Church Sound System Course

Lesson 1 • Core Components of a Sound System

Identifies microphones, mixers, amplifiers, speakers, and signal processors. Connects each component's role to overall system performance.

Lesson 2 • Signal Flow from Source to Speaker

Traces audio from a microphone through the console to loudspeakers. Understanding flow prevents troubleshooting errors later in the course.

Lesson 3 • Electrical Safety and Equipment Care

Covers grounding, shock hazards, proper power sequencing, and cable storage. Safe habits protect volunteers, clergy, and costly equipment.

Lesson 4 • Decibels and Loudness Measurement

Explains dBu, dBV, dBSPL, and dBFS scales used in worship audio. Accurate level reading underpins every mixing decision in later chapters.

Lesson 1 • Polar Patterns and Rejection

Explains cardioid, supercardioid, omnidirectional, and figure-8 patterns. Pattern choice directly controls feedback risk and ambient noise rejection.

Lesson 2 • Wireless Microphone Systems

Covers transmitter, receiver, antenna placement, and frequency coordination. Reliable wireless operation is critical for mobile clergy and worship leaders.

Lesson 3 • Lavalier and Headset Microphones

Addresses clip placement, clothing noise, and sweat protection for body-worn mics. These mics are the most common source of avoidable audio problems.

Lesson 4 • Microphone Transducer Types

Compares dynamic, condenser, and ribbon transducers by sensitivity and durability. Matching transducer type to source improves capture quality.

Lesson 1 • Routing, Buses, and Aux Sends

Explains main mix, subgroups, aux sends, and matrix outputs. Correct routing delivers the right audio to mains, monitors, and recording feeds.

Lesson 2 • Building a Balanced Worship Mix

Applies level, panning, and blend principles to a full worship service mix. A balanced mix ensures every voice and instrument is intelligible.

Lesson 3 • Gain Structure and Headroom

Establishes correct gain at every stage to maximise headroom and minimise noise. Poor gain structure is the leading cause of distortion and hum.

Lesson 4 • Digital Console Features and Scenes

Covers scene recall, channel libraries, and digital patching on modern consoles. Scene management saves setup time and ensures service-to-service consistency.

Lesson 1 • EQ for Musical Instruments

Addresses tonal shaping for piano, guitar, bass, and drums in worship bands. Instrument EQ creates separation and prevents frequency clashes in the mix.

Lesson 2 • Parametric EQ Techniques

Teaches frequency, gain, and Q controls for surgical and broad corrections. Parametric EQ is the primary tool on modern digital consoles.

Lesson 3 • EQ for Speech Intelligibility

Targets the 1–4 kHz presence range to maximise spoken-word clarity. Intelligible speech is the highest priority in any worship sound system.

Lesson 4 • Graphic EQ for System Tuning

Uses 31-band graphic EQ to correct loudspeaker and room response. Graphic EQ is commonly inserted on main outputs in worship systems.

Lesson 1 • Limiting for System Protection

Inserts limiters on amplifier inputs and main outputs to prevent damage. Hard limiting is the last line of defence for speakers and amplifiers.

Lesson 2 • Gates and Expanders

Uses noise gates to silence open microphones between spoken passages. Gates reduce ambient noise and feedback risk during quiet worship moments.

Lesson 3 • Compressing Vocals and Speech

Applies gentle compression to tame dynamic preachers and worship vocalists. Consistent vocal levels reduce operator workload during services.

Lesson 4 • Compression Principles and Controls

Explains threshold, ratio, attack, release, and makeup gain on a compressor. Understanding these controls is prerequisite to all dynamics processing.

Lesson 1 • Understanding Feedback Causes

Identifies the gain, frequency, and physical conditions that create feedback loops. Knowing root causes enables permanent fixes rather than temporary workarounds.

Lesson 2 • Ringing Out the System

Walks through the process of finding and notching feedback frequencies before services. A properly rung-out system allows higher gain without squealing.

Lesson 3 • Digital Feedback Suppression Tools

Evaluates automatic feedback suppressors and their role alongside manual EQ. These tools assist volunteer operators but cannot replace proper system setup.

Lesson 4 • Acoustic Treatment Principles

Introduces absorption, diffusion, and bass trapping for worship space acoustics. Treatment reduces reverberation and improves speech intelligibility.

Lesson 1 • Wedge Monitor Placement and EQ

Covers wedge angle, distance, and EQ to maximise gain before feedback. Properly tuned wedges reduce stage volume and improve overall mix clarity.

Lesson 2 • Troubleshooting Monitor Problems

Diagnoses no-sound, feedback, and distortion issues in monitor systems. Fast diagnosis during rehearsal prevents problems from carrying into services.

Lesson 3 • Stage Monitor Fundamentals

Explains why performers need monitors and how aux sends create separate mixes. Monitor quality directly affects worship team performance and confidence.

Lesson 4 • Building Performer-Specific Mixes

Teaches how to take mix requests and translate them into console adjustments. Meeting performer needs quickly reduces service disruption and builds trust.

Lesson 1 • Pre-Service Setup and Soundcheck

Establishes a repeatable setup checklist and soundcheck sequence for services. Consistent pre-service routines prevent the majority of live audio problems.

Lesson 2 • Operating During Worship Services

Covers real-time mixing decisions for music, prayer, preaching, and transitions. Anticipating service flow allows proactive adjustments instead of reactive fixes.

Lesson 3 • Post-Service Teardown and Maintenance

Covers proper shutdown sequence, cable coiling, and equipment logging after services. Good teardown habits extend equipment life and prepare for the next service.

Lesson 4 • Real-Time Troubleshooting Methods

Provides a systematic approach to diagnosing audio faults during live services. A calm, methodical process resolves issues faster than random adjustments.
