Sound and Light Technician Training

Lesson 1 • Signal Flow Fundamentals

Traces how audio and lighting signals travel from source to output. Understanding signal flow prevents patching errors and troubleshooting confusion later.

Lesson 2 • Physics of Sound

Covers frequency, wavelength, amplitude, and the speed of sound in air. Establishes the acoustic vocabulary used throughout all subsequent audio chapters.

Lesson 3 • Physics of Light

Introduces electromagnetic spectrum, color temperature, and photometric units. Provides the optical foundation required for fixture selection and design work.

Lesson 1 • Microphone Types and Selection

Compares dynamic, condenser, and ribbon microphones by transducer principle and polar pattern. Correct mic selection directly affects capture quality for every source.

Lesson 2 • Wireless Audio Systems

Introduces RF fundamentals, frequency coordination, and antenna placement for wireless microphones and in-ear monitors. Reliable RF operation requires systematic frequency planning.

Lesson 3 • Loudspeaker Systems and Amplification

Examines speaker types, amplifier classes, and system configurations including line arrays. Students match amplifier power to speaker ratings and configure crossover points.

Lesson 4 • Signal Processors and Outboard Gear

Covers dynamics processors, equalizers, reverb, and delay units in the signal chain. Proper processor use shapes tone and controls dynamics without degrading audio quality.

Lesson 1 • Atmospheric and Special Effect Devices

Introduces haze, fog, strobe, and UV fixtures used to enhance visual impact. Safe operation of atmospheric devices requires knowledge of fluid types and ventilation needs.

Lesson 2 • LED and Moving Light Fixtures

Examines LED source technology, moving head mechanics, and fixture attribute channels. Moving lights expand creative range but require deeper DMX channel management.

Lesson 3 • Power Distribution for Lighting

Covers dimmer racks, distros, socapex wiring, and load balancing across phases. Correct power distribution prevents tripped breakers and equipment damage during shows.

Lesson 1 • DMX512 Protocol and Network Design

Explains DMX universe structure, addressing, termination, and data refresh rates. Correct network design eliminates flickering and communication errors across all fixtures.

Lesson 2 • Networking and Remote Control

Covers Art-Net, sACN protocols, and remote console operation over Ethernet. Network-based control enables multi-console setups and remote programming tablets.

Lesson 3 • Effects and Chases

Introduces built-in effect engines, chases, and pixel mapping for dynamic looks. Effects programming adds movement and rhythm that static cues cannot achieve.

Lesson 4 • Fixture Patching and Profiling

Covers console patching, fixture library selection, and custom profile creation. Accurate patching ensures every console control maps correctly to physical fixture attributes.

Lesson 1 • Rigging Fundamentals

Covers load calculations, hardware ratings, and rigging point inspection for overhead equipment. Every rigging decision must account for dynamic loads and safety factors.

Lesson 2 • Truss Systems and Ground Support

Examines truss types, ground support tower assembly, and pre-rig procedures. Correct assembly sequence prevents structural failure during load-in and show operation.

Lesson 3 • Health, Safety, and Risk Assessment

Covers risk assessment documentation, personal protective equipment, and emergency procedures for live events. Proactive safety planning protects crew, artists, and audiences.

Lesson 1 • System Alignment and Tuning

Uses measurement software, real-time analyzers, and time alignment tools to optimize system response. Aligned systems translate the mix engineer's intent accurately to the audience.

Lesson 2 • Mixing Techniques for Live Performance

Applies EQ, dynamics, and effects decisions in real time during a live performance. Reactive mixing skills separate competent engineers from exceptional ones.

Lesson 3 • Stage Patching and Input Lists

Covers stage box wiring, input list creation, and gain structure from stage to console. A clean input list prevents confusion during load-in and soundcheck.

Lesson 4 • Soundcheck Workflow

Establishes a systematic soundcheck sequence for individual sources and full-band balance. Efficient soundchecks respect artist time and reveal system issues before showtime.

Lesson 1 • Principles of Stage Lighting Design

Covers angle, intensity, color, and texture as the four core design variables. Understanding these variables enables intentional, expressive lighting choices for any production.

Lesson 2 • Show Programming for Theater and Corporate

Adapts programming techniques for scripted theatrical cues and corporate presentation needs. Different event types demand distinct cueing philosophies and console workflows.

Lesson 3 • Rig Planning and Plot Creation

Teaches lighting plot drafting, fixture scheduling, and channel assignment documentation. A complete plot enables efficient load-in and clear communication with the crew.

Lesson 4 • Focus and Beam Shaping

Covers safe ladder and lift procedures for focusing conventional and moving fixtures. Precise focus ensures each fixture illuminates its intended area without spill.

Lesson 1 • Preventive Maintenance and Equipment Care

Covers cleaning schedules, firmware updates, connector inspection, and storage practices. Regular maintenance extends equipment life and prevents show-day failures.

Lesson 2 • Show-Day Communication and Coordination

Establishes protocols for intercom use, cue calling, and cross-department coordination during live events. Clear communication prevents missed cues and safety incidents.

Lesson 3 • Systematic Fault-Finding Methods

Introduces signal-path isolation, substitution testing, and divide-and-conquer diagnostic logic. A structured approach resolves faults faster than random component swapping.

Lesson 4 • Common Audio Faults and Fixes

Addresses hum, buzz, dropout, feedback, and distortion causes with targeted remedies. Recognizing fault signatures quickly minimizes downtime during live events.
