Powering the CM15P and CM20PThe CM15P and CM20P are condenser microphones and therefore need to be operated by connecting a phantompower supply. Phantom power is standard on most quality mixers. If necessary, an external phantom supply, likethe Samson S phantom, can also be used. The CM15P and CM20P receive the phantom power directly from a micconnector or cable when connected to a mixer that includes a phantom supply. The power is sent OUT of the micro-phone INPUT, riding silently along with the audio signal. Most mixers have a switch to engage the phantom power,so be sure to check that the phantom power is on.Microphone Placement and PositioningThe CM15P and CM20P have been designed to be placed on a podium or table top and connected to a standard XLRconnector. In order to reduce the occurances of "p-popping", always use the supplied windscreen. Since the CM15P andCM20P have a uni-direction pick-up pattern, be sure to position the microphone towards the sound you want to pickup, and away from sound you do not want to pick up. In order to maximize the sound quality, you must pay carefulattention to the placement of your CM15P and CM20P and how it is positioned for the instrument or vocalist that youare miking.
