Question 1

[Developing AV Solutions] Which method of control is supported by HDBaseT?

Accepted Answer

C

Explanation: The HDBaseT standard is defined by its "5Play" feature set, which enables the convergence of five different signals over a single category cable. One of these five "plays" is control. The HDBaseT specification natively supports the pass-through of common AV control signals, including bidirectional RS-232, Consumer Electronics Control (CEC), and Infrared (IR). This allows a control system to send commands to a remote device, such as a projector or display, using the same infrastructure that delivers video and audio. RS-232 is a fundamental and widely used serial communication protocol for device control in professional AV systems, making its inclusion in the HDBaseT standard essential. CertEmpire.com

Question 2

[Conducting a Needs Assessment]
During a site survey, a client states that there will be no acoustical treatment to their new council
chamber and they want a voice lifting (reinforcement) system. Which loudspeaker should be
recommended to achieve optimal speech intelligibility?

Accepted Answer

C

Explanation: In an acoustically untreated space, such as the described council chamber, sound will reflect off hard surfaces, creating high reverberation that degrades speech intelligibility. The primary strategy to overcome this is to maximize the direct sound reaching the listeners while minimizing the sound energy that excites the reverberant field. A narrow beam loudspeaker achieves this by focusing sound precisely onto the audience area and away from reflective walls and ceilings. This improves the direct-to-reverberant sound ratio, which is a critical factor for achieving optimal speech intelligibility in challenging acoustic environments. CertEmpire.com

Question 3

[Developing AV Solutions] According to AVIXA Standards, what is the MINIMUM load rating for truss that will hold a 5000 lbs (2268 kg) LED wall?

Accepted Answer

B

Explanation: According to AVIXA's official study materials and widely adopted industry standards (such as those from ESTA/ANSI), a minimum safety factor of 5:1 is required for the overhead suspension of static loads like an LED wall. This means the rigging system, including the truss, must be rated to support at least five times the weight of the load it will carry. For a 5,000 lbs load, the minimum required load rating is calculated as: 5,000 lbs × 5 = 25,000 lbs. This ensures the system can safely handle the static load and provides a margin for unforeseen stresses. CertEmpire.com

Question 4

[Developing AV Solutions] What key specification of an owner furnished credenza will a technician need to know that may impact the warranty of the AV equipment?

Accepted Answer

C

Explanation: Audiovisual electronic components generate heat during operation. Manufacturer warranties are contingent upon the equipment being operated within specified environmental conditions, most notably, a safe temperature range. An owner-furnished credenza, not being a purpose-built AV rack, may lack adequate ventilation. Insufficient airflow can cause equipment to overheat, leading to premature failure and voiding the manufacturer's warranty. Therefore, the amount of air that moves through the credenza (its thermal management capability) is the most critical specification for a technician to verify. CertEmpire.com

C. https://kxbjsyuhceggsyvxdkof.supabase.co/storage/v1/object/public/file-images/Avixa_CTS_Exam_Questions/page_149_img_3.jpg? ? D. https://kxbjsyuhceggsyvxdkof.supabase.co/storage/v1/object/public/file-images/Avixa_CTS_Exam_Questions/page_150_img_1.jpg? ?

Accepted Answer

B

Explanation: The image in option B displays a DE-9 (often colloquially called DB-9) D-subminiature connector. This connector is the de facto standard for RS-232 serial communication in most modern computing and audiovisual applications. It is widely used for controlling devices such as projectors, video displays, and control systems. While the original TIA/EIA-232 standard specified a larger 25-pin (DB-25) connector, the 9-pin version became dominant because most applications do not require all 25 pins. The DE-9 provides the essential pins for transmit (TXD), receive (RXD), and ground (GND), which are sufficient for most AV control tasks. CertEmpire.com

Question 6

[Developing AV Solutions] What is the aspect ratio in these images? https://kxbjsyuhceggsyvxdkof.supabase.co/storage/v1/object/public/file-images/Avixa_CTS_Exam_Questions/page_63_img_1.jpg? ?

Accepted Answer

B

Explanation: AVIXA identifies aspect ratios by integer width-to-height notation (CTS-D Handbook, Ch. 11, “Image Display Fundamentals”). A rectangle whose long side is only 33 % wider than its short side is the traditional computer/video shape—an aspect ratio of 4:3 (1.33:1 in decimal form). AVIXA documentation and standard display-resolution charts (e.g., XGA 1024×768, SXGA+ 1400×1050) all describe this shape as 4:3.

Question 7

[Developing AV Solutions] In an audiovisual system where a touch panel is to be connected to the control system via the LAN, the designer may choose to use a

Accepted Answer

C

Explanation: A static IP address is a fixed, manually configured address that does not change. In a professional AV installation, reliability is paramount. For critical components like a control system and its primary user interface (the touch panel), a static IP address ensures that the devices can always locate and communicate with each other predictably. Using a dynamic address (assigned by a DHCP server) would risk the address changing, which could sever the connection and render the touch panel inoperable until the new address is discovered, an unacceptable point of failure in a control environment.

Question 8

[Developing AV Solutions] After there is an approved labor change to a project, what should the project manager do NEXT?

Accepted Answer

A

Explanation: Upon the approval of a labor change, the project manager's immediate responsibility is to integrate this change into the project's master plan. A change in labor directly impacts resource allocation and task durations, making an update to the project schedule the most critical next step. This action ensures that the project timeline accurately reflects the new scope of work and resource availability, allowing for proper tracking and management of subsequent project activities. This process is central to maintaining control over the project's execution and managing stakeholder expectations regarding the project's completion date. CertEmpire.com

Question 9

[Developing AV Solutions] When an audio device can no longer accurately reproduce the audio signal, It is called

Accepted Answer

C

Explanation: Distortion is the most accurate and comprehensive term for any alteration of an original audio signal's waveform as it passes through a system. When an audio device can no longer accurately reproduce the signal, it is, by definition, introducing distortion. This can manifest in various forms, such as clipping (when an amplifier is overdriven), harmonic distortion, or intermodulation distortion. The core of the issue is the failure to maintain the original signal's integrity, which is the definition of distortion. CertEmpire.com

Question 10

[Developing AV Solutions] When choosing an amplifier for a 70 V system, what amplifier output would be the BEST option for a space with 12 speakers, each tapped to 30 W?

Accepted Answer

A

Explanation: To determine the best amplifier, first calculate the total power load required by the speakers. This is done by multiplying the number of speakers by their individual power tap setting: 12 speakers × 30 W = 360 W. According to AV system design best practices, an amplifier should have power headroom of at least 20-25% above the total speaker load to prevent clipping and potential damage. Calculating with a 25% headroom: 360 W × 1.25 = 450 W. The 500 W amplifier (Option A) is the only choice that safely exceeds the 450 W requirement, providing adequate power and headroom for optimal performance in a single-channel 70 V configuration.

Question 11

[Developing AV Solutions] Assuming that the screen and projector are both Ethernet controllable devices, where does the control system for the AV solution need to exist?

Accepted Answer

A

Explanation: The question specifies that the devices are "Ethernet controllable," meaning they are controlled via commands sent over an IP network. For the control system to send commands and the devices to receive them, both the controller and the controlled devices must be connected to the same logical network. This network connectivity is the fundamental requirement for operation, regardless of the system's physical location. The physical placement in a rack or specific room is an implementation detail, not a prerequisite for functionality. CertEmpire.com

Question 12

[Designing AV Systems] In order to mount a projector so that it is horizontally centered with the suspended screen, the technician should look at which drawings in the plans?

Accepted Answer

D

Explanation: A Reflected Ceiling Plan (RCP) is a technical drawing that shows a view of the ceiling as if reflected onto the floor. Its primary purpose is to show the precise locations of all objects on the ceiling plane, including light fixtures, HVAC diffusers, and AV equipment like projectors and the mounting points for a suspended screen. To ensure the projector is horizontally centered with the screen, the technician must consult the RCP, which provides the necessary top-down plan view with dimensions for accurate horizontal (x-y) placement. CertEmpire.com

Question 13

[Conducting a Needs Assessment] Which of the following is addressed within the Needs Analysis part of the AV Design process?

Accepted Answer

D

Explanation: The Needs Analysis phase, also known as the Program Phase in AVIXA standards, is fundamentally focused on defining what the AV system must do to meet the end-user's goals. This process involves interviewing stakeholders to elicit, analyze, and document the system's specific capabilities and tasks. These documented outcomes are the functional requirements, which form the basis for all subsequent design and engineering decisions. The core purpose of this phase is to translate user needs into a concrete set of system functions. CertEmpire.com

Question 14

[Developing AV Solutions] Which of the following protocol allows sources and displays to communicate in order to ensure the display is sent the correct signal?

Accepted Answer

C

Explanation: Extended Display Identification Data (EDID) is a standardized data structure that a display device (e.g., monitor, projector) communicates to a source device (e.g., computer, Blu-ray player). This data informs the source about the display's capabilities, including its native resolution, supported video timings, and color space. The source then uses this information to output a video signal that is perfectly matched to the display's specifications, ensuring compatibility and optimal image quality. This process of communication is fundamental to modern plug-and-play display connectivity. CertEmpire.com

Question 15

[Developing AV Solutions] Installing an AV system generates a lot of debris. When is the BEST time to identify if there will be a place to dispose of the debris?

Accepted Answer

B

Explanation: The initial site survey is the designated project phase for assessing the physical environment and identifying all logistical requirements and constraints. This includes determining access routes, power availability, and arrangements for waste and debris removal. Identifying the disposal location during the site survey allows for proper planning, scheduling, and inclusion of any associated costs in the project proposal, preventing delays and unforeseen expenses during the installation phase. This proactive approach is a fundamental principle of effective AV project management. CertEmpire.com
