Environmental Shroud Models EPS2106 & EPS2108 for 1/2” Microphones and Preamplifiers Highlights I Protects preamplifier circuitry from humidity Shields microphone and preamplifier cable connection from rain, sleet, and snow Deters perching of birds near microphone Easily removable windscreen for quick calibration Desiccant cartridge condition easily monitored through transparent tube Simple procedure for replacing desiccant cartridges Mounting adapters and tripods available Integrates with Larson Davis instrument enclosures for portable/permanent noise monitoring applications Complies with Type 1specifications of IEC60651, IEC61672 and ANSI S1.4 1985 Outdoor noise monitoring under a wide range of environmental conditions – Community Noise – Aircraft Certification & Noise – Traffic Noise – Construction Noise – Perimeter Noise Model EPS210X Environmental Shroud is a complete weather protection system for Larson Davis ½ inch microphones and preamplifiers. The environmental shroud is a perfect choice for longer-term measurements in inclement weather. Its special acoustic windscreen material and configuration protect the microphone from rain, sleet, and snow. The shroud seals the preamplifier in a desiccated chamber, thus preserving performance in high humidity environments. The desiccant volume is many times greater than that of inline desiccant cartridges, for lasting protection without interference between the microphone and preamplifier. The shroud is also equipped with "bird-spikes" to deter birds and other animals. Model EPS210X is an inexpensive option to purchasing a full outdoor microphone preamplifier system with built-in rain hat, and electro-static actuator such as the Model 426A12. The excellent temperature stability of Larson Davis preamplifiers such as the Model PRM902, PRM831, and 426E01, allows operation in a wide temperature range without an internal heater. Additionally, Larson Davis microphones have outstanding resistance to acids and other corrosive agents making them a good choice for use with the environmental shroud. The Model EPS2106 fits on a 3/4 inch pipe which protects the cable from weather and animals. The Model EPS2108 can be mounted on a standard instrument or camera tripod having a 1/4 - 20 mounting stud. Larson Davis
