Ure Jab3 User manual

What is JAB3?

JAB3 are audio amplifier boards integrated with ADAU1701 DSP, covering four models as stereo 50W, stereo

30W, mono 100W and mono 60W. Four potentiometers are pre-mounted on JAB3 for easy control of the audio

system, through which, customers can adjust volume, high-pass filter and gain. Please refer to the datasheet for

detailed information.

In addition, with connection with stereo or mono JAB2, customers can get audio 4.0/2.1 system integrated with

both DSP and Bluetooth.

It is recommended to use MONO JAB3 as 0.1 when building audio 2.1 system.

Thanks to equipped DSP, JAB3 is suitable for active loudspeakers

to achieve digital 3 way 3 unit, 2 way 2 unit crossover and bass

enhancement, applicable to the studio.

This document aims to provide connection guide for JAB3 and

JAB2 by taking the example of building an audio 2.1 system.

The steps for audio 4.0 system are the same.

Control ports

•Audio connection connect J5 of JAB3 and

J11 of JAB2 with a 6pin cable*;

•Control connection connect J12 of JAB3

and J9 of JAB2 with a 3pin cable*;

Connect JAB3 & JAB2

*Note

1 When JAB2 is used separately, for normal playback, two

jumpers are required if external volume potentiometer is not

connected.

2 When JAB3 is used separately, J12 is for control cable.

Please do not short circuit ‘MUTE’ and ‘GND’ under any

circumstance.

3 When JAB3 is connected with JAB2, J5 of JAB2 is used as

control port for audio system.

4 Sure Electronics provides matched Functional Cables Kit

for JAB3 and JAB2 connection for customers’ easy operation.

JAB2 AUX IN

JAB3 AUX IN

This audio system supports Bluetooth

or AUX input.

If customers want AUX IN, there are

two ways:

•3.5mm AUX IN

Connect 5pin AUX IN cable to J6 of JAB3

/ JAB2

•AUX IN port of Interface board

Connect Interface board to J6 of JAB2

with a 10pin cable.

Note: Interface board can only be connected with

JAB2.

Audio Output

The speaker of the audio 2.1 system is shown right.

Stereo:

Take speaker output of JAB2 as stereo;

Subwoofer:

Take speaker output of JAB3 as subwoofer;

Headphone Output:

Take J3 of JAB3 as headphone output.

External LED and Control

•External Bluetooth LED: J7 of JAB2

•External Charge LED: J8 of JAB2

•External Power LED : Pin 3,4 of J6 of JAB2

•External Bluetooth Control: J18 of JAB2, long press to

turn on/off BT, short press to cancel paring

•External Shutdown Control: J5 of JAB2, short circuit

‘EN’ and ‘GND’ to shutdown audio system

Power adapter

•Separate power: JAB3 and JAB2 can be

•Power by one power adapter:It is

recommended to use one power adapter to

power JAB3 and JAB2 and the connection is as

follows.

Sure Electronics Battery Balance and

Protection Board provides multiple

discharging ports with same function.

Customers can use AA-JA11113 to

power JAB3 and JAB2 simultaneously.

The connection is shown left.

Note:

1 The charging circuit is equipped in JAB2 instead

of AA-JA1113. If customers want to charge batteries

with AA-JA11113, JAB2 is requisite. Please connect

power adapter and battery board to JAB2 at the

same time to charge batteries.

2 Two or more pcs battery balance and

protection boards can be connected in parallel for

higher capacity, while the output voltage will not

increase.

Potentiometers of JAB3

Functions of Potentiometers

Functions of potentiometers based on specific applications

Note:

1. The speaker output (J10) of the board with potentiometers is defined as CH1; 3.5mm headphone output (J3)or other integratedcircuit outputof the board with potentiometers is

defined as CH2.

2. JAB3S refers to JAB3 in stereo mode, namely 2 x 50 Watt Class D Audio Amplifier Board w DSP - JAB3 (AA-JA32172) or 2 x 30 Watt Class D Audio Amplifier Board w DSP - JAB3 (AA-

JA32473); JAB3M refers to JAB3 in mono mode, namely 1 x 100 Watt Class D Audio Amplifier Boardw DSP - JAB3 (AA-JA31181) or 1 x 60 Watt Class D Audio Amplifier Boardw DSP -

JAB3 (AA-JA31211).

3. HPF refers to High-pass Filter; BPF refers to Band-pass Filter.

When CH1 is stereo output, the function of POT3 is HPF; when CH1 is mono output, the function of POT3 is BPF.

4. Four applications are exampled in this datasheet. For the functions of potentiometers when used in other applications, please contact us at store@sure-electronics.com.
