Commercial AV Foundations

Roles, signals, cables, and reading AV drawings

Build the vocabulary and mental models that every later module relies on: how commercial AV systems are sold, designed, installed, and serviced; what a signal actually is; how it travels from source to destination; and how to read the block diagrams and equipment schedules that define a job.

Key Competency

Read and explain a complete commercial AV signal chain.

Practical Lab

Design a Laptop-to-Display-and-Speaker Signal Chain

Est. 90 minCompetency: Assemble a complete conference-room signal chain with correct devices and cables.

Learning objectives

  • Choose devices to carry laptop video to a display and audio to speakers.
  • Select the correct cable and connector at each hop.
  • Document the chain as a labeled block diagram.
  • Identify where amplification and conversion occur.

Lab brief & instructions

You are designing the AV for a small conference room. A user brings a laptop and wants to present on a wall display while the meeting audio plays through ceiling speakers. Produce a complete, labeled signal chain.

Scenario

Room: one 6-person conference room. Source: a laptop with HDMI or USB-C. Output: one 75" flat-panel display on the long wall and two ceiling speakers. The laptop may also bring a USB camera/mic for soft conferencing, but the lab focuses on presentation audio and video.

Required deliverables

  1. 1List every device in the chain with its stage (source / transport / processing / amplification / output).
  2. 2Specify the cable and connector for each hop.
  3. 3Note every conversion (format, level, digital/analog) and where it happens.
  4. 4Draw a labeled block diagram (hand sketch or simple shapes is fine).
  5. 5Write a one-line purpose for each device.
Expected chain shape

Laptop (HDMI/USB-C) → switcher/scaler or direct → display (video). Laptop audio or separate content audio → DSP or mixer → amplifier → ceiling speakers (audio). If the display is far, an HDBaseT extender over Cat 6 carries the video.

Equipment-free alternative

No hardware? Draw the chain in a free diagram tool or on paper and narrate each hop out loud: 'this cable carries the laptop's video to the switcher; the switcher sends it to the display; the switcher also splits audio to the DSP, which feeds the amp, which drives the speakers.' Verbal narration catches missing pieces fast.

Implementation checklist

  • ✓Every device named with its stage.
  • ✓Cable + connector specified per hop.
  • ✓Conversions marked at the device that performs them.
  • ✓Block diagram labeled and readable.
  • ✓Amplification present only for the speakers, not the video path.

01. Lab: laptop → switcher/scaler → display (video) and → DSP/mixer → amp → speakers (audio).
02. Long display runs use HDBaseT over Cat 6.
03. Mark conversions: format (HDMI/DP), level (line→speaker), D/A at the amp.
04. Label every device and cable; diagram must be readable without you in the room.
