About Audio & Video Cables

Here are some typical use-cases for audio & video cables and how the features above apply:

1. Consumer A/V equipment (home theatres, TVs, game consoles)

  • Cables such as composite RCA (one yellow + red/white) used for standard-definition analog video and stereo audio.
  • Component video cables (separate red/green/blue video lines) for higher-quality analog video.
  • These cables are generally short runs (within a room) so shielding/interference is moderate concern, but good build still matters for image/sound quality.

2. Professional audio/video installations (studios, event venues, broadcast)

  • Multicore cables (thick snake cables) carry many channels of audio (microphones, instruments) in one bundle for efficiency.
  • Balanced audio cables with excellent shielding and impedance control to minimize noise over long runs.
  • Video cables in pro-settings must maintain signal integrity (video jitter, color accuracy) so quality construction, correct impedance and shielding are crucial.

3. Mixed installations: Surveillance, security, AV integration

  • The blog from Nassau mentions CAT 5E/RG6 combo cables for “smart homes” or multimedia installations (audio + composite video) – e.g., running one cable bundle for multiple signals.
  • In such contexts you’ll see thicker jackets, cable labeling, perhaps special jacket materials (low smoke-zero halogen, fire rated) depending on building code.

4. Long-run or high-performance installations

  • When cables need to run across rooms/stages or between buildings, features like low capacitance, proper impedance control, shielding from RF/EMI become critical. The Wikipedia entry on composite video explains how higher quality video cables use lower capacitance dielectric to reduce attenuation. Wikipedia
  • For high bandwidth (HDMI, 4K video) though this falls beyond analog cable examples but same principles (good conductor, shielding, correct design) apply.
