The Wondom JAB3+ is an amplifier module capable of developing a power of 1x60W, supporting Bluetooth 5.0 (aptX HD) and integrating an ADAU1701 DSP for an all-in-one audio solution. Thanks to the latter, the JAB3+ can be programmed with SigmaStudio and AppControl via an intuitive graphical interface (requires the use of a Wondom ICP5 module, not supplied).

In addition to its speaker output, the JAB3+ has an additional mixed audio output that can be used with another amplifier module to create a 2.1 or 4.0 system. The PC interface then allows the amplifier to be configured in mono or stereo mode. In addition, the JAB3+ can be battery-powered to create a portable, high-performance audio system.

Bluetooth 5.0

The JAB3+ uses a Bluetooth 5.0 module as input, supporting AAC, SBC, aptX, aptX LL and aptX HD codecs and enjoying a high reception sensitivity of up to 9dB and -90dBm. This makes it possible to pair the JAB3+ with an audio source. An external antenna port is also available in case the JAB3+ is installed in a box.

DSP ADAU1701

The JAB3+ therefore embeds an ADAU1701 DSP chip for audio signal processing. Four ports allow to mount external potentiometers (sold separately). These will allow you to control volume, gain, bass and treble levels. When used with a Wondom ICP5 module (sold separately), you can adjust many audio parameters via the SigmaStudio software or a control application.

Line input

In addition to the Bluetooth input, the JAB3+ offers a line input. The signal from both inputs can be mixed before being transmitted to the amplifier circuit.
