Class D Stereo Amplifier Module with DSP 2x50W

WONDOM AA-JA32172 JAB 3-50 Module Amplificateur Class D avec DSP Stéréo 2x50W

High quality audio performance

The Wondom Class D JAB3-50 amplifier module provides 2x50W of power. With its integrated DSP it is ready to be integrated into your DIY projects. The JAB3-50 delivers 2x50W of 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, resulting in higher power and efficiency.

JAB1 & JAB2 Compatible

The 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.

Integrated DSP

Thanks to an integrated serial debug port, you can reprogram the integrated DSP in your JAB3 amplifier in order to modify / add new functions. There are two ways to do so (one is really powerful while the other is quick and simple)

SigmaStudio

SigmaStudio is certainly the most complete and powerful solution for ADAU1701 DSP Chip programming (and the most technical as well). This solution lets you set up your JAB3 with many digital processing tools such as equalizers, crossovers (frequencies redirection) specific treatement for low frequencies, multiband dynamics...etc. SigmaStudio is a very powerful tool that can also set specific signal processing algorithms for each channel.

The SigmaStudio method uses a programmation module to flash the DSP internal memory (integrated to JAB3). Once it is done, the JAB module runs the DSP algorithms independent when powered (does not need the programmation module to stay plugged).

This solution is also suited for non-HIFI applications (sound acquisition / synth) that need to use both Σ-Δ ADC and the four integrated Σ-Δ ADC, while enjoying a dynamic range of 98.5dB. Each ADC has a THD+N of -83dB and each DAC has a THD+N of -90dB.

Getting started with SigmaStudio

You will find on this page a guide to discover SigmaStudio and a walkthrough to connect the programming module as an interface between your JAB3 and your computer.

MIUMAX

The app MIUMAX (available on Android) is by far the simplest solution and allow you to set up your JAB3's DSP in a few minutes. This method covers the functions of volume / gain / filters / delay / phase / 10-bands equalization, which is already impressive for a DSP integrated to an amplifier of this size / power.

MIUMAX uses the programming module ICP3 as a remote control which uses your smartphone (or any bluetooth device running on android or IOS) as an interface for DSP configuration. MIUMAX's configuration menu is really easy to understand for beginners.

It is also a very pratical tool for real-time test while being able to move and experience the whole listenning room.

DSP on board und sparsam
Ich finde die Kombonation aus JAB3 + Bluetoothmodul besser als ein JAB2 und DSP zu kombinieren,da man dort ein Step-Down für das DSP benötigt.

Le DSP totalement paramétrable avec SigmaStudio est extrêmement appréciable.
Utilisé pour une enceinte amplifiée à filtrage actif, avec un Dayton DC160-8 et un tweeter de récup, de cela fonctionne très bien.

Qu'elle WattRms
Bonjours, vos produits on l'air fort intéressant mais pour pouvoir y connecter des haut parleur sans faire d'éreur il faudrait avoir une indication en wrms. Car les watt max ne permette pas d'avoir une valeur fiable
... merci
