INTELLIGENT MEASURING EQUIPMENT www.roga-instruments.com AS-10 Professional Microphone for Acoustical Quality Assurance AS-10 The AS-10 is a compact professional microphone which is used to hear and to evaluate airborne noise. It has a length of 30cm and is equipped with a goose neck with a length of 30 cm. To the output receptacle at the back a headphone can be connected. The power supply is realized with a 9V block battery, which is located on the bakkside of the device. The battery can be changed by unscrewing the rear tube. After unscrewing the battery can be accessed and changed. After the device is switched on, the green operation LED is lit. The unit offers two amplification ranges with 30dB and 60dB.
