Q:Coverage Range of U841A
A:Thank you for your inquiry. As in all things audio the answer to your question is "it depends". It depends on how loud your sound source is verses how loud the background noise is. It depends on how high you can set the gain on your audio system. It depends upon whether the microphone is used for sound reinforcement within the room where it is used or if it is used in video / audio conference or in a recording. Also, very importantly it greatly depends upon the acoustics of the room. All of these factors is one reason it can be a good idea to use an audio consultant or sound contractor when setting up a room and buying equipment.
