UltraSoundGate Player BL Light
UltraSoundGate Player BL Light is a cost-effective ultrasound playback unit for luring bats. The system consists of an USB computer interface, D/A converter, power amplifier, speaker, tripod mount and playback software. It is entirely powered from the USB interface of the computer (bus-powered), which means that no additional batteries are required. An attachable eye allows to hang the unit on a mist net pole or a tree.
The comfortable playlist feature of the accompanying RECORDER USGH software allows to play both original, noise-reduced or fully synthesized bat calls in random order and at random intervals. A growing collection of European bat sounds that are suited for this purpose is available at www.batcalls.com.

Functional principle of the UltraSoundGate Player BL Light
Frequency response of the built-in speaker
Note that playing back (ultra)sounds in the field for attracting wild animals usually requires an official license or permit issued by the local nature conservation authorities!
Due to the potentailly very high sound levels at close distances, keep away from the speaker or wear a hearing protector during playback!
