Frequently Asked Questions
Why is a 0.30-meter length ideal for this cable?
The short 0.30-meter length is specifically engineered for close-range connections, such as linking patch panels to amplifiers or bi-amping adjacent speaker cabinets. It prevents extra cable slack, keeps rack backs clean, and helps minimize resistance-induced signal loss.
What advantage do the 4 x 4 mm² conductors provide?
Thicker 4 mm² conductors offer significantly lower electrical resistance compared to standard 1.5 mm² or 2.5 mm² cables. This is crucial for high-power passive sound systems, ensuring that full amplifier wattage and maximum control (damping factor) reach the speaker voice coils.
Are the connectors on this cable authentic Neutrik parts?
Yes. The cable is terminated with genuine, Swiss-designed Neutrik SPEAKON 4P (NL4FXXWL) cable mount female connectors, widely recognized as the industry standard for safe, robust, and locking audio terminations.
Is this cable suitable for outdoor live sound applications?
Absolutely. The cable features a robust black outer jacket engineered to withstand heavy mechanical stress, friction, and environmental wear typical of pro-touring setups and outdoor festival stages.
