Sure Electronics JAB3+ Instruction Manual

BY SURE ELECTRONICS CO., LTD.

What is JAB3+?
JAB3+ is audio amplifier board integrated with high performance Bluetooth 5.0 (Supporting various
audio formats as apt-X, apt-X HD, apt-X LL, SBC & AAC) and ADAU1701 DSP, supporting battery
power, suitable for portable Bluetooth speakers, hotel audio, home audio, DIY applications and
digital crossover applications.
JAB3+ supports both Bluetooth input and 3.5mm AUX IN. Signal would be mixed before being
delivered to ADAU1701 for audio processing. Besides speaker output, JAB3+ supports cascade with
WONDOM standard amplifier boards to build audio 4.0/2.1 systems.

What is JAB3+?
Four connectors for external potentiometers are pre-mounted on the board for easy control of
audio system in case of you want to integrate JAB3+ in a cabinet. In addition to hardware control,
with the connection of WONDOM ICP3 or higher versions, JAB3+ supports programming with
SigmaStudio or remote control through APP or PC UI.
Signal Level Sensor System, Power Management Circuit and full protection are equipped in JAB3+
for lower power consumption, higher efficiency and stable operation.

Power Supply
11, Power supply –J8
Suggested power supply should be 19V 2.1A. You can also use
any power supply whose output voltage is within DC12-26V and
current is higher than 1A. Please note power supply out of the
recommended range may cause damage to the amplifier board.
The terminal interface used for power supply is Molex MicroFit-
2Pos-3mm.
A power supply cable is the basic cable, which comes with JAB3+
in the package.

2, Battery board –J6
Besides power supply, JAB3+ supports battery
power which greatly improves the portability.
There is no charging circuit equipped on JAB3+.
If you want to power JAB3+ with battery
power, it is suggested to use WONDOM BCPB
series, which are integrated with charging
circuit.

JAB3+ supports both Bluetooth input and 3.5mm line
input. Signals from the two input methods will be
mixed before being transmitted to the amplification
circuit.

JAB3+ is integrated with Bluetooth 5.0
module, supporting various audio
formats as apt-X, aptX HD, apt-X LL,
SBC & AAC .
3, Bluetooth input
There is a built-in Bluetooth antenna
on the board for stable connection.
So you can directly use JAB3+ for
audio playback.

An external Bluetooth antenna port is
also provided, which ensures the
stability even if JAB3+ is installed in a
cabinet.

JAB3+ supports line input and J9 is used for 3.5mm AUX IN.
You can get the 3.5mm AUX-IN cable in the Functional
cables kit for JAB3+ (AA-JA11117).

Audio Output

5, Speaker Output –J10
JAB3+ includes four models, 2 x 50W, 2 x 30W, 1 x 100W and 1 x 60W.
2 x 30W and 1 x 60W do not have the heatsink and their amplifier chip
is different from that of the 2 x 50W and 1 x 100W.
Speaker output connector is a Molex-MicroFit-4Pos-2x2 3mm.
Take care of the connector polarity definition, if connected incorrectly,
you might damage your speaker, cannot get sound output, or get
incorrect audio phase.
A speaker cable comes with JAB2+ in the package for easy connection.

Audio Output
66, Line output –J7
JAB3+ provides a line output signal to connect with other WONDOM
standard amplifier boards to build audio 2.1/4.0 system.
The output mode of this line output (stereo or mono) can be
configured by customers through SigmaStudio or APP according to
the connected board.

When Bluetooth is paired, short circuit J3 to
cancel pairing.
After cancellation, please release short circuit.
You can find the Bluetooth pairing cancellation
cable with a button in the Functional cables kit
for JAB3+ (AA-JA11117).
When Bluetooth is paired, press the button for
cancellation.

Based on integrated ADAU1701 DSP, you can
connect JAB3+ with ICP3 or higher version(s) to get
PC UI control, SigmaStudio Control or Bluetooth LE
control.
You can adjust parameters of the audio system to
customize your audio by any of the three methods.

3 MUTE
Short circuit “STBY” and “GND” to enter into standby
mode. Release for normal playback.
“Mute” is for control synchronization with the cascading
amplifier board so that their control logic can be
consistent. Do not short circuit “Mute” and “GND” when
using JAB3+ separately.

When Bluetooth is paired, the LED will be ON;
When Bluetooth is searching, the LED will BLINK.
12, External Signal Detection LED indicator –J11
Signal level sensor system is employed in JAB3+ for lower power
consumption. Therefore, JAB3+ provides an indicator for signal
detection.
When there is signal detected, the LED will be ON;
When there is no signal detected, the LED will be OFF.

To provide customers with more
playability and expandability, we
extended several pins of ADAU1701 as
