- Class D amplifier module Stereo 2x50W with DSP -

Wondom JAB3-30 2x50W

Wondom's Class D JAB3-50 amplifier module delivers 2x50W. With its integrated DSP it is ready to be integrated into your DIY projects.

High-quality audio performance

The JAB3-50 delivers 2x50W power while delivering high-quality sound. The JAB amplifier series incorporates Parallel Bridge Tied Load (PBTL) technology, in which two outputs can be connected together on one channel, enabling higher power and performance.

Compatible JAB1 & JAB2

The JAB1 and JAB2 offer a stereo solution for Bluetooth speakers. The JAB3, in addition to offering a headphone amplifier, incorporate a DSP. This means that when a JAB3 works with a JAB1 / 2, you get a complete audio system 4.0 (BTL), 2.1 and 0.2 (PBTL) with control interface and signal processing.

Integrated DSP

With its built-in debugging port for Sigma Studio (DSP configuration software), you can pre-program new features such as equalizer, crossover, bass enhancement, dynamic multi-band processing, and more. The built-in ADAU1701 28 / 56bit DSP is fully programmable to compensate for the limitations of your speakers, amplifiers or your surroundings and consequently get noticeable sound improvements. The DSP also incorporates two Σ-Δ ADCs and four Σ-Δ DACs with a dynamic range of 98.5dB. Each ADC has a THD + N of -83dB and each DAC a THD + N of -90dB.
