Expansion of
conference system
This page describes how to connect conference system to other system such as sound system.
Conference systems are often connected to a sound system in order to allow an audience to hear what is being said in a meeting or to make presentations at the same time. It may also be connected to a web conferencing tool.

A simple depiction of connections with other systems is shown in the diagram below.
Connection with sound system
In the example above, a conference system is connected to a mixer on the sound system side. Audio from the conference system microphone (MIC) is output from the sound system speaker (SP).
A wireless MIC is also connected to the sound system. This wireless MIC is of course output from the SP of the sound system, but it is also output from the SP of the conference system unit.
A wireless MIC is also connected to the sound system. This wireless MIC is of course output from the SP of the sound system, but it is also output from the SP of the conference system unit.

The important thing to keep in mind here is to avoid audio loops. |
Connection with sound web meeting tools
When connecting to a web meeting tool, it's basically the same, designers need to be careful about audio loops. It is necessary to prevent audio output from the web meeting tool from returning directly to the web meeting tool.

It may seem like you don't need a conference system or sound system when you have a web meeting tool, but even these have their benefits.
For example, meeting participants in a conference room (hereafter referred to as local) can only talk to local participants. If everyone participates in a web meeting, everything said will be exposed to everyone. It may also be difficult to speak at the same time in a web meeting. Additionally, if the conference is held solely through web meetings, the audience must participate in each web meeting using a PC or smartphone. If they are already local, it may be cumbersome and unnecessary. |
External Control
External controls may allow the facilitator to turn on/off the MIC, start voting, etc. It may also be linked to a camera or display.
Some external features will be introduced.

MIC Operation
The ON/OFF of the MIC may be operated by conference participants themselves using the keys on the MIC/SP unit, but may also be operated by an operator other than the participant.

This method is used when the content to be progressed in advance, such as congress, or when there are many MICs. Control is performed on a PC screen. Participants may be able to send requests for MIC ON to the control screen using the microphone unit or desktop switch. |
|
Minutes / Recording Often a recording function is required. This is because the minutes must be created. Designers need to think about how to start and stop recording, how to extract and play sound sources. In the Congress, of course, recordings are also made, but the minutes are created in real time by a stenographer. The system will need a monitor audio output function for them. |
External Audio Transmission In the case of congress, TV stations, radio stations or web channel may broadcast. In that case, an external audio transmission function is required. External transmission may pay attention to the signal transmission level. It may be different from the line level of the PA device. Even small conferencing systems may need to send audio to a remote location. When connecting to a TV conference system or web conferencing application, it is necessary to design the audio path so that loops do not occur. |

Voting
Counting the number of approvals, disagreements, abstentions, etc. from participants. These may be posted in a box, or equipment may be used.
Voting results may be private, but may be displayed in the venue if immediate results are made public.

Outputs MIC ON information from the conference system and uses it as a countdown trigger.
