Components of the
UltraSoundGate Player 216H
Introduction
Thank you for purchasing Avisoft UltraSoundGate Player 216H.
This bus-powered USB device provides two 16 bit D/A converters,
power amplifiers and a bias voltage generator for driving
electrostatic speakers.
The accompanying recording software Avisoft-RECORDER
USGH can play standard .wav files acquired by the Avisoft-
UltraSoundGate ultrasound recording interfaces or other third-
party equipment.
1 Speaker Output Connectors
The 4-pole Speakon connectors provide the analog speaker outputs
and a 200V bias voltage for driving electrostatic speakers. The
connector scheme is as follows:
The left socket represents channel #1 (left stereo channel) and the
right socket belongs to channel #2 (right stereo channel).
2 Playback volume adjustment knob
This control knob adjusts the analog output level of the power
amplifier
.
In addition to that, the output level can be attenuated in the
RECORDER USGH software from the command Play/Playback
volume...
3 TRG input
This 2-pole (mono) 2.5 mm mini-jack connector is electrically
connected to the TRG button (4) and allows connecting an external
trigger. This input is TTL compatible (there is additionally an internal
pull-up resistor of 10 kOhm to Vcc). Pulling this input to ground (for
instance by closing a simple switch) will activate the logic
TRG
button
.
4 TRG button
This button represents a logic game controller button that can be used
to start the playback of .wav files in the RECORDER USGH software
(command Play/Settings/”ext trigger” = “joystick b2”).
Joystick b1 (auto hold)
: Pressing the button for more than 2 seconds will activate an
auto hold mechanism on the logic joystick button #1. If the button is pressed again, the
logic button #1 will be reset.
Joystick b2
: The logic joystick button #2 represents the original state of the physical
button (1:1 relation). This option should be used for normal applications.
Joystick b3
(Inversed)
: The logic joystick button #3 represents the inverse state of
the physical button.
Joystick b4
(Toggled)
: The logic joystick button #4 provides a toggle mode, which will
activate the logic button permanently after pressing the physical button. Pressing the
button again will reset the logic button.
5 DOUT
This 3-pole (stereo TRS) 3.5 mm mini-jack connector carries the state of the
LSB (bit 0) of the 16-bit data words of the 16 bit .wav file that is currently
played. This digital signal can be used for instance to synchronously control
(trigger) other external devices while playing a .wav file. The Avisoft SASLab
Pro/Lite drop-down menu File/Specials/UltraSoundGate DIO can be used to
edit the DO bits of the .wav files to be played.
The connector scheme is as follows:
Tip : DO channel #1
Ring : DO channel #2
Sleeve : GND
6 OVERload indicator
The red OVERload LED indicates clipping. Clipping occurs when
the power supply voltage for the power amplifier section is not high
enough to reproduce the input signal at the current playback
volume setting without distortion. If this happens, the playback
volume (2) should be reduced or the external power supply voltage
(connected to 10) should be increased.
7 PLAY LED
This amber LED indicates the playback of a .wav file (permanent
light). The LED flashes when currently no file is being played.
8 POWER indicator
This green LED indicates the presence of the power supply voltage
for the power amplifier section of the unit.
9 POWER source selector
This switch allows to select the power supply source for the power
amplifier section of the device. If the switch is at the
USB
position
(down), the amplifier will be powered from the USB. Due to certain
power constraints, the maximum playback power will be limited in
this case to about 2 x 0.5 W. At the
EXT
position (up), the amplifier
is powered from an externally attached supply voltage (10).
10 External power supply socket (+12...36V)
This 2.1 mm coaxial power supply socket allows to connect an
external supply voltage in order to increase the playback power
capabilities. The voltage should be between 12 and 36 V DC.
At 12 V, the available power is about 2 x 1 W, at 36 V it is about
2 x 10 W.
11 LINE OUT
The LINE OUT cinch sockets provide the analog output signals
directly from the D/A converter outputs (signal level: 4Vpp).

Installation procedure
First install the RECORDER USGH software either from the
supplied software 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 USGH.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 UltraSoundGate xx16H devices. When the
installation procedure has completed, the UltraSoundGate unit can
be connected to the computer. The device should then be detected
as “Avisoft-UltraSoundGate Player 216H” and the pre-installed
driver should be finally activated.
Under some circumstances it might happen that the silent
installation of the device driver fails. If that happens, navigate to the
Windows Control Panel
>
Hardware and Sound
>
Device Manager
and right-click at the entry
Other devices
>
Avisoft Avisoft-
UltraSoundGate Player 216H
and select the
Update Driver
Software..
. option. Then click at
Browse my computer for device
driver software,
click at
Browse
and navigate to the folder
C:\Program Files (x86)\Avisoft Bioacoustics\RECORDER
USGH\Drivers
and finally click at
Next
. The completed device driver
installation will then look like this:
