[. . . ] Position this side toward the sound source. BETA 181 General Rules for Use General Description The Shure Beta 181 is an ultra-compact, sideaddress, condenser microphone, designed for discreet placement in live and studio environments. [. . . ] · Avoid excessive handling to minimize pickup of mechanical noise and vibration. · Do not cover any part of the microphone grille, as this will adversely affect microphone performance. The following table lists the most common applications and placement techniques. Keep in mind that microphone technique is largely a matter of personal taste; there is no one "correct" microphone position. Meets Harmonized Standards EN55103-1:1996 and EN55103-2:1996, for residential (E1) and light industrial (E2) environments.
