CTS Conducting AV Site Surveys 2

Question 1

What is the primary reason for documenting ceiling height during an AV site survey?

Accepted Answer

To determine projector throw distance and display mounting options

Answer

Ceiling height directly governs projector placement, throw distance, and feasible mounting heights for displays and screens.

Question 2

You discover during a survey that the planned AV room has only two 20-amp circuits for a large system. What is the correct course of action?

Accepted Answer

Document the deficiency and coordinate with the electrical contractor for additional circuits

Answer

Power deficiencies must be documented and resolved through the electrical contractor before AV installation begins.

Question 3

Which environmental factor most significantly increases projector lumen requirements in a space?

Accepted Answer

High ambient light from windows and overhead fixtures

Answer

Ambient light competes directly with the projected image, requiring higher lumen output to maintain adequate contrast ratio.

Question 4

What is the primary HVAC concern when selecting a location for AV equipment racks during a site survey?

Accepted Answer

Ensuring adequate cooling airflow while protecting equipment from dusty air return paths

Answer

Equipment racks generate significant heat and require clean, cool airflow while being positioned away from dusty air return paths.

Question 5

During a survey, you find the facility operates on 208V single-phase power. What AV planning step is required?

Accepted Answer

Verify AV equipment voltage compatibility and plan for step-down transformers if needed

Answer

Many AV devices are rated for 120V, so a 208V supply requires compatibility verification and potential transformer use.
