Audio adapter Procab CLP206 — 3.5 mm stereo female to 6.3 mm stereo male

Procab CLP206 is a compact audio adapter that converts a 3.5 mm stereo female input to a 6.3 mm stereo male output. It enables a wired connection between consumer devices with 3.5 mm headphone or aux plugs and professional audio equipment or amplifiers with 6.3 mm jacks. The adapter is designed for straightforward mechanical and electrical compatibility without altering the stereo signal path.

Advantages

The adapter offers a simple, space-saving solution for connecting phones, portable players or laptop audio outputs to mixers, amplifiers and studio monitors with 6.3 mm inputs. Its passive design requires no power and preserves the stereo signal. The compact construction makes it easy to carry and insert into crowded patch bays or headphone amplifiers while maintaining a secure physical connection.

Suitable for

• Connecting headphones with 3.5 mm plugs to amplifiers or headphone amps with 6.3 mm sockets
• Linking portable audio players or smartphones to PA systems or mixers
• Using consumer audio sources in studio or stage setups that require 6.3 mm inputs
• Temporary patching in rehearsal rooms, live sound rigs or broadcast environments

Key specifications

• Connector type: 3.5 mm stereo female to 6.3 mm stereo male
• Signal: stereo (left/right) passive transmission
• Construction: compact, inline adapter housing
• Use case: analog, wired audio conversion between consumer and professional jack sizes

How to use

Insert the 3.5 mm plug of the headphone, player or source cable into the adapter's 3.5 mm female socket. Then plug the 6.3 mm male end of the adapter into the amplifier, mixer or other destination device's 6.3 mm input. Ensure connections are fully seated to avoid intermittent contact. No additional configuration or power is required; volume and signal routing are controlled on the source or destination equipment.

Usage recommendations

For best results, use short, direct cables where possible to minimise noise and signal loss. Avoid stressing the adapter at an angle while connected; if the setup will remain permanent or under tension, consider using a short cable with the appropriate connectors instead of a rigid inline adapter.
