With the wireless mic the equipment has numbers and you must keep the ones with the same number together. secondly the lapel wire must go down your back and also not be to high on your shirt. when using the hand mic always keep it about two centimetres from your chin because if it is to far away from you it won’t pick up the sound and if you have it touching you chin it will pick up the sound of it scratching against your chin.
there are two rectangular prisms with an R and a T on them meaning receiver and transmitter, the transmitter gives the sound to the receiver which gives it to the camera. make sure the receiver is on the camera and not the director so that the director can leave the camera without dragging it along. These two rectangles can mean that you can go for about 30 meters and still have a very good sound.
