JAB3 – 250 is an All-in-one stereo Class D audio amplifier board integrated with high performance DSP – ADAU1701, outputting 50W per channel into a 4Ohm load based on Texas Instruments TPA3116 chip. With the integrated DSP chip, JAB3 can be applied to various DIY audio, commercial or industrial applications such as digital crossover, bass enhancement, loudspeakers, kiosk, etc. After connection with WONDOM programmer – ICP series, JAB3 supports programming with SigmaStudio, remote control through APP or PC UI.

Integrated with ADAU1701 DSP, Supporting SigmaStuio Programming & APP Control

The on board fully programmable 28-/56-bit audio DSP ADAU1701 from Analog device is competent in various signal processing applications. This process can compensate for real-world limitations of speakers, amplifiers, and listening environments, providing dramatic improvements in perceived audio quality.

Four potentiometers are provided on JAB3 for real time hardware control of the whole audio system for volume, gain and high / band pass filter.

Thanks to the integrated ADAU1701 DSP, JAB3 supports multiple control methods. JAB3 is mounted with four on-boards potentiometers, which are for volume and frequency adjustment. After connection with WONDOM ICP series (ICP1, ICP3, ICP5) programmer, JAB3 supports programming through SigmaStudio. In addition, if you connect JAB3 with ICP3, you can use APP to remote control your audio systems.

APP Miumax

Android: Please download it in the "Files&Videos" part.
iOS: Please go to APP Store and search “Miumax” directly.
To enable APP control, JAB3 requires a specific DSP program. You can find the required file in the 'Files&Videos' section.

High Quality Audio Performance

Thanks to dedicated PCB layout design and engineers’ attentive debugging, this JAB3 - 250 audio amplifier board features high audio performance, whose SNR is 88dB and THD+N performs well as 0.04% @ 4Ohm, 5W, 1kHz.

Low Power Consumption and Long Playback Time

Power management system and Signal level sensor system are employed on JAB3 for low power consumption. We have preset a threshold on the input voltage of the signal. When there is no signal detected in 5min, JAB3 would enter into standby mode automatically.
This JAB3 - 250 audio module dissipates only 120mW in standby mode. The extremely low power consumption ensures long playback time especially when JAB3 - 250 is powered by battery boards, which is absolutely an advantage for portable Bluetooth speakers.

Supporting Battery Power

A DC10V-26V power supply is required to power JAB3 - 250.
In addition to power supply, JAB3 also supports battery power, which greatly improve the portability and flexibility of audio systems.

Please kindly noted that MPPT circuit is not employed in JAB3. So JAB3 cannot be used to recharge batteries. If you only buy JAB3 and want portable battery power, it is recommended to use WONDOM Battery charging, protection and balance board – BCPB series. If you have a JAB1 / JAB2 at hand, you can use the WONDOM Battey charging and protection board (JAB – BE, AA-JA11113) for power.

Easy for Installation

Four screw holes provided make this Bluetooth amplifier board easy for installation and quick for integration in any cabinet. We provide a Functional cables kit (JAB - FC) for your convenient operations. Furthermore, a 3.6’’ x 2.7’’ L-style aluminum bracket (JAB - LAB) is available to fix the Bluetooth amp in wiring process and to install the board to cabinets.



Build Audio 2.1/4.0 system with Bluetooth and DSP

JAB2 can connect with mono JAB3 to build an audio 2.1 system or connect with stereo JAB3 to build an audio 4.0 system. This built system will be integrated with both Bluetooth and DSP, suitable for portable Bluetooth speakers and digital crossover applications. A Functional cables kit (AA-AJ11116) is released for your convenient connection. As for the connection, please kindly take the .
