Introduction
Thank you for purchasing the Avisoft UltraSoundGate 116Unb.
This generic USB audio device supports sampling rates of up to
384 kHz. Thanks to its class-compliant USB audio interface de-
sign, it can be used with third-party / custom software on various
operating systems including Windows, Linux, Android and OS X.
In addition to that it can also be used with the included Avisoft-
RECORDER USG/USGH recording software on Windows XP /
Vista / 7 / 8 / 8.1 / 10.
Installation procedure on Windows
A) Using the USB audio device driver of the operating system
When the Avisoft UltraSoundGate 116Unb is connected to the
computer at the first time it will be recognized as a Generic USB
Audio device (Microphone) and the required device driver will be
installed automatically. There is no further installation required
except of the selection of the desired sample rate. On Windows 10
it would look like this:
Note that there is only a limit num-
ber of sample rates supported by the
Windows USB audio device driver (48,
96, 192 and 384 kHz). The sample rate
of 384 kHz on conventional MME audio
driver based recording software (such as Avisoft-RECORDER
USG) will only function properly on Windows 10 Anniversary Up-
date or later.
B) Using the proprietary USGH.SYS device driver in combina-
tion with the Avisoft-RECORDER USGH software on Windows
In order to use the Avisoft-RECORDER USGH software (which
supports all sample rates up to 384 kHz on all Windows versions)
this software must first be installed either from the supplied soft-
ware installation media (navigate to the subfolder
RECORDER
USH
and run
setup.exe
) or from the Avisoft Bioacoustics website
(www.avisoft.com/downloads.htm or directly www.avisoft.com/
RECORDER%20USGH.exe). This installation program will install
both the RECORDER USGH application (rec_usgh.exe) and the
required device drivers (usgh_xx16h.inf, usgh.sys) for the Ultra-
SoundGate xx16H devices.
