Course: CTS — Audiovisual & IT Systems  ·  AVIXA Ch. 3–22 · Full Review · Milestone

Sixteen weeks, twenty chapters, one continuous thread: a signal starts as sound or light, becomes a voltage, becomes a number, travels over a network, gets routed and processed, gets designed into a system, gets physically built, gets operated daily, and eventually needs maintenance or repair. Every phase of this course built toward that full picture.

Work through the cumulative review questions below without notes first. Then move to the application checklist — because the actual next step, if the Newark posting is still open when you finish this course, is submitting a real application.

Job posting tie-in: If you're applying to Announcement #26-12: revisit the job posting page, confirm the submission link is still active, and prepare your cover letter, resume, and salary history as one combined PDF exactly as specified.
Practice Questions
  1. Trace a single signal path from Week 1 to Week 11: a witness speaks in a courtroom, and their voice needs to be heard clearly, recorded, and streamed to an overflow room. Name the general stages that signal passes through, in order.
    Show answerMicrophone (analog signal) → A/D conversion & gain staging (Week 1–2) → DSP processing/mixing (Week 3) → control system routing via matrix switcher (Week 5) → recording system capture and streaming media server distribution (Week 14) — all riding on properly designed and terminated cabling/network infrastructure (Week 3, Week 11).
  2. A stakeholder reports “the sound is bad” in a courtroom. List three completely different root-cause categories from across this course that could each independently explain that complaint.
    Show answerAny three of: poor gain staging/noise (Week 1–2), excessive reverberation or HVAC noise from the room's acoustics (Week 9), a loose/poor cable termination (Week 11), a misconfigured DSP or control macro (Week 5), a failed or underpowered device (Week 6/15), or wireless mic RF interference (Week 6).
  3. Why does this course emphasize systematic methods (divide-and-conquer troubleshooting, site surveys, commissioning, documented root causes) over just knowing individual facts about equipment?
    Show answerBecause real AV/IT technician work is mostly diagnostic and process-driven — equipment models change, but the discipline of isolating causes, documenting decisions, and following a repeatable method is what actually prevents and resolves problems reliably, regardless of which specific brand of gear is involved.
