Software

The software required to configure a DBD-1200 depends on the device being used to connect to the modules within 
the amplifier:

 

■

Laptop – BLL software. Requires Windows OS.

 

■

Android – BLA software. Android version 4.1 or higher and USB host.

Note: We refer to BLL software and a laptop in this user guide but also apply when using an Android device with BLA. 

Installing the BLA software on a phone or tablet

1.  Ensure the device will allow unknown sources:

a.  Go to Applications > Settings > Applications
b.  Select - Unknown sources

2.  Copy the BLA vx.x.apk file to the device:

a.  Go to Applications > Settings > Wireless and Network > USB Settings
b.  Select Mass storage
c.  Connect the phone/tablet to your PC
d.  The drives of the phone will appear in file explorer
e.  Copy the .apk file to a suitable place on the phone/tablet

3.  Go to applications > my files
4.  Browse to the .apk file
5.  Click the BLA .apk file
6.  Select ‘OK’ to install
7.  Once installed you can select ‘open’ or ‘done’
8.  The Technetix BLA shortcut can now be found with all the other applications on your device.
