Avisoft UltraSoundGate Player 116 User manual

Components of the UltraSoundGate Player 116Introduction
Thank you for purchasing Avisoft UltraSoundGate Player 116. This
bus-po ered USB device provides a 16 bit D/A converter, a po er
amplifier and a bias voltage generator for electrostatic speakers.
The accompanying recording soft are Avisoft-RECORDER USGH
can play standard . av files acquired by the Avisoft-UltraSoundGate
ultrasound recording interfaces or other third-party equipment.
1 Speaker Output Connector
The 4-pole Speakon connector provides the analog speaker output
and a 200V bias voltage for driving electrostatic speakers. The
connector scheme is as follo s:
2 Playback volume ad ustment knob
This control knob adjusts the analog output level of the po er
amplifier. In addition to that, the output level can be attenuated in the
RECORDER USGH soft are 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 allo s 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 s itch) ill activate the logic TRG
button. For a reliable electrical connection, a S itchcraft 0.01” Micro
Plug (part number 850X) is recommended.
4 TRG button
This button represents a logic game controller button that can be used
to start the playback of . av files in the RECORDER USGH soft are
(command Play/Settings/”ext trigger” = “joystick b2”).
Joystick b1 (auto hold) : Pressing the button for more than 2 seconds ill activate an
auto hold mechanism on the logic joystick button #1. If the button is pressed again, the
logic button #1 ill 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 (Inverse): 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, hich ill
activate the logic button permanently after pressing the physical button. Pressing the
button again ill reset the logic button.
5 DOUT
This 2-pole (mono TS) 2.5mm mini-jack connector carries the state
of the LSB (bit 0) of the 16-bit data ords of the 16 bit . av file that
is currently played. The digital output does not ork hen playing 8
bit . av files. This digital signal can be used to synchronously
control (trigger) other external devices hile playing a . av file. The
Avisoft SASLab Pro/Lite drop-do n menu
File/Specials/UltraSoundGate DIO can be used to edit the DO bits
of the . av files to be played.
The connector scheme is as follo s:
Tip : DO, Sleeve : GND
For a reliable electrical connection, a S itchcraft 0.01” Micro Plug
(part number 850X) is recommended.
6 OVERload indicator
The red OVERload LED indicates clipping. Clipping occurs hen
the po er supply voltage for the po er amplifier section is not high
enough to reproduce the input signal at the current playback volume
setting ithout distortion. If this happens, the playback volume (2)
should be reduced or the external po er supply voltage (connected
to 10) should be increased.
7 PLAY LED
This amber LED indicates the playback of a . av file (permanent
light). The LED flashes hen currently no file is being played.
8 POWER indicator
This green LED indicates the presence of the po er supply voltage
for the po er amplifier section of the unit.
9 POWER source selector
This s itch allo s to select the po er supply source for the po er
amplifier section of the device. If the s itch is at the USB position
(do n), the amplifier ill be po ered from the USB. Due to certain
po er constraints, the maximum playback po er ill be limited in
this case to about 1 W. At the EXT position (up), the amplifier is
po ered from an externally attached supply voltage (10).
10 External power supply socket (+12...36V)
This 2.1 mm coaxial po er supply socket allo s to connect an
external supply voltage in order to increase the playback po er
capabilities. The voltage should be bet een 12 and 36V DC. At
12V, the available po er is about 1W, at 36V it is about 10W.
11 LINE OUT
The LINE OUT cinch socket provides the analog output signal
directly from the D/A converter output (level: 4Vpp).

Installation procedure
First install the RECORDER USGH soft are either from the
supplied soft are installation media (navigate to the subfolder
RECORDER USH and run setup.exe) or from the Avisoft
Bioacoustics ebsite ( .avisoft.com/do nloads.htm or directly
.avisoft.com/RECORDER USGH.exe). This installation
program ill 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” 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 UltraSoundGate
Player 6 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 ill then look like this:

There are several ays to play a . av file:
a) Select the desired file from the command Play/File...
b) Locate the desired file on a Windo s folder and drag it into the
RECORDER USGH indo .
c) Prepare a list of files from the command Play/Playlist... and play
the selected files according to the settings made there.
Once a . av file has been selected (according to the above option a
or b), this file can be played several times either by executing the
command Play/Start (Shift+Space bar), by clicking at the Play button
or by pressing the physical trigger button on the device.
The latter option requires that the “joystick b2|b6” option has been
selected as the “ext start trigger” from the command Play/Settings...
Getting started
User's Guide
After installing the Avisoft-RECORDER USGH Soft are and
connecting the UltraSoundGate Player to the computer, the
RECORDER USGH soft are can be launched from the Windo s
Start menu All Programs / Avisoft Bioacoustics / RECORDER
USGH.
The playback functionality of the RECORDER soft are is located on
the Play menu.
First go to the command Play/Device... and select the Avisoft
UltraSoundGate Player 116 from the Device listbox at the top of the
dialog box and select the playback rate. The default playback rate
setting “use file header rate” ill use the file header sample rate of the
. av file, hich ill ensure that the file is being played at the correct
speed. Note that the USG Player only supports a limited number of
sample rates (500, 384, 375, 300, 250 kHz, ...). If the original . av file
to be played has a different sample rate, it is necessary to either
resample it to one of these sample rates in advance (Avisoft-SASLab
Pro command “Edit”/”Format”/”Sampling Frequency Conversion...”) or
to select the option real-ti e oversa pling, hich ill perform the
required sample rate conversion in real-time. The list box titled
nu ber of taps (accuracy) ill determine the accuracy of the
conversion. Higher values ill increase the accuracy but ill also
increase the CPU usage. Slo er PC's may be unable to process the
data in real-time ( hich can be recognized by a distorted playback
and the inability of the RECORDER soft are to respond to user inputs
during the playback). Under these circumstances, it is therefore
recommended to resample the sound files in advance in Avisoft-
SASLab Pro/Lite.
In the bus-po ered operation mode, the option “switch power off
when not in use” ill reduce the current dra n from the USB hile
no file is being played (the po er amplifier ill be s itched off
bet een playbacks). Ho ever, s itching on and off the amplifier at
the begin and end of each file can create an undesired noise. If this
noise is unacceptable, the option should be disabled.
The option enable 200V bias voltage should be activated hen
electrostatic speakers are being used.
The option reject LED blinking ill s itch off the amber-colored Play
LED during standby mode hen no file is being played (other ise the
LED is blinking to indicate the USB connection).
When simultaneously playing via the USG Player and recording via
an UltraSoundGate xx16 at the same time, it is necessary to launch a
separate instance of the RECORDER USGH soft are for the
playback task. Other ise, the recording and playback procedures
might disturb each other (gaps might occur in the data streams)
Another issue related to the simultaneous playing and recording ith
an UltraSoundGate 116 or 416 is the limited USB 1.1 full-speed bus
band idth hen both devices are connected to the same roots HUB
of the computer and the sample rates exceed 250 kHz (at 16 bit
resolution). This constraint can be resolved by connecting one of the
devices through an USB 2.0 HUB to the computer. This ill convert
the full-speed mode of the device to the high-speed mode and both
devices can be operated at the same time from a single USB 2.0
port.
For best results, the bit depth of the . av files to be played should be
16 bits and the sample rate as high as possible (500 kHz). A high
sample rate ill avoid aliasing effects by shifting potential aliasing
products to ards higher frequencies. Use the SASLab Pro command
“Edit”/”Format”/”Sampling Frequency Conversion...” to increase the
sample rate.
Additionally, it might be necessary to activate the USG Player game
controller from the Windo s Control Panel (Hard are and Sound >
Game Controllers) in order to get it ork ith the RECORDER USGH
soft are:
