Wondom JAB3+ Class D Amplifier Board Bluetooth 5.0 DSP ADAU1701 1x100W 4 Ohm
The Wondom JAB3+ is an amplifier module capable of delivering 1x100W of power, supporting Bluetooth 5.0 (aptX HD) and incorporating an ADAU1701 DSP for an all-in-one audio solution. Thanks to this DSP, JAB3+ can be programmed with SigmaStudio and controlled via an intuitive graphical interface (requires the use of a Wondom ICP5 module, not supplied).
Wondom JAB3+: Bluetooth 5.0
The JAB3+ is equipped with a Bluetooth 5.0 module for audio input that supports the aptX, aptX HD, aptX LL, SBC and AAC protocols. This module directly integrates an antenna, so you can pair the JAB3+ directly with the source of your choice to listen to music. An external antenna port is also available on the board to ensure a stable connection in cases where the JAB3+ is installed in a driver or other location requiring the antenna to be offset.
Wondom JAB3+: DSP ADAU1701
The JAB3+ also incorporates a high-performance ADAU1701 DSP chip for audio signal processing. Four ports for external potentiometers are fitted to the JAB3+. You can use external potentiometers to control volume, gain and frequency response.
Once connected to the WONDOM ICP5 programmer, you can write a program with SigmaStudio, or get real-time control of your audio systems via the PC user interface, where you can adjust gain, volume, high/low pass filter, EQ and other parameters.
Miumax ApplicationWondom JAB3+: Jack 3.5mm line input
Furthermore, in addition to the Bluetooth input, the JAB3+ has a 3.5mm jack line input. Note that when the two inputs are used simultaneously, the signals are mixed before being sent to the amplification circuit.
Wondom JAB3+: Battery powered
Moreover, the JAB3+ supports battery power, making it ideal for use on the move. Please note, however, that the JAB3+ is not equipped with a charge management circuit, so we recommend using a battery management module such as the Wondom BCPB6.
Wondom JAB3+: 4 external potentiometers
Four external potentiometer ports are fitted to the JAB3+ for easy control of the entire audio system. You can use them to control gain or crossover frequency with ease. The functions of these potentiometers adjust automatically according to the output mode.
Wondom JAB3+: Automatic standby mode
The JAB3+ uses a signal level detector to reduce power consumption. It constantly monitors the input signal and there is a pre-set signal voltage threshold. If no signal is detected (voltage below threshold) for 5 minutes, the amplifier module will automatically go into standby mode, reducing power consumption. Similarly, when a signal is detected in standby mode, the module will automatically reactivate.
