PROEL HPC505 BLUE - Reduced Diameter Coaxial Speaker Cable (6.4 mm)
The Proel HPC505 in blue is a specialized technical solution designed to solve one of the most common problems in the installation of sound systems and configuration of audio equipment: the incompatibility between large gauge speaker cables and standard size connectors such as Jack or XLR.
High-quality speaker cables typically have a thick coating that makes it difficult or impossible to properly seal the housing of 1/4" jack or XLR connectors. The HPC505 is manufactured with an optimized two-conductor coaxial geometry that maintains low impedance signal transmission in a profile of only 6.4 mm . This ensures a perfect, secure, and stress-free fit on the connectors, guaranteeing a reliable and long-lasting solder joint.
Its flexible PVC cover in a distinctive blue color not only makes it easy to handle on stages and in studios, but also allows for quick visual identification, avoiding critical confusion between instrument cables, microphone cables and charging cables, thus protecting the integrity of your equipment.
Main features
-
Reduced Diameter Design: With a thickness of 6.4 mm, it is specifically calibrated to fit without forcing into standard mono/stereo jack and XLR connector glands.
-
Coaxial Speaker Construction: Unlike instrument cables (which are high impedance), this cable offers low impedance to efficiently transmit amplifier power to the speaker.
-
High Flexibility: Made with a soft PVC cover that allows for easy rolling and prevents the memory effect, ideal for mobile use.
-
OFC Copper: Oxygen-Free Copper Conductors to minimize oxidation and maintain signal quality over time.
-
Safety Blue Color: Allows you to instantly differentiate it from traditional black microphone cables in low-light environments.
Benefits for the user
The main benefit of the Proel HPC505 is its ease of assembly . If you've ever struggled to close a jack connector onto a 2x1.5mm or 2x2.5mm parallel speaker cable, you know it often ends up breaking the plastic or leaving the cable exposed. This model eliminates that risk, offering a clean, professional finish.
Furthermore, its robust yet lightweight construction reduces the weight hanging from the input jacks of your speakers or heads, preventing damage to the female ports of your valuable sound equipment.
Recommended use cases
-
Passive Sound Columns: Ideal for portable PA systems or installation columns that use Jack or XLR inputs instead of SpeakON.
-
Head - Cabinet Connection: Perfect for guitarists and bassists who need a reliable power cable to connect their amplifier to the cabinet.
-
Discreet installations: Its slim profile allows it to be easily hidden in strips or corners in fixed installations of background music or public address systems.
-
Custom adapters: Manufacturing of SpeakON to Jack or XLR to Jack adapter cables for legacy (old) equipment.
Frequently Asked Questions
Can I use this cable to connect my guitar to the amplifier?
This is not recommended as a first option for the instrument itself. Although it would work, this is a speaker cable designed for power, not a shielded instrument cable. Its correct use is between the amplifier and the speaker.
Does it work for active (self-powered) speakers?
If the active speaker receives a line-level signal, you should use a balanced microphone cable. This HPC505 cable is designed to carry a powered signal from an external amplifier to a passive speaker.
Why is it blue?
Color is a visual standard to differentiate power (load) cables from signal (microphone/line) cables, preventing incorrect connections that could damage the equipment.
Project description
HPC505 two-conductor coaxial speaker cable with a 6.4 mm diameter flexible PVC outer jacket, designed for easy insertion into XLR and 1/4" jack connector housings. Low-impedance off-coated copper (OFC) conductors for power transmission in columns and passive systems. Blue jacket color for quick identification in cable management.
