Audio cable Procab XLR male to 6.3 mm (1/4") jack male, stereo, 3 m

Procab XLR male to 6.3 mm (1/4") jack male, stereo, 3 m is a purpose-built audio cable for linking equipment with an XLR output to devices that accept a 6.3 mm stereo jack input. With a 3-meter length and a stereo TRS jack termination, this cable supports direct wired connections that may be used in stage, studio and live sound setups where balanced or unbalanced signal routing and format conversion are required.

Advantages

The Procab cable offers reliable physical connections with robust connector housings designed for repeated plugging and unplugging in professional environments. Its 3 m length provides flexibility for positioning between sound sources and destination equipment without excessive slack. The stereo 6.3 mm jack allows TRS connections that can carry balanced signals when wired appropriately, while the XLR male termination ensures a secure fit into standard XLR outputs commonly found on microphones, mixers and outboard gear.

Suitable for

• Connecting mixers, microphone preamps or DI boxes with XLR outputs to amplifiers, headphone amplifiers or other devices with a 6.3 mm TRS input
• Stage and live sound setups requiring short- to medium-length interconnects
• Studio patching where format conversion from XLR to 1/4" stereo jack is necessary
• Instrument and monitoring connections that use balanced or unbalanced wiring schemes

Key specifications

• Cable type: XLR male to 6.3 mm (1/4") jack male, stereo (TRS)
• Length: 3 m
• Signal: Audio, supports balanced or unbalanced connections depending on wiring
• Connector materials: metal housings with strain relief (standard professional construction)
• Typical use: microphone/mixer outputs to TRS inputs for instruments, amplifiers or monitoring

How to use

Insert the XLR male connector into the XLR output of the source device until it locks, and insert the 6.3 mm TRS jack into the target device’s 1/4" stereo input. Verify the target device input expects either a TRS connection or an unbalanced TS input; if the destination is unbalanced, check wiring compatibility to avoid phase or level issues. Power down equipment or lower levels when connecting or disconnecting to prevent clicks or pops. After connecting, set appropriate gain or volume levels on source and destination devices and perform a quick soundcheck to confirm correct channel routing and signal quality.

Usage recommendations

Use the Procab cable with devices that match the intended signal wiring (balanced TRS to balanced XLR or with known unbalanced wiring). For critical signal runs, keep cable length as short as practical and avoid running parallel to power cables to minimize interference. Regularly inspect connectors and strain relief for damage and replace the cable if any shielding or connector integrity is compromised.
