PROEL HPC110 RED - "Noiseless" Coaxial Cable for High Fidelity OFC Instruments
The Proel HPC110 Red is the industry standard for high-fidelity instrument connections in professional audio. Designed to Proel's rigorous Italian engineering standards, this coaxial cable offers a definitive solution for musicians, sound engineers, and installers seeking pure, interference-free signal transmission and exceptional durability. Its distinctive red finish not only provides a vibrant aesthetic but also facilitates color coding in complex stages or recording studios, allowing for quick identification of signal lines within a tangle of standard black cables.
At the heart of this cable is OFC (Oxygen-Free Copper) technology, an oxygen-free copper with 99.95% purity. Unlike conventional cables, the OFC manufacturing process eliminates oxygen impurities that cause oxidation and signal distortion at a molecular level. This results in superior conductivity and a crystal-clear frequency response, preserving the natural tone of guitars, basses, and keyboards. Whether for a short patch on a pedalboard or a long run to an amplifier, the HPC110 ensures the sound arrives with the same intensity and nuance as it left the instrument.
The most outstanding feature of the HPC110 is its "Noiseless" architecture. Proel has implemented a double-shielding system that combines a high-density copper spiral with an additional layer of conductive PVC (graphite/thermoplastic). This inner layer acts as a semiconductor, eliminating the triboelectric effect—the annoying "crackling" or static noise heard when stepping on or moving inexpensive cables. Thanks to this construction, the cable is completely mechanically silent, making it ideal for the rigors of live performances where movement is constant.
Main features
-
High Purity OFC Copper: Center conductor made of oxygen-free copper for lossless signal transmission and long-term corrosion resistance.
-
Dual Screen Technology: Combines a copper spiral screen with over 95% coverage and a conductive PVC sub-screen that cancels microphonic handling noise.
-
Polyethylene (PE) Insulation: Provides low capacitance, ensuring that high frequencies (the "brightness" of the instrument) are not attenuated even over considerable lengths.
-
Soft-Flex PVC Cover: The 60 shore PVC outer coating offers a soft touch and extraordinary flexibility, preventing the memory effect and facilitating perfect rolling after each use.
-
Visibility and Organization: The red finish allows for quick visual identification in dark settings or at the back of crowded studio racks.
Benefits for the musician and the technician
For live musicians , the biggest benefit of the Proel HPC110 is peace of mind. Knowing they can move freely around the stage, jump, or step on the cable without it creating unwanted noise is essential for a professional performance. Furthermore, its flexibility prevents the cable from tangling or forming awkward loops around feet or pedals.
For studio engineers and installers , the cable's low capacitance (approximately 120 pF/m) is a critical factor. Many generic cables act as a tone filter, cutting off the high frequencies and making the sound dull. The HPC110 maintains the signal's spectral integrity, which is vital when recording passive instruments like vintage guitars or electric basses. Furthermore, its robust construction withstands repeated soldering and the mechanical wear and tear of touring.
Use cases
-
Custom cable making: Ideal for creating custom length instrument cables with 6.3 mm mono jack connectors.
-
Pedalboard Cabling: Its flexibility and shielding quality make it perfect for short patches between effects pedals, where noise can multiply.
-
Recording Studios: Connecting synthesizers, drum machines and sound modules to mixing consoles or audio interfaces.
-
Fixed Installations: Internal cabling of amplification racks or studios where color coding is required (e.g., Red for sends, Black for returns).
Frequently Asked Questions
-
What does it mean for the cable to be "Noiseless"?
This means it includes a special layer of conductive PVC beneath the copper braid. This layer discharges the static electricity generated by internal friction when moving the cable, eliminating the handling noise common in standard cables.
-
Does this cable work for stereo or balanced signals?
No, the HPC110 is a coaxial cable designed for unbalanced mono signals, which is the standard for guitars, basses, and most keyboard outputs. It has a live conductor and a ground shield.
-
Is this type of cable difficult to solder?
No, it's very simple. OFC copper accepts tin perfectly. You just need to be careful to peel and separate the black conductive PVC layer (the dark layer over the transparent insulation) so that it doesn't touch the central conductor, as it is conductive and could divert the signal to ground.
-
Does the color red affect the quality of the cable?
Not at all. The electrical and mechanical properties are identical to those of the black or blue version. The color is purely a feature of the outer casing for aesthetic and organizational purposes.
