There are a few options to consider when hiring a microphone. Do you want a corded microphone, or a wireless microphone so that you can move around freely. The corded microphone has about 2-3 metres of cord. A wireless mic can work about 10-20 metres away from the receiver, depending on the environment that it is operating in.
To use a microphone, you need to connect it to a mixer, and then to a speaker to generate sound. You cant just hire a microphone on its own, unless you have sound equipment or a mixer of your own.
We do have an all in one portable speaker system with a microphone, that is battery powered. This is great for small outdoor events or outdoor presentations. No power is needed and it is ready to go, check out the Mipro portable speaker in the Audio Hire section.
