The BTA-2 is a wall-mounted local input module for A-BUS installations that allows the easy integration of any Bluetooth® audio source such as those from a phone or tablet. Whenever a Bluetooth signal is received, the BTA-2 will automatically switch the active audio source to the Bluetooth device, making it simple and easy to use by any homeowner. The advanced Bluetooth radio module with aptX® audio encoding offers a higher quality audio signal whenever an aptX-enabled Bluetooth device is utilized as the music source. The BTA-2 may be used with all A-BUS installations. For installations where more than one BTA-2 is desired, a Windows® software application is available free of charge to allow for custom naming of each BTA-2 as well as to allow for the use of a customized password for security purposes.
