2. What's in the Box
Upon unboxing your Ortofon 2M Red cartridge, please ensure all components are present:
- Ortofon 2M Red phono cartridge
- Mounting screws (various lengths)
- Stylus guard
- Small screwdriver (for mounting)
- Stylus brush
3. Setup and Installation
Proper installation is crucial for optimal performance. Handle the cartridge with care, avoiding contact with the stylus.
3.1. Mounting the Cartridge
- Carefully attach the cartridge to your turntable's headshell using the provided screws. Ensure the cartridge is securely fastened but do not overtighten.
- Connect the four color-coded wires from the tonearm to the corresponding pins on the cartridge. Typically:
- Red: Right channel signal (R+)
- Green: Right channel ground (RG)
- White: Left channel signal (L+)
- Blue: Left channel ground (LG)

3.2. Cartridge Alignment
Accurate alignment minimizes tracking errors and stylus wear. Use an alignment protractor (often included with your turntable or available separately) to ensure the stylus is correctly positioned in the record groove. Follow the specific instructions provided with your protractor.

3.3. Setting Tracking Force
The recommended tracking force for the Ortofon 2M Red is 1.8 grams (18 mN). Refer to your turntable's manual for instructions on balancing the tonearm and setting the tracking force accurately. Incorrect tracking force can lead to poor sound quality and accelerated stylus wear.
3.4. Setting Anti-Skating
Set the anti-skating force to match the tracking force (1.8 grams). This helps prevent the tonearm from being pulled towards the center or outside of the record, ensuring even wear on the stylus and balanced channel output.
4. Operating Instructions
Once installed and properly adjusted, your Ortofon 2M Red cartridge is ready for use.
- Ensure your turntable is connected to a phono preamplifier or an amplifier with a dedicated phono input.
- Place a clean record on the platter.
- Gently lower the tonearm onto the record's lead-in groove using the cueing lever. Avoid dropping the tonearm directly onto the record.
- After playback, use the cueing lever to lift the tonearm and return it to its rest. Always engage the stylus guard when the turntable is not in use.

5. Maintenance
Regular maintenance ensures the longevity and performance of your cartridge.
5.1. Stylus Cleaning
Clean the stylus regularly using the provided stylus brush. Brush gently from back to front (from the pivot point towards the stylus tip). Do not brush from side to side or front to back, as this can damage the cantilever.

5.2. Stylus Replacement
The stylus is a consumable part and will wear out over time, typically after 500-1000 hours of playback, depending on record condition and cleaning habits. A worn stylus can damage your records and degrade sound quality. The 2M Red stylus is user-replaceable. Replacement styli (e.g., Ortofon Stylus 2M Red or an upgrade like Stylus 2M Blue) can be purchased separately. To replace, gently pull the old stylus assembly forward and off the cartridge body, then carefully push the new stylus assembly onto the body until it clicks into place.
5.3. Cartridge Body Cleaning
Wipe the cartridge body with a soft, dry, lint-free cloth. Avoid using cleaning fluids on the cartridge body or stylus, unless specifically designed for phono cartridges.
6. Troubleshooting
If you encounter issues, review the following common problems and solutions:
- No Sound or Low Volume:
- Check all cable connections from the cartridge to the amplifier.
- Ensure your amplifier is set to the correct phono input.
- Verify the phono preamplifier is powered on (if external).
- Distorted Sound:
- Re-check tracking force and anti-skating settings.
- Verify cartridge alignment.
- Clean the stylus.
- Inspect the stylus for wear or damage. A worn stylus requires replacement.
- Humming or Buzzing Noise:
- Ensure the turntable's ground wire is properly connected to your amplifier's ground terminal.
- Move the turntable away from other electronic devices that may cause interference.
- Check for loose connections in the tonearm wiring or cartridge pins.
- Skipping or Jumping:
- Check tracking force; it might be too low.
- Ensure the record is clean and free of debris.
- Verify the turntable is level.
