PD-Connex RX14 - Professional 100V Line Speaker Cable (2x2.5mm², 100m)
The PD-Connex RX14 is a professional two-core speaker cable specifically designed for use in 100V line audio systems. Presented on a convenient 100-meter reel, this cable is the ideal solution for commercial sound installations and public address (PA) systems requiring long cable runs and multiple speakers. Its robust construction ensures clear and reliable audio signal transmission, minimizing power loss and maintaining sound integrity over long distances.
Each of the two conductors is made of high-quality copper, composed of 45 strands, and has a cross-sectional area of 2.5 mm². This generous cross-section reduces electrical resistance, a crucial factor for optimal performance in 100V systems. The conductors are protected by color-coded internal insulation (red and black) that facilitates correct polarity identification during installation, saving time and preventing connection errors. The entire assembly is encased in a flexible yet highly durable black PVC outer jacket with a total diameter of 8 mm, which protects the cable from mechanical damage and everyday wear and tear.
Main features
-
100V Line Design: Optimized for high voltage audio distribution systems, ideal for public address and background music installations.
-
Copper Conductors: Made with two braided copper conductors (45 strands of 0.26mm) for excellent conductivity and flexibility.
-
2.5mm² section: The 2.5mm² cross-section per conductor ensures low signal loss, even in long runs.
-
100 Meter Roll: Sufficient length to cover large areas such as industrial warehouses, shopping centers or office buildings without the need for splices.
-
Protective Cover: The black PVC outer coating is durable and flexible, making it easy to install in ducts, walls or false ceilings.
-
Identifiable Polarity: The internal insulation of the conductors is colored for quick and safe polarity identification.
Benefits for the installer and the system
The PD-Connex RX14 cable is designed for maximum reliability and efficiency. For installers, its flexibility and clear pole identification simplify the assembly process, reducing time and the risk of errors. For the sound system, the quality of its materials guarantees clean and powerful audio transmission, ensuring that each speaker in the line receives a high-quality signal, essential for clear voice announcements and background music.
Use cases
This cable is the perfect choice for a wide variety of professional fixed sound installations, including:
- Public address and voice evacuation systems in schools, hospitals and public buildings.
- Ambient music installations in restaurants, hotels, supermarkets and shops.
- Sound reinforcement for large spaces such as warehouses, factories, sports halls and conference centers.
- Distributed audio systems in offices and business complexes.
Frequently Asked Questions
- Can I use this cable to connect high-fidelity speakers at home (4 or 8 ohms)?
- This is not recommended. This cable is specifically designed for 100V line systems. For low-impedance home systems, it's best to use standard speaker cables, as they offer characteristics better suited to those applications.
- What is a 100V line system and why does it need a specific cable?
- It's an audio distribution system that uses a high voltage (100V) to send the signal over long distances to multiple speakers with minimal power loss. It requires a cable with good insulation and a suitable conductor cross-section, such as RX14, to handle the voltage and ensure low resistance.
- Is this cable suitable for outdoor installations?
- The cable is designed primarily for indoor use. If outdoor installation is required, it must be protected within a suitable conduit or duct to shield it from the elements and UV radiation.
- Why is a conductor cross-section of 2.5mm² important?
- A larger cross-sectional area of the conductor reduces its electrical resistance. Over long distances, this translates to less power loss in the audio signal, ensuring that speakers farther from the amplifier receive adequate power and sound quality.
