G.R.A.S. AL0010 Microphone Calibration Stand



The G.R.A.S. AL0010 Calibration Stand provides a convenient platform for testing condenser microphones. It has a fixture for holding a 1/2” preamplifier (e.g. G.R.A.S. 26AG) securely in place as well as recesses and a column for safely parking electro-static actuators (i.e. RA0014 and RA0015) and microphone protection grids when not in use. It can be set up for both 1/2” and 1” microphones.The AL0010 is a useful addition to a set-up (which includes a  G.R.A.S. 14AA Electrostatic Actuator Amplifier) for routinely calibrating condenser microphones.
