SSQ audio adapter cable — stereo 3.5 mm jack to 6.3 mm jack (SS-2090)

The SSQ audio adapter cable — stereo 3.5 mm jack to 6.3 mm jack (SS-2090) converts a 3.5 mm stereo output into a 6.3 mm stereo input, enabling direct connection of headphones, smartphones, portable audio players or laptops to audio equipment with a 6.3 mm jack. The adapter is intended for use where compatibility between consumer devices and professional or semi-professional audio gear is required, such as mixers, amplifiers, audio interfaces and powered monitors.

Advantages

The SSQ SS-2090 provides a simple, single-cable solution for adapting connector sizes without introducing signal routing complexity. Its stereo wiring preserves left and right channels for accurate monitoring, and the compact inline design keeps connections tidy in live, studio or home environments. The cable is suitable for repeated insertion and removal where a reliable mechanical fit is required.

Suitable for

• Connecting headphones with a 3.5 mm plug to guitar amps, mixers or studio monitors with 6.3 mm inputs
• Linking portable audio players or smartphones to audio interfaces and amplifiers
• Temporary patching in rehearsal spaces and live sound setups
• Home audio systems where 3.5 mm source devices must feed a 6.3 mm input

Key specifications

• Connector A: stereo 3.5 mm TRS male
• Connector B: stereo 6.3 mm TRS male
• Cable type: stereo audio adapter cable
• Channel configuration: two-channel (left/right) stereo
• Typical use: line-level and headphone-level signals

How to use

Insert the 3.5 mm plug into the headphone or output jack of your source device, then insert the 6.3 mm plug into the input of the amplifier, mixer or monitor. Ensure both devices are powered down or volume is reduced before connecting to avoid loud transients. After connecting, power on devices and adjust levels on the receiving equipment to suit listening or monitoring requirements.

Usage recommendations

For consistent performance, keep connectors clean and avoid excessive bending near the cable ends. Use the adapter cable for short to moderate cable runs and prefer direct connections to maintain signal integrity. When using in live or studio environments, verify channel balance and volume at low levels before increasing to operating levels.
