  • Page 6: Power Supply

    Power Supply 1, Power supply – J8 Suggested power supply should be 19V 2.1A. You can also use any power supply whose output voltage is within DC12-26V and current is higher than 1A. Please note power supply out of the recommended range may cause damage to the amplifier board.
  • Page 7 Power Supply 2, Battery board – J6 Besides power supply, JAB3+ supports battery power which greatly improves the portability. There is no charging circuit equipped on JAB3+. If you want to power JAB3+ with battery power, it is suggested to use WONDOM BCPB series, which are integrated with charging circuit.

  • Page 8: Audio Input

    Audio Input JAB3+ supports both Bluetooth input and 3.5mm line input. Signals from the two input methods will be mixed before being transmitted to the amplification circuit. AUX IN JAB3+...
  • Page 9 Audio Input 3, Bluetooth input JAB3+ is integrated with Bluetooth 5.0 module, supporting various audio formats as apt-X, aptX HD, apt-X LL, SBC & AAC . There is a built-in Bluetooth antenna on the board for stable connection. So you can directly use JAB3+ for audio playback.
  • Page 10 Audio Input 3, Bluetooth input JAB3+ is integrated with Bluetooth 5.0 module, supporting various audio formats as apt-X, aptX HD, apt-X LL, SBC & AAC . An external Bluetooth antenna port is also provided, which ensures the stability even if JAB3+ is installed in a cabinet.
  • Page 11 Audio Input 4, 3.5mm AUX IN – J9 JAB3+ supports line input and J9 is used for 3.5mm AUX IN. You can get the 3.5mm AUX-IN cable in the Functional cables kit for JAB3+ (AA-JA11117).
