3 A MESSAGE FROM FRONTIER LABS
Thank you for using our Bioacoustic Audio Recorder – Long Term (BAR-LT).
We designed the BAR-LT with the goal of creating the best possible bioacoustic recorder for
scientific field research. To that end we created a recorder that is simple to use and easy to deploy
with best in class sound quality so you can hear quiet and distant calls, and we made it strong and
reliable with the smallest size and weight possible so it's easier to carry in a backpack. We included
features like GPS location and time-synchronisation to save you manual work in record keeping
and we designed smart microphones with the lowest noise, a built in pre-amp and cable driver that
tells the BAR when they're connected and what type of mic it is. And we designed it to use high-
density rechargeable lithium batteries instead of bulky and wasteful Alkalines that just end up in
landfill.
We designed the BAR to make your field work easier and more reliable. We hope you enjoy using it
and if you have any feedback or ideas for improvements, we would love to hear from you.
