The default configuration is for single device use with Port B
disabled and Ch2 transmitting via Port A.
Figure 15 –Switch/Label Config Options
–BT1 –Device Settings
The BT1 is designed use in a number of configurable modes to
facilitate comprehensive use in professional AV applications. The
following sections describe the available modes and their
functionality.
–Bluetooth® Pairing/Connect Modes
4.3.1.1 –Manual Mode
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
status LED will begin flashing blue to indicate that the BT1 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 BT1 will disable its Bluetooth®
interface.
*Note: The default Bluetooth friendly name visible to other
devices is “BT1-xx:xx:xx”. This name can be customized by the
installer using the unIFY Control Panel software.
If a successful pairing is made during the pairing period, the
status LED will stop flashing and turn constantly on.
To disconnect a Bluetooth device from the BT1, 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.
4.3.1.2 –Reconnect Mode
In this mode, the BT1 maintains a pool of the last 10 paired
devices and any previously paired device on that list will be
permitted to reconnect when in range of the BT1 without
requiring the front panel button to be pressed. The user simply
selects the BT1 friendly name on their smart device.
Any new devices that are paired are added to the paired device
list. If the list already full, a random device from the list will be
removed and the new device added in its place.
4.3.1.3 –Exclusive Mode
This mode is intended for restricted/personal use and works
similarly in operation to reconnect mode. However, rather than
allow any known device from the pairing list to reconnect, only a
specific device can be used with that particular BT1.
To setup a device as the exclusive device, set the BT1 to
“Exclusive” mode, clear the pairing list, and then pair the desired
exclusive device to the unit. The BT1 makes a note of this device
and from that point on, only that exclusive device will be allowed
to reconnect to that particular BT1 when in range. As with the
reconnect mode, reconnection is done without requiring the front
panel button to be pressed by simply selecting that particular BT1
on their smart device.
Once the BT1 has been associated with a device, both the front
panel pair button and the remote “pair” command sent via the
network are disabled and will have no effect.

Attero Tech by QSC Axiom Product Family
User Manual
QSC, LLC 2020 614-00063
In order to attach a different device, either pairing list has to be
cleared or the device mode needs to be changed.
*Note: In all modes once paired/connected, the Bluetooth®
friendly name is able to be detected by 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.
–Bluetooth® Audio Bridging
4.3.2.1 –Media Bridging (only)
In this mode (A2DP profile), users may stream audio from media
applications on the paired device. The user is protected from
errant streaming of call audio over Bluetooth® link.
The media bridging mode is an excellent solution for applications
such as hospitality, retail and fitness center background music
where users want to maintain call privacy while sharing media
audio from their device’s media applications.
4.3.2.2 –Call Bridging (only)
In this mode (HFP profile), users may stream incoming/outgoing
calls from the paired device to/from the Axon-connected input
and output. In this mode, the user is protected from errant
streaming of media audio over Bluetooth® link.
The call bridging mode provides call connectivity for conferencing
system users’ Bluetooth equipped devices to a networked audio
based conferencing system. The addition of Bluetooth
connectivity provides simple bridging of far end meeting
participants for on the fly meeting productivity and backup
conferencing connectivity in case of VoIP and Web-based
conferencing service failures.
4.3.2.3 –Call & Media Bridging
In this mode, both profiles are available giving users the ability to
control access of content (call and media) to the system from the
paired device.
*Note: If your application requires call privacy, it is recommended
to not utilize the combined call and media bridging mode as call
audio will be shared automatically over the audio connection.
–Bluetooth® Pass-through AVRCP (AV
Remote Control Protocol)
Many installed AV systems in both residential and commercial
markets feature control products with customizable user
interfaces. With a connected Bluetooth audio device as a source,
it is desirable to have access to the device information and source
content (artist / album / song) for use on the control system UI.
Additionally, the end user of the system may control the source
from any control panel that has this. This is useful if the device is
left somewhere to charge and is out of reach to simply change
songs or stop the audio playback.
Control API access is be available for the following AVRCP pass
through commands:
a) Play
b) Pause
c) Stop
d) Next Track
e) Previous Track
f) Volume Up
g) Volume Down
h) Mute
The AVRCP controls are provided within unIFY Control Panel for
system commissioning and testing.
