Digital Coaxial Audio Cable 0.8 m – RG6 Quad-Shield 75 Ω with Gold-Plated RCA Plugs
A premium-grade digital coaxial interconnect, 0.8 metres long, with one gold-plated RCA plug at each end. It is built on RG6 quad-shielded cable – a 6 mm jacket carrying an oxygen-free copper centre conductor, a foil-and-braid quad shield and an aluminium-mylar wrap. The jacket is printed QUAD-SHIELD 75 OHM DIGITAL INTERCONNECT, which is exactly what it is.
Key product details
- True 75 Ω coaxial lead built on RG6 quad-shielded cable, 6 mm outside diameter
- Oxygen-free copper (OFC) centre conductor with an aluminium-mylar foil shield
- Gold-plated all-metal RCA plugs with spring strain reliefs at both ends
- ONE RCA plug at each end – a SINGLE channel, not a stereo pair
- 0.8 metres – the short run between stacked or side-by-side components
- Digital audio S/PDIF, subwoofer LFE, composite video, RF and analogue audio
About this item
The reason to use a proper coaxial lead for digital audio is impedance. An S/PDIF signal is a high-frequency waveform, and it is specified to travel down a 75 Ω line. A general-purpose RCA patch lead is not impedance-matched, so the signal reflects back along the cable and the receiving DAC has to work harder to recover the clock. This lead is a true 75 Ω RG6 coax, so the waveform arrives intact.
Please check what you are connecting, because it is the one thing to get right. This lead carries ONE channel. If you are connecting a stereo pair – a left and a right – you need two of these, or a twin lead instead.
Where a single channel is exactly right: digital coaxial audio (S/PDIF) between a CD player, streamer, console or TV and an amplifier, soundbar or DAC; a subwoofer feed, because the LFE channel is mono by nature; and the yellow lead of a composite video set, which is one RCA on its own. The wide bandwidth also suits RF and video runs.
At 0.8 metres this is the length for gear that lives together – an amplifier and a disc player on the same rack, a console beside the TV, or a subwoofer amplifier sitting next to the receiver. Short runs keep the signal path tidy without a metre of slack coiled behind the cabinet.

Need to turn an RCA plug through 90 degrees at a matching socket? See our right-angle RCA adapter. This changes connector position only; it does not change analogue/digital signal format.
