AVIXA AVIXA-CTS Online Questions & Answers

• Question 91:

  When a presenter is using a headworn wireless microphone, the sound technician notices a great deal of plosives and breath noise. To correct this problem, the technician should:

  A. Ask the speaker to talk more quietly
  B. Adjust the microphone wireless transmitter gain
  C. Change from an omnidirectional to a cardioid capsule
  D. Adjust the position of the microphone and use a windscreen
  D. Adjust the position of the microphone and use a windscreen

  ---

  Explanation

  Plosives and breath noise occur when air hits the mic capsule directly. This can be mitigated by adjusting the mic's position slightly off-center from the mouth and adding a windscreen to diffuse breath impact. "Correct mic placement and windscreen use significantly reduce plosives and breath noise, especially with headworn microphones."

• Question 92:

  The owner is looking for an audio solution for staff meetings.

  Which question is MOST important to ask to ensure a functioning system?

  A. Are there any remote participants?
  B. Will you use displays or a projector?
  C. Do you want handheld or lapel mics?
  D. Would you like ceiling or surface mount speakers?
  A. Are there any remote participants?

  ---

  Explanation

  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.

• Question 93:

  HOTSPOT

  Which section of the Ohm's Law chart would you use to calculate watts? Select the coned quadrant.

  

  

  ---

  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).

• Question 94:

  Which of the following terms means a complete lighting instrument composed of a lamp and housing?

  A. lux
  B. lumen
  C. luminaire
  D. footcandle
  C. luminaire

  ---

  Explanation

  The term "luminaire" refers to a complete lighting instrument composed of a lamp and housing. This includes all components necessary for the fixture to function, such as the lamp (bulb), housing, reflector, and any other elements that contribute to its operation. Axis Technology Specialist documentation uses the term "luminaire" to describe complete lighting systems in various technical specifications and installation guides.

• Question 95:

  What PRIMARY concern should the sales representative have had during the site survey of this room?

  

  A. room orientation
  B. length of cable runs
  C. ceiling clearance for the projector lift
  D. combination of fluorescent and Incandescent lighting
  C. ceiling clearance for the projector lift

  ---

  Explanation

  The primary concern for the sales representative during the site survey should be the ceiling clearance for the projector lift. Ensuring that there is sufficient space for the projector lift to operate without obstruction is crucial for proper installation and operation. Inadequate clearance can lead to difficulties in mounting and deploying the projector, potentially compromising the projection quality and system functionality. Additionally, it is important to verify that the projector can be positioned at the correct height and angle to achieve the desired image size and alignment.

• Question 96:

  While replacing a lamp in a client's LCD projector, it is important to:

  A. Clean the air filter and reset the lamp timer.
  B. Calculate the new projector throw distance.
  C. Test the projector using a commercially produced DVD movie.
  D. Measure the projector's light output with the new lamp in place.
  A. Clean the air filter and reset the lamp timer.

  ---

  Explanation

  Proper maintenance during lamp replacement includes cleaning the air filter (to maintain airflow and cooling efficiency) and resetting the lamp timer (to allow the projector to accurately track lamp life and provide warnings). Neglecting either may cause overheating or inaccurate lamp life reporting.

• Question 97:

  If the nominal light output of a projector was measured at 5000 ANSI lumens using an f/1.4 lens, what would happen if the lens was changed to an f/2.8 large zoom?

  A. The projected image will be darker
  B. The projected image will be brighter
  C. The screen will need to be changed to 1:1 gain
  D. The screen will need to be changed to a high contrast screen
  A. The projected image will be darker

  ---

  Explanation

  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

• Question 98:

  When addressing system functionality with a client, an integrator should:

  A. Discuss future technologies
  B. Ignore currently installed systems
  C. Suggest sustainable building guidelines
  D. Assess specific requirements and expectations
  D. Assess specific requirements and expectations

  ---

  Explanation

  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

• Question 99:

  When preparing to fly a projector, a technician finds that two of the six mounting bolts for the flyware/mount are stripped.

  What SHOULD the technician do?

  A. Fly the projector and install additional safety cables
  B. Remove the projector until the mount can be repaired
  C. Securely tighten the four working bolts and fly the projector
  D. Use gaff tape to secure the mount around the stripped bolts
  B. Remove the projector until the mount can be repaired

  ---

  Explanation

  Safety is paramount in rigging and flying equipment. A compromised mount (such as one with stripped bolts) must not be used. The proper procedure is to remove the projector and repair or replace the mounting hardware. AVIXA guidelines and industry safety codes emphasize that rigged equipment must be structurally sound.

• Question 100:

  Which document identifies who is responsible for each part of the system delivery, including schedule and scope?

  A. Scope of work
  B. Project charter
  C. Statement of work
  D. Responsibility matrix
  D. Responsibility matrix

  ---

  Explanation

  A Responsibility Matrix (also called RACI) outlines who is responsible, accountable, consulted, and informed for each project task or deliverable. It helps eliminate ambiguity and aligns team expectations. "A responsibility matrix details task ownership and accountability across stakeholders-essential for project clarity."
