Is there a recommended microphone for use with the 371 SPL Computer?
For most applications, an inexpensive low-impedance, omnidirectional microphone, such as a lavaliere microphone works adequately. Some installers have used boundary microphones with good success (they're unobtrusive). Other installers have mounted microphone cartridges (available from Mouser Electronics in the U.S.) inside…
Where is the best placement for the 371 SPL Computer sensing microphone?
Ultimately the sensing microphone should be placed so that it's picking up as much of the ambient noise as possible and as little of the speaker program as possible. The sensing microphone needs to "hear" the ambient sound within the…
When must you calibrate the 371 SPL Computer?
Calibrate at a quiet-to-average time in the controlled space. It helps if you have an estimate (sound pressure level) of the maximum desired level. Check the sound system to see that it is capable of delivering that level.
How does the 371 SPL Computer know the difference between the paging / music and ambient noise?
During the calibration procedure the 371 uses AmbiSense technology to calculates the percentage of the sense signal that is picked up from the paging and/or music that is going through the sound system. AmbiSense allows music or page pickup without…
