Audio mono jack 6.3 mm male VivoLink PROAUDJACKMRCA3 — 6.3mm mono connector, metal housing

VivoLink PROAUDJACKMRCA3 is a 6.3 mm (1/4") mono male audio jack designed for connecting instruments, amplifiers and audio equipment that use a mono phone jack. The connector uses a standard 6.3 mm tip for single-channel audio and is built with a metal housing to provide solid mechanical strength and consistent signal transfer in stage, studio and home applications.

Advantages

The metal housing increases durability and resistance to wear from repeated insertions and movement. A standard 6.3 mm mono tip ensures compatibility with common instrument cables, amplifiers and mixing consoles that accept mono phone plugs. The simple, single-channel design reduces wiring complexity and provides a reliable, low-loss connection for unbalanced audio signals.

Suitable for

• Connecting electric guitars, basses and other instruments to amplifiers
• Patching mono outputs to mixers and effect units
• Stage and live sound setups requiring robust mechanical connectors
• Home studio and rehearsal rigs where mono connections are used

Key specifications

• Connector type: 6.3 mm (1/4") mono male (phone plug)
• Housing material: metal for enhanced mechanical strength
• Contact plating: standard audio-grade plating for reliable contact (non-specified)
• Signal type: unbalanced mono audio
• Typical use: instruments, amplifiers, audio equipment with mono jack

How to use

Insert the 6.3 mm mono plug fully into the matching mono jack on the instrument, amplifier or audio device until it seats securely. Ensure the cable and connector orientation match the device input to avoid partial contact. If the connector is used in an environment with frequent movement, check the metal housing and mating jack periodically for signs of wear or loosening and reseat as needed. For solder or assembly applications, follow the cable manufacturer's instructions for secure mechanical and electrical connection to the plug.

Recommendations

Use this 6.3 mm mono plug where a single-channel, unbalanced connection is required. Avoid using mono plugs for stereo signals, and keep connectors clean and free of corrosion by storing equipment in dry conditions. For longer cable runs or environments with high interference, consider balanced connections or DI boxes to preserve signal integrity.
