When connected to the impact sound sensors, it perceives and records analog audio signals. Independent frequency selection and headphones

This stereo stethoscope amplifier is used in connection with the provided impact sound sensors. The device is capable of perceiving and recording analog audio signals (human voice, footsteps, other sounds etc.). The oscillations transmitted by impact sound sensors undergo low-noise amplification (ultra low-noise amplifier), whereby even very weak signals get audible. An independent selection of threshold frequencies, amplification values and microphones ensures optimum adaptation to operating conditions.
