XLR Connector ShiverPeaks BS55051 6.3mm Stereo jack adapter

ShiverPeaks BS55051 XLR Connector to 6.3mm Stereo jack adapter is a compact passive audio adapter that converts between a standard three-pin XLR connection and a 6.3 mm TRS phone plug. It is intended for routing balanced or unbalanced line-level and instrument signals between professional audio equipment such as microphones, mixers, outboard processors and amplifiers. The adapter offers a simple, tool-free method to interface devices with different connector types while preserving signal polarity where applications allow.

Advantages

The adapter provides a small and robust passive connection without the need for additional power or circuitry. Its metal housing ensures mechanical durability and shielding from low-level interference in typical studio and live environments. The design supports both balanced and unbalanced wiring schemes when used with compatible gear, allowing flexible use across patch bays, direct connections, and temporary setups.

Suitable for

• Patching microphones with XLR outputs to equipment with 6.3 mm TRS inputs
• Connecting mixers, audio interfaces or outboard processors between XLR and TRS jacks
• Temporary stage or studio wiring where a compact adapter is preferable to re-cabling
• Instrument or line-level signal routing when balanced-to-unbalanced conversion is acceptable

Key specifications

• Connector types: three-pin female XLR to 6.3 mm (1/4") TRS male
• Configuration: passive adapter for analog audio signals
• Compatibility: standard XLR and stereo 6.3 mm TRS connector standards
• Construction: metal housing for mechanical protection and basic shielding
• Use case: suitable for line-level, instrument-level and microphone-level signals depending on equipment wiring

How to use

Insert the three-pin XLR female end onto the corresponding male XLR output of the source device, ensuring correct orientation and a secure fit. Plug the 6.3 mm TRS male into the target device's TRS input or output. Verify signal flow and levels on connected devices before applying full signal to avoid level mismatch. If transforming balanced to unbalanced connections, check the equipment manuals for recommended wiring or grounding practices to prevent hum or phase issues.

Recommendations

For reliable performance, use the adapter in short-term or patching scenarios rather than as a permanent replacement for properly wired cables. Avoid using the adapter in environments with heavy RF interference and inspect connectors regularly for wear or bent pins. When interfacing sensitive microphone preamps or long cable runs, consider using proper balanced cabling or active DI boxes for best noise performance.
