30 questions spanning all eight weeks: signal fundamentals, control processors, touchpanel UI, audio DSP and AEC, AV networking and Dante, multi-device integration, field commissioning and troubleshooting, and capstone architecture.
Cumulative Final Exam (30 questions)0 / 30 answered
01
On a commercial AV project, the consultant writes the performance spec and the integrator builds, installs, and commissions to it. Which statement best captures the integrator's programming boundary?
02
A ceiling microphone on a 15 m run to a DSP should be connected over which cable/connector, and why?
03
In the five-stage signal path, a matrix switcher belongs to which stage, and how does it differ from an amplifier?
04
A laptop must feed a display 25 m away. What is the most appropriate transport, and what is the risk of a long passive HDMI cable?
05
What distinguishes two-way control from one-way, and why does it matter for the touchpanel?
06
Which control transport is the right choice for a motorized screen lift's up/down trigger?
07
Modeling the room with a `roomState` variable (STANDBY, STARTING, ON, SHUTTING_DOWN) prevents which class of bug?
08
An IR-controlled display shows as 'on' on the panel but is off. What is the root cause, and what fixes it?
09
In the Start sequence, why power the display before routing the source to it?
10
Which is a transferable control concept (not ecosystem-specific)?
11
What is the most common touchpanel design mistake, and what fixes it?
12
What is the minimum touch target size for accessibility on a touchpanel?
13
Which is the best error message for a display that did not respond?
14
A 48 kHz sample rate can faithfully capture audio up to what frequency (Nyquist)?
15
You hear distortion in a room. Which stage is most likely clipping, and what is the fix?
16
What does acoustic echo cancellation (AEC) remove, and what signal does it use as a reference?
17
A switch has 24 PoE ports and a 195 W budget. Each touchpanel draws ~13 W (PoE+). How many can it power?
18
What does IGMP snooping do, and what fails if it is off on an AV-over-IP VLAN?
19
On a Dante network, which switch settings prevent dropouts?
20
A touchpanel has a link light but no discovery and no ping reply; control is on VLAN 100 and the panel is on the corporate VLAN. What is the fault and fix?
21
In an integrated room, which device coordinates all the others and talks to the touchpanel?
22
Why wrap a device's command set and feedback in a driver?
23
Serial feedback arrives split across packets. How should you parse it?
24
What is the safest automation when an occupancy sensor reports the room empty for 10 minutes with no active call?
25
A display does not respond to a power-on command. What is the correct driver behavior?
26
Where do heavy devices like amplifiers go in a rack elevation, and who performs mains panel work?
27
What defines the start of the warranty period, and what does it require?
28
The far end hears echo; local audio is fine. Which is the most likely cause?
29
When isolating a fault, what rule prevents hiding the root cause?
30
Which belongs in the handover package, and what does a one-page quick-start guide left by the panel accomplish?
Accreditation: This final examination is part of the AV Institute LLC course-completion curriculum. It is not an official Crestron, Q-SYS, Biamp, Dante, or AVIXA certification, and carries no manufacturer endorsement. Combined with the capstone project (pass at 80/100), passing at 80% completes the course requirements.
