C2G CG40639 6.3mm to 3.5mm Stereo Audio Adapter

Product Description

The C2G CG40639 is a 6.3mm stereo male to 3.5mm stereo female audio adapter designed to bridge the gap between full-size quarter-inch audio connections and standard 3.5mm mini-stereo jacks. This compact adapter allows technicians and installers to connect equipment with standard quarter-inch stereo outputs to devices that accept 3.5mm stereo inputs. It is a passive, inline adapter requiring no external power. Audio and AV professionals, electricians, and low-voltage installers commonly use this type of adapter during system integration, equipment setup, or troubleshooting tasks where connector format mismatches occur.

This adapter is suited for use in residential and light commercial audio-visual installations where a 6.3mm stereo source needs to interface with a 3.5mm stereo input. Typical applications include connecting musical instruments, mixers, or professional audio equipment to consumer-grade devices, laptops, or recording interfaces. It is sold as a single unit and is appropriate for any scenario requiring a quick, tool-free conversion between these two common audio connector formats.

• Converts 6.3mm quarter-inch stereo male to 3.5mm stereo female in a single inline adapter

Compatibility

Designed as an inline passive adapter suitable for standard 6.3mm stereo male and 3.5mm stereo female audio connections across a wide range of consumer and professional audio equipment.

Installation Notes

This adapter requires no tools or wiring and installs by hand. Ensure both mating connectors are fully seated before signal testing. Low-voltage audio installers should verify that the source and destination equipment are both stereo-configured to avoid signal loss or channel mismatch. Power down or mute active amplification equipment before connecting or disconnecting audio adapters to prevent transient noise.
