The boya by-mm1 pro is the professional shotgun directional microphone from boya. it is equipped with two microphones with which sound can be recorded from both the front and the back. this makes it possible to record both the interviewer and the interviewee without moving the microphone. partly because the boya by-mm1 pro comes with a rycote®lyre® shock mount, unwanted vibrations and noise are reduced to a minimum. Because the housing consists mainly of aluminium, the by-mm1 pro is a durable directional microphone. with a weight of 67.5 grams, the set is very lightweight and, with a size of ø22 * 84mm, very compact. the by-mm1 pro uses phantom power so you don't have to worry about the battery status. power is supplied by the device it is connected to.
