Setup AudioPoint system

This is also described in the Quick Install Guide: https://help.barix.com/audiopoint/documentation

To get AudioPoint up and running, you will need the following:

AudioPoint device
Wifi router/access-point
Smartphone (iOS or Android)

Setup your wifi first. AudioPoint will work with most Wifi Systems. If you use a Wifi Router, you can connect the AudioPoint directly to the router over Ethernet, otherwise, connect the device to the same LAN the Access-Point is connected to! Be aware, that the Wifi System is an important part of your AudioPoint setup, so if you have problems with the performance, check our performance-sheet with the most frequent problems and solutions: Bottlenecks and Performance optimization

After your Wifi is set up, connect your AudioPoint device and power it up! The device will work out of the box, with any configuration needed.

Download the AudioPoint App to your smartphone:

iOS: "AudioSignage", https://apps.apple.com/ch/app/audio-signage/id932316996
Android: "AudioPoint", https://play.google.com/store/apps/details?id=com.barix.audiopoint&hl=en

After you have downloaded the App, connect the phone to the wifi you set up earlier. After that, start the app and you will see the 2 default channels "Local_left" and "Local_right"

Device configuration

Accessing the Device

To access the Web Interface of the device, you have to connect it to the local network and you will need to find out the IP-Address of the device! Plug-in the Ethernet cable, the power cable and connect your headphones to the headphone jack on the front plate. after some time, the device will announce the IP-Address received from the DHCP Server (or from the router) over the connected headphones. If you don't have any headphones available or the IP-Address is never announced (it can be disabled in the settings) you will have to download the Barix Discovery tool to find the device on the network. Download the discovery tool from https://www.barix.com/downloads. Be aware, that you need to have the Java Runtime Environment installed since the discovery tools is a Java application and your PC needs to be on the same network than the AudioPoint device.

After you received the IP-Address of the Device, either over SonicIP© (over the headphones) or over the Barix Discovery Tool, you can access it by entering the IP-Address into any browser (chrome or firefox are prefered) like this: http://192.168.1.15. You will be prompted to put in a username and password:

You can find the login credentials on the back of the device on a white sticker. the password is unique per device and can be changed in the configuration while the username will always be admin!

Password information

Be aware, that Barix is not able to restore any password if the sticker is not readable or is lost!

If you reset the device, the password will be reset to the factory default one (the one on the sticker).

Configuration

The AudioPoint solution runs out of the box without any configuration needed. If you want to change default configuration and customize the solution, enter the device and go to the CONFIGURATION section on the main menu on top of the page. Below you see all possible settings with a short description.

Status page & Logs

The Status page (STATUS Tab on the Main Menu) shows all information about the device. In addition, you can see or download the system log on the LOGS Tab. In a support case, send this page together with the channel configuration page to the barix support!

QR-Code Scanning

An AudioPoint channel can be provided through the App directly or you can provide a QR-Code with a link to the Channel. The QR-Code can be scanned inside the App and will be played. This can be very handy if you want your customer to listen to a channel on at a specific time or place.

To use this feature you will need to know:

the IP-Address of the device
the Channel Name
the Subscription Port of the Channel

create the URL for the QR-code with the information above like this: audiopoint://<ip-address>:<port>/<channel-name>

For example: audiopoint://192.168.1.105:9444/Local_left

After you have the URL for your AudioPoint channel, create a QR-Code based on that URL. You should now be able to scan the code in the AudioPoint App to subscribe to the channel.
