PM1-x Microphone Placement.
Locate the PM1-x Microphone near the area of interest in the room to be monitored. If the entire room is to be monitored,locate the PM1-x in the middle of the room. Do not mount the microphone near air conditioning vents, light fixtures or electrical equipment. The PM1-x should be placed at least five feet away from the subject(s) to be monitored. The PM1-x is still useable in the range of 15-25 feet but is dependent on the level of background noise in the area. Experimentation in the environment will determine what distances work best. In outdoor applications, it is best to locate the microphone where it is not directly exposed to the elements to avoid accumulation of water, snow or ice. The PM1-WPW can withstand extreme weather but the collection tube may still become blocked as a result of direct exposure to precipitation.PM1-W and PM1-WPW have removable windscreens for cleaning purposes.
Run a 22 gauge, stranded, two conductor, shielded cable between the PM-1 microphone and the monitoring device or mixing console. Keep the cable run distance under 500 feet and away from AC power sources, light fixtures and electrical equipment. Connect the PM1- to a mixing console or other equipment as shown in the diagram below.
