Connecting a turntable to an amplifier involves more than just plugging in two connectors: the ground connection plays a central role in eliminating hum and noise. Triangle’s RED Stereo RCA cable integrates this ground wire, which is often supplied separately, avoiding the need to buy an additional accessory. Designed for analog sources (turntable, DAC, CD player), it is part of the “Black & Red” cable range launched by the French hi-fi speaker manufacturer.
The core of the RED cable is made of oxygen-free copper (OFC) with a stated purity of 99.99%. This type of conductor reduces micro-impurities that can affect electrical conductivity. Triangle has opted for a multi-stranded structure rather than a solid-core conductor: the signal travels through several twisted wires, which promotes uniform resistance along the entire cable and reduces the risk of breakage in case of repeated handling.
Cables carrying low-level signals are sensitive to electromagnetic interference (motors, transformers, phones). The RED combines several protective barriers, from the inside out: a PVC jacket around the conductor, a copper braid, an insulating aluminum foil, a second PVC layer, then an outer braided cotton sleeve. This final layer provides physical protection for the assembly while giving it a refined finish.
This multilayer architecture does not guarantee total absence of noise in every environment, but it offers solid protection against common sources of interference in a home setting.
The RCA plugs feature gold plating, a common treatment on hi-fi cables to limit oxidation over time and maintain a stable electrical contact. A color code distinguishes the left and right channels. Triangle also indicates the signal flow direction with arrows on the cable, a convention inherited from audiophile practice that consists in orienting the shielding from the source to the amplifier. This indication makes it easier to set up a consistent system.
What sets this cable apart from a standard RCA model is its dedicated ground wire. Turntables require a connection between their chassis and the ground terminal of the amplifier or phono preamp to avoid the characteristic background noise (a 50 or 60 Hz hum depending on the power grid). The RED’s ground wire ends in spade lugs, compatible with standard ground terminals on amplifiers. This integration simplifies installation and avoids additional loose wires behind the hi-fi rack.
The cable is available in 1 meter or 3 meters. The shorter version is suitable for compact setups where the source and amplifier sit on the same piece of furniture. The longer version allows you to separate components, for example to isolate the turntable from vibrations or to accommodate room layout constraints. The weight logically increases with length: 140 grams for the 1 m model, 336 grams for the 3 m.
Triangle structures its cables into three levels: Opéra (entry-level), Black Serie (mid-range) and Red Serie (high-end). The RED Stereo RCA sits at the top of this hierarchy, with a larger conductor cross-section and a more sophisticated construction than the Black models.
Yes, it is compatible with turntables equipped with RCA outputs and a ground terminal. Models with permanently attached cables from the factory will not be able to use it, but most hi-fi turntables offer interchangeable connections.
Yes, Triangle explicitly intends it for this use. The cable is suitable for all analog sources. The ground wire will not be an issue: simply leave it unconnected if the source does not require it.
Red cables use a larger conductor cross-section than Black cables and a more sophisticated construction. Triangle positions the Red series (4 stars) above the Black (3 stars) and Opéra (2 stars) in its product hierarchy.
No, this model is a stereo cable (two channels). For a subwoofer, Triangle offers the RED RCA Y, a mono cable with a Y configuration suitable for the stereo inputs on subwoofers.
