Larson Davis - Model PRM2103 -Outdoor Preamplifier

FromLarson Davis, a division of PCB Piezotronics

New Lower Cost Alternative Outdoor Preamplifier with all the necessary functionalities of Model 426A12 The Larson Davis PRM2103 has been designed to be used with an environmental shroud for portable or permanent outdoor use in a wide range of weather conditions. The PRM2103 combines the cost savings of a standard preamplifier with features for unattended monitoring and an inexpensive shroud to create a product that is ideal for remote sound level measurement. New in the PRM2103 is an automatic calibration check that checks five different frequencies all at the same time which enables better detection of any failure. When used with the Model 831 sound level meter, the acoustic response can be selected as free-field, random or 90 degree using a simple setting on the sound level meter. Because of this flexibility, only one preamplifier is necessary and there is no need to use different microphones for different fields.
