  1. A rack-mounted AV system is experiencing thermal shutdowns. The rack has rear exhaust fans but equipment still overheats. What is the most likely design oversight?

    Answer: No blanking panels to prevent hot air recirculation inside the rack

    Without blanking panels, hot exhaust air recirculates to the front of the rack and is re-ingested by equipment, defeating the cooling airflow.

  2. Which video connector type carries both digital audio and video but is limited to a maximum cable length of approximately 15 meters without signal boosting?

    Answer: HDMI

    HDMI carries digital audio and video but has a passive cable length limit of roughly 10–15 meters before signal degradation occurs.

  3. A CTS technician is commissioning an audio system and measures a noise floor of -65 dBu with a maximum signal level of +20 dBu. What is the system's dynamic range?

    Answer: 85 dB

    Dynamic range = maximum signal level − noise floor = +20 dBu − (−65 dBu) = 85 dB.

  4. When designing a video conferencing system, what factor most directly determines whether far-end participants can clearly see presenter facial expressions?

    Answer: Camera field of view and seating distance from the camera

    Camera field of view relative to the distance between the camera and the nearest and farthest participants determines how large faces appear in the video frame.

  5. A CTS professional must verify that a projector screen meets the minimum Contrast Ratio requirements for a presentation space. Which environmental factor has the greatest negative impact on projected image contrast?

    Answer: Ambient light falling on the screen surface

    Ambient light raises the black level of a projected image, compressing the contrast ratio between dark and bright image areas.

  6. During AV system acceptance testing, a CTS professional discovers that audio delay compensation is needed between a video screen and a loudspeaker array positioned 34 feet in front of it. Approximately how much delay should be added to the video signal?

    Answer: 30 ms

    Sound travels approximately 1,130 feet per second; 34 feet ÷ 1,130 ft/s ≈ 30 ms of delay needed on the video path.

  7. Which standard published by AVIXA defines the minimum audio and video performance requirements for AV systems used in corporate boardrooms and conference rooms?

    Answer: ANSI/AVIXA 2M-2010

    ANSI/AVIXA 2M-2010 (Audiovisual Systems Performance Verification) establishes minimum performance criteria for AV systems in professional environments.
