 I'm Andy from Riedel and in this video we're going to be talking about the meaning of the term BP. When we say BP we're actually referring to a belt pack such as our Belero unit which you can see here. A belt pack is something that is, as the name suggests, typically worn on the belt and allows the user to move around the production area freely staying in contact with colleagues. Especially if the belt pack is wireless such as the Belero, it really gives you a lot of freedom. It means that you can move wherever you like. With your headset you're always in contact. You can really think of it like a portable panel. It has an audio input, it has an audio output and as you can see it has some buttons.
