Adam Hall 4 STAR Rean Balanced 1/4" TRS Jack Extension Cable
The Adam Hall 4 STAR Rean Balanced 1/4" TRS Jack Extension Cable is a professional-grade audio utility designed for high-fidelity signal transmission across extended runs. It features 99.999% oxygen-free copper conductors and Rean connectors, making it suitable for extending the reach of guitars, keyboards, and line-level studio equipment.

Overview and Construction
The Adam Hall 4 STAR extension cable is engineered to facilitate longer cable runs without compromising signal integrity. The 6-metre lead is constructed using high-grade materials, specifically 99.999% oxygen-free copper (OFC). This high purity level in the copper conductors is essential for minimising signal distortion and ensuring a transparent audio path.
To protect against external noise, the cable employs dense spiral shielding. This design is particularly effective at reducing electromagnetic interference (EMI), which is a common concern in environments with multiple electronic devices, such as recording studios or complex live stages. The exterior is finished with a soft PVC jacket, which balances the need for physical durability with the flexibility required for easy routing and storage.
Applications
As a balanced TRS (Tip-Ring-Sleeve) extension, this cable is versatile across several audio disciplines. It is frequently utilised to extend the reach of:
- Instruments: Guitars, basses, and keyboards where the player needs more mobility than a standard lead allows.
- Studio Hardware: Connecting DI boxes or line-level sources to audio interfaces or mixing consoles.
- Monitoring: Extending the range of balanced headphones or powered monitors in a stationary or mobile setup.
The 6-metre length is specifically tailored for medium-to-large setups where standard 3-metre cables fall short, providing the necessary slack for mobile performers or remote recording booths.

Sound Character
The primary objective of the 4 STAR series is an authentic sound experience. By utilising OFC conductors, the cable aims to deliver excellent signal clarity. Users can expect a neutral profile that does not significantly colour the tone of the connected instrument or source. The combination of balanced TRS architecture and dense shielding ensures that the noise floor remains low, preserving the dynamic range of the audio being transmitted.
Comparisons
Within the Adam Hall catalogue, the 4 STAR range sits as a professional-tier option, often compared to their flagship 5 STAR series, which typically utilises Neutrik connectors for even more demanding environments.
When compared to budget alternatives like the Gear4Music Essentials range, the Adam Hall 4 STAR offers superior shielding and higher-purity copper. While shorter patch cables, such as the Studiospares Standard XLR variants, are intended for rack internal wiring, this 6-metre extension is purpose-built for distance and physical handling. Unlike instrument-specific cables like the Ernie Ball P06049, which features a straight-to-angle configuration, this extension cable is designed to provide a female-to-male TRS link to lengthen existing connections.
