3.5mm AUX analog and Bluetooth input channels are configured flexibly; the volume is adjusted by the external
poten�ometers; 3 output power level versions are provided as 2 x 15W, 2 x 30W and 2 x 50W, which are listed at
the price as $19.9, $29.9 and $34.9. Various accessories including interface extension board, ba�ery balance and
protec�on extension board, func�onal cables package and L-style aluminum bracket provide more func�onal
features and convenient installa�on method. For more detailed price informa�on, please refer to Price List
chapter. We will provide the JAB series at the most compe��ve price with the approach of no compromise for

High Performance Cost Ra�o
The amplifier board series employs the TPA311x series
from TI as the main chip. All of them are equipped with
overcurrent and overtemperature protec�on, which is
able to avoid permanent stress caused by improper
opera�on.
Besides built-in chip protec�on, ESD and spike
protec�on components are used throughout input and
output of the amplifier board to ensure its robustness
and reliability. And all the available input and output
pins are presented as Molex headers which facilitate
ma�ng and prevent accidental mismatching during
assembly
.
Full Protec�on,
Robust Performance
JAB2 provides a stereo solu�on for portable Bluetooth speakers
with MPPT ba�ery charging. Sure Electronics offers audio
4.0/2.1/0.2 system solu�on for customers through connec�ng
JAB2 with JAB3, which is integrated with DSP. This means,
when working with JAB3 main boards, it is a complete 4.0
(Both JAB2 and JAB3 are stereo mode.), 2.1 (One board is
stereo mode and another is mono mode.) and
0.2
(Both JAB2
and JAB3 are mono mode.) audio system with control
interfaces and signal processing.
The applica�on ranges from
ac�ve louderspeaker concepts (digital 3 way 3 unit, 2 way 2
unit crossover, bass enhancement, etc.) and realize the
transforma�on from 2.0 to 2.1 (when used with JAB3).
With integrated debug port for Sigma Studio on JAB3,
customers can pre-program with Sure Electronics ICP1, ICP2 or
the original Analog USBi to get more func�ons which includes
equaliza�on, crossover, bass enhancement, mul�band
dynamics processing, delay compensa�on, etc. For detailed
informa�on, please refer to JAB3 Brochure.
Customers can connect the JAB3 with JAB2 via the JST-PH-6PIN
connectors on board.
For more detailed connec�on informa�on, please refer to the
installa�on guide for JAB2 and JAB3 connec�on.
