Speaker binding post Karlik MGGBO-4 single banana-type terminals, gold-plated, red and black, screw, 4 mm²

Single speaker binding post Karlik MGGBO-4 banana-type terminal with gold-plated contacts and screw termination. Designed for reliable speaker cable connection in amplifiers, receivers and loudspeakers, this single terminal accepts banana plugs and bare or ferruled conductors up to 4 mm². The pair of terminals in red and black provides clear polarity marking for installation panels, custom enclosures and retrofit projects where low-resistance, corrosion-resistant contacts are required.

Advantages

Gold-plated contact surfaces reduce oxidation and ensure consistent low-resistance signal transfer. The banana-type terminal supports quick connection and disconnection while the screw clamp secures bare or ferruled cables up to 4 mm². Color-coded red and black housings simplify correct polarity identification during installation. The compact design is suitable for panel mounting and tight enclosures, providing a durable mechanical and electrical connection for audio applications.

Suitable for

• Speaker terminals on amplifiers and receivers
• Custom loudspeaker cabinets and studio monitors
• Wall plates and installation panels
• Retrofit and DIY audio projects requiring secure, low-resistance connections

Key specifications

• Terminal type: single banana-type binding post with screw clamp
• Contact finish: gold-plated contacts for improved corrosion resistance
• Connection options: banana plug insertion and screw clamping for bare or ferruled wires
• Maximum conductor size: suitable for conductors up to 4 mm²
• Polarity indication: color-coded red and black housings
• Mounting: panel-mounted design for installation panels and enclosures

How to use

Mount the binding post into the panel or enclosure cutout and secure it according to the product's threaded mounting design. For banana plug connections, insert the plug into the banana socket until it seats firmly. For bare or ferruled conductors, loosen the screw clamp, insert the conductor into the terminal barrel and tighten the screw to achieve a stable mechanical and electrical connection. Verify correct polarity by matching red to positive and black to negative before powering the system.

Usage recommendations

Use appropriately sized ferrules or tinned ends for stranded speaker cable to improve contact reliability and prevent stray strands. Tighten the screw clamp to a firm but not excessive torque to avoid damage to the conductor or terminal. For fixed installations, use panel seals or insulating washers as needed to maintain safe spacing and prevent short circuits.
