Sound System Training

Lesson 1 • Room Acoustics Fundamentals

Explains reflection, absorption, diffusion, and reverberation in enclosed spaces. Prepares students to diagnose acoustic problems before touching equipment.

Lesson 2 • Signal Flow Concepts

Traces the path of an audio signal from source to speaker at a conceptual level. Provides the mental model that underpins all system design and troubleshooting.

Lesson 3 • The Decibel Scale Explained

Introduces logarithmic measurement of sound pressure and power levels. Students gain the maths skills needed to read meters and set gain structures.

Lesson 4 • Human Hearing and Perception

Examines the auditory system, equal-loudness curves, and psychoacoustic effects. Links physical measurements to subjective listener experience.

Lesson 1 • Microphones: Types and Characteristics

Covers dynamic, condenser, and ribbon microphone operating principles and polar patterns. Students match mic types to sources based on technical requirements.

Lesson 2 • Signal Processors: Dynamics and EQ

Introduces compressors, gates, limiters, and equalisers as tools for shaping tone and controlling dynamics. Students set parameters by ear and by meter.

Lesson 3 • Mixing Consoles and Signal Routing

Explains analogue and digital console architecture, channel strips, and bus routing. Connects console layout to the signal flow model from Chapter 1.

Lesson 4 • Power Amplifiers and Loudspeakers

Covers amplifier classes, power ratings, and loudspeaker driver types. Students calculate amplifier-to-speaker matching for safe, efficient operation.

Lesson 1 • Power Distribution and Grounding

Addresses electrical power requirements, grounding practices, and ground loop elimination. Prevents hum, equipment damage, and safety hazards on site.

Lesson 2 • System Diagrams and Documentation

Teaches students to draw and read professional signal flow and rack diagrams. Documentation skills reduce setup errors and speed troubleshooting.

Lesson 3 • Drive Rack and System Processing

Explains the role of digital signal processors in managing crossovers, delays, and limiting for speaker systems. Students configure a drive rack for a basic system.

Lesson 4 • Gain Structure and Headroom Management

Establishes optimal level-setting at each stage to maximise signal-to-noise ratio and prevent clipping. Directly applies decibel maths from Chapter 1.

Lesson 1 • Frequency Identification by Ear

Trains students to identify frequency ranges by listening, using sweep techniques. Ear training accelerates real-time mixing decisions without relying solely on meters.

Lesson 2 • System EQ and Room Tuning

Covers measurement-assisted room tuning using real-time analysers and reference microphones. Students align a system to a target curve for the venue.

Lesson 3 • Feedback Control and Prevention

Identifies the causes of acoustic feedback and applies EQ and gain management to eliminate it. Students ring out a monitor system safely and efficiently.

Lesson 4 • Channel EQ for Live Sources

Applies EQ to individual instruments and vocals to achieve mix clarity and separation. Reinforces the connection between source characteristics and corrective technique.

Lesson 1 • Gating and Noise Reduction

Applies noise gates to reduce bleed and background noise between musical phrases. Students set gate parameters to open and close cleanly without artefacts.

Lesson 2 • Compression Principles and Settings

Deepens understanding of threshold, ratio, attack, release, and knee settings. Students set compression by ear and by gain reduction meter for common live sources.

Lesson 3 • Dynamics in the Full Mix Context

Integrates dynamics processing across all channels to achieve a cohesive, controlled mix. Students balance individual channel dynamics with bus and master bus processing.

Lesson 4 • Multiband and Dynamic EQ

Introduces frequency-selective dynamic processing for complex tonal control. Students apply multiband compression to manage low-end buildup and vocal sibilance.

Lesson 1 • Soundcheck Workflow and Preparation

Establishes a systematic soundcheck sequence from line check to full-band balance. Efficient preparation reduces show delays and builds performer confidence.

Lesson 2 • Mixing for Different Genres and Venues

Adapts mixing approach to acoustic music, rock, speech, and corporate events. Students recognise how genre and venue size change every processing decision.

Lesson 3 • Effects Use in Live Mixing

Applies reverb, delay, and modulation effects to enhance live performances without muddying the mix. Students set effect parameters appropriate to the venue and genre.

Lesson 4 • Front-of-House Mix Balancing

Develops real-time mix balancing skills for frequency, dynamics, and spatial placement. Students create a clear, punchy mix that translates across the venue.

Lesson 1 • Phase and Time Alignment

Explains phase relationships between speakers and applies delay to achieve time coherence. Students align subwoofers and delay speakers using measurement data.

Lesson 2 • Optimisation Workflow and Documentation

Integrates EQ, delay, and limiting adjustments into a repeatable optimisation workflow. Students document final settings for recall and handoff to other engineers.

Lesson 3 • Acoustic Measurement Tools and Software

Introduces measurement microphones, audio interfaces, and software platforms for system analysis. Students capture accurate impulse responses and frequency plots.

Lesson 4 • Frequency Response Analysis

Reads and interprets frequency response plots to identify system deficiencies. Students distinguish room-caused anomalies from equipment-caused anomalies.

Lesson 1 • Systematic Troubleshooting Methodology

Introduces a structured divide-and-conquer approach to isolating audio faults. Students apply the method to simulated failures before working on live systems.

Lesson 2 • Networked Audio Systems

Introduces digital audio networking protocols for routing audio over Ethernet infrastructure. Students configure a basic networked audio system and verify signal flow.

Lesson 3 • Common Faults and Their Causes

Catalogues hum, buzz, distortion, dropout, and feedback causes with their diagnostic signatures. Students recognise fault types by sound and meter behaviour.

Lesson 4 • Wireless System Management

Covers frequency coordination, antenna placement, and RF troubleshooting for wireless microphones and in-ear monitors. Students deploy a multi-channel wireless rig without dropouts.
