AVIXA Updated CTS Exam Questions and Answers by raisa

"Shock Loads" for equipment mounts refer to sudden additional loads from earthquakes or personnel hanging from the mounts. Shock loads are unexpected forces that can be significantly higher than normal operating loads and can cause structural failures if not properly accounted for. This is particularly important in areas prone to seismic activity or where equipment might be subjected to additional stresses. Axis Technology Specialist documentation highlights the need to design mounts and supports to withstand such shock loads to ensure the safety and durability of the installation.

Foam microphone wind screens should be cleaned using warm water. This method effectively removes dirt and oils without damaging the foam material. Using harsh chemicals, like bleach or alcohol, can deteriorate the foam and potentially affect sound quality.

CTS Technology Specialist Reference

CTS materials on equipment maintenance recommend gentle cleaning methods for foam components, as using harsh solvents can degrade the material and reduce the lifespan of equipment.

The ringed update approach is the best service when new firmware is available for installed equipment across a fleet of conference rooms. This approach involves updating the firmware in phases or "rings," starting with a small group of devices to ensure that the update is stable and does not introduce new issues. Once the initial ring is confirmed to be successful, the update is gradually rolled out to additional groups, reducing the risk of widespread problems. This method allows for controlled testing and monitoring, ensuring that any issues can be addressed before the update is applied to all devices.

The three core performance attributes of any audio system are intelligibility (clarity of speech), loudness (sufficient sound pressure level), and stability (resistance to feedback). These parameters ensure a usable and effective sound reinforcement system.

“For speech reinforcement systems, performance must be measured by intelligibility, loudness, and system stability. Without all three, usability is compromised.”
