Conference Microphone Systems: The Ultimate Guide

If you are looking for conference microphone systems (also known as push-to-talk mic, discussion or conferencing systems) and are not sure where to start, you’ve come to the right place. We know this can be a tricky subject, so we’ve put all the necessary information on one page.

The most common applications for conference microphone systems are:

• Board rooms
• Focus groups
• School boards and PTAs
• Conference and meeting facilities
• Classrooms and educational seminars
• Parliamentary and government settings

In plain English, conference mic systems are a type of audio equipment that enable meeting participants to hear and be heard by each other.

Imagine a 20-member city council sitting around a table, with an additional 100 audience members watching. With a group of this size, it is impractical to pass a microphone between speakers. It would slow things down to the point of chaos.

That’s where the conference mic system comes in.

In a typical conferencing setup, each participant has a personal (gooseneck style) microphone unit. This  lets them speak to the other attendees and listen to others through a small speaker. The chairman of the meeting has a special unit with controls for volume, mute (to recognize speakers or cut off those whose time has expired), voting features, and so on.

The ultimate goal of conference microphone systems is to bring the efficiency of a small meeting to a larger setting.

Why You Need A Conference Microphone System For Your Meetings

Accessibility: Makes it easy for a wider group of speakers to participate in the meeting and allows a larger audience to follow the proceedings (either as passive listeners or after the fact via recordings).

Saves Meeting Time: Eliminates the need for speakers to constantly trade microphones, as each speaker has a personal mic. This stops needless time wasted fumbling with microphones between speakers, (or awkwardly trying to get a mic back from a speaker who has gone on too long). It is always clear who is speaking because each microphone has a light that illuminates when on.

Enables Language Interpretation: With multi-lingual groups, conference microphone systems are often used with simultaneous interpretation equipment. The individual mics allow the floor feed to be sent directly to the interpreter, so that he/she has a clear audio signal to translate.

Improves Meeting Flow: The system’s mute, volume and voting controls allow the Chairman to discreetly control the meeting, recognize participants, and call to order as necessary.

Aesthetics: The sleek and polished appearance of the systems signals professionalism and respect for all participants. By giving each speaker a personal microphone, it also shows a commitment to valuing each person’s voice.

Key Terms for Understanding Conference Microphone Systems

A few pieces of lingo are essential to understanding these systems:

Chairman / Chairman Unit:

This is the person running the meeting. He/she can recognize speakers,alert them when their time is up, and organize voting. For this reason, the chairman has a special mic called the Chairman Unit with  additional features like muting speaker priority to direct the discussion. These push-button features are simple to use and help the speakers focus on working with the group.

Delegate / Delegate Unit: Refers to all other participants in the meeting who are not the chairman. The delegates each have their own microphone, called a Delegate Unit. These units typically have a push-to-talk button, volume control, voting buttons (optional), and a light that illuminates when the mic is live.

Central Control Unit (CCU): This is the central piece of equipment that controls (and powers, if wired) all the individual microphone units. It also mixes the mic feeds, distributes target language feeds, and powers the voting functionality. Some central units also feature built-in recording capability.

Floor Language: The main language spoken by participants at a given time.

Target Language(s): The language in which each delegate hears the speech. It can also be called the translation feed. When the audience is diverse enough to need multiple target languages, this can be provided through multiple interpreters using the same system. The rest of the interpreting process remains exactly the same.

Simultaneous Interpretation: A type of translation where the interpreter listens to the floor feed through headphones while translating orally to the target language in real time. This is a highly demanding job. The interpreter must listen, mentally translate, and speak their translation all at once, with no time to check outside resources. For more information, see our resource page on translation equipment.

Factors to Consider when Purchasing a Conference Microphone System

Ease Of Use: These systems aim to increase the efficiency of your meeting so the equipment must be easy for participants to use. No use investing in the equipment if participants can’t use it! So it is critical for the controls (volume, push to talk, on/off light) to be instantly understood by users.

Number of Participants: The number of users must be known to select the right number of delegate mic units. Most CCUs can accommodate 80-120 delegate units, so in cases of very large groups, the number of users can affect the number of central control units needed.

Sound and Signal Quality: Older model systems use an analog audio signal, but most modern systems have gone digital for increased audio quality, lighter weight, and more signal processing and recording options.

Venue: Your event location will determine if you need a wired or wireless system.  If you are using infrared interpretation gear, it’s also important to maintain a line of sight between the transmitter and the receiver, as IR signals cannot penetrate walls. Other audio equipment (eg recording equipment) that you are using on site can also play a role in this decision.

Advanced Features: Conference Microphone systems are becoming more advanced with special features, so consider whether you will need:

• Voting and Parliamentary Procedure Functions: for example keeping track of historical votes, support for more complex voting processes, etc.
• Recording Capabilities: Some units have built-in digital recording so that you can preserve the proceedings for review later, publication, etc.
• Videoconferencing: Some conferencing systems are made to integrate with cameras for video conferences. Is this something you need, or would like to keep the option of this integration in the future?

The Two Types of Conference Microphone Systems: Wired and Wireless

We partner with Listen Technologies to offer the highest quality systems on the market. The systems we offer come in two flavors: wireless and wired. Here’s an overview of the two systems:

Wired Conference Mic Systems

Key Points

• Encourages participation by giving all participants a right and ability to speak and be heard.
• Wired digital systems are ideal for settings where equipment is set-up once and infrequently moved such as hotel conference rooms, political or board meetings, gyms, libraries, and etc.
• Built-in audio recording capabilities for future playback or publication – simply plug in an external USB stick and select your desired format.
• Each Delegate Unit has its own push-to-talk button, enabling participants to simply press their button to be heard by the audience. There is also a voice activation mode, so participants do not have to press a button to be amplified.
• Each Central Control Unit can power up to 50 Delegate Units.  Can be expanded to support 1,024 conference mic units with up to 8 simultaneous open mics.
• For language translation applications, the system supports four languages. Expandable to support up to 28 languages through additional licenses.
• System is designed to resist interference (ie, that annoying buzz) caused by mobile interference.
• When active, each microphone unit features a red lighted ring for increased visibility. This light is bright enough to be picked up on camera for TV broadcast.
• Delegate and Chairman Units connect to CCU via digital Cat6 cables.
• Digital technology produces clearest audio quality possible. The digital process reduces feedback and units are fanless, so they eliminate background noise.
• Delegate units can be shared between two people to help keep the cost down if necessary.
• Participants can use built-in headphone connection for hearing assist.

Setup, Operation and Maintenance
The system is extremely easy to set up and use. A digital CAT5 cable carries signals between the CCU and the mic units. Delegates press a button to begin speaking, and a light appears for the chairman and the delegate to show the delegate’s desired to talk. Chairman Unit includes a button to allow discussion, granting permission for a delegate to speak to the group. Ongoing maintenance of devices is minimal; and they are simple to clean.

Technical Notes

• A CAT5 cable is used to connect the conference microphone system units together. The cable must be shielded to prevent interference.
• Maximum cable length between units is 260 ft. and 1,300 feet for any branch connection.
• System contains multiple input and output connectors for connecting to additional AV equipment or teleconferencing systems.
• Save your recordings in a variety of quality levels and formats: either .wav or mp3 and 64, 128, or 192 kbps.

What is a video conferencing service? 

Video conferencing services help you meet and collaborate with others via an HD video feed. Unlike a call, video conferencing lets you see meeting participants, almost as if you were in the same room.  

Professionals can access video conferencing services from various devices, including internet-connected computers and personal or business smartphones. You can also set up video conferencing in a specific location, like a conference room. With this option, you can set up cameras to show the entire room and use microphones to amplify speakers. 

Video conferencing services give hosts total meeting control. Hosts decide who can talk, who can be on video and who can share their screen. For example, if someone attending the meeting is giving a business presentation, the host can allow screen sharing so everyone can view the PowerPoint presentation. 

For invitees who are unable to attend a meeting via video, many services offer the option to join by . 

Did You Know?Did you knowIn a pinch, you can use an iPhone for conference calls. While you're limited to five participants on audio calls, you can use the FaceTime app for up to 32 people.

How do you choose the right video conferencing service?

Take the following steps to determine the right video conferencing service for your business.

1. Consider your video conferencing needs.

Do you need video conferencing software for short one-on-one meetings, or will you use it for more extended client or vendor meetings? Your answer to this question can help you decide whether to accept a lower-cost platform with shorter meeting time limits and fewer advanced features. Other considerations, such as whether you’ll need screen-sharing or webinar features, can also help you narrow your choices.

2. Research the market for video conferencing services.

A few brands might immediately come to mind when you think of video conferencing services. However, big-name brands aren’t your only options, and other platforms may suit your needs better. 

Researching the video conferencing market can yield unique solutions that may be right for your organization. For example, some platforms may be superior for one-click meeting access, while others may seamlessly integrate video conferencing with meeting-notes technology.

3. Compare video conferencing contenders’ video quality.

A video conferencing platform with all the features you could ask for means little if the video is low-quality. Some prominent video conferencing platforms offer paid plans with a quality of 720p, which is on the high end. Consider prioritizing these platforms in your decision-making process.

4. Review video conferencing contenders’ integrations.

A video conferencing service that integrates with your other software platforms will be easier to use across the board. For example, some video conferencing services integrate with the best online project management platforms and the best HR software to streamline communication. Consider how the integrations available for each potential platform might put it a step above the others.

5. Weigh video conferencing solutions’ prices against features.

Ask yourself whether a video conferencing platform’s price justifies its included features. Better yet, ask how this price compares with those of other platforms and their offerings. Your goal should be to balance your budgetary concerns with the features you need from your video conferencing platform.

6. Read customer reviews of various video conferencing services.

Video conferencing services’ official websites can only tell you so much; after all, they’re designed to paint the platform in a flattering light. Customer reviews may give you a more honest perspective because most reviewers have no incentive to share falsely positive commentary. 

Look at whether most reviews say the product is worth its price, name any notable flaws or speak to the brand’s customer service. If negative customer reviews give you pause, read another brand’s reviews. They may be more positive, giving you a superior option.

7. Explore a video conferencing product demo or free trial.

Many video conferencing brands offer a product demo or free trial for a hands-on experience with the platform. This may be the best way to assess whether a video conferencing service fits your needs. You’ll get to use the platform without committing to it, and sales and customer service reps will be readily available to answer any questions. After trying a few products, you might instinctively know which one would serve you best.
