Lapel microphone (Lavalier) to connect to Body Pack Prodipe As an optional extra, we wanted to provide a small-diaphragm Lavalier condenser mic which does justice to the timbre of your voice. It also turns out to be ideal for conferences and oral presentations in general (tie clip mic in conjunction with the Prodipe bodypack transmitter). The message is loud and clear!
