Sure Electronics JAB5 Instruction Manual

BY SURE ELECTRONICS CO., LTD.

What is JAB5?
JAB5 is a four-channel audio amplifier board integrated with high performance Bluetooth 5.0
(Supporting APT-X HD) and ADAU1701 DSP, which delivers 100W per channel into a 6Ohm load. With
employed signal level sensor system and power management system, JAB5 features low power
consumption and high efficiency, suitable for home audio, DIY audio, Bluetooth speakers and digital
crossover applications.
JAB5 supports Bluetooth input, line input and I2S input. Signal would be mixed and delivered to
speaker output.

What is JAB5?
JAB5 supports 4.0 mode (4 x 100W), 2.1 mode (2 x 100W + 1 x 200W) and 2.0 mode (2 x 200W).
The switching between the three modes are achieved by automatic cables identification, without any
need of other operations. Furthermore, JAB5 supports cascading with another JAB5 to get 8 x 100W
or other audio systems through the I2S output port.
Four ports are provided for external potentiometers to control the volume, gain and frequency. With
the connection of ICP5 or higher version(s), customers can achieve programming DSP through
SigmaStudio or remote control with APP or PC UI.
Key Features:
-Integrated with Qualcomm/CSR QCC 3034, Bluetooth V5.0 w
aptX HD & ADAU1701 DSP
-Supporting I2S input, line input, I2S output
-Supporting programming with SigmaStudio or remote control
via APP or PC UI
-Cascadable with another JAB5 to build an 8.0 Audio System

Power Supply
1
Suggested power supply should be 350W, DC36V. You can also use
any power supply whose output voltage is within DC10-39V and
current is higher than 4A. Please note power supply out of the
recommended range may cause damage to the amplifier board.
We recommend 350W Single Output Switching Power Supply LRS-
350 Series. We also recommend Mean Well GST-160A 36V version.
The terminal interface used for power supply is Molex MiniFit-
2x2Pos-4.2mm.
A power supply cable is in basic cable, which comes as a standard
accessory with JAB5 in the package. You can connect the cable to
Mean Well GST-160A.

Audio Input
JAB5 supports three inputs: BT 5.0, I2S input and analog line input, which makes it suitable for various
audio projects. All signals would be mixed.

2. Bluetooth input
2JAB5 is integrated with Bluetooth 5.0 module,
supporting various audio formats as apt-X, aptX HD,
apt-X LL, SBC & AAC .
Note: The device used with this hardware needs to
support the following Bluetooth Audio Codec. Devices
that are not aptX HD compatible will not have the
option available on the UI. All Apple devices are not
compatible with aptX HD.
There is a built-in Bluetooth antenna on the board for
easy connection. So you can directly use JAB5 for
audio playback.
You can find the IPX to SMA conversion cable and
external antenna in the Functional Cables Kit.

5. Stereo speaker output –J13, J14
JAB5 works as 4 x 100W. It also supports configured as 2.0 /
0.2 mode (2 x 200W) or 2.1 mode (2 x 100W + 1 x 200W).
The switching is achieved by automatic cables
identification.
If you want to use JAB5 as 0.2 mode, you need to set
frequency in the PC UI. 0.2 mode is not supported when
using hardware control.
The terminal blocks used for speaker output is Molex-
MiniFit-2x3Pos-4.2mm.
Two speaker cables come with JAB5 as the basic cables.

6. I2S output –J7
Besides speaker output, JAB5 provides I2S
output, which can be transmitted into
another I2S amplifier board.
You can connect 2 JAB5 to build an 8 x
100W audio system.
A switch is provided on JAB5 to set as
master mode or slave mode.

If JAB5 receives I2S from other device, it
must be set as slave mode through the
SW1 provided on board.
If JAB5 provides I2S signal to other device,
it must be set as master mode through the
SW1 provided on board.

LED Indicator
8. Bluetooth LED indicator –J1
When Bluetooth is paired, the LED will be ON;
When Bluetooth is searching, the LED will BLINK.
9. Signal Detection LED indicator –J12
Signal level sensor system is employed in JAB5 for lower
power consumption. Therefore, JAB5 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.
Note: Take definition for J1 and J12 from data sheet.

11. Control Synchronization Port –J10
JAB5 supports cascading with another JAB5
to get 8 x 100W or other audio systems.
This control synchronization port is provided
to make sure the control logic of two
connected boards are consistent, so that the
built audio systems eliminate “POP” noise
and offer simple control.
Please do not use J10 when JAB5 is used
separately.
