01. A technician setting levels on an analog mixer before a panel discussion is watching a moving-needle indicator on the output section. The needle follows the program material with a deliberate, averaged movement rather than jumping at every transient.
Which indicator are they reading?
a) A VU meter
b) A peak program meter
c) A gain reduction meter
d) A phase correlation meter
02. During a service visit inside the warranty period, a client asks the technician to fit a device they bought themselves into the system rack and wire it into the installed equipment. The signed agreement does not cover that work.
What is the client's most significant risk if the technician agrees?
a) The remaining service credits on the plan are consumed
b) The as-built drawings for the room stop matching reality
c) The warranty on the affected equipment is voided
d) The operator training already booked has to be rescheduled
03. Walking a newly completed courtroom installation with the client, a project manager notices that several items of work the integrator was contracted to complete have not been done.
How should the project manager address this?
a) Reach a verbal agreement with the integrator's site lead to resolve them
b) Issue the integrator a written list of the outstanding items
c) Have the client's own staff finish the items after the integrator leaves
d) Raise the items with the integrator once the project has been completed
04. Near the end of an installation in a hotel conference center, the client says that an entire portion of the project has never been started. The technician on site is not familiar with the work being described.
Which document should they check FIRST to resolve the discrepancy?
a) The program report, which records what the client and the design team agreed the system would do
b) The system schematic, which shows how the installed equipment is interconnected
c) The bill of materials, which lists the components purchased for the job
d) The logic network diagram, which shows the order the activities were planned in
05. A university's technology manager buys the wireless lavalier microphones used across a block of lecture halls. The professors and teaching assistants clip the transmitters on themselves before class and have no interest in how a microphone works.
Which pickup pattern is the BEST choice for these users?
a) Figure-eight
b) Cardioid
c) Hypercardioid
d) Omnidirectional
06. While an AV professional is running audio for a live event, a violin player is added to the stage at the last minute. After a quick sound check the dynamic microphone is not picking up the violin well, so it is swapped for a condenser microphone.
What is the MOST important adjustment to make after changing microphones?
a) Raise the channel fader until the violin sits at the right level in the mix
b) Reset the input preamp gain so the new microphone's level is correct
c) Equalize the channel for the condenser's different frequency response
d) Move the boom so the microphone sits much closer to the instrument
07. An integrator is assembling the team for a stadium AV refit and has to write the position description for the person who will own the schedule and the budget.
Which description belongs in that position?
a) Develops the project plan and monitors progress so the work finishes within its scope, schedule, and budget.
b) Produces the drawings and bill of materials, and selects the components that meet the client's requirements.
c) Terminates and dresses the cabling, racks the equipment, and verifies each subsystem on site.
d) Owns the client relationship, negotiates the contract, and brings the next opportunity to the business.
08. Visiting a retail store, an AV professional notices a steady hiss from the background music loudspeakers between tracks, at the same level whether music is playing or not.
What is the MOST LIKELY cause?
a) Loudspeaker taps set higher than the coverage in the space requires
b) Interference radiated by the store's lighting control gear into the speaker lines
c) A ground loop between the amplifier and the source equipment
d) Gain structure set so that a low source level is made up with amplifier gain
09. A boardroom has run for years on a laptop, a single HDMI cable and a ceiling-mounted projector. The projector has just been replaced with a 4K model. At 1920x1080 the image is fine, but set the laptop to 4K and the projector shows nothing.
What is the LIKELY cause?
a) Content protection is applied to all 4K output and has to be turned off
b) The installed cable cannot carry the bandwidth the 4K signal requires
c) The projector's 4K input mode has not been enabled in its menu
d) The devices simply need a power cycle to renegotiate
10. Midway through a live-streamed panel discussion, the audio from one panelist's microphone becomes distorted and picks up noticeable static. Every other microphone sounds normal.
What is the most appropriate immediate troubleshooting step?
a) Mute the affected microphone, and run the panel on the remaining ones
b) Raise the gain on the affected channel, and trim it back once the level settles
c) Swap the microphone cable, and then the microphone itself if the fault persists
d) Stop the stream, restart the audio system, and then bring the panel back up if the noise clears
