CTS Questions and Answers

The first step in creating an estimate for an RFP is to read the project description thoroughly. This ensures that you fully understand the scope, requirements, and objectives of the project. By doing so, you can accurately determine what is needed, identify potential challenges, and make informed decisions on costs, resources, and scheduling. Starting with a clear understanding of the project description sets

System performance verification occurs when the system is completely installed. This process involves testing all components and ensuring that the system meets the design specifications and functions as expected before it is handed over to the client. It is a critical step for quality assurance and confirming that the installation meets both the technical and functional requirements.

CTS Technology Specialist Reference

According to CTS standards, performance verification is conducted post-installation to validate that the system is operating correctly, helping to address any issues before final client approval.

Yellow-colored zones (any light fixture within the yellow zones directly above the seating area).

In video conferencing, balanced and well-placed lighting is crucial for achieving good facial visibility and reducing harsh shadows. Overhead lights can cast shadows on participants' faces, particularly under the eyes and nose, which can detract from a professional appearance on camera. By dimming lights directly above (in this case, the yellow zones), you reduce the intensity of the light falling straight down onto faces, softening shadows and creating more even lighting.

Dimming lights in the green or blue zones would be less effective, as they are positioned at the perimeter of the room and provide indirect lighting that does not directly influence facial shadows over the conference table.

Comprehensive Detailed Explanation with all Technology Specialist References:

Infrared (IR) wireless microphones are particularly useful in environments where security is crucial. Unlike RF (radio frequency) systems, IR systems use light waves within a specific room or area, which makes them more secure since the signal doesn’t pass through walls. This containment ensures that the transmission remains private and prevents eavesdropping from outside the room. IR systems are ideal for environments like corporate boardrooms or government facilities where sensitive information might be discussed.

While large auditoriums (Option A) may use IR systems, they are generally limited to line-of-sight and aren’t suitable for large spaces due to coverage limitations. Rooms with direct sunlight (Option B) and spaces with high-frequency fluorescent lights (Option D) can cause interference with IR signals, making them less reliable in these settings.

The primary design considerations for a projection system in an auditorium include the viewing cone, viewing distance, and viewing angle. These factors determine the optimal placement and size of the projection screen to ensure that all audience members have a clear and comfortable view. The viewing cone defines the area in which the screen can be clearly seen, the viewing distance impacts the size of the text and images, and the viewing angle ensures the image is visible without distortion from various seating positions.

In AV system schematics, signal flow is traditionally depicted from left to right. Inputs (sources) are placed on the left, and outputs (displays, speakers) are on the right. This makes signal tracing intuitive and consistent for documentation and troubleshooting.

“Standard AV system drawings depict signal flow from left to right, starting at source and ending at output, to provide logical signal tracing.”

— CTS Exam Guide, Documentation and Schematics Chapter

Incandescent lamps generate light by heating a filament inside a glass enclosure. This process is different from fluorescent, CFL, and LED lamps, which rely on gas discharge or semiconductor technology rather than a heated filament.

CTS References: AVIXA CTS Exam Guide, Chapter on Lighting; CTS Handbook, Section on Lamp Types and Their Characteristics.

=========================

Using a cable tester and running a protocol is the best way to verify the proper performance of a CAT cable with a new termination. Cable testers can check for continuity, wiring configuration, signal quality, and performance standards compliance (e.g., Cat 5e, Cat 6). They can detect faults such as open circuits, short circuits, and incorrect wiring, ensuring the cable is terminated correctly and capable of supporting the desired network speeds and protocols.

During an initial customer visit, it is crucial to determine whether you are meeting with the decision maker. This ensures that the person who has the authority to approve the project and allocate resources is involved from the beginning. Identifying and engaging with the decision maker helps streamline the process, address their specific needs and concerns, and increases the likelihood of project approval. This practice is a standard approach in sales and project management to ensure efficient communication and decision-making.

The circuit on the right is a combination parallel/series circuit. In this configuration, two sets of speakers are connected in parallel, and these parallel sets are then connected in series. This type of arrangement allows for balancing the load across multiple speakers while maintaining the desired impedance levels.

Understanding a client’s current and anticipated needs is essential for designing a system that truly supports their workflow. This involves asking targeted questions and assessing the functionality they expect from the AV system.

“Assessing user requirements is foundational to delivering an effective AV solution. Integrators must understand functional expectations to ensure alignment with the delivered system.”

— CTS Exam Guide, Needs Analysis and Client Interaction

To ensure a functioning audio solution for staff meetings, the most important question to ask is whether there are any remote participants. This information is crucial because it affects the system's requirements for microphones, speakers, and possibly video conferencing capabilities. Ensuring that the system can effectively support remote participation will lead to better integration and a more effective communication setup. Axis Technology Specialist documentation highlights the necessity of considering remote participants to provide a comprehensive audio-visual solution that meets all user needs.

The most suitable security method for a small portable projector is a cable lock. Cable locks are specifically designed to secure portable devices like projectors by attaching them to a fixed object, preventing unauthorized removal. This method is both practical and effective for portable devices, as it provides a good balance of security and ease of use without requiring permanent installation or modifications to the device.

Preventive maintenance visits (PM/PMV) are primarily designed to ensure that equipment is functioning correctly and to prevent potential failures. This involves cleaning, servicing, and assessing the equipment regularly to maintain optimal performance and longevity. This is in line with industry standards for preventive maintenance, ensuring reliability and reducing downtime.

The frequency identified by the numbers above each slider of a graphic equalizer is the center frequency. The center frequency is the specific frequency that each slider controls, allowing the user to boost or cut the amplitude of that frequency and those in its immediate vicinity. This helps in fine-tuning the audio signal to achieve the desired sound quality.

The light output of a projection system is typically measured in lumens, which quantify the total amount of visible light emitted by the projector. Lumens measure the projector's brightness, making it a standard metric for comparing different projectors' output capacities.

Lux is used to measure illuminance or the amount of light falling on a surface.

Footcandles is another unit of illuminance, similar to lux but based on the imperial system.

Contrast ratio describes the difference in luminance between the brightest white and the darkest black a projector can produce, not the brightness itself.

CTS Technology Specialist Reference

According to CTS training materials, projector brightness should be specified in lumens, which provides a clear indication of the projector's suitability for different environments and screen sizes.

To calculate watts (P) using the Ohm's Law chart, you would use the sections that involve power formulas. These sections are:

P = V • I

P = I² • R

P = V² / R

These formulas show the relationship between power (watts) and the other electrical quantities: voltage (V), current (I), and resistance (R).

The only cable in the image capable of Ethernet transmission over 1 mile (1.6 km) is C, which is fiber optic cable.

???? Why?

According to the AVIXA CTS Exam Guide and industry standards such as IEEE 802.3:

Twisted pair cables (like A and B) are limited to 100 meters (328 feet) for Ethernet.

Coaxial cable (D) is typically not used for long-distance Ethernet and has high attenuation over distance.

Fiber optic cable (C) can support data transmission over kilometers depending on the type (single-mode or multi-mode). For 1 mile (1.6 km), single-mode fiber is ideal.

From the CTS Exam Guide, 5th Edition – Chapter 3: Networking, it explains:

"For high-speed and long-distance data communication, fiber optic cabling is essential. Single-mode fiber can transmit Ethernet over distances exceeding 10 km, making it the only practical choice for transmissions over 1 mile."

Additionally:

Fiber is immune to electromagnetic interference.

Provides higher bandwidth and lower attenuation compared to copper-based cables.

The amount of air that moves through the credenza is crucial because AV equipment generates heat during operation. Proper ventilation ensures that the equipment does not overheat, which can cause damage and impact performance. Overheating can void warranties as manufacturers typically specify operational temperature ranges and ventilation requirements. Ensuring adequate airflow is a common stipulation in AV equipment warranties. Proper ventilation helps maintain optimal operating conditions, thereby protecting the equipment and upholding warranty terms.

A typical full-range reinforcement system is designed to reproduce the full spectrum of audible frequencies for speech and music. This range is generally between 100 Hz and 15,000 Hz, which covers the fundamentals and harmonics necessary for clear audio reproduction.

“Full-range systems are expected to reproduce the majority of the audio spectrum, usually from 100 Hz to 15 kHz, adequate for both speech and background music.”

— CTS Exam Guide, Audio System Design and Specification

A maintenance plan provides structured information about how and when to service each component in the AV system. It includes model numbers, service intervals, and locations to ensure operational integrity over time.

“The maintenance plan outlines the type and frequency of service for each piece of equipment. It ensures the client has a roadmap for sustaining system performance.”

— CTS Exam Guide, Maintenance and Service Planning

Microphones produce very low voltage analog signals, typically in the millivolt range (often between 1-10 mV). These signals are then pre-amplified before further processing.

“Microphone-level signals are generally less than 1 volt and commonly measured in millivolts, requiring preamps to boost signal strength for processing.”

— CTS Exam Guide, Audio Signal Flow and Levels

For a system that is mission-critical and requires 24-hour operation, an advanced replacement warranty is the best option. This type of warranty ensures that if a piece of equipment fails, a replacement is shipped immediately, often before the defective unit is returned. This minimizes downtime and ensures that the system remains operational, which is crucial for mission-critical applications.

A performance bond provides a third-party guarantee that the contractor will complete the project as specified in the contract and offers protection against financial losses if the project is not completed. This bond ensures that the client has recourse if the contractor fails to meet contractual obligations.

CTS Technology Specialist Reference

CTS study materials note that performance bonds are commonly requested in construction and large AV projects to provide clients with financial protection and assurance of project completion.

The second pattern from the left (the figure-eight pattern).

The figure-eight (or bidirectional) microphone pattern is the most susceptible to feedback among the choices shown. This pattern picks up sound equally from both the front and rear of the microphone while rejecting sound from the sides. Due to its large rear lobe, it is prone to capturing sounds from reflective surfaces or rear-facing speakers, which can lead to feedback in a live sound environment.

Here's a breakdown of the patterns:

First pattern (Omnidirectional): Captures sound from all directions. While it can be prone to feedback, it doesn’t have a rear lobe like the figure-eight pattern.

Second pattern (Figure-eight/Bidirectional): Susceptible to feedback because it picks up equally from both front and back, which can include unwanted sound reflections.

Third and Fourth patterns (Cardioid and Supercardioid): These are more directional with better rear rejection, thus less susceptible to feedback.

Fifth pattern (Shotgun): Highly directional with minimal pickup from the rear and sides, making it the least susceptible to feedback.

CTS Technology Specialist Reference

CTS materials on microphone types and placement emphasize that bidirectional (figure-eight) microphones should be positioned carefully in live sound setups to avoid unwanted rear lobe pickup, which can lead to feedback when speakers are positioned behind or to the sides of the microphone.

A detail drawing provides specific, comprehensive information about particular elements of a project, such as how to hang a loudspeaker line array. These drawings include precise measurements, materials, and installation instructions, allowing technicians to understand the exact requirements and procedures for mounting the equipment. Detail drawings ensure that all aspects of the installation are clearly communicated and followed, preventing errors and ensuring a safe and effective setup.

When conflicts arise between codes and standards, the local authority having jurisdiction (AHJ) takes precedence. The AHJ is responsible for enforcing regulations and has the final say in interpretations to ensure compliance with local requirements.

CTS Technology Specialist Reference

CTS guidelines state that the AHJ has ultimate authority over code interpretation and compliance, which is critical in AV installations to ensure safety and legal adherence.

The images shown represent keystone distortion, which occurs when a projector is not aligned perpendicularly to the screen. This misalignment results in a trapezoidal image rather than a rectangular one.

According to the AVIXA CTS Exam Guide, keystone distortion is covered under the Display Systems section, which states:

“Keystone distortion happens when the projector lens is not perpendicular to the screen plane, often due to improper vertical or horizontal positioning. The image appears wider at one end and narrower at the opposite, forming a shape like a keystone — hence the name.”

This distortion is not related to contrast (A), which refers to the difference between light and dark elements in an image, nor chromatic (B), which pertains to color distortion or aberration. While the shapes resemble trapezoids, trapezoid (D) is a description of the resulting shape, not the distortion type. The technical term for this specific distortion is keystone.

The aspect ratio is the ratio of the width to the height of an image. In the given images, the larger display has a width of 47.6 inches and a height of 26.89 inches. The aspect ratio is calculated as: Aspect Ratio=WidthHeight=47.626.89≈1.77:1\text{Aspect Ratio} = \frac{\text{Width}}{\text{Height}} = \frac{47.6}{26.89} \approx 1.77:1Aspect Ratio=HeightWidth​=26.8947.6​≈1.77:1 This approximates to 16:9, which is a common widescreen aspect ratio used in modern displays and television screens.

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.”

— CTS Exam Guide, Audio Systems Design Chapter

The section with the grayscale bars (bottom row, from white to black)

Brightness calibration is typically done using the grayscale section of a color chart. The grayscale bars provide a range of luminance levels from white to black, allowing the calibration process to adjust the display so that each shade is distinct and accurately represented. Proper calibration ensures that the display shows details in both bright and dark areas of the image, achieving the correct overall brightness.

The main benefit of an externally managed AV/IT service is the cost reduction in operations through clear responsibilities. Externally managed services can streamline operations by clearly defining the roles and responsibilities of the service provider, which leads to more efficient management and utilization of resources. This approach can also provide specialized expertise and support, reducing the need for in-house staff and lowering overall operational costs.

To calculate throw distance, the size of the screen is essential as it determines the distance needed for the projector to fill the screen adequately. Throw ratio calculations depend directly on screen size, impacting projector placement.

CTS Technology Specialist Reference

Throw distance calculations are covered in CTS training, where screen size is the primary factor in determining projector positioning for optimal image display.

For mounting a 50-inch monitor on the south wall of the boardroom, recessed lights labeled as D will need to be separated into their own zone to turn them off when the monitor is on. This will prevent glare and reflections on the screen, ensuring a clear and visible display. Axis Technology Specialist documentation supports the necessity of proper lighting control in AV installations to optimize viewing conditions.

If a client requests a change to the scope of work, such as relocating equipment, the technician should advise the project manager. This ensures that the request is documented and assessed for impact on the project scope, budget, and timeline, maintaining proper project management protocols.

CTS Technology Specialist Reference

According to CTS standards, scope changes should be communicated to project management to ensure appropriate adjustments and approvals are made.

During an initial site survey, understanding the overall scope of the AV solution provides the foundational insight needed for designing a system that meets client requirements. This ensures alignment with objectives and informs subsequent phases of the project.

CTS Technology Specialist Reference

The CTS curriculum advises focusing on the AV solution scope to guide design and implementation processes effectively, ensuring client needs are addressed.

Installers are directly involved with on-site activities and provide essential updates on daily progress, issues, and requirements. Regular updates from installers enable project managers to monitor timelines, resource allocation, and budget considerations more effectively.

CTS Technology Specialist Reference

CTS guidelines highlight the importance of regular communication with installers for tracking project progress, as they are most familiar with day-to-day developments and challenges.

For a rear projection room, it is recommended to paint the room black. Black walls minimize reflections and ambient light, which can negatively impact the quality of the projected image. By reducing these reflections, the contrast and clarity of the projection are improved, providing a better viewing experience. While gray is also a common choice for minimizing light reflections, black is more effective for creating the optimal environment for projection purposes.

A Work Breakdown Structure (WBS) is a hierarchical decomposition of the total scope of work to be carried out by the project team. It breaks down the project into smaller, more manageable components, providing a structured vision of what has to be delivered.

Refraction is the bending of light as it passes from one medium to another with a different density, such as from air to glass. This change in direction occurs because the speed of light changes in different media.

CTS Technology Specialist Reference

In AV, understanding refraction is essential for systems involving optics, such as projectors and lenses, where light paths affect image quality and focus.

The f-number (aperture) of a lens determines how much light passes through. An f/2.8 lens allows less light than an f/1.4 lens, resulting in a dimmer image. Specifically, each full f-stop reduces the light by a factor of four. So switching from f/1.4 to f/2.8 cuts the light significantly.

“The larger the f-number, the smaller the lens opening and the less light is transmitted, which reduces image brightness.”

— AVIXA CTS Exam Guide, Display Technologies Chapter

In a conference room with glass walls, high ceilings, and wooden floors, the biggest challenge would be handling reverberance. These materials and architectural features tend to reflect sound, creating excessive reverberation that can lead to poor speech intelligibility and overall sound quality. Addressing this issue typically involves acoustic treatments to absorb or diffuse sound.

This logistical detail should be planned during the site survey, which is when all site constraints (e.g., power, loading dock access, storage, waste handling) are assessed. Waiting until install day is too late.

“Site surveys must assess disposal options, material storage, and access constraints to avoid delays during installation.”

— CTS Exam Guide, Site Readiness and Installation Planning

Laser phosphor projectors offer longer operational life and lower maintenance needs compared to lamp-based projectors. Because they don’t require frequent lamp changes and generate less heat, they are ideal for hard-to-reach installations where routine maintenance would be difficult and costly.

Comprehensive Detailed Explanation with all Technology Specialist References:

The unique identifier assigned to a network interface card (NIC) is known as the Media Access Control (MAC) address. A MAC address is a hardware address that is permanently embedded into the network interface of a device, such as a DSP, and is used to uniquely identify it on a local network.

When DHCP fails, the control programmer may need the MAC address to reassign the same IP address, as DHCP reservations are often based on MAC addresses. This ensures that devices receive a consistent IP address each time they connect, which is crucial for network devices in an AV system that rely on static IPs for control purposes.

Option B, "internet protocol address," refers to the IP address, which is assigned to a device but not unique to the hardware, as it can change over time. Option C, "network address translation," is a method for modifying IP address information as it passes through a router. Option D, "digital multiplex exchange address," is not relevant in this context and does not pertain to IP networking or AV control systems.

CTS References: AVIXA CTS Exam Guide, Chapter on Networking Fundamentals; CTS Handbook, Section on Network Addressing and IP Allocation.

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.

The primary benefit of a remote monitoring system is that it reduces the need for service calls by allowing technicians to monitor equipment status, detect issues early, and perform diagnostics remotely. This proactive monitoring minimizes downtime and often resolves issues without the need for on-site intervention.

CTS Technology Specialist Reference

CTS training emphasizes the value of remote monitoring in AV maintenance, highlighting its role in reducing service costs and improving system uptime by enabling early issue detection and resolution.

The cloud symbol (Option C) is commonly used to represent a network, particularly in diagrams to signify a network or cloud-based resources. This symbol has become a universal representation of network connections and internet-based services.

A ducker is a feature in audio DSPs that automatically reduces the level of one audio signal when another signal is present. In this scenario, the ducker is likely set to reduce the microphone level when laptop audio is detected. Reviewing and adjusting the ducker settings will resolve the issue.

Comprehensive Detailed Explanation with all Technology Specialist References:

Ambient noise is any unwanted background sound that can interfere with the clarity and intelligibility of the desired audio signal. In an AV setting, ambient noise can reduce speech intelligibility, making it harder for the audience to understand the speaker or experience the audio as intended.

Option B, “canceling it out,” would refer to techniques like active noise cancellation, which isn’t the primary effect of ambient noise on sound but rather a solution to it. Options A and D, “enhancing” and “complementing,” are not applicable because ambient noise typically detracts from audio quality rather than adding to it.

CTS References: AVIXA CTS Exam Guide, Chapter on Audio Basics and Acoustics; CTS Handbook, Section on Acoustic Principles and Noise Management in AV Systems.

The image shows a dynamic microphone, which works through electromagnetic induction. In a dynamic microphone, sound waves cause the diaphragm to move, which in turn moves a coil of wire within the magnetic field of a magnet. This movement generates an electrical signal that corresponds to the sound. The visible components, such as the diaphragm, coil, and magnet, are characteristic of a dynamic microphone’s internal structure.

CTS Technology Specialist Reference

The CTS curriculum details the workings of various microphone types, explaining that dynamic microphones are durable and suitable for live sound due to their ability to handle high sound pressure levels.

A high visibility vest is an example of Personal Protective Equipment (PPE), which is worn to increase safety by making the wearer more visible on-site, particularly in low-visibility or high-traffic areas.

The budget section of a program report describes the probable costs of an AV project. This section outlines the estimated expenses for equipment, labor, installation, and other associated costs, providing the client with a financial overview of the project. Axis Technology Specialist documentation specifies that a detailed budget is essential for planning and managing project finances effectively.

For a room that can function as one large space or be divided into smaller rooms, a control system is ideal. This system can manage audio and video sources across different zones, allowing users to easily switch between configurations depending on room layout. Control systems facilitate seamless operation by centralizing control of AV functions.

CTS Technology Specialist Reference

CTS guidelines recommend control systems for multi-room setups, enabling simplified management of audio and video distribution across spaces that can be reconfigured.

HDCP (High-bandwidth Digital Content Protection) requires an initial handshake to authenticate the connection and ensure content protection. This handshake occurs only when the hotplug circuit is first completed between the source and the display. This process ensures that both devices support HDCP, allowing the secure transmission of protected content. Once established, the HDCP link does not repeatedly handshake unless the connection is reset.

CTS Technology Specialist Reference

The CTS curriculum on digital video interfaces covers the HDCP handshake process and explains that it occurs upon initial connection to prevent unauthorized copying and redistribution of content.
