HELUSOUND® – The perfect cable series for vivid sound systems

High-quality audio systems are commonly found in venues such as theaters, conference rooms, music stages, churches, parliament buildings, etc. These systems rely on cables that are resistant to electromagnetic interference (EMI) and radio frequency interference (RFI) to preserve signal integrity.

In some instances, audio cables must also meet specific quality standards, such as AES/EBU (Audio Engineering Society/European Broadcasting Union), to ensure professional-grade transmission. This standard requires a sampling rate ranging from 32 kHz to 193 kHz, a bandwidth between 4.096 MHz and 24.5 MHz, and an impedance of 110 ohms ± 20%. These wide-ranging specifications allow compatibility with various cable types, particularly those with an impedance of 88 to 132 ohms, making them suitable for a wide range of digital audio applications.

HELUSOUND® is part of the HELUKABEL series of media and event cables, and it plays a crucial role in sound systems of all scales. Designed for transmitting audio signals, such as music and voice, HELUSOUND® cables are engineered to minimize noise and interference, ensuring optimal sound quality.

The product range is diverse, offering a variety of cables for speakers, musical instruments, microphones, amplifiers, and more. Depending on the application, cables differ in core count and cross-section size. Thanks to their high-performance characteristics, HELUSOUND® cables are ideal for installation in audio systems across residential, commercial, and public settings, or from recording studios to large-scale theaters and stages.

This section introduces some of the standout HELUSOUND® cables designed for various applications.

HELUSOUND® instrument cable is a single-core, double-shielded cable. It is ideal for connecting high-impedance devices such as synthesizers, keyboards, and guitars.

This cable comes in two common cross-sections: 1x0.22 mm² and 1x0.38 mm², with outer diameters of approximately 5.9 mm and 7 mm, respectively. The conductor is made of bare copper, insulated with PE, and the outer sheath is black PVC.

The minimum bending radius for laying for the 1x0.22 mm² cable is 60 mm, while for the 1x0.38 mm² cable, it is 70 mm. The cable operates well within a temperature range of -25°C to +70°C.

The microphone cable is among the most popular ones in the HELUSOUND® series, typically available with 2 or 4 cores. Take the 4-core HELUSOUND® Microphone cable for example. Its cores are optimally twisted together, making it ideal for specialized applications, such as professional studio and microphone techniques.

This cable features two variants, both with a cross-section of 4x0.22 mm². The conductor is made of bare copper with PE insulation sheath, and the core colors are red, black, blue, and green. The outer sheath is black, with material options of either PVC or FRNC, and an outer diameter of approximately 6.1 mm. The cable's minimum bending radius during laying is 62 mm, and it operates within a temperature range of -25°C to +70°C.

Additionally, HELUSOUND® Microphone SC Slim 2-core cable is designed for use in professional stage and studio sound systems. It comes in two variants, with cross-sections of 2x0.15 mm² and 2x0.22 mm², and outer diameters ranging from 4.2 mm to 6 mm. Its conductor is bare copper, with the insulation sheath made of either PVC or PE. The installation requires a minimum bending radius of 42 mm to 60 mm, and like the above cable, it operates in temperatures from -25°C to +70°C.

HELUSOUND® offers a wide range of high-quality speaker cables, commonly available in 2, 4, and 8-core variants. Among them, HELUSOUND® 600 FRNC cable stands out. This halogen-free, non-corrosive cable complies with the EN50267-2-3 Standard, offering flame retardancy, low smoke emission, and the ability to prevent local flame propagation, ensuring the system's integrity. The cable's cross-sections range from 2x1.5 mm² to 8x4.0 mm², with outer diameters between 6.6 mm and 16.8 mm.

The conductor is made of bare copper, and the core insulation comes in black and red. For fixed installations, the minimum bending radius is 33 mm. Also, the cable operates within a temperature range of -5°C to +70°C.

Another notable product is HELUSOUND® 400 PVC cable . This round speaker cable is designed for mobile applications on stages, studios, or in the conference industry. Its technical specifications are similar to HELUSOUND® 600 FRNC cable, with the key difference being the insulation and outer sheath, which are made of PVC. Additionally, HELUSOUND® 400 PVC operates in a slightly different temperature range, from -10°C to +70°C.

The speaker cable catalog also includes the following cables:

· HELUSOUND® 500 PUR

· HELUSOUND® 450 EXTREME FLEX

HELUSOUND® offers a variety of audio cables with multiple core options, ranging from 2, 4, 6, 8, 12, to even 16 cores.

A prime example is HELUSOUND® AUDIO CABLE DIGITAL PVC cable . This 2-core digital audio cable features an earth wire and a flexible spiral-screened shield, making it ideal for long-distance transmissions and handling large data volumes. It is designed to transmit both digital and analog audio signals, commonly used to connect audio amplifiers, digital mixers, DAT recorders, and more.

In terms of specifications, HELUSOUND® AUDIO CABLE DIGITAL PVC cable has a cross-section of 2x0.22 mm². The conductor is made of bare copper, insulated with PE in red and blue colors. The outer sheath is black PVC, with an outer diameter of approximately 5 mm. For laying, the cable's minimum bending radius is 50 mm, and it operates efficiently in temperatures ranging from -25°C to +70°C.

In addition to this audio cable, HELUSOUND® also offers:
