AVIXA Updated CTS Exam Questions and Answers by reyan

Distortion from the loudspeaker is often caused by the input signal clipping, which occurs when the input level exceeds the amplifier's capacity, resulting in a distorted output. Clipping is typically due to overdriven signals, which can lead to speaker damage if unaddressed.

CTS Technology Specialist ReferenceThe CTS materials explain clipping and distortion as common audio issues resulting from improper gain structure, which should be avoided to maintain 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 ReferenceAccording 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.

The responsibility for the installation of conduit in a construction project is typically outlined in the bid (tender) documents. These documents detail the scope of work, responsibilities, and specifications agreed upon during the competitive bidding process. They serve as a binding agreement between the parties and clearly delineate who is responsible for various aspects of the project, including the installation of conduit.

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.
