4- Select the destination folder
5- Select the Programm destination folder

6- The software will install all the driver, dll and all the things necessary for the installation. A
reboot is necessary after the installation (and suggested)

ENG

Warning! The installation procedure must be done with only ONE “Streamer” at the time
2 Installation of STREAMER RX
1.
Plug the network cable into the network port of the “Streamer RX” device and the other end into
your hub or switch.
2.
Plug the jack of your earphone into the headphone output.
3.
Plug the power supply into the power jack of the device and the other end into the power outlet of
the wall.
4.
After few seconds, will play a typical sound if a network is founded.
5.
To verify the IP address assignement and manage the other parameters of “Streamer” you can use
Streamer Control software. Install and running Streamer Control. Verify that no firewall is active into
your PC.

. If
DHCP
ACTIVE is displayed you can procede from step 7. If the DHCP server status detector shows DHCP
NOT PRESENT procede from step 9.

The active parameters of the “Streamer” that you selected, will be showed into EEPROM and RAM
column. Now you can test the decoder audio function using UDP Streaming Test utility. By clicking
on the START button of UDP Streaming Test there will be the streaming of an audio MP3 file to the
IP address of “Streamer” select
ed. The suond will be played through the headphone and the RCA
pin (“Streamer” only, not “In-Streamer”). The audio parameters, like volume, bass, treble and
loudness can be changed via the Audio setting. The streaming will stop at the end automatically but
yuo can stop it in any moment by pressing the STOP button.

If
DHCP NOT FOUND
message will appear on the top of
NS1 Tools
form this means that any DHCP
server is present in your network and that any IP address has been assigned to “Streamer”.
Therefore, IP values of “Streamer” have to be assigned manually. We suggest to chose carefully
your IP address or to contact you network administrator to avoid any conflict with other network
devices.
10.
To set manually the parameters of “Streamer” you have to select the device in the list box. After the
Warning messages you will be ready to assign the network values to “Streamer”.

Selecting the “Streamer” device will show you the new network parameters. As you will see the
EEPROM parameters will be transferred to RAM column. This means that your “Streamer” can be
reached on the network through the new IP value stored.
14.
Now you can test the decoder audio function using
UDP Streaming Test
utili
ty. By clicking on the
START button of UDP Streaming Test there will be the streaming of an audio MP3 file to the IP
address of “Streamer” selected. The suond will be played through the headphone and the RCA pin

2 How To Decode Audio Streaming With “Streamer RX”
For installation and configuration refer to Chapter 1
1.
To manage the decoding parameters of “Streamer” you can use
Streamer Control
.
Verify that no
firewall is active into your PC.
2.
Pushing
Get List !
button,
you will see as follows

3.
By clicking on device inside the list box all the parameters of the item selected will appear. Now you
can set the decoding parameters.
4.
Streamer RX can decode only UDP streamings. To decode an UDP audio streaming you have to
press the UDP button into “Streamer RX” decoding setting section. Then “ANNOUNCEMENT (UDP
mode)” message will be displayed in the right window. If a streaming is addressed to the multicast
or unicast IP address of “Streamer RX” this will decode it immediately. Depending on the network
traffic, it could be necessary to set the “Streamer RX” buffer delay (values admitted from 0 to 500
ms).
If you want to decode a TCP streaming you have to mount the memory option on the “Streamer
RX” board by upgrading it into Streamer RX version.
5.
You can check the “Streamer
RX
” proper decoding by the
UDP Streaming Test.
By pressing the
START button a short mp3 file will be sent to the “Streamer RX” selected. You can also check the
right audio decoding of all the “Streamer RX” devices on the network simply by pressing Get List !
followed by START button: the same short mp3 file will be sent to the default “Streamer” IP
multicast address.
6.
During playback you can set volume, bass and treble level and choose either to activate or not the
loudness of the “Streamer RX selected”. All the values will be stored in the “Streamer RX”
EEPROM. You can also reset to default values the audio parameters by pressing Reset button.

3 How To Encode Audio Streaming With “Streamer RTX”
For installation and configuration refer to Chapter 1
1.
To manage the encoding parameters of “Streamer” you can use
NS1 Tools
software.
Verify that no
firewall is active into your PC.
2.
Pushing

button
, you will see as follows

3.
By clicking on device inside the list box you will have all the parameters of the item selected. Now
you can set the encoding parameters.
4.
The parameters neededs to start to encoding are:
IP Address
:
unicast or multicast IP address of “Streamer” player/s targets
Port:
destination port of “Streamer” player/s targets. All the “Streamer” models are ready to
receive the streaming throught 6244 port.
Frequency:
audio sampling frequency.
Channels:
mono or stereo mode. If you choose to use the microphone input remember to use
the 1 channel option.
Bit Reservoir:
to improve the streaming audio quality it have to set on 0
Quality:
The encoder uses Variable Bitrate Encoding (VBR) to realize optimal compression of
the audio data. The setting of a fixed bitrate is replaced with setting a quality level
that preserves audio quality in critical sections and enhances compression otherwise.
The minimum bitrate (in case of digital zero samples) is 32 kbit/s for MPEG 1 and 8
kbit/s for MPEG 2. The maximum bitrate is 192 kbit/s for MPEG 1 and 160 kbit/s for
MPEG 2. The following table gives an overview on the average encoding bitrate that
can be expected for common audio signals at different quality settings and sample
rates.
