CTS EXAM WITH ALL CORRECT & 100% VERIFIED
ANSWERS|UPDATED TO PASS
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?
✔Correct answer-Design Phase
AV Specialists determine the end users needs by examining three things: the required applications,
the tasks, and .... ✔Correct answer-Function of the applications
When verifying a display system, what should be used to determine whether it meets a specified
contrast ratio? ✔Correct answer-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. ✔Correct answer-
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? ✔Correct answer-To test the local device
to see whether TCP/IP is working on the system.

point to point communications
How does knowledge of the overall room function assist the AV system designer in defining the client
needs? ✔Correct answer-Knowledge of the overall room function assists the AV system designer
by providing a starting point from which to determine client needs.
How does the AV team use information about any identified constraints to the AV design and
installation tasks? ✔Correct answer-The AV team uses information about any identified constraints
to the AV design and installation tasks to develop a work-around plan when these constraints will
