Cable Procab CAB734/1.5 — 1.5 m stereo 6.3 mm plug to 2 female XLR connectors

Procab CAB734/1.5 is a 1.5 m audio cable that connects a stereo 6.3 mm (1/4") male plug to two female XLR connectors. It is designed to route balanced or split stereo signals from headphone or line outputs to XLR-equipped mixers, preamplifiers and stage equipment. The cable facilitates conversion of consumer or instrument-level stereo outputs into separate left and right XLR channels for live sound, studio patching and other professional audio setups.

Advantages

The cable provides a compact and reliable solution for splitting a stereo 6.3 mm output into two XLR female channels without requiring additional adapters. Its 1.5 m length is suitable for short cable runs between consoles, audio interfaces and stage boxes. The combination of a TRS 6.3 mm plug with two XLR female connectors enables direct connection to professional mixing desks and outboard gear while preserving signal integrity for line-level and balanced connections where applicable.

Suitable for

• Connecting headphone or line outputs to mixers with XLR inputs
• Splitting stereo signals to separate left and right XLR channels
• Studio patching and routing between consumer devices and professional audio equipment
• Live sound setups where a short, reliable stereo-to-XLR connection is needed

Key specifications

• Cable length: 1.5 m
• Input connector: stereo 6.3 mm (1/4") male TRS plug
• Output connectors: 2 × female XLR
• Signal routing: stereo split (left/right) from TRS to two XLR outputs
• Intended use: line-level and headphone output connections to XLR-equipped devices

How to use

Insert the 6.3 mm TRS plug into the headphone or line output of your source device, and connect the two female XLR connectors to the corresponding left and right XLR inputs on your mixer, preamplifier or stage box. Ensure that the source output level and input sensitivity on the receiving device are set appropriately to avoid clipping or excessive noise. For balanced operation, verify that the source provides a balanced TRS output and that the receiving inputs are configured for balanced signals.

Usage recommendations

Use the cable for short runs to minimize potential signal degradation. Avoid excessive bending near connectors and secure connections on stage or in the studio to prevent accidental disconnection. When connecting consumer headphone outputs, set levels conservatively and adjust gain staging on the mixer to maintain headroom.
