Why Triax Cable Assemblies Are Best for Transmitting Audio and Video

Posted in: Cable Assemblies

In the world of professional audio and video transmission, the choice of triax cable assemblies is crucial to ensuring optimal signal integrity and performance. Among the various options available, 50-ohm and 75-ohm triax cable assemblies emerge as superior choices for transmitting audio and video signals. This blog post explores their unique benefits, particularly when equipped with TRB and TRS jack, plugs, and blunt ends.

A triaxial cable, also known as triax, consists of three conductors: an inner conductor, an insulating layer, and an outer conductor, which is typically also insulated. This tri-layer structure provides several advantages for audio and video applications:

  • Improved Signal Quality: The construction of triaxial cables minimizes electromagnetic interference (EMI) and radio frequency interference (RFI), maintaining signal purity over long distances. This is essential for audio and video applications where high fidelity is paramount.
  • Low Loss Transmission: Due to their design, triaxial cables can deliver signals with lower attenuation compared to traditional coaxial cables. This makes them particularly well-suited for high-definition video applications and professional audio setups requiring long cable runs.
  • Versatility: Triaxial cables can be used in a variety of applications, including broadcasting, live sound, studio recording, and CCTV systems, making them a versatile choice for professionals in different fields.

50-Ohm Triax Cables

  • TRC-50-1 and TRC-50-2 Series: These 50-ohm triax cables are designed to handle high-frequency signals, making them perfect for applications requiring robust video transmission. The 50-ohm impedance is ideal for radio frequency (RF) communications, ensuring excellent signal integrity in diverse applications.
  • TRCH-50-2 Halogen-Free Series: This variant provides the same benefits as standard 50-ohm triaxial cables, with the added advantage of being halogen-free. This characteristic makes it a safer option for installations, reducing the risk of toxic fumes in the event of a fire, making it suitable for use in public spaces or environments requiring stringent safety standards.
  • 322001 High-Temperature Teflon Cables: This cable can withstand higher temperature environments, making it an excellent choice for applications near heat sources or in situations where cables are exposed to elevated temperatures. It maintains performance without compromising the integrity of the signal.

75-Ohm Triaxial Cables

moTrompeter/Emerson TRC-75-1 and TRC-75-2: These 75-ohm triax cables are specifically designed for video and audio applications where matching impedance is crucial for minimizing signal reflections and maximizing performance. They are often used in professional video environments, including broadcast studios and live event broadcasting.

TRB and TRS Jacks and Plugs

The utility of triaxial cables can be maximized through the use of high-quality TRB (tip, ring, and barrel) and TRS (tip, ring, and sleeve) connectors. These connectors facilitate secure and reliable connections, ensuring that the high-quality signal transmitted by triaxial cables is preserved from the source to the destination. Their design helps minimize contact resistance and promote a solid electrical connection, vital in professional audio and video applications.

Blunt Ends for Custom Integration

Both 50-ohm and 75-ohm triax cables can be ordered with blunt ends, allowing users to customize their connector installations based on specific system needs. This flexibility enables technicians and engineers to terminate the cables with connectors appropriate for their unique applications, ensuring compatibility with existing systems.
