Setup and Installation
Proper installation of banana plugs ensures a secure connection and optimal audio performance. Follow these steps carefully:
Required Tools:
- Wire Strippers
- Small Flathead Screwdriver (for set screws)
Installation Steps:
- Prepare the Banana Plug:
Unscrew the outer sleeve of the banana plug by turning it counter-clockwise. This will expose the inner gold-plated connector with two set screws.

- Loosen Set Screws:
Using a small flathead screwdriver, slightly loosen both set screws on the inner connector. Do not remove them completely.
- Prepare Speaker Wire:
Strip approximately 14mm (0.55 inches) of insulation from the end of your speaker wire. Twist the exposed copper strands tightly to prevent fraying.
- Insert Speaker Wire:
Carefully insert the stripped end of the speaker wire into the opening at the rear of the inner banana plug connector, ensuring all strands are inside.
- Secure the Wire:
Tighten both set screws firmly onto the speaker wire using the flathead screwdriver. Ensure the wire is securely held and cannot be easily pulled out.
- Reattach Outer Sleeve:
Screw the outer sleeve back onto the inner connector by turning it clockwise until it is snug. This encloses the wire connection, preventing short circuits.
- Connect to Audio Equipment:
Insert the assembled banana plug into the corresponding banana jack on your amplifier, receiver, or speaker. Ensure correct polarity (red for positive, black for negative).

Ensure all connections are firm before powering on your audio equipment. The color-coded collars (red for positive, black for negative) assist in maintaining correct polarity throughout your setup.
Maintenance
FosPower banana plugs are designed for durability and minimal maintenance. The 24K gold plating resists corrosion, ensuring long-lasting performance.
- Periodic Check: Occasionally check the tightness of the set screws and the connection to your audio equipment to ensure they remain secure.
- Cleaning: If necessary, gently wipe the plugs with a dry, soft cloth to remove dust or debris. Avoid using harsh chemicals or abrasive materials.
- Storage: When not in use, store the plugs in a dry environment to prevent any potential damage.
Troubleshooting
If you encounter issues with your audio connections, consider the following:
- No Sound or Intermittent Audio:
- Verify that the speaker wire is securely tightened by the set screws within the banana plug.
- Ensure the banana plug is fully inserted into the audio equipment's jack.
- Check for correct polarity (red to red, black to black) at both the speaker and the amplifier/receiver.
- Inspect the speaker wire for any damage or breaks in the insulation.
- Poor Sound Quality:
- Confirm that the stripped wire length is appropriate (approx. 14mm) and that no stray strands are causing a short circuit.
- Ensure the set screws are tight enough to make good contact with all wire strands.
