Its 4 meter length offers extended reach without excessive slack, while the molded ends reduce strain at the connection points. The cable is built to handle persistent use in stage and studio environments and is compatible with both balanced and unbalanced circuits, allowing flexible routing and noise reduction when used with balanced equipment.

Suitable for

• Connecting electric guitars, keyboards or other instruments to amplifiers or DI boxes

Key specifications

• Cable length: 4 meters
• Connector type: 6.35 mm (1/4") TRS on both ends

• Color: black
• Application: instrument, line-level and patch connections for stage and studio

How to use

Insert the 6.35 mm TRS plugs fully into the corresponding jacks on your instrument, amplifier, mixer or audio interface to ensure a secure contact. For balanced operation, use devices with TRS-balanced inputs and outputs and route the cable between those balanced connectors. For unbalanced operation, use the cable with compatible unbalanced jacks or adapt wiring as required. Avoid sharp bends near the connectors and unplug by gripping the molded plug body rather than pulling the cable sheath.

Usage recommendations

For best performance, select balanced connections when available to minimize noise on longer runs. Keep the cable away from power transformers and fluorescent lighting to reduce interference. Inspect connectors regularly for wear and clean contacts with appropriate contact cleaner if you notice intermittent signal issues.
