire is connected to your amplifier's ground terminal to minimize hum.
- USB Output: For digital conversion, connect the USB cable from the turntable to your computer. Install the included Audacity software to record and convert your vinyl collection to digital file formats.
- Power: Connect the power cable to the turntable and a suitable AC outlet (120 Volts).
