Audio extension cable MicroConnect 20 m — analog audio cable, 20m length

The MicroConnect 20 m audio extension cable extends analog audio connections by providing a single continuous 20-meter lead with a 3.5 mm male to 3.5 mm female stereo connection. It is intended for use where a longer reach is required between audio sources and playback or recording devices, such as linking mixers, amplifiers, speakers, portable audio players, computers or headset jacks. The cable preserves a basic stereo signal path and simplifies routing in live sound, event installations, classrooms and home audio setups.

Advantages

The extension cable offers a straightforward, low-complexity solution to increase the distance between devices without reconfiguring existing cabling. With a continuous 20 m length and standard 3.5 mm stereo connectors, it is compatible with many consumer and professional devices that use a 3-pin stereo AUX jack. The single-cable format reduces the number of intermediate adapters and keeps connections neat in temporary or semi-permanent installations.

Suitable for

• Extending headset or headphone connections to a remote audio source
• Linking a mixer or audio interface to speakers or monitors over a longer run
• Temporary audio routing for events, presentations or rehearsals
• Connecting portable players, smartphones or laptops to sound systems when the device cannot be moved

Key specifications

• Cable length: 20 metres
• Connector type: 3.5 mm male (stereo) to 3.5 mm female (stereo)
• Signal type: Analog stereo (3-conductor TRS)
• Cable design: Single continuous cable for signal extension
• Typical applications: Consumer and semi-professional analog audio connections

How to use

Insert the 3.5 mm male connector into the headphone or line output of the source device, and plug the 3.5 mm female end into the device requiring the audio input, such as headphones, speakers or an amplifier. Ensure both devices are set to appropriate volume levels before playback to avoid sudden loud signals. Route the cable to avoid sharp bends and excessive tension; secure it with ties or tape where necessary to prevent trip hazards in public or stage areas.

Usage recommendations

For best audio quality, avoid running the extension cable parallel to power cables for long distances and keep connections clean and fully inserted. If using with headsets that include a microphone, verify microphone compatibility as some headsets use a combined TRRS connector while this extension supports a 3-pin TRS stereo connection only.
