Manufactured by:G.R.A.S. Sound & Vibration A/S based inHolte, DENMARK
Through a close cooperation with our customers, we know that data-safety is highly important because the costs related to unsuited and unreliable sensors may determine whether your project turns into a success or not. For our users, data safety translates directly into requests for easier microphone selection, simple system configuration and reduction of measurement errors. To meet these ...

The broad working range and reliability has made 40AO-FV the preferred prepolarized microphone for coupler and ear simulator setups and is the natural supplement or replacement of existing solutions. It is used for production line testing in coupler setups for test of hearing aids, earphones, headphones, and headsets. The KEMAR Manikin can also be configured with 40AO-FV for wide-band binaural ...

The GRAS 1/2" Preamplifier 26CA-HT is similar to the GRAS 26CA Standard Preamplifier, but optimzed for use in high-temperature applications up to 120 °C (248 °F). It uses a CCP (Constant Current Power) supply, e.g. GRAS 12AL 1-Channel CCP Power Module with A-weighting filter. It has a very low inherent noise level, a large dynamic range and a frequency response from below 2 Hz to above ...

The 41AC-3 is a small precision outdoor microphone according to IEC 61672-1 for monitoring of community noise and the noise of overhead ...
Manufactured by:G.R.A.S. Sound & Vibration A/S based inHolte, DENMARK
The 12AL will supply a transducer with a constant current of 4 mA. It has a wide operating frequency range from about 1 Hz (depending on load impedance) to well over 200 kHz. It also has an A-weighting filter which can be switched in or ...

The GRAS 12AX is a constant current power module for powering 4 CCP preamplifiers/microphone sets. It is optimized for integration into a production environment. The anodized enclosure is sturdy and offers good protection against dirt, dust, and moisture. Except for the power switch, it has no external user controls. In this way unintended change of the gain settings is ...

GRAS 40AE is a high-precision electret condenser microphone made according to IEC 61094-4 requirements. The electret technology for microphones was introduced in the beginning of the 1960’s and has been continuously improved over the years. At GRAS, we have developed and refined our own techniques. This guarantees that our prepolarized microphones are as stable and robust as our ...
