Pre-Event Planning

Effective management of multiple performers and complex sound requirements begins long before the audience arrives. Thorough pre-event planning is the foundation for a smooth production. This phase involves gathering detailed information from every performer, assessing the venue's acoustics, and creating a comprehensive technical plan. Start by sending out a standardized technical rider form to all performers well in advance. This form should request specific information about microphone preferences, monitor needs, instrument requirements (backline), special effects, and any unique sound considerations. Collecting this data early allows the sound team to prepare and avoid last-minute surprises.

Understanding Performer Requirements

Each performer may have distinct sound needs. Vocalists might prefer specific microphone models (e.g., Shure SM58 for durability or Neumann KMS 105 for clarity), while instrumentalists may require DI boxes for acoustic guitars or direct inputs for keyboards. Understanding whether a performer uses in-ear monitors (IEMs) or wedge monitors affects how you route the monitor mix. Additionally, consider the genre of music; a jazz ensemble will have different dynamic range needs compared to a rock band. Document all preferences in a shared spreadsheet accessible to the production team.

Creating a Detailed Run of Show

A run of show (ROS) document is essential. It should list every performance segment, including the order of acts, stage positions, sound cue times, and any special instructions. Include accurate timings for setup, performance, and teardown. Share the ROS with all performers and crew at least 48 hours before the event. For large multi-act events like festivals or conferences, consider using a digital platform to keep the schedule in real-time sync. Reference resources like the ProSoundWeb for templates on creating effective run-of-show documents.

Communication Protocols

Establish clear communication channels among the production team. Use headsets or intercom systems for the sound engineer, stage manager, and lighting operator. Performers should have a direct line to the stage manager via hand signals or a dedicated talkback microphone. Conduct a technical rehearsal (soundcheck) where each performer works with the engineer to dial in their monitor mix and front-of-house levels. This is also the time to discuss stage positioning and potential issues. Ensure that all crew members know the plan for emergency scenarios like equipment failure or performer changes.

Sound Equipment Management

Proper sound equipment management is critical when juggling multiple performers. The goal is to create a flexible, reliable system that can be adapted quickly. Start by auditing your inventory: ensure you have enough microphone channels, DI boxes, stands, and cables. Label every cable and input on the stage box with the performer's name and instrument. Use a color-coding system for patching to reduce confusion during changes. Consider using a digital mixing console (e.g., Yamaha CL series or Allen & Heath SQ) because they allow storing scene presets for different acts, enabling rapid transitions between setups.

Microphone Selection and Placement

Choose microphones based on the application. For vocalists, go with dynamic mics for loud stages or condenser mics for quieter, more articulate settings. Instrument mics vary: SM57 for guitar amps, e604 for toms, and D112 for kick drums. Place microphones carefully to minimize bleed and phase issues. Use isolation shields if necessary. For multiple performers sharing a stage, consider using wireless microphones and wireless IEM systems to reduce cable clutter and allow performers freedom of movement. However, be mindful of radio frequency coordination to avoid interference. The Shure Wireless Workbench is a useful tool for this.

Mixing Console Configuration

Configure your mixing desk to handle multiple input sources and scenes. For digital consoles, create a scene for each performer or group. Store individual input gain, EQ, dynamics, and send levels. Use assignable fader layers to quickly access key channels for each act. Assign compressor and gate presets per channel to maintain consistency. Ensure that main outputs (left/right, subwoofers) are locked to avoid accidental changes. For analog consoles, create a patchbay layout that allows easy repatching during changeovers. Always have a backup console or a tablet remote (e.g., for mixers like the Behringer X32) for troubleshooting.

Monitoring Systems and In-Ear Monitors

Monitor mixing is often where the biggest challenges arise with multiple performers. Each artist may want a different mix of vocals and instruments in their monitors. Use auxiliary sends to create separate monitor mixes. If using IEMs, invest in a digital wireless IEM system for low-latency and clear audio. For wedge monitors, ensure proper placement to avoid feedback. During soundcheck, use the "mix minus" technique: the monitor mix for each performer should contain all sources except their own, to reduce confusion. A dedicated monitor engineer can handle this while the front-of-house engineer focuses on the audience. Resources like Audio-Technica offer detailed guides on monitor setup.

Managing Multiple Performers on Stage

The physical flow of performers on and off stage can make or break an event. Overcrowding leads to missed cues and degraded sound. Plan staging with clear access routes. Use a stage plot to indicate exactly where each performer will stand and where their equipment will be placed. Stagger entrances and exits to avoid bottlenecks. Assign a stage manager to coordinate these movements using headsets or visual signals (e.g., wireless light cues). For quick changeovers, have dedicated side-stage areas with pre-patched equipment ready to go.

Stage Plot and Input List

Require each performer to submit a stage plot and input list before the event. The stage plot shows the physical position of musicians, amplifiers, and monitors. The input list details every microphone and DI needed, including channel numbers and any special processing. Use these documents to pre-label your stage box and set up the console layout. This is especially important for multi-band events where multiple setups must be loaded in and out quickly. Templates are available from Sound On Sound.

Cue Systems and Communication

Establish a reliable cue system that works even with loud stage volume. Visual cues like LED signs or colored lights can signal performers to start or stop. For more complex cues (e.g., during musical numbers where sound effects are synchronized), use timecode or a click track fed to all performers via IEMs. Verbal cues through a stage talkback mic should be available in each monitor mix as needed. Consistency is key: rehearse all transitions during the technical rehearsal.

Handling Quick Changeovers

When events have back-to-back acts, changeover time is precious. Not only must performers swap, but sound equipment might need re-patching. Create a "fly" system: use subsnakes for each act's inputs and swap them at the stage box. For digital consoles, recall a scene that already has the inputs assigned and processed. Have a dedicated crew member for each major equipment group (mics, cables, stands). Use a timer and a checklist to ensure nothing is missed. The goal is to keep downtime under five minutes for large events.

During the Event: Monitoring and Adjustments

Once the event starts, the sound engineer's role shifts to real-time management. Continuously monitor sound levels and quality through headphones and the main PA. Watch the stage for performer cues (e.g., hand gestures indicating they need more vocals in their monitor). Use the console's metering to detect clipping or feedback. Have a clear plan for emergencies: if a microphone fails, rapidly swap with a backup placed on a spare channel. Keep a "cue stack" of prepared changes for different sections of the performance.

Real-Time Audio Monitoring

Use a reference microphone placed in the audience area to gauge the overall sound. Compare the mix on solo buses for each performer. For live streaming or recording, ensure separate mixes are sent to the broadcast console or recording device. Many digital consoles allow multi-track recording to USB or Dante, which can be used for post-event adjustments or archival. For large events, consider having a second engineer dedicated solely to monitor mixing or recording.

Dealing with Feedback and Noise

Feedback is a common challenge with multiple microphones on stage. Use narrow notch filters on graphic equalizers to reduce feedback frequencies without affecting overall tone. Train the monitor engineer to quickly identify feedback by ear and suppress it. Use feedback suppression devices like the dbx AFS2 for automatic notching. Also, manage stage volume: excessive instrument volume from amplifiers can bleed into vocal mics. Encourage performers to use amp simulation (modelers) or isolation cabinets to reduce bleed. If noise from lighting dimmers or power supplies enters the audio system, use balanced cables, ferrite chokes, and proper grounding to eliminate hum.

Recording vs Live Considerations

If the event is also being recorded, the sound needs may differ. A live mix focuses on audience experience, while a recording requires a cleaner, more isolated sound. Use digital splits to send the same microphones to two independent mixers: one for front-of-house and one for recording. Alternatively, use a splitter snake. Gain staging must be set so that both mixes have adequate headroom. For live broadcasts, coordinate with the broadcast engineer to deliver a mix that fits their requirements—often a separate stereo or surround feed.

Post-Event Review

After the event, gather feedback from performers and crew to improve future productions. Review the sound engineer's notes and any issues encountered. Analyze multitrack recordings to identify mix problems or equipment malfunctions. This data helps refine pre-event planning and equipment choices. Document what worked and what did not in a shared production report.

Gathering Feedback from Performers

Send a short questionnaire to each performer asking about their monitor mix clarity, stage comfort, and any sound issues. Use this feedback to adjust your workflows. For example, if multiple performers complained about feedback during certain sections, consider repositioning monitors or changing microphone polar patterns.

Documenting Lessons Learned

Maintain a production library with templates for stage plots, input lists, and run-of-show per venue. Note any venue-specific acoustic quirks and preferred equipment settings. This institutional knowledge saves time for future events and helps new crew members get up to speed quickly. Share successful techniques with colleagues on platforms like the ProSoundWeb forums or specialized Facebook groups.

By following these best practices—thorough pre-event planning, meticulous equipment management, structured performer coordination, real-time monitoring, and post-event review—event organizers and sound engineers can confidently manage multiple performers and complex sound requirements. The result is a seamless, professional production that delights audiences and respects the art of the performers.
