Class D Mono Amplifier Module with DSP 1x100W

WONDOM AA-JA31181 JAB 3-100 Module Amplificateur Class D avec DSP Mono 1x100W

High quality audio performances

The Wondom Class D JAB3-100 amplifier module provides 100W of mono power. With its integrated DSP it is ready to be integrated into your DIY projects such as active speakers. The JAB3-100 delivers a power of 1x100W (mono) while providing high quality sound. The JAB amplifier series incorporates Parallel Bridge Tied Load (PBTL) technology in which two outputs are connected together on one channel, resulting in higher power and efficiency.

Compatible JAB1 & JAB2

Class D Mono Amplifier Module with DSP 1x100WThe JAB1 and JAB2 offer a stereo solution for Bluetooth speakers. The JAB3s, in addition to offering a headphone amplifier, include a DSP. This means that when a JAB3 works with a JAB1/2, you get a complete 4.0 (BTL), 2.1 and 0.2 (PBTL) audio system with control interface and signal processing. Thus, you can use these solutions for active speakers.

Integrated DSP

With its built-in debug port for Sigma Studio (DSP configuration software), you can pre-program new features, such as an equalizer, crossover (frequency redirection), bass enhancement, multiband dynamic processing, etc. The integrated 28/56bit ADAU1701 DSP is fully programmable to compensate for the limitations of your speakers, amplifiers or environment and therefore achieve significant sound improvements. The DSP also integrates two Σ-Δ ADC and four Σ-Δ DACs with a dynamic of 98.5dB. Each ADC has a THD+N of -83dB and each DAC a THD+N of -90dB.

assez génial !
Pour 35€ vous avez un DSP et un ampli classe D tout à fait correct !
On regrettera la très faible documentation Wondom se résumant a quelques vidéos...
La programmation de l'engin est un peu laborieuse et demande le respect d'une procédure pour uploader son programme.
Je l'ai utilisé dans une enceinte bi-amplifiée avec le JAB3 pour les aigus et un T'Amp pour les graves. On peut régler le crossover, mettre en place des limiteurs pour protéger les HP, règler le volume avec un petit encodeur rotatif... Si j'achète un micro de mesure UMIK 1 je pourrais même corriger automatiquement mes HP...
