Question 1

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

Accepted Answer

A faulty red channel in the signal path or display

Answer

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

Question 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?

Accepted Answer

Insufficient acoustic treatment causing increased reverberation

Answer

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

Question 3

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

Accepted Answer

Auto-IP via mDNS/Bonjour

Answer

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

Question 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?

Accepted Answer

20 feet

Answer

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

Question 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?

Accepted Answer

Change the microphone's operating frequency to a clear channel

Answer

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