The GBC 30.5643.00 is a one-piece adapter that bridges a 3-pole XLR female socket (Connection A) to a 6.3 mm stereo male plug (Connection B). It is built from nickel-plated brass in both the housing and the contacts, providing reliable conductivity and corrosion resistance in a passive, no-frills form factor.

This adapter is useful for connecting microphones or XLR-output devices to mixing desks, amplifiers, or recording interfaces that accept a 6.3 mm stereo jack.
