AVIXA Updated CTS Exam Questions and Answers by zaviyar

Ceiling microphones are sensitive to air handling noise. Coordination with HVAC is crucial to avoid placing microphones near noisy vents or ducts, which can cause unwanted ambient noise and reduce intelligibility.

“Microphones should be kept clear of HVAC vents and diffusers. Coordination with mechanical trades prevents noise contamination.”

Zone D

In a mix-minus audio system, the microphones within each zone are typically routed to the speakers in other zones, excluding the zone they are in. This setup helps to avoid feedback, as it minimizes the likelihood of a microphone picking up sound from a nearby speaker broadcasting the same audio. For Zone C’s microphones to be the loudest, they should be directed to Zone D, which is adjacent to Zone C but not in the immediate vicinity of Zone C’s microphones.

Mix-minus configurations are common in conference rooms and other multi-zone environments, where sound needs to be clear and localized without causing feedback.

CTS Technology Specialist Reference

The CTS guidelines on sound system design discuss mix-minus as an approach to achieve speech clarity and prevent feedback in multi-zone audio systems by broadcasting microphones to other zones rather than the one they are in.

For a design-bid (tender)-build project, the final step for determining the owner's costs for an AV system is ensuring the equipment specification is ready for bid. This step involves finalizing all equipment details, specifications, and requirements so that accurate bids can be obtained from potential contractors. Axis documentation indicates that having precise and detailed equipment specifications is critical for obtaining accurate project costs and selecting the best contractor for the job.

EDID (Extended Display Identification Data) is the protocol that allows sources (such as computers or media players) and displays (such as monitors or projectors) to communicate in order to ensure the display is sent the correct signal. EDID provides a way for the display to convey its capabilities (such as resolution, refresh rate, and color depth) to the source device, enabling the source to adjust its output to match these capabilities, thereby ensuring optimal display performance.
