6 – Bluetooth® Operation 

The unBT2Ais designed for two primary usage modes to facilitate a number 

of professional AV applications. 
 
*

Note: 

Once  paired/connected,  the  Bluetooth®  friendly  name  is  visible  to 

other devices. However, while another device may be able to pair and save 
to its Bluetooth® device list when in this state, breaking the connection of the 

currently active device will not be possible. 
 

Standalone Operation: 

This usage model is intended for applications where casual users of a public 

venue (sports bar, spa, stadium luxury box, fitness center) have access to 
connect their devices to the audio system but headaches are minimized by 

eliminating automatic reconnect and pairing history features. 
 

In this mode, users connect their Bluetooth® audio enabled smart device by 
simply  pressing  the  front  panel  “PAIR”  button.  The  blue  Bluetooth®  status 

LED will begin flashing to indicate that the  unBT2A is now visible to other 
Bluetooth®  devices  and  accepting  pairings.  This  pairing  period  lasts  60 

seconds after which the status LED will stop flashing and turn off and the 
unBT2A will disable its Bluetooth® interface. 

 

*Note: 

The default friendly name visible to other devices is “

unBT2A

”. This 

name  can  be  customized  by  the  installer  using  the  unIFY  Control  Panel 

software (v2.1 or greater). 
 

If a successful pairing is made during the pairing period, the status LED will 
stop flashing and turn constantly on. 

 
To disconnect a device from the unBT2A, press and hold the PAIR button for 

5 seconds and then release it. The status LED will turn off, and the connection 
will be reset. Another device may now be connected by repeating the pairing 

process.

 Party Integration: 

In this usage model, the unBT2A is integrated into a large AV system that 

includes a 3

rd

 party control system. Using the RS-232 control port and the 3

rd

 

party programming API, integrators can customize the usage of the unBT2A. 
The control system the ability to configure the following functions: 

o

 

Limit errant connections by disabling the front panel control 

o

 

Implement user privileges by only initiating the pairing/connect process remotely through the control system 

user interface 

o

 

Report current unBT2A Bluetooth® interface status to the control system
