How Many Microphones Do You Need for an Event?

One of the easiest parts of event audio to underestimate is the number of microphones you actually need. An event coordinator might know that there will be speeches, presentations or a panel discussion, but the question is whether one microphone is enough, whether several are required, and whether those microphones should be wired or wireless.

The answer depends on the format of the event rather than simply the number of guests. A wedding with one MC and a few speakers has different requirements from a conference with several presenters and a panel. A party where the microphone is only used occasionally may need a completely different setup from an event where several people will be speaking throughout the day.

The best approach is to work out who needs to speak, how they will speak and how the microphone will be used before deciding what equipment to hire.

How many microphones do you need?

For a simple event with one person speaking at a time, one microphone may be all you need. This is common for an MC, wedding speeches, announcements, presentations and smaller functions.

If several people need to speak at the same time, however, you may need multiple microphones. A panel discussion is a good example. If there are four panellists and a moderator, you should generally plan around five people needing access to microphones rather than assuming one microphone can simply be passed around.

The running order matters too. If several speakers are taking turns but never need to speak simultaneously, you may be able to use fewer microphones. If several people need to be ready to speak without passing equipment around, having additional microphones can make the event much easier to manage.

Start with the event format

Before choosing microphones, look at what is actually happening during the event.

A straightforward presentation might have one presenter and therefore only require one microphone. A corporate conference could have an MC, several presenters and a panel discussion. A wedding might have an MC, speeches from several members of the wedding party and announcements throughout the reception.

The same principle applies to community events, awards ceremonies, school functions and parties. Rather than choosing microphones based on the number of guests, count the people who actually need to speak and consider whether they will need to speak at the same time.

Audio Hire’s Hire by Event Type⁠ guide provides more specific guidance for weddings, corporate events, presentations and other common event formats.

One microphone for speeches and announcements

If one person is speaking at a time, a single handheld microphone can be a very practical solution.

For a fixed speaking position, the Shure PGA48 Microphone⁠ is designed for clear speech and is suited to wedding speeches, MC duties, presentations, conferences, quiz nights and announcements. It is a wired microphone supplied with a microphone clip and six-metre XLR cable.

A wired microphone is particularly straightforward when the person speaking will remain in one area. It avoids batteries and wireless transmission, and the microphone simply connects to the PA system with its cable.

If the microphone needs to remain in a fixed position while the speaker’s hands are free, a Microphone Stand⁠ can also be added.

When should you use a wireless microphone?

Wireless microphones become useful when the person speaking needs to move around.

An MC walking around a room, a presenter moving between a lectern and screen, or someone making announcements from different parts of a venue can be restricted by a microphone cable. In these situations, the Shure BLX24/SM58 Wireless Hand Held Microphone System⁠ provides a wireless handheld option.

Wireless is not automatically better than wired. If someone is standing at a lectern or fixed speaking position, a wired microphone may be the simpler choice. Wireless becomes valuable when freedom of movement is part of the requirement.

How many microphones do you need for a wedding?

Wedding audio often involves several different people speaking, but they don’t necessarily need separate microphones throughout the entire event.

A typical reception might have an MC and several people giving speeches. If only one person speaks at a time, a single handheld microphone can be passed between speakers.

The Shure PGA48 Microphone⁠ is a straightforward wired option for speeches and announcements. If the microphone needs to move around the room with the MC or be passed between speakers without dealing with a cable, the Shure BLX24/SM58 Wireless Hand Held Microphone System⁠ provides greater freedom.

Ceremonies can have different requirements again. A celebrant, readings and other spoken parts of the ceremony may require a microphone, particularly when the audience is spread across a larger area.

How many microphones do you need for a corporate event?

Corporate events can require more careful microphone planning because the format can change throughout the day.

A presentation with one speaker may only require one microphone. An event with an MC, several presenters and audience questions may need additional microphones. A panel discussion can require a microphone for every panellist as well as the moderator.

It is worth looking at the entire running order before booking. If there is a panel session, count every person who will need to speak. If audience members will be asking questions, decide whether they will use a dedicated microphone or whether a handheld microphone will be passed around.

The Corporate Events & Conferences⁠ section of the Audio Hire event guide covers these situations in more detail.

Panel discussions need more planning

Panel discussions are one of the easiest event formats to underestimate.

If several people are sitting on stage and need to contribute to the conversation, each panellist generally needs access to a microphone. The moderator or MC should also be included in the count.

For example, a panel with four panellists and one moderator has five people who may need microphones. That doesn’t necessarily mean you need five microphones for the entire event, but you should plan the panel itself around five microphone positions.

The number of microphones also affects the mixer. If you’re connecting several microphones at the same time, the sound system needs enough available inputs to accommodate them.

Do you need a microphone for the MC?

If an MC is responsible for introducing speakers, making announcements, managing games or keeping the event moving, having a dedicated microphone available can make the event much easier to manage.

A wireless microphone is particularly useful for an MC because they may need to move around the room rather than remain behind a lectern.

The Shure BLX24/SM58 Wireless Hand Held Microphone System⁠ is designed for situations where the speaker needs freedom to move. For a fixed position, the Shure PGA48⁠ provides a straightforward wired alternative.

What microphone is best for live music?

Live music is a little different from speeches because the microphone may need to reproduce vocals rather than simply spoken word.

The Shure SM58 Microphone⁠ is a professional dynamic vocal microphone suited to singers, performers and live applications.

A solo performer might only need one vocal microphone, while a band can require several microphones depending on the number of vocalists and instruments being amplified through the PA.

If several microphones are required for a live performance, the number of available mixer inputs becomes important as well. Make sure the sound system can accommodate all of the microphones and other audio sources before booking.

Do you need microphone stands?

That depends on how the microphone will be used.

A handheld microphone is generally held by the speaker, MC or performer. A stand can be useful when the microphone needs to remain in a fixed position while leaving the speaker’s hands free.

For example, a presenter might use a microphone while referring to notes or presentation material. A musician may need both hands available for an instrument. A Microphone Stand⁠ can be added for these applications.

For a lectern presentation, the microphone arrangement should also be considered alongside the position of the presenter and any presentation equipment.

Do you need a mixer for multiple microphones?

If you’re using more than one microphone, you need to consider how those microphones will connect to the PA system.

A mixer allows multiple audio sources to be connected and controlled before the signal is sent to the speakers. The Yamaha MG06 Audio Mixer⁠ is a compact option for smaller setups and provides up to two microphone inputs alongside additional line inputs.

If your event involves several microphones, music and other audio sources, make sure the mixer has enough appropriate inputs. A simple presentation is very different from a conference panel or live band.

If you’re unsure how many inputs you need, provide the full event running order rather than simply asking for a certain number of microphones. That makes it easier to work out the complete audio setup.

Wired or wireless microphones?

There is no universal winner between wired and wireless microphones.

A wired microphone is simple, reliable and particularly practical when the speaker remains in one location. The Shure PGA48 is a good example of this type of microphone for speeches and presentations.

Wireless microphones are more useful when movement is important. An MC walking around a reception, a presenter moving around a stage or a speaker who needs to interact with the audience can benefit from not being connected to the PA by a microphone cable.

The right choice therefore depends on how the microphone will actually be used.

Don’t forget the PA system

A microphone on its own doesn’t make a speaker’s voice louder for the audience. It needs to be connected to a suitable PA system or other amplification equipment.

If you’re hiring microphones for an event, make sure you know what the microphones will connect to. If the venue already has a suitable sound system, you may only need additional microphones. If you are starting from scratch, you’ll need to consider the speakers, microphones and any mixer or other equipment required to connect everything.

Audio Hire’s PA Hire Adelaide⁠ options can be combined with microphones and other equipment depending on the requirements of the event.

How many microphones should an event coordinator hire?

Start by counting the people who need to speak, rather than counting the guests.

For a simple event with one speaker or MC at a time, one microphone may be enough. For an event with several presenters, consider whether microphones need to be available simultaneously. For a panel discussion, count the moderator and every panellist. For live music, count the vocalists and any instruments that need to be amplified.

Then decide whether those people need to move around. If they do, wireless microphones may be the better option. If they remain in fixed positions, wired microphones can provide a straightforward solution.

Finally, consider the PA and mixer. Having the correct number of microphones is only useful if the rest of the sound system can accommodate them.

What information should you provide when booking?

When arranging microphone hire, give the audio hire company as much information about the event format as possible.

Tell them the venue, approximate audience size and type of event. Explain how many presenters, speakers, panellists, MCs or performers will be involved, whether anyone needs to move around, and whether the event includes music, presentations or live performance.

It is particularly useful to provide a running order for corporate events and conferences. This can reveal that you need several microphones for one part of the event but only one for another.

You don’t need to know which microphone model you need before making an enquiry. The important information is how many people need to speak and how they will use the microphones.
