When working with a client to design an AV solution for a new conference center, the
client requests a detailed budget for the equipment and installation. In what project phase
does this occur?
✓ -:- Design Phase
AV Specialists determine the end users needs by examining three things: the required
applications, the tasks, and ....
✓ -:- Function of the applications
When verifying a display system, what should be used to determine whether it meets a
specified contrast ratio?
✓ -:- Spot Photometer
A simple dimmer rack is feeding 24 incandescent lights during a stage production. The rack
is running on a steady 230v AC supply and averaging a current draw of approximately 98
amps. Suddenly the line voltage drops to 211v AC. Calculate the expected draw at this new
voltage.
✓ -:- 90 Amps

The question is to test familiarity with Ohm's Law and the relationships between voltage,
current, and resistance. If the voltage decreases but the load remains constant, than the
current must also decrease. So if the voltage falls from 230 to 211 volts than the current
must fall proportionately. As 211/230=.92 the current drawn will be 98x.92=90.16(90
amps), **Note that incndescenet lamps are a resistive load, not a constant power load such
as an amp or a projector. The answer would be different with a constant power device.
For what purpose would an AV tech designate a loop back internet protocol address in the
range of 127.0.0.1 to 127.255.255.254 in network configuration?
✓ -:- To test the local device to see whether TCP/IP is working on the
system.
In the needs analysis pyramid, what is used to define tasks that will be used to define the
scope of the project?
✓ -:- Applications

While evaluating a potential AC conference room site, you notice the HVAC system
appears to be introducing a substantial amount of noise into the environment. What should
be your first course of action?
✓ -:- Ask to obtain measurements of the HVAC noise using a SPL meter
(A Weighted). Record the measurements and provide them to the design
team to articulate the implications to the client's site.
