Larson Davis Announces the New PRM2103 Outdoor Preamplifier with Automatic Calibration Check
With the launch of the new PRM2103 Outdoor Preamplifier, Larson Davis now offers a full spectrum of outdoor microphone solutions.
Farmington Hills, MI - The Larson Davis PRM2103 Outdoor Preamplifier is designed for use with the Model 831 Sound Level Meter, the 377B02 microphone, and 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.
The new PRM2103 features an automatic calibration 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. Due to this flexibility, only one preamplifier is necessary and there is no need to use different microphones for different fields.
Because field visits to a remote monitor can be expensive and time consuming, the PRM2103 has been designed to require no routine maintenance. It includes a built-in humidity and temperature sensor and can automatically turn on an internal heater when there is a risk of condensation. All this has been accomplished while keeping power usage low (< 2 mA with heater off) so the PRM2103 is an excellent solution for battery powered applications.
