Resources, glossary & completion

Everything you need alongside the lessons: required tools, weekly glossary terms, reflection prompts, and how to finish the course.

Required tools & resources

No hardware is required to complete the course. Equipment-free simulated alternatives are provided for every lab. Where manufacturer software is mentioned, availability and licensing are your responsibility — this course does not assume access to any proprietary simulator or license.

Cable & connector reference drawings

Free

Hand-draw or free-tool diagrams of HDMI, USB-C, XLR, RJ-45, Phoenix connectors for identification practice.

AV block-diagram templates

Free

Free drawing tool (e.g. draw.io/Diagrams.net) for block diagrams, signal-flow, rack elevations, and network diagrams.

Pseudocode simulator (plain text)

Free

Write control sequences as pseudocode in any text editor; 'run' by walking the steps with a partner — no license needed.

Network IP-plan spreadsheet

Free

Any spreadsheet app for IP schedules, VLAN plans, and PoE budget worksheets.

Pink-noise / tone generator (free apps)

Free

Free phone or desktop signal generators for commissioning practice; labeled as free, not pro-grade.

Crestron / Q-SYS / Biamp software (licensed, where available)

Licensed

Manufacturer design/programming software may require accounts or licenses; availability is the user's responsibility. Confirm access through the manufacturer. No simulator availability is assumed.

Physical test bench (optional)

Hardware

A laptop, display, small mixer/amp, and speakers are enough to demonstrate a signal chain. No specific hardware is required to complete the course.

Weekly glossary

The full course glossary — every term used across the eight weeks.

AEC (Acoustic Echo Cancellation)
DSP processing that removes far-end audio picked up by local mics using a reference signal, so the far end does not hear itself.
Automixer
A mixer that auto-opens mics for active talkers and attenuates the rest, keeping the level steady (NOMA).
Balanced audio
A three-conductor audio link (hot/cold/ground) that rejects common-mode noise over long runs; XLR/TRS.
Bit depth
Resolution of each audio sample; e.g. 24-bit gives ~144 dB dynamic range.
Clipping
Distortion when a signal exceeds a stage's maximum; reduce gain at the clipping stage.
Commissioning
On-site testing, tuning, and acceptance that confirms the system meets spec.
Control processor
The computer that runs your program and talks to AV devices; the system's brain.
Crosspoint
A routing switch in a matrix mixer connecting an input to an output.
dBu
A dB ratio relative to 0.775 V; a standard audio level unit.
Dante
A networked-audio standard using standard Ethernet; routes audio over IP with a clock master.
DSP (Digital Signal Processor)
A platform that digitizes, routes, mixes, and processes audio in software.
EDID
Display metadata describing supported formats; part of the HDMI handshake.
Equipment schedule
The line-item list of every device, model, quantity, and location on the job.
Gain structure
Setting levels at each stage so signal is strong but never clips; ~20 dB headroom.
Gateway
The router address a device uses to reach other networks.
HDBaseT
A standard carrying HDMI, Ethernet, control, and sometimes power over Cat cable to ~100 m.
Headroom
Safe margin between nominal level and the clip point; typically ~20 dB.
HPF (High-Pass Filter)
Cuts low frequencies below a point (e.g. 120 Hz) to reduce rumble.
IGMP snooping
A switch feature limiting multicast to joined ports; prevents multicast floods.
Interlock
Logic where selecting one source deselects the others; only one live at a time.
IP address
A device's numeric address on a network (e.g. 192.168.10.20).
Limiter
A dynamics processor with a hard ceiling to prevent clipping; protects speakers.
Matrix switcher
Routes any input to any output; controlled by IP or serial.
Multicast
One-to-many network delivery; efficient for distributing one source to many displays.
Phantom power
48 V supplied over the audio pair to power condenser/array mics.
PoE (Power over Ethernet)
DC power delivered on the data cable to PoE devices; budget by class.
Preamp
A stage that raises mic-level (mV) to line-level (~1 V).
RTA / analyzer
A real-time spectrum analyzer used while tuning audio with pink noise.
Sample rate
How many samples per second represent the waveform (e.g. 48 kHz).
State machine
A model where the room is in one state at a time and events cause transitions.
Subnet mask
Splits an IP address into network and host parts (e.g. /24 = 255.255.255.0).
Touchpanel / UCI
The touchscreen UI the user drives; a Q-SYS UCI deploys to panel/tablet/web.
Two-way control
Control that sends commands and reads status back so the UI reflects the true state.
VLAN
A virtual LAN that separates traffic into broadcast domains at the switch.

Reflection prompts

Use these at the end of each module to make the learning stick.

  1. 01Which signal stage (source, transport, processing, amplification, output) do I still find hardest to trace, and why?
  2. 02Where in my own work have I seen a control panel 'lie' about device state, and what two-way change would fix it?
  3. 03What is one DSP setting (HPF, AEC, limiter) I previously applied by habit that I now understand technically?
  4. 04If I had to hand this room to a new technician tomorrow, what is the one document they would need first?
  5. 05Which design tradeoff (active vs passive speakers, HDBaseT vs AV-over-IP, ceiling vs table mics) would I defend, and to what requirement does it trace?

Course completion

  1. 1Complete all 8 modules in order, including every lab and assignment.
  2. 2Pass each weekly quiz at 80% (retakes enabled).
  3. 3Pass the 30-question cumulative final exam at 80%.
  4. 4Submit the capstone and score at least 80/100 on the rubric.
  5. 5AV Institute may then issue a course-completion certificate.

Accreditation: the8-week bootcamp is an AV Institute LLC course-completion program. It is not an official Crestron, Q-SYS, Biamp, Dante, or AVIXA certification and carries no manufacturer endorsement. Electrical, low-voltage, and code-regulated work requires qualified, licensed personnel.
