The scope of this document is to give a general introduction on the IP Former TPA400 helping the user to run a basic setup and have an audio stream playing out from the device.
- IP Former TPA400 device
- Speaker Connector
The Barix IP Former TPA400 is an audio over IP decoder which includes an amplifier to drive a loudspeaker. All configurations for this device are done locally on an integrated web interface. The operational status of the device is indicated by two multicolour LEDs (red/green).
STEP 1 Connecting to Audio Equipment
The IP Former needs connection to the Speaker Equipment through the screw connector provided on the front panel of the device. The speaker output supports speaker impedance of 4 and 8 ohms (2 ohms is also possible but the output power of the amplifier is optimized and configurable to match 4 and 8 ohms speakers).
STEP 2 Connecting to a PoE switch
Connect your IP Former to the Network using a standard Ethernet cable (CAT5e or better). The network will need to provide standard PoE power supply IEEE 802.3af (15W per port) or higher. The class negotiated is Class 0, which will allow the switch to deliver up to the maximum capability per port (power available at PD for 802.3af <= 12.95W).
- The IP Former is configured to be a DHCP Client by default.
- System Status LED green solid: Device has started up and is running.
- Application Status LED green solid: Application has started and is running.
Tips for a proper startup
- Verify that your speaker is connected to the IP Former
- Verify that your network cable is connected to a PoE Switch and a DHCP server is available within the network
- During startup, the IP Former will acquire an IP address and announces it on the speaker output
- By default the device will announce itself to a Syn-Apps server (and to an Informacast server if licensed), System Status LED and Application Status LED turn solid
The IP address of the IP Former is useful in order to do further configuration (e.g. configuring other sources etc) using its local web user interface via web browser.
Managing Sources and use of the IP Former
STEP 1 Login
- Use your web browser to log into the IP Former Web Interface by typing the IP Address into your browser.
- Use the user "admin" and the appropriate password provided on the sticker on the backside of the device (PW label)
STEP 2 Configure your Sources
For the configuration of your sources, the following source types are available:
- Syn-Apps → annouces the IP Former as an audio device in a Syn-Apps system
- Informacast (if licensed) → annouces the IP Former as an audio device in an Informacast system
- Barix Radio → plays Barix Radio as http stream without any further configuration
- RTP → configures the IP Former to receive an RTP stream
- HTTP(S) → configures the IP Former to receive an HTTP or HTTPS stream
- SIP → configures the IP Former to be a SIP client (peer to peer or Server mode)
- Local File → allows to play audio files which are locally stored on the IP Former
Please refer to the help description in the user interface in order to properly configure your sources.
Individual Volume can be set for every of the sources.
STEP 3 Prioritize your Sources
Multiple sources can be configured at the same time and are played according to their given priority.
- Priority 1: Highest priority
- Priority 5: Lowest priority
Management of priority means that a present stream will be played over another configured stream.
Example of a Priority System
- Priority 3: HTTP Radio Stream playing Background music.
- Priority 2: RTP Streams playing ads over the background music. Background music will stop as soon as the RTP stream is present
- Priority 1: SIP call playing emergency calls. Background music or advertisements will be stopped as soon as SIP call is present.
STEP 4 Manage Local Files
Use the menu item "Audio Files" in order to manage your local files for the source type "Local Files".
The device supports MP3, AAC, FLAC, AC3, DTS, OGG, WAV files.
The filenames should NOT contain special characters and must have maximum one space character in the name.
The limit of individual files to be uploaded is 16MB.
It is possible to upload .zip archives to upload multiple files at once.
Read the help side bar to know how to trigger the playback of the files on IP Former.
STEP 5 Control the IP Former
Once the sources are configured, the IP Former will start playing them accordingly. Master Volume of the IP Former can be controlled on the "Settings" page of the web interface.
STEP 6 Monitor the IP Former
The "Speaker Status" page on the web interface will show you the actual status of the sources of the IP Former. Every source status also includes a counter indicating how many times the actual source has been played.
Remote Configuration Tool
Any IP Former device present in the network has a tab called "Remote Config" exposed in the web UI. The configuration tool lists all the devices automatically discovered in the network and allow bulk or individual configuration of them to make a system-wise configuration and maintenance fast.
The Remote Configuration tool allows to:
- copy the configuration of one device to others
- save changes on device's configuration individually or in bulk
- group devices per zone and copy the configurations from one device to all in the same zone or to all zones
- sort and filter devices easily by their: names, zone, IP, MAC, source configuration.
- edit the device name
- change the device settings
- change the sources configuration and the playback priority
- reload all device's configurations or cancel the changes done
- open the webUI of another device
- perform a sound-test of a device
- Immediately view how many devices are in the network
- See which source the device is playing (green cells)
For more details on how to use the tool read the help side bar accessible clicking on the in the right upper side of the page.
These settings are among the most important in the Settings page of the IP Former. In this section it is possible to Enable/Disable key functionalities:
- Reboot: enable or disable the soft reboot from web user interface (button grayed out)
- Reset Factory Default: enable or disable the possibility to reset the device to factory defaults from web user interface (button grayed out)
- Update Function: enable or disable the possibility to update the device from web user interface (button grayed out)
In the IP Former Settings page there are parameters used to configure your device with the desired network settings. To set the network settings:
- Wire your IP Former to a network where a DHCP server is available and switch it on, hear the IP announced over the audio output (SonicIP® function) and connect to its web browser
- Locate the Network Settings in the "Settings" menu
- Once settings are configured as desired click on Submit at the bottom of the page, the device will restart and if the IP is changed you must input the new address in the top bar
