  1. When troubleshooting a video system that displays a green tint across the entire screen, which component should you suspect first?

    Answer: A faulty red channel in the signal path or display

    A green tint typically indicates a missing or weak red channel contribution in the signal path or display panel.

  2. A client's conference room microphone system produces an echo that worsens when the room has more occupants. What is the most likely cause?

    Answer: Insufficient acoustic treatment causing increased reverberation

    More people in a hard-surfaced room reflect more sound energy, increasing reverberation and perceived echo.

  3. Which protocol allows a control system to discover and control AV devices automatically over a network without manual IP address configuration?

    Answer: Auto-IP via mDNS/Bonjour

    mDNS (Multicast DNS) with Bonjour/Zeroconf enables automatic device discovery and addressing on a local network without a DHCP server.

  4. A CTS professional is calculating the maximum throw distance for a projector. The room is 40 feet deep and the screen is at the far end. With a throw ratio of 1.5:1, what screen width can the projector fill from 30 feet away?

    Answer: 20 feet

    Screen width = throw distance ÷ throw ratio = 30 ÷ 1.5 = 20 feet.

  5. During a live event, a wireless microphone suddenly drops out intermittently. The technician checks RF spectrum and sees strong interference near the mic's operating frequency. What is the best immediate corrective action?

    Answer: Change the microphone's operating frequency to a clear channel

    Frequency coordination — moving the transmitter to an unoccupied frequency — is the correct real-time fix for RF interference.

  6. What is the primary purpose of a signal flow diagram in an AV system design?

    Answer: To illustrate how signals move between each system component

    A signal flow diagram maps the path of audio, video, and control signals from source to destination across all system components.

  7. A CTS professional needs to ensure speech intelligibility in a reverberant space. Which acoustic treatment approach is most effective?

    Answer: Installing absorptive panels to reduce mid-to-high frequency reverberation

    Absorptive treatment targeting mid and high frequencies reduces RT60 in the speech-critical frequency range, directly improving STI/intelligibility.
