AVIXA AVIXA-CTS Online Practice Questions and Exam Preparation

AVIXA AVIXA-CTS Online Questions & Answers

• Question 51:

  An AV technician has been called to a lecture hall where the presenter complains of a loud squealing noise that makes their presentation inaudible.

  What is the BEST strategy to address the complaint?

  A. Increase the gain for the microphone
  B. Position the microphone away from the presenter
  C. Position the microphone in front of the loudspeakers
  D. Mute unused microphone channels on the audio mixer
  D. Mute unused microphone channels on the audio mixer

  ---

  Explanation

  The loud squealing noise is feedback, often caused by open (but unused) microphones picking up sound from the speakers and reintroducing it into the system. Muting unused channels eliminates that loop and is considered best practice during live sound reinforcement.

  "Muting unused microphones prevents feedback loops and is an essential practice in live sound environments."

• Question 52:

  According to the AVIXA Rack Design standard, what should be the MINIMUM distance between an AC Power cable and a Data Twisted Pair cable?

  A. 25 mm (~1 in)
  B. 50 mm (-2 in)
  C. 100 mm (~4 in)
  D. 300 mm (~12 in)
  C. 100 mm (~4 in)

  ---

  Explanation

  According to AVIXA standards for rack design, there should be a minimum distance of 100 mm (approximately 4 inches) between AC power cables and data twisted pair cables. This spacing helps to reduce the potential for electromagnetic interference (EMI) between power and data cables, ensuring signal integrity and reducing noise.

  CTS Technology Specialist Reference

  The AVIXA standards emphasize proper cable management to minimize interference in AV installations. Maintaining a 100 mm separation aligns with best practices for reducing crosstalk and preserving data quality in networked systems.

• Question 53:

  A client setting terms for "tire protection of existing conditions" would most likely apply to which of tire following project types?

  A. New construction
  B. A technology refresh
  C. A prefabricated building
  D. Expansion of an existing building
  D. Expansion of an existing building

  ---

  Explanation

  A client setting terms for "tire protection of existing conditions" would most likely apply to an expansion of an existing building. This is because protecting existing conditions is crucial when construction activities are taking place adjacent to or within parts of a structure that will remain in use. Ensuring that existing elements of the building are not damaged during expansion work is a key concern.

  References:

  Construction and project management documents often specify requirements for protecting existing conditions during building expansions, as outlined in construction contracts and project specifications.

• Question 54:

  When connecting a condenser microphone, what MUST be included in die system design for it to operate?

  A. mixer
  B. stand
  C. transmitter
  D. power source
  D. power source

  ---

  Explanation

  A condenser microphone requires a power source to operate because it uses an electrostatic principle to convert sound into an electrical signal. This power is typically provided by phantom power supplied by a mixer or an audio interface.

  Without this power source, the condenser microphone will not function. It is crucial to include a power source in the system design to ensure the microphone operates correctly.

• Question 55:

  Which of the following aspects should FIRST be considered at an initial site survey for the location of AV racks?

  A. serviceability
  B. available space
  C. access route restrictions
  D. space allowance for future expansion
  C. access route restrictions

  ---

  Explanation

  When conducting an initial site survey for AV rack installation, the first consideration is often access route restrictions. Ensuring that the racks can physically be brought to and installed in the designated location is crucial before evaluating other factors. If the racks cannot be transported into the space due to door sizes, hallway dimensions, or other access limitations, then installation cannot proceed regardless of space, serviceability, or future expansion.

• Question 56:

  Which of the following terms is defined as a lamp that produces light by heating a filament in a sealed glass housing?

  A. Incandescent Lamp
  B. Fluorescent Lamp
  C. CFL Lamp
  D. LED Lamp
  A. Incandescent Lamp

  ---

  Explanation

  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.

• Question 57:

  Which addressing scheme is used to define a fixed, routable IPv4 address that is locally assigned?

  A. static
  B. DHCP
  C. link-local
  D. DHCP reservation
  A. static

  ---

  Explanation

  A static IP address is a fixed IP address that is manually assigned and does not change. This scheme is suitable for devices that require a constant address, allowing them to be easily located and accessed within a network. Static IP addresses are commonly used for routers, servers, and other essential devices in AV networks.

  CTS Technology Specialist Reference.

  The CTS curriculum covers IP addressing schemes, noting that static IP addresses provide reliability and are preferred for AV equipment requiring stable and consistent network access.

• Question 58:

  Milestones are key events or deliverables in a project. On a Gantt Chart or Network Diagram, milestones are represented by a(n)

  A. circle or oval.
  B. diamond or triangle.
  C. square or rectangle.
  D. asterisk or apostrophe.
  B. diamond or triangle.

  Explanation

  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.

  References:

  Audio equipment manuals and equalizer usage guidelines, such as those from Axis Communications and other audio equipment manufacturers, explain the function of center frequencies in graphic equalizers.

• Question 59:

  Which of the following is an EQ type?

  A. gate
  B. limiter
  C. parametric
  D. compressor
  C. parametric

  ---

  Explanation

  In audio technology, EQ (equalization) refers to the process of adjusting the balance between different frequency components of an audio signal. EQ types are specifically designed tools that allow sound engineers to manipulate frequencies in different ways. The types of EQ generally fall into categories like graphic, parametric, shelving, and band-pass, among others.

  A parametric EQ is a type of equalizer that offers control over three primary parameters: Frequency - the specific frequency to be adjusted.

  Gain - the amount of boost or cut applied to the selected frequency. Q (Quality Factor) - the bandwidth or range of frequencies affected around the selected frequency. Unlike other choices, a parametric EQ provides precise control over these settings, making it highly versatile in audio production. The other options are not types of EQ but rather different types of audio processing tools:

  Gate: Used to control the amplitude of an audio signal, often to suppress noise below a certain threshold.

  Limiter: A dynamics processor that prevents a signal from exceeding a set level.

  Compressor: Reduces the dynamic range of an audio signal by attenuating louder parts above a threshold. CTS Technology Specialist Reference.

  The use of parametric EQ is a standard practice in AV system design, as outlined in the CTS (Certified Technology Specialist) training materials, which discuss various EQ types and their applications in optimizing audio fidelity. Parametric EQs are favored in professional settings for their flexibility and control over specific frequencies, as compared to fixed-frequency or limited-band

  EQs.

• Question 60:

  A client is reporting picture drop-outs in an HDBaseT installation.

  What could be a possible cause?

  A. Incorrect cable type
  B. Incorrect cable width
  C. Incorrect BIOS settings
  D. Incorrect EDID settings
  A. Incorrect cable type

  ---

  Explanation

  HDBaseT requires high-quality Category 6 (or better) cables for stable transmission over longer distances. Using incorrect or lower-quality cables (such as Cat5e or poor shielded variants) can result in dropouts, pixelation, or signal failure.

  "HDBaseT requires Cat6 or Cat6a solid copper cables with proper shielding to maintain signal integrity, especially for 4K content." -CTS Exam Guide, Signal Distribution and Cabling Chapter
