300 Foot Pro Audio TRS to TRS Balanced Cable - Long Run Clarity

In this review the 300 Foot Pro Audio TRS to TRS Balanced Cable is evaluated for live sound and studio line-out work; it is aimed at engineers and performers who need a long, reliable balanced connection. The single biggest reason to buy is its length combined with a balanced TRS design that preserves clear audio over long runs. The review focuses on construction, expected performance in live setups, and practical considerations for touring or fixed installations.

Key Features

• TRS balanced connectivity: The male-to-male TRS plugs allow balanced line out into mixers and powered speakers for reduced noise over long distances.
• 300 ft length: One continuous long run eliminates the need for multiple shorter cables and reduces connector points that can introduce signal loss or hum.
• PVC black jacket: The flexible PVC covering resists tangles and keeps the cable lightweight for stage use and temporary installs.
• Bare annealed copper conductors: Annealed copper provides good flexibility and reliable conductivity for repeated coiling and deployment.
• Gold-plated REAN connectors: The REAN NYS228BG gold-plated 1/4 in TRS plugs offer corrosion resistance and secure contacts for consistent signal transfer.
• Low capacitance: With 21 pF/ft capacitance and 70 Ohm characteristic impedance, the cable is designed for clear audio with minimal high-frequency roll-off on long runs.

Who It's For

The cable is best for live sound engineers, venue techs, and touring musicians who need a single long balanced run from sources to consoles or speakers without patching multiple shorter cables. It is also suitable for studio situations where a long, permanent cable route is required and balanced connections are preferred.

Those who should look elsewhere include users who need frequent portable setups with heavy handling where a reel or snake with strain relief is preferred, and anyone who needs instrument-level unbalanced TS connections rather than line-level balanced TRS wiring.

Pros & Cons

Pros

• High-quality balanced signal over long distance reduces hum and interference in stage and venue applications.
• Durable, flexible PVC jacket and annealed copper conductors make the cable easy to coil and deploy.
• Gold-plated REAN connectors provide reliable contact and resist corrosion for long-term installations.

Cons

• At 300 ft the cable is heavy to move and may require a reel or additional hardware for transport and storage.
• Not intended for unbalanced instrument-level connections, so adaptors or different cable types are needed for those uses.

Specifications

Our Verdict

The 300 ft Pro Audio TRS to TRS balanced cable is a practical choice for live sound and fixed-install applications where a long, single balanced run is needed. Its construction and low capacitance support clear line-level audio and the gold-plated REAN connectors add durability, making it good value for venues and touring rigs that want fewer connection points and reliable performance.

Frequently Asked Questions

Can this cable be used for microphone runs?
Yes for line-level balanced outputs and some active microphones with TRS line connections, but many microphones use XLR so an adapter or different cable may be required.

Is the cable suitable for outdoor use?
The PVC jacket is robust for indoor stage and temporary outdoor setups, but prolonged outdoor exposure without protection is not recommended.

Will the long length cause noticeable tone loss?
With 21 pF/ft capacitance and balanced wiring, high-frequency loss is minimized for line-level signals over this length, though proper gain staging is still important.
