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.
