The AR125 is a professional quality ultrasonic receiver that is designed for ultrasonic recording and acoustic analysis.  It employs a directional, wide bandwidth ultrasonic element along with ultrasonic to digital conversion technology to produce a   high quality, 16-bit, digitally sampled acoustic stream that is injected directly into a laptop, lab computer, or field recorder.

The AR125 has a 1KHz to 125KHz frequency range and an outstanding 90dB dynamic range.  The combination of features and performance make the AR125 a very cost effective high performance receiver.

The AR125 is specifically designed for applications such as bat recording and vocalization analysis where directivity and a wide ultrasonic frequency range are desired.  It employs low noise circuitry along to achieve high sensitivity along with a large dynamic range.  It is sensitive enough to detect the faintest sound a human can hear (0 dB SPL) and it is capable of detecting bats at distances up to several hundred feet.
