Measurement microphone / dynamic

Array microphones are used in situations where concurrent measurements are required at several points. For example in the analyses of:

* Sound fields
* Sound power
* Transients

They are also of particular value when measurement opportunities are few and far between either because of costs or repeatability.
The Array Microphone Types 40PH and 40PL are low-cost microphones for general-purpose measurements in arrays and matrices. They have a wide useful frequency range reaching up to and a large dynamic range topping at around 134 dB. They have an integrated CCP* preamplifier and built-in TEDS** enabling them to be programmed as a complete unit.

Their manin difference lies in the sensivity: the Array Microphone Type 40PH has a sensitivity of 50 mV/Pa as opposed to the Type 40PL, which has a sensitivity of 10 mV/Pa.

* Constant Current.Power Supply
** Transducer Electronics Data Sheet - according to IEEE-1451.4
