Avisoft UltraSoundGate Player 216H User manual

Components of the
UltraSoundGate Player 216H
Introduction
Thank you for purchasing Avisoft UltraSoundGate Player 216H.
This us-powered USB device provides two 16 it D/A converters,
power amplifiers and a ias voltage generator for driving
electrostatic speakers.
The accompanying recording software Avisoft-RECORDER
USGH can play standard .wav files acquired y 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 ias voltage for driving electrostatic speakers. The
connector scheme is as follows:
The left socket represents channel #1 (left stereo channel) and the
right socket elongs to channel #2 (right stereo channel).
2 Playback olume adjustment knob
This control kno adjusts the analog output level of the power
amplifier. In addition to that, the output level can e attenuated in the
RECORDER USGH software from the command Play/Play ack
volume...
3 TRG input
This 2-pole (mono) 2.5 mm mini-jack connector is electrically
connected to the TRG utton (4) and allows connecting an external
trigger. This input is TTL compati le (there is additionally an internal
pull-up resistor of 10 kOhm to Vcc). Pulling this input to ground (for
instance y closing a simple switch) will activate the logic TRG
button.
4 TRG button
This utton represents a logic game controller utton that can e used
to start the play ack of .wav files in the RECORDER USGH software
(command Play/Settings/”ext trigger” = “joystick 2”).
Joystick b1 (auto hold) : Pressing the utton for more than 2 seconds will activate an
auto hold mechanism on the logic joystick utton #1. If the utton is pressed again, the
logic utton #1 will e reset.
Joystick b2 : The logic joystick utton #2 represents the original state of the physical
utton (1:1 relation). This option should e used for normal applications.
Joystick b3 (In ersed): The logic joystick utton #3 represents the inverse state of
the physical utton.
Joystick b4 (Toggled): The logic joystick utton #4 provides a toggle mode, which will
activate the logic utton permanently after pressing the physical utton. Pressing the
utton again will reset the logic utton.
5 DOUT
This 3-pole (stereo TRS) 3.5 mm mini-jack connector carries the state of the
LSB ( it 0) of the 16- it data words of the 16 it .wav file that is currently
played. This digital signal can e used for instance to synchronously control
(trigger) other external devices while playing a .wav file. The Avisoft SASLa
Pro/Lite drop-down menu File/Specials/UltraSoundGate DIO can e used to
edit the DO its of the .wav files to e 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 play ack
volume setting without distortion. If this happens, the play ack
volume (2) should e reduced or the external power supply voltage
(connected to 10) should e increased.
7 PLAY LED
This am er LED indicates the play ack of a .wav file (permanent
light). The LED flashes when currently no file is eing 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 e powered from the USB. Due to certain
power constraints, the maximum play ack power will e limited in
this case to a out 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 play ack power
capa ilities. The voltage should e etween 12 and 36 V DC.
At 12 V, the availa le power is a out 2 x 1 W, at 36 V it is a out
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 su folder
RECORDER USH and run setup.exe) or from the Avisoft
Bioacoustics we site (www.avisoft.com/downloads.htm or directly
www.avisoft.com/RECORDER USGH.exe). This installation
program will install oth 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
e connected to the computer. The device should then e detected
as “Avisoft-UltraSoundGate Player 216H” and the pre-installed
driver should e 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 Pla er 216H and select the Update Driver
Software... option. Then click at Browse m 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:
channel #1 channel #2

There are several ways to play a .wav file:
a) Select the desired file from the command Play / File...
) Locate the desired file on a Windows folder and drag it into the
RECORDER USGH window.
c) Prepare a list of files from the command Play / Playlist... and
play the selected files according to the settings made there.
Once a .wav file has een selected (according to the a ove option
a or ), this file can e played several times either y executing the
command Play/Start (Shift+Space ar), y clicking at the Play
utton or y pressing the physical trigger utton on the
device.
The latter option requires that the “joystick 2| 6” option has een
selected as the “ext start trigger” from the command
Play/Settings...
Getting started
User's Guide
After installing the Avisoft-RECORDER USGH Software and
connecting the UltraSoundGate Player to the computer, the
RECORDER USGH software can e launched from the Windows
Start menu All Programs / A isoft Bioacoustics / RECORDER
USGH.
The play ack functionality of the RECORDER software is located
on the Play menu.
First go to the command Play / Device... and select the Avisoft
UltraSoundGate Player 216H from the Device list ox at the top of
the dialog ox.
Normally, the playback rate option “use the file header rate”
should e selected. In this case, the play ack sample rate will e
taken from the file header of the .wav file, which will ensure that the
file is eing played at the correct speed. Note that the USG Player
216H hardware only supports a sample rate of 1000 kHz. If the
original .wav file to e played has a different sample rate, it is
necessary to resample it to 1 MHz. This can e done for instance
in Avisoft-SASLa Pro from the command
“Edit”/”Format”/”Sampling Frequency Conversion...”
Alternatively, the sample rate can e converted y the RECORDER
USGH software in real-time. This mode of operation can e
activated y checking the option real time opversampling. The
list ox titled number of taps (accuracy) will determine the
accuracy of the conversion. Higher values will increase the
accuracy ut will also increase the CPU usage. Slower PC's may
e una le to process the data in real-time (which can e
recognized y a distorted play ack and the ina ility of the
RECORDER software to respond to user inputs during the
play ack). Under these circumstances, it is therefore
recommended to resample the sound files in advance y in Avisoft-
SASLa Pro.
In the us-powered operation mode, the option “switch power off
when not in use” will reduce the current drawn from the USB while
no file is eing played (the power amplifier will e switched off
etween play acks). However, switching on and off the amplifier at
the egin and end of each file can create an undesired noise. If this
noise is unaccepta le, the option should e disa led.
The option enable 200V bias voltage should e activated when
electrostatic speakers are eing used.
The option reject LED blinking will switch off the am er-colored
Play LED during stand y mode when no file is eing played
(otherwise the LED is linking 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 software for
the play ack task. Otherwise, the recording and play ack
procedures might distur each other (gaps might occur in the data
streams).
Additionally, it might e necessary to activate the USG Player
game controller from the Windows Control Panel (Hardware and
Sound > Game Controllers) in order to get it work with the
RECORDER USGH software:
USG Player 216H
Playing .wa files
In order to play two independent signals through the two channels of
the unit, a 2-channel (stereo) .wav file must e prepared. This could
e done for instance in Avisoft-SASLa Lite / Pro with the command
File/Specials/Add channel(s) from file... Use the command
File/Specials/Swap channels to interchange the two channels if
necessary. Single-channel .wav files will e reproduced through
oth channels.
