How to use

• The product is extremely delicate. Handle it with sufficient care.
• This product can be mounted only on a through-hole type headshell or headshell-integrated tonearm.

1. Mount the product onto the headshell or headshell-integrated tonearm.
   • Mount the cartridge with the protector on to avoid damaging the cantilever and the stylus tip.
   • Temporarily tighten the screws.

2. Connect the lead tips, noting output polarity.
   • Connect headshell lead tips to the product output terminals (as shown in the figure).
   • Never apply heat (from solder, etc.) to the output terminals.

3. Remove the protector from the product.

4. Determine the correct position for installing the product (adjust overhang).
   • Adjust overhang following the instructions in the tonearm’s, turntable’s, or headshell’s user manual.
   If you are unsure, align the stylus tip to the cartridge originally attached to the tonearm (as shown in the figure).
   • Finish tightening screws, making sure there is a balance between left and right.

5. Adjust tracking force.
   • Confirm the tracking force for the product in “Specifications.”
   • Do not apply stylus pressure unnecessarily. It may not only damage the record and stylus but impair audio quality.

6. Adjust tonearm height.
   • Adjust the height so that the bottom surface of the headshell and the record surface are parallel, as seen from the side. An improper tonearm height may cause the body of the product to make contact with the record and could impair audio quality or damage the record.

• You need a transformer, head amplifier, or standalone phono equalizer to connect to a preamplifier/amplifier. If the preamplifier/amplifier has a phono input (MC position), it may be used as it is. However, to fully take advantage of this product’s audio quality, using a step-up transformer (sold separately), head amplifier (sold separately), or phono equalizer (sold separately) is recommended. For connection instructions, refer to the user manual of the equipment you are connecting.

Care

• Use the brush provided to remove dirt and dust on the stylus tip.
• Always move the brush in the direction in which the record rotates.
• A stylus cleaner (sold separately) is recommended to remove stubborn dirt.
• When the product is removed from the tonearm, do not forget to attach the protector and store the product away from the amplifier and other heat sources and magnetic materials.
