The HELUSOUND 400 speaker cable is an excellent choice for both professionals and audio enthusiasts. Designed for high flexibility and durability, it is ideal for both stationary and mobile installations. Its construction based on copper wires ensures excellent signal conduction, and the soft outer coating makes it easy to lay and mount.

This cable is a proposition for those who value quality and reliability. It will work in recording studios, conference systems, as well as in stage and estrade installations. Thanks to its resistance to UV radiation, it can be used outdoors without fear.

Construction and user parameters

The HELUSOUND 400 cable is characterized by careful workmanship. Copper wires, although not tinned, provide good conductivity. PVC insulation protects against short circuits and mechanical damage, and the outer PVC coating provides additional protection and flexibility. The black color makes it easy to identify the wires – red and black in the two-wire version.

It is worth noting the operating temperature range – from -10°C to +70°C with flexible use and from -30°C to +70°C with permanent installation. The operating voltage is 300V, and the test voltage reaches 1000V, which guarantees safety of use. The minimum bending radius is 8x the cable diameter for flexible laying and 5x the diameter for permanent installation – this is important when installing in tight spaces.

Advantages in practice

Exceptional flexibility: thanks to the diameter of a single wire of 0.15 mm, the cable is easy to lay even in difficult conditions.
Resistance to external conditions: resistance to UV radiation allows it to be used in outdoor installations without fear of material degradation.
Wide operating temperature range: enables the use of the cable in various environments and climatic conditions.
Safety of use: high test voltage provides protection against short circuits and damage to the audio installation.
Easy identification of wires: color markings (red and black) make it easy to connect the cable to audio devices.
Durability: solid construction with high-quality materials guarantees long-term, trouble-free operation.
