Measuring microphone "inno"
A measuring microphone with an integrated amplifier for the qualitative and quantitative study of nearby acoustic events. Its output can be read on an AC voltmeter, an oscilloscope or a frequency counter, with switchable amplification factors of 1, 3, 10, 30 and 100. The frequency range is 50–12,000 Hz (over 20 kHz for qualitative work) and it handles sound pressures up to 110 dB, with two 4 mm safety jacks and short-circuit protection. It is powered by four 1.5 V cells (included), rechargeable cells or an external 6 V/500 mA supply.
