Description
The C2G’s audio adapter CG40639 is designed to help convert a 3.5mm stereo plug to a 6.3mm (1/4 inch) stereo plug. In many AV and conference room setups, instances may arise when two pieces of equipment simply do not match up in terms of their connectors. It is exactly in these instances that this adapter is designed for use with audio equipment featuring a 6.3mm stereo input. The CG40639 adapters allow equipment with this configuration to connect with devices via a 3.5mm stereo output, such as headphones or auxiliary cables. Additionally, as a TAA-compliant adapter, it can be used in government and institutional settings.
The C2G CG40639 is a practical option that provides a compact solution to audio device compatibility problems. As a 6.3mm stereo male to 3.5mm stereo female adapter, it performs a very specific and often necessary task of bridging the connection gap between commonly used professional-grade audio gear.
This small adapter connects a standard 3.5mm stereo plug, often found on laptops, tablets, and mobile devices, and enables them to be connected to audio equipment with a 6.3 mm or 1/4-inch stereo input. In professional environments, like conference rooms, training spaces, or live sound setups, this means being able to plug the audio output of a laptop directly into a mixing board or amplifier that accepts 1/4-inch stereo plugs. It eliminates the need for extra connecting cables or converters and helps set up an instant connection between devices while keeping the space tidy and the connection straightforward.
The CG40639 is engineered for durability in repeated-use environments. The adapter is built with molded strain relief and nickel-plated contacts. It can handle frequent plugging and unplugging, which is a common vice in shared equipment spaces.
The CG40639 adapter is also TAA-compliant. It meets standards for safe use in government and public sector installations. This makes it a reliable choice to use in environments where regulatory compliance is a strict part of the purchasing criteria. So, be it for professional offices, federal buildings, public universities, or other institutions with similar standards, the CG40639 can be used for any AV setup.
Whenever a presenter takes part in a presentation on their device, but the installed sound system has 1/4-inch audio inputs. Having this adapter on hand, there is no need to scramble for a workaround. Just plug in and proceed with the meeting.
