FAQs

What is the advantage of a right-angle banana plug?

Right-angle banana plugs allow you to connect speaker wires at a 90-degree angle to your audio components. This is particularly useful in tight spaces, such as behind entertainment centers or in wall installations, as it creates a cleaner, more compact setup and reduces strain on the wires.

Why are these plugs gold-plated?

Gold plating provides excellent conductivity and resistance to corrosion and tarnishing. The Nakamichi Excel Series uses direct gold plating on a pure copper core, ensuring a clean signal path and long-term durability without the degradation often caused by oxidation.

What size speaker wire can these plugs accommodate?

These plugs are designed to work with speaker wires ranging from 12 AWG to 18 AWG.

How do I ensure the plug stays securely attached to the speaker wire?

The plugs feature a dual 2-set screw design. You can tighten both screws into the bare speaker wire for maximum electrical contact, or use one screw on the bare wire and the other on the wire's insulation jacket for added mechanical strength and strain relief.

Does the dull gold color mean they are not real gold?

No, the dull appearance is characteristic of direct gold plating over copper, without a shiny nickel underlayer. This direct plating method is chosen for its superior conductivity and resistance to tarnishing, ensuring pristine audio quality.

How do I connect the speaker wire to the plug?

First, strip about half an inch of insulation from the speaker wire. Then, loosen the set screws on the plug, insert the bare wire into the terminal, and tighten the set screws firmly to secure the wire.

Are these plugs compatible with all audio receivers?

They are compatible with any audio receiver or amplifier that has standard binding posts designed to accept 4mm banana plugs.

Troubleshooting

Plug does not fit binding post securely.

Verify that your audio component has standard 4mm binding posts. Ensure the speaker wire is properly inserted and the set screws are tightened firmly. If using larger gauge wire (closer to 12 AWG), ensure the wire is centered within the terminal before tightening.

Audio sounds distorted or intermittent.

Check that the speaker wire polarity is correct (color-coded sleeves match positive/negative terminals). Ensure the set screws are tight and making good contact with the speaker wire. Re-strip and re-insert the wire if necessary.

Plugs appear tarnished or discolored.

The Nakamichi Excel Series uses direct gold plating on copper, which may have a duller appearance than nickel-plated connectors. This finish is intentional to prevent tarnish and corrosion. If significant discoloration occurs, it may indicate an issue with the plating or environmental factors; contact support.

Difficulty inserting wire into the plug.

Ensure the speaker wire is not frayed and that the insulation is stripped cleanly. For thicker wires (closer to 12 AWG), ensure the strands are evenly distributed within the terminal opening before tightening the set screws.

Pros and Cons

Pros

  • Facilitates easy installation in tight spaces due to the right-angle design.
  • Durable and corrosion-resistant connectors thanks to direct 24k gold plating.
  • Optimized sound quality from the pure copper core.
  • Prevents incorrect wiring with clear color-coding for polarity.
  • Secure wire connection guaranteed by the dual set-screw mechanism.

Cons

  • Requires careful attention to speaker wire gauge (12-18 AWG) for proper fit.
  • May not be suitable for exceptionally large gauge speaker wires.
  • The dull gold finish might not appeal to users preferring a shiny aesthetic.
  • Requires basic tool (screwdriver) for installation.

Setup, Compatibility & Care

Setup:

  1. Strip approximately 1/2 inch of insulation from the end of your speaker wire.
  2. Separate the strands of the bare wire.
  3. Loosen the two set screws on the Nakamichi plug. Ensure the color-coded sleeve is on the correct polarity wire (typically red for positive, black for negative).
  4. Insert the bare speaker wire into the plug's terminal opening, ensuring good contact.
  5. Tighten both set screws firmly. For a stronger grip, you can secure one set screw into the bare wire and the other into the PVC jacket of the speaker wire.
  6. Plug the connector into your audio component's binding post.

Compatibility:

  • Speaker Wire Gauge: Compatible with speaker wires ranging from 12 AWG to 18 AWG.
  • Binding Post Size: Designed to fit standard 4mm banana plug binding posts.

Care:

  • Clean the exterior of the plugs with a soft, dry cloth as needed.
  • Avoid using abrasive cleaners or solvents, which could damage the gold plating or insulation.
  • Ensure connections remain secure to prevent dust accumulation within the plug or binding post.
