Product details
JAB3+ is audio amplifier board integrated with Bluetooth 5.0 (supporting aptX HD) and ADAU1701 DSP, offering a real all-in-one audio solution for customers. JAB3+ covers 2 x 50W, 2 x 30W, 1 x 60W and 1 x 100W four models. Thanks to the equipped ADAU1701 DSP, JAB2 supports programming with SigmaStudio, APP control and PC UI control after connection with WONDOM ICP3 or higher version(s), through which, you can adjust volume, gain, frequency and EQ setting to customize your own audio. In addition to speaker output, JAB3+ offers an extra mixed signal output, which can be input to other audio amplifier board to build audio 2.1 / 4.0 system. You can set it as stereo or mono with PC UI according to the connected amplifier board. Besides power supply, JAB3+ supports battery power, which greatly improves the portability. Wireless audio input, integrated ADAU1701 DSP, battery power, light weight and high quality audio performance make JAB3+ perfectly suitable for portable Bluetooth speakers, home audio, garden audio and DIY applications. A DC12V-26V power supply is required.
Integrated with Bluetooth 5.0 module
JAB3+ employs Bluetooth 5.0 module for audio input, which supports various audio formats as aptX, aptX HD, aptX LL, SBC & AAC and high receive sensitivity with RF power up to 9dBm and -90dBm. There is a built-in antenna equipped on this board. So you can directly pair JAB3+ with the device to play music. An external antenna port is also provided on the board to ensure the stable connection and high audio performance in such applications that JAB3+ is installed into a speaker or a cabinet.
Integrated with ADAU1701 DSP, Supporting Programming with SigmaStudio, APP and PC UI control
JAB3+ is also integrated with high performance ADAU1701 DSP chip for audio signal processing. Four ports for external potentiometers are mounted on JAB3+. You can use the external potentiometers to control the volume, gain and frequency even if JAB3+ is installed in a speaker. After connection with WONDOM ICP3 or higher versions, you can write a program with SigmaStudio, or get real-time remote control of your audio systems via APP or PC UI, through which, you can adjust gain, volume, high/low-pass filter, EQ and other parameters.
Supporting Line Input
In addition to Bluetooth input, JAB3+ supports 3.5mm line input. Signals from the two input methods will be mixed before being transmitted to the amplification circuit. You can get the 3.5mm AUX-IN cable in the Functional cables kit for JAB3+ (AA-JA11117).
Supporting Battery Power
Beside power supply, JAB3+ supports battery power, which greatly improve the portability of the systems. Please note, since JAB3+ is not equipped with charging circuit, it is recommended to use WONDOM BCPB series battery boards, which are equipped with charging circuit, to power JAB3+.
Cascading with Other boards to Build Audio 2.1 systems
JAB3+ provides a line output signal. An extra audio amplifier is required to connect with speakers for playback as it is an audio signal output. The output mode of this line output signal (stereo or mono) can be configured by customers according to the connected board through SigmaStudio or APP. Therefore, you can build an audio 2.1 system to your requirements. Fully considering the easy control and audio performance of the built audio system, Sure Electronics prepares a synchronization port on JAB3+ to ensure the control logic of the two boards are consistent. It is suggested to cascade standard audio amplifier boards whose AMP chip is TPA311x with JAB3+ for better connection and sound quality.
High Expandability and Playability
After providing the analog and digital I/Os of JAB3+, there are still pins available on ADAU1701. We have extended 10pins as extension port. You can develop JAB3+ to build your unique applications with this port. As for the mapping of ADAU1701, please refer to the datasheet. Many customers are interested in I2S input and output, therefore we configure this port to be applicable to I2S input and output.
Signal Level Sensor System
JAB3+ employs signal level sensor system for lower power consumption and longer playback time. It will continuously monitor the input signal and there is a preset signal voltage threshold. When there is no signal (voltage is lower than the threshold) detected for 5min, the amplifier module will enter into standby mode automatically, in which condition, it will consume lower power. When there is signal detected, it will run immediately without any miss of the audio.
Easy for Integration
Bluetooth pairing cancellation function is integrated on JAB3+. You can disconnect with Bluetooth by one simple press, without worry about which Bluetooth is paired. Standby function is also available on JAB3+. Ports for External LED indicators are offered to show the status of Bluetooth and signal, so you can have an overview of the running condition of JAB3+.
Optional Accessories
We provide optional accessories for customers’ simple operation. With 9.14cm x 6.86cm L-style bracket (AA-JA11115), you can immobilize JAB3+ in connection and installation stage. Functional cables kit (AA-JA11117) offers all the cables you need for better use of JAB3+. As for the detailed information, please refer to AA-JA11117.
