5PCS 4MM Banana Connectors — solderless, stackable, pinstyle plugs in Red, Black, Blue, Grey. Designed for quick, reliable audio and video cable connections without soldering. Ideal for speaker systems, musical equipment, and DIY wiring where fast installation and clear polarity identification matter. Key benefits Quick, solder installation: connect stripped cable directly to the connector for fast setup and changes. Stackable design: allows another banana plug to be inserted on for daisychaining or parallel connections without extra adapters. Clear color coding: Red, Black, Blue, Grey options help keep channels and polarity organized during installation and troubleshooting. Compact 4 mm size: fits standard 4 mm banana sockets commonly used on speakers, amplifiers, and test equipment. Reliable signal path: pinstyle banana connectors provide a stable mechanical and electrical connection for audio and video applications. Main features Quantity: 5 pieces per set Connector type: 4 mm banana, pinstyle Installation: solderless (no soldering required) Functionality: stackable for chaining or spacesaving setups Colors: Red, Black, Blue, Grey Typical uses: speaker wiring, audio/video connections, musical instrument and amplifier hookups Compatibility and performance Compatible with standard 4 mm banana jacks and sockets found on speakers, receivers, amplifiers, mixers, and test equipment. Suitable for speaker wire and general audio/video cable applications where a secure, reusable connection is needed. Color coding simplifies multichannel systems and reduces wiring mistakes during setup or maintenance. Use cases 1) Home audio setup: connect bookshelf or floor speakers to an amplifier quickly, using red and black connectors for left/right polarity and blue/grey for additional channels or biamped configurations. 2) Musical gear and rehearsal: swap speaker cables between amps and speaker cabinets on the fly without soldering, and stack connectors when bridging outputs or sharing signals. 3) DIY and testing: wire prototypes, benchtest audio circuits, or create temporary connections in a studio or workshop with easy, repeatable installation. Installation tip Strip a small length of insulation from the cable, insert the conductor into the solderless banana connector, and secure according to the connector's design. Use colorcoded connectors to maintain consistent channel and polarity identification. These 5PCS 4MM banana connectors provide a practical, nofuss solution for reliable audio and video wiring where speed, clarity, and flexibility are required.
