Introduction to System Checklists

A thorough live sound checklist prevents the embarrassing and career-damaging failures that can occur when basic setup or verification steps are forgotten. Professional audio engineers develop systematic approaches to system deployment and operation, catching potential problems before they affect the audience experience. This comprehensive checklist covers the complete lifecycle of a live sound production from initial setup through post-show strike and storage.

Every item on these checklists exists because someone, somewhere, forgot that step and experienced a catastrophic failure at the worst possible moment. Building these procedures into muscle memory through consistent application ensures reliable performance regardless of the production's scale or complexity. The goal is to identify and resolve problems during setup and sound check, leaving the show itself to run smoothly without surprises.

Pre-Show Preparation

Proper pre-show preparation begins days before the actual event, with equipment staging, system design review, and logistics coordination.

📋 Equipment and Logistics

  • Review venue requirements and system rider specifications
  • Confirm PA system type, coverage requirements, and power needs
  • Verify backline requirements with artist management
  • Confirm microphone list, DIs, and stage box requirements
  • Arrange equipment transport and confirm vehicle capacity
  • Pack redundant cables, fuses, and common failure items
  • Bring necessary tools: multimeter, cable tester, soldering iron
  • Pack gaffer tape, velcro ties, and cable management supplies
  • Confirm wireless frequency coordination if using wireless systems
  • Print stage plots, input lists, and show paperwork

📋 System Installation

  • Position main PA speakers according to coverage design
  • Fly or stack subwoofers according to system configuration
  • Aim and focus main speakers for even coverage
  • Position front fills for front-row coverage
  • Install monitor system speakers on stage
  • Run all speaker cables with proper strain relief
  • Connect amplifier outputs to speaker inputs
  • Verify amplifier power is OFF before connections
  • Run all signal cables from stage to FOH position
  • Label all cables and connections clearly

Sound Check Procedures

Systematic sound check verifies every aspect of the audio system before the audience arrives. Problems discovered during sound check can be addressed; problems discovered during the show cannot.

📋 Signal Path Verification

  • Power on mixing console and allow warm-up
  • Verify console master outputs are muted or at minimum
  • Power on amplifiers in sequence (wait between each)
  • Verify all input channels are assigned correctly
  • Test each input channel individually for signal presence
  • Check phase and polarity on all microphone inputs
  • Verify gain structure on each channel (proper headroom)
  • Test all aux sends and monitor feeds
  • Verify all effects processors are connected and functional
  • Test talkback system between FOH and stage

📋 PA System Verification

  • Play reference material at moderate level
  • Walk the coverage area listening for anomalies
  • Check each speaker zone for proper operation
  • Verify subwoofer integration with main PA
  • Adjust EQ and processing for venue acoustics
  • Set and verify compressor/limiter settings
  • Test system limiter for proper threshold and release
  • Verify output levels match expected SPL targets
  • Check delay system if used for speaker alignment
  • Confirm DSP presets are appropriate for configuration

📋 Monitor System Check

  • Test each monitor mix individually
  • Verify wedge monitor levels and EQ
  • Check all wireless IEM bodypacks and earpieces
  • Test all wireless microphone handheld andbodypack transmitters
  • Verify stage communication (intercom, cue wedges)
  • Confirm monitor engineer has appropriate mix capabilities
  • Check stage volume levels for singer comfort
  • Test direct inject boxes for instrument inputs
  • Verify click track and playback systems if used
  • Confirm all stage signal paths are functioning

During the Show

Vigilant operation during the performance maintains consistent sound quality and addresses any issues that arise before they become audience-impacting problems.

📋 FOH Operation

  • Monitor overall system headroom and limiters
  • Watch for feedback and address immediately if detected
  • Maintain consistent mix balance throughout performance
  • Respond to artist requests promptly and professionally
  • Monitor wireless systems for battery life and signal strength
  • Watch console meters for unexpected level changes
  • Maintain communication with stage monitor engineer
  • Document any issues for post-show reference
  • Be prepared for last-minute set list changes
  • Keep console clear of unnecessary items

Post-Show Procedures

Proper post-show procedures protect expensive equipment, prepare for future shows, and document lessons learned.

📋 Equipment Strike and Storage

  • Power down amplifiers BEFORE disconnecting cables
  • Allow amplifiers to cool before packing
  • Coil cables properly (over-under technique)
  • Inspect cables for damage during the event
  • Pack equipment systematically in road cases
  • Secure loose connectors and controls
  • Transport equipment to storage location
  • Clean console and work surfaces
  • Restock consumables (gaff tape, batteries, etc.)
  • Document any equipment requiring repair

Troubleshooting Quick Reference

Quick diagnosis of common problems prevents extended downtime during critical moments.

No sound from a channel: Check signal present indicator, swap cables to isolate problem, verify channel isn't muted, test direct out if available, check patchbay connections.

Hum or buzz: Check for ground loops (lift grounds selectively), verify cable shielding, ensure balanced connections throughout, check for proximity to power cables or transformers.

Feedback: Identify which channel is feeding back (usually microphones near monitors), reduce gain on that channel, reposition microphone or monitor, check EQ for resonances, reduce monitor level to that microphone.

Wireless dropouts: Check antenna positioning and connection, verify frequency isn't conflicting with other sources, replace batteries, check for body-blocking of transmitter antenna, verify receiver antenna coverage.
