GRAS 41AC Outdoor Microphone Kit

Introduction

The 41ACis a small outdoor microphone kit according to IEC 61672-1 for noise monitoring.

Design

The 41AC has been designed to meet the need for a precise and reliable outdoor microphone that can be part of a permanent installation. The 41AC is waterproof and fulfills the requirements of IP-55.

Microphone and preamplifier are mounted inside a high-grade stainless steel housing. The top cone – also made of stainless steel – has been perfected for best acoustical response. In addition to its acoustical function, the top cone acts as a bird spike.

The windscreen eliminates the effects of airflow and also serves as part of the 41AC’s water protection. It is glued to a detachable tube that ensures correct positioning. A locking system eliminates the risk of accidental dislocation. It is designed to withstand a wide range of weather conditions and temperatures for a very long period, i.e. easily a year or longer.

It comes with an adapter for pipe mounting. An adapter for tripod mounting is also part of the delivery.
