Monoprice Onix Digital Coax Cable

This Monoprice Onix Series cable is a 0.9144 metre coaxial RF lead designed for S/PDIF digital audio, composite video and other line-level RCA signals. It suits home-theatre installers and audio enthusiasts who need a reliable shielded connection between source and amplifier. The CL2-rated jacket makes it suitable for in-wall residential runs. Builders needing longer runs or different connector types should look elsewhere.

75-ohm RG-6/U impedance

The cable uses RG-6/U construction with a 97% pure oxygen-free copper centre conductor and double copper braid shielding to maintain a 75-ohm characteristic impedance. This specification determines whether the lead will pass digital audio and video signals without reflection or loss. A different impedance would make the cable unsuitable for S/PDIF or composite video applications.

Low capacitance and durable jacket

Capacitance is rated at 22 picofarads per foot, helping preserve signal integrity over the cable length. The braided nylon outer sleeve resists nicks and cuts while retaining flexibility for routing through tight spaces. No active components are present, so the cable draws no power and generates no heat or noise during normal use.

Questions about this item

What does the 75-ohm impedance mean once the cable is connected?

It matches the standard for S/PDIF digital audio and composite video, so the signal stays clean between source and display or receiver.

What does the double copper braid shielding cap in practice?

It blocks EMI and RFI that would otherwise degrade the digital audio or video signal running through the RG-6/U conductor.

What does the CL2 rating require for in-wall installation?

The jacket meets fire-safety regulations for residential walls, so the cable can be routed inside walls without additional conduit.
