Setup and Connection

Follow these steps to properly connect your Nakamichi speaker cables to your audio equipment.

1. Identify Polarity: Observe the color-coded banana plugs and cable markings. Red typically indicates positive (+), and black/white indicates negative (-). Ensure consistent polarity from your amplifier/receiver to your speakers.
2. Connect to Amplifier/Receiver: Insert the banana plugs into the corresponding binding posts on your A/V receiver or amplifier. Push firmly until the plug is fully seated.
3. Connect to Speakers: Insert the other end of the banana plugs into the corresponding binding posts on your speakers. Ensure a snug fit.
4. Secure Connection: The banana plugs are designed for a secure fit. If you are using raw wire ends (not applicable for this pre-terminated cable), ensure the set screws are tightened to hold the wire firmly.

Maintenance

To ensure the longevity and optimal performance of your speaker cables:

• Keep cables clean and free from dust. Use a soft, dry cloth for cleaning.
• Avoid sharp bends or kinks in the cable, as this can damage the internal conductors.
• Periodically check connections to ensure they remain secure.
• Store cables in a cool, dry place when not in use.

Troubleshooting

If you experience issues with your audio system, consider the following:

• No Sound:
  • Check all cable connections at both the amplifier/receiver and speakers to ensure they are fully inserted and secure.
  • Verify that the correct input source is selected on your amplifier/receiver.
  • Confirm that the amplifier/receiver and speakers are powered on and volume is not muted or set too low.
• Poor Sound Quality (e.g., static, distortion):
  • Ensure consistent polarity (+ to + and - to -) for all speaker connections. Incorrect polarity can lead to phase issues and degraded sound.
  • Check for any damage to the cable jacket or banana plugs.
  • Ensure cables are not running near sources of electromagnetic interference (EMI).
