If you manage conferences, trade shows, conventions or classroom training you should really consider using a microphone and amplifier. They are low cost to rent and easy to use and make even the tiniest voices heard.
When your conference or convention event grows, consider even larger audio visual solutions. Larger sound systems with speakers that match the room and audience size is best achieved with the advice of a Tech Travel Agent.
Wireless Lavalier Microphones
A wireless microphone is an the best solution. The presenter wears a small microphone on the lapel area (just clips on) that is connected to a transmitter (usually clips to a belt or pocket).
The Lavalier combines the microphone with the transmitter. Connect to your sound system via the the audio input plug.
Sound Check One
Before the presentation, do a sound check. Make sure you are getting the right amount of sound. If the sound level is too high, you will get an annoying buzzing sound. If the sound level is too low, you won’t be able to hear the speaker in the back corners of the room.
Note: The transmitter and receiver each use a 9 volt radio battery.
