1. USB-micro connector for power supply 5V DC
2. Analogue audio output 3.5 mm jack
3. Digital audio output S/PDIF Toslink
4. Digital audio input S/PDIF Toslink
5. Analogue audio input 3.5 mm jack
3. Pairing/ coupling mode
In order for 2 Bluetooth devices to pair with each other, you must first pair them and activate pairing manually. The
connections are saved. The next time you switch on the device, pairing will then take place automatically.
3.1 Using the TX transmitter mode
Slide the switch 9 to TX. Then press the Bluetooth button twice to enter pairing mode. The TX LED will then flash
steadily and rapidly. Switch the Bluetooth function of your device (Bluetooth headphones, speakers or receiver, etc.) to
pairing mode. On most devices, a LED will then flash alternately red/blue or blue only. After about 5–30 seconds the
ABT00102 is connected to your device. The TX and A LEDs then light up constantly. If your audio device supports more
than the standard codec, one of the Codec LEDs (LL, HD, aptX) will also light up.
Then connect the ABT00102 to an audio source, e.g. TV, radio, game console, using a 3.5 mm audio cable or Toslink
cable. Use key 2 to select the desired input TX AUX analogue or OPTICAL digital.
Notes:
The ABT00102 always tries to establish the connection in the highest quality codec aptX HD first. Disable aptX
HD to prefer a connection in aptX low latency for audio transmission during gaming, video or TV.
If you are connecting to the digital output of your TV set (or TV receiver), set the audio format in the menu to PCM
stereo (not Bitstream, not Dolby Digital). Multichannel and bitstream audio signals can neither be decoded by the
ABT00102 nor transmitted via Bluetooth.
3.2 Multipoint connection with 2 headphones
First, pair up the first headphones as described in 3.1. Then double-press the Bluetooth key. The TX LED flashes
rapidly to indicate pairing mode. Now switch a second Bluetooth device (e.g. headphones) to pairing mode. After 5–30
seconds it will be paired. The TX, A and B LEDs now light up constantly. You can now listen to music with 2 headphones
at the same time, for example.
Note:
Some Bluetooth devices do not support multipoint. Only SBC codec is available for multipoint connections.
During the first seconds after pairing device B, you will have dropouts on audio device A.
