UltraSoundGate Player BL Light

part #70113
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.

A Samsung N220 Netbook (with 65 Wh battery) can continuously operate the playback system at the maximum sound level for approximately 12 hours if all available power saving options have been activated (unused components such as network, WLAN, Bluetooth, livecam disabled and screen switched off). Other suited netbook models providing a long battery life of around 10 hours are the TOSHIBA NB550D, HP Mini 210-3050 or Asus Eee PC 1015PW.
