SSQ audio jack adapter 6.3 mm to 3.5 mm stereo jack, model SS-2070 is a passive adapter designed to convert a 6.3 mm (1/4") stereo plug to a 3.5 mm (1/8") stereo socket. The adapter allows headphones, instrument leads or consumer audio cables with different plug sizes to be connected without changing left/right channels. Constructed from metal and plastic, it provides a compact, portable solution for use with instruments, mixers, audio interfaces and portable audio players.

Advantages

Its small form factor makes it easy to carry and store while metal contact surfaces provide reliable signal transfer. The plastic housing reduces weight and protects connections from mechanical wear during regular use.

• Connecting headphones with 3.5 mm plugs to amplifiers or mixers with 6.3 mm jacks
• Adapting instrument or microphone cables for consumer audio devices
• Using studio headphones with portable audio players, laptops or smartphones via an intermediate cable

How to use

Insert the 6.3 mm male end of the adapter into the 6.3 mm jack of the amplifier, mixer or instrument. Plug the 3.5 mm stereo connector of your headphones or cable into the adapter's 3.5 mm female socket until it clicks into place. Ensure connections are fully seated to avoid intermittent contact. Remove the adapter by gently pulling the plug straight out to prevent stress on connectors.

Usage recommendations

To maintain good contact and long service life, keep the adapter clean and free of dust or moisture. Avoid excessive twisting or bending of cables at the connection point and disconnect by pulling the plug rather than the cable.
