5. Operation
5.1: Power On:
After powering, the red and blue LED indicator on the panel
will flash alternately for a short time, after successfully
power on, it will turn into red light flashing.
If the LED indicator light is not on or always on, the
equipment will fail. It is recommended to power off and
restart the equipment firstly.
5.2: Pairing and Connect:
Press and hold the PAIR button for about 3s.
The LED red and blue indicators will start to flash alternately,
indicating that the DB-TR-44 is now visible to other
Bluetooth devices and accepts pairing. Then turn on other
Bluetooth devices to search for devices and pair. When only
the blue LED indicator flashes on the panel, it means that the
paired connection is successful.
(Notes: The DB-TR-44 maintains the last 10 paired devices,
any previously paired devices on this list will be allowed to
reconnect within the device range without re-requesting
pairing. The user only needs to select the corresponding
Bluetooth name on the smart device.)
5.3: Routing configuration:
Audio routing configuration can use Dante Controller
software or other compatible controllers to modify the input
configuration.
Channels 1 and 2 route stereo Bluetooth audio directly to the
Dante network.
Channels 3 and 4 route the analog signal RCA input or 3.5
mm TRS input to the Dante network.
The digital signal input of Dante equipment can be converted
to analog signal through Dante and output via 3.5mm TRS
interface.
Download and install the Dante Controller from Audinate
website (www.audinate.com).
