JAB3 – 160 is an All-in-one mono Class D audio amplifier board integrated with high performance DSP – ADAU1701, outputting 60W into a 4Ohm load based on Texas Instruments TPA3118 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 DSP

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.

Supporting SigmaStudio Program and Remote Control

Different applications have unlike requirements on audio as the speakers, the environment and the preference are different. To give customers better control of audio systems, Sure Electronics has released In-circuit programmers (ICP series), with connection of which, you can program DSP with SigmaStudio or remote control the system with APP or PC UI.

We have developed an APP – Miumax for remote control, with which, you can adjust volume, gain, frequency and EQ setting. PC UI is also available for different applications as digital crossover, bass enhancement, subwoofer, and so on.

Sure Electronics has provided open-sourced files for customers to start the project quickly. You can download on the “Download” part.

High Quality Audio Performance

Thanks to dedicated PCB layout design and engineers’ attentive debugging, this JAB3 - 160 audio amplifier board features high audio performance, whose SNR is 88dB and THD+N performs well as 0.03% @ 4Ohm, 1W, 200Hz.

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 - 160 audio module dissipates only 150mW in standby mode. The extremely low power consumption ensures long playback time especially when JAB3 - 160 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 - 160.

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 .

Hello, i have one of these boards on the way, but struggle to see where the bluetooth component actually is on this? I bought this purely because it was advertised as an all in one board

Hello, alex. JAB3 - 160 is an all-in-one audio amplifier board integrated with ADAU1701 DSP and it is not equipped with Bluetooth. JAB2v2 is an audio amplifier board integrated with Bluetooth and DSP. We are working on JAB3+ now, which is an audio amplifier board integrated with both ADAU1701 DSP and Bluetooth 5.0. It will be released soon. Please stay tuned.

Hello , the JAB3-160[725] board powred with BCPB2 , has enough power to handle a speaker with 80w rms at 4ohm ,sensibility 92 db ?Thanks

Hi, Simone. Thank you for your interest in our products. When fully charged, the output voltage of BCPB2 can reach 12.6V, in which condition, the output power of JAB3 – 160 would be around 20W@4Ohm. Wish this could help you.

Hello , Iwas wondering if JAB3-160[725] is able to pilot properly a speaker with 80w rms 4ohm sensibility 92 db when connected to 2,83V sine wave test sign Thanks

Hi, Simone. Thank you for your interest in our products. The input sensitivity of JAB3 - 160 is 770mV, that means the amplifier will reach the maximum output power when inputting 770mV signal @ 24V, 4Ohm. 2.873V is too high to input to JAB3 - 160, which would need attenuation to an appropriate value. Wish this could help you.
