DocumentDocumentWhat 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. Connection Steps Step 1: Connect JAB3 & JAB2 Audio connection Control connection Step 2: Audio input JAB2 BT / 3.5mm AUX IN / Interface board JAB3 3.5mm AUX IN Step 3: Audio output Speaker Step 4: External LED and control External LED Control ports Step 5: Power supply Power Adapter Battery board Connect JAB3 & JAB2 J5 J12 JAB3-1100 J11 JAB2-250 · 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*; *Note J5 1 When JAB2 is used separately, for normal playback, two jumpers are required if external volume potentiometer is not connected. J9 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. Audio Input JAB2 AUX IN J6 JAB2 BT Input JAB3 AUX IN This audio system supports Bluetooth or AUX input. If customers want AUX IN, there are J6 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 LED and Control J18 J7 J5 J8 J6 · 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 Supply Power adapter · Separate power: JAB3 and JAB2 can be powered by separate power adapter; · Power by one power adapter: It is recommended to use one power adapter to power JAB3 and JAB2 and the connection is as follows. JAB2 JAB3 Red to Red Black to Black Power Supply Power by Sure Electronics Battery baord (AA-JA11113) J8 . . . Sure Electronics Battery Balance and Protection Board provides multiple discharging ports with same function. Customers can use AA-JA11113 to J1 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. Functions of Potentiometers Potentiometers of JAB3 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 integrat ed circuit output of 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 (AAJA32473); JAB3M refers to JAB3 in mono mode, namely 1 x 100 Watt Class D Audio Amplifier Board w DSP - JAB3 (AA-JA31181) or 1 x 60 Watt Class D Audio Amplifier Board w 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, ple ase contact us at store@sure-electronics.com. Sure Electronics Co., Ltd.
