Microphones – Preamplifier High Pass and A-weighted Filtering

The GRAS Sound and Vibration Model 26 CF preamplifier provides switchable high pass and A-weighted filtering. The integrated 20 Hz high pass filter helps eliminate inaudible low frequency signals from entering the data acquisition system and using up headroom. An integrated A-weighted filter removes energy as defined in by the A-weighting curve, allowing you to make A-weighted […]
