Event Spaces and the Compromise Between Concert and Conference: How to Design a System for Three Different Event Types

An event space has incompatible requirements by definition. On Tuesday it hosts a corporate conference, on Saturday a wedding, and two weeks later a concert by a local band. Each of these events requires something different from the sound system, and all of them take place in the same room with the same technology.

The investor or operator usually recognizes this only when complaints start coming in.

• A conference client says the speaker could not be heard.
• Wedding guests say the music was too quiet in the corners of the hall.
• The band says the system has no dynamics.

Each of these complaints comes from the same source, and a system that was not designed as multi-mode behaves like a compromise.

This guide explains why “universal sound reinforcement” does not work in an event space and why the decision about event AV is made at the level of signal architecture, not loudspeakers.

Three scenarios, three technical profiles

Corporate event and conference

The primary content is spoken word. A speaker stands at the front of the hall with a presentation on screen, the audience sits in rows, and the last row must have the same intelligibility as the first. In hybrid mode, a Teams or Zoom connection is added, and it must work both ways.

Technical requirements:

• high speech intelligibility (STI above 0.70),
• medium sound pressure level,
• even coverage across the hall,
• microphones for the speaker and for audience Q&A,
• AEC (Acoustic Echo Cancellation) for hybrid mode.

Subwoofers are not needed in this mode, but if they are part of the system, they must be switchable off.

Wedding or private celebration

Music with speeches. Part of the evening is atmospheric, part of it is dance-oriented. A speaker takes a microphone and speaks from a table or near the DJ booth. Speeches are spontaneous and are not always addressed to the entire hall.

Technical requirements:

• medium to higher dynamics,
• microphones available in different locations, typically 2-4 wireless handheld microphones,
• music with sub-bass presence for dancing,
• even coverage also in the corners of the hall,
• simple control for the DJ or wedding technician.

Concert and cultural event

Music is the primary content. Performers are on stage, sound pressure is high, dynamics range from silence to fortissimo, performers need monitoring so they can hear themselves, and an external sound engineer works from a mixing position in the hall.

Technical requirements:

• high sound pressure level, often 100+ dB SPL peak,
• wide frequency response including sub-bass,
• separate monitoring for the stage and for the audience,
• multiple microphone inputs, typically 8-16,
• connection points for external equipment.

These three profiles differ in almost everything. Sound pressure, number of microphones, microphone placement and whether there is an external sound engineer in the hall. The design decision is this:

One system with three configurations, or three compromises in one system.

Why universal sound reinforcement does not work

A technical specification for an event space often contains a requirement such as “high-quality sound system for different types of events”. This is not a specification. It is a wish, because apparently even procurement documents enjoy vague poetry.

With such a brief, the supplier designs a system that is a compromise between all modes. And we all know what compromise means. It does not work optimally in any of them.

A system optimized for concerts has high sound pressure and sub-bass, but during a conference with low occupancy it sounds harsh and speech becomes overloaded. A system optimized for conferences has ceiling-distributed loudspeakers for even coverage, but at a concert it has no dynamics and lacks bass response.

The solution is to give the system different DSP configurations for different modes, with hardware dimensioned to handle the highest requirement across all use cases. Optimization happens through software, not through hardware.

Presets as the core of flexibility

The solution for a multi-mode space lies in the DSP processor (Digital Signal Processor) and in prepared presets for each event type.

A preset is a saved configuration that defines how the signal behaves in a specific mode. Which loudspeakers are active, at what level, with what equalization, how microphones are routed, and whether subwoofers are switched on.

A typical event space has 3-5 presets:

• Conference mode – distributed hall coverage, subwoofers off or at minimum level, EQ optimized for speech, AEC enabled for hybrid meetings.
• Wedding mode – full hall coverage with sub-bass presence, microphones for speeches with fast routing, music channel with DJ connection.
• Concert mode – full sound pressure, monitoring setup for the stage, inputs for an external mix.
• Atmosphere mode – background music for refreshments, cocktail parties or networking parts of an event.
• Quiet mode – system switched off or minimal operation for small-group training sessions.

The preset is switched with one touch from the control panel. Staff or an external technician do not need to configure individual parameters. The mode is moved into a prepared state, and from there only the extra requirements of the specific client are adjusted.

The key difference compared with a system without presets is that each mode change takes one second, not half an hour of tuning. In an event space where different event types rotate throughout the week, this is the difference between a system that is actually used and a system that needs a technician to retune it before every event.

Microphones and guest equipment

The second layer of flexibility is the microphone and input architecture. This is where it is decided whether the space can also handle events that were not anticipated during the original design.

Microphone setup

For an event space, this typically includes a combination of wired and wireless microphones, and possibly ceiling beamforming microphones for conference mode.

In larger spaces, frequency planning for wireless microphones must also be addressed. Once 6-8 or more wireless channels are used, frequencies must be coordinated so they do not overlap, especially when external technicians also bring their own wireless equipment into the hall.

Patch panels and connection points

These allow a guest technician to connect their own equipment to the venue system. A sound engineer arriving with a band for a concert brings their own mixing console and microphones, but still needs a place to connect to the main loudspeakers in the hall.

A patch panel on stage and in the control room enables this connection without the technician having to understand the full architecture of the space. Without patch panels, every guest technician must be trained on the system, which in practice means that the venue is unusable for external productions.

Two mixing consoles

A fixed console in the control room and a portable one in the hall are standard in a professional event space. The fixed console is used for events operated by hotel or venue staff, while the portable console is used by external technicians who need to mix directly from the place where the audience is seated.

Interpreter booths

These are important for congresses and international conferences. They integrate with the main system through separate channels. Interpreters receive signal from the main microphones and transmit on separate frequencies, which participants listen to through headphones. When designing an event space, the decision is whether booths will be handled as a permanent installation or as a mobile solution for selected events.
