Description

JAB2 - 1100 is a mono audio amplifier board integrated with Bluetooth V4.0, delivering 100W output power into a 2Ohm load based on Texas Instruments TPA3116 chip. JAB2 - 1100 offers a high efficiency wireless solution for customers, suitable for portable speakers, Bluetooth speakers, subwoofer, home audio, DIY audio, hotel, kiosk, industrial audio, etc. An optimized heatsink is mounted atop the amplifier board to maximum heat dissipation for higher efficiency. Compact size and light weight make JAB2 applicable to almost any audio projects.

Integrated with Bluetooth

JAB2 is integrated with high performance Bluetooth module, which means you can connect JAB2 with any portable devices or PC to easily access streaming audio via Bluetooth paring. In addition, the module supports changing Bluetooth name, so you can customize your name of JAB2.

JAB2 also supports 3.5mm AUX IN. The line input and Bluetooth input would be mixed to the amplification circuit.



High Quality Audio Performance

Thanks to dedicated PCB layout design and engineers’ attentive debugging, this JAB2 - 1100 audio amplifier board features high audio performance, whose SNR is 92dB and THD+N performs well as 0.02% @ 4Ohm, 10W, 1kHz.



Low Power Consumption and Long Playback Time

This JAB2 - 1100 audio module dissipates only 0.72W with no signal when in ON mode (around 0.07W when in stand-by mode) due to the employed power management system. The extremely low power consumption ensures long playback time especially when JAB2 - 1100 is powered by battery boards, which is absolutely an advantage for portable Bluetooth speakers.



Multiple Power Path

A DC10V-24V power supply is required to power JAB2 - 1100.

In addition to power supply, JAB2 also supports battery power, which greatly improve the portability and flexibility of audio systems. MPPT circuit is equipped in JAB2, so it can recharge the batteries with a power supply connected.



It is recommended to use WONDOM Battey charging and protection board (JAB - BE) designed for 3pcs 18650 Lithium-ion batteries in series as it’s equipped with full protection circuit for operation safety. A 15V-24V, 1A-5A power supply would be required for the purpose to fully charge the batteries.



If you use rechargeable lead acid batteries, a 15V-24V, 1A power supply is needed.

You could also use solar panels for their applications. Just remember to use solar batteries with float (open) voltage with 16.5V-21.5V, and use 20-100W panels for this application.

8 AA (Alkaline) Batteries in series will be 12V to power the amplifier. Please note that AA batteries couldn’t be connected with charging port unless MPPT module is removed.



Bluetooth Control

There is a Bluetooth control port on the JAB2. With a short press on the control button, you can cancel the Bluetooth pairing. With a long press, you can turn OFF / ON Bluetooth. Please note that the Bluetooth control button is not the basic cable in the package. If you want this cable, please buy the Functional cables kit for the connection between JAB2 with JAB3 (AA-JA11116).



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, the speaker out connection information is different in the PDF and on your web page (JAB2 AA-JA31182). It seems that the web page is correct. Could confirm the connection configuration and how to connect the single speaker with the 4 connection? Thank you.

Hi, Bernard. Thank you for your interest in our products. Please kindly see the attached picture for reference. Wish this could help you.

Can i connect this with the jab3 100watt board to make a 2x100watt dsp bluetooth amp?

Hi, Alex. Yes. You can connect JAB3 - 1100 and JAB2 - 1100 to make a 2x100W system with DSP and Bluetooth. Please kindly be noted that you need to configure the output DAC with the SigmaStuido by yourself. You can download the demo program and configure based on that. Wish this could help you.

Hello, i wonder if i can use this amp with a 5S lithium protection board. My question is, do i have to buy the BCPB3 without charging or the BCPB4 with charging? Aka does this amp have charging possibilities?

Hi, Marcus. Thank you for your interest in our products. You can use BCPB3/BCPB4 to power JAB2-1100. The charging circuit employed in JAB2 only works for 3S 18650 battery board without charging function. If you want to charge BCPB3/BCPB4, please connect BCPB3/BCPB4 with a power supply whose voltage is within the recommended range. Wish this could help you.
