First of all, let me tell you about the sound source. You can refer to it then and consider funds and so on.
1, I wonder what your microphone looks like, wireless? Cable TV? It's best to use wireless for evening programs.
You didn't mention the effect device above. Singers need effect devices to sing or something, otherwise the sound will be too dry. That sounds uncomfortable.
3. If possible, you can add an equalizer. If you are a professional, you will be fine. If you are unprofessional, half a bucket of water, don't take the equalizer more than half, and suddenly increase the low frequency or high intermediate frequency by one point.
4. Prepare several microphone stands, which can be used when the host speaks, without holding the microphone, like a singer.
If it is night, you should prepare some lighting equipment. Stop lights and so on are enough. Add computer lights if you have money. Use PAR lights during the day. Change the color. Increase the atmosphere.
6. Prepare an MD recorder. Such an important event should of course be recorded. Of course, the sound should be better, and the video will be recorded by then. With this audio clip,
7. If it is a wireless microphone, prepare two extra 9V batteries and plug them in. If the plug-in is not equipped with automatic overheating protection, it will jump halfway.
That's all. I hope I can help you.
