Description
JAB2V2 is audio amplifier board integrated with Bluetooth 5.0 (supporting aptX HD) and DSP, offering a real all-in-one audio solution for customers. JAB2V2 covers 2 x 50W, 2 x 30W, 1 x 60W and 1 x 100W four models. Thanks to the equipped DSP chip, JAB2V2 supports PC UI control after connection with WONDOM ICP5 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, JAB2V2 offers an extra mixed signal output, which can be input to other audio amplifier board to build audio 2.1 / 4.0 system. Customers can configure it into a subwoofer signal by frequency adjustment in PC UI. Besides power supply, JAB2V2 supports battery power, which greatly improves the portability. Wireless audio input, battery power, light weight and high quality audio performance make JAB2V2 perfectly suitable for portable Bluetooth speakers, home audio, garden audio and DIY applications. A DC10.8V-24V power supply is required.

--------------------------------------------------------------------------------------------
Integrated with Bluetooth 5.0 module
JAB2V2 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 JAB2V2 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 JAB2V2 is installed into a speaker or a cabinet.
Supporting Line Input
In addition to Bluetooth input, JAB2V2 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 (AA-JA11114 / AA-JA11116).
Integrated with DSP, Supporting PC UI
Taking customers’ reviews and feedbacks into account, we integrate DSP chip on JAB2V2. Programming port is provided on JAB2V2. After connection with WONDOM ICP5 or higher versions, you can get PC UI control function. Sure Electronics has developed a PC UI, with which, you can try with gain, high/low-pass filter, noise suppressor, bass, frequency shifter and many other effects. ICP5 is under test now and will be released soon.
Supporting Battery Power
Beside power supply, JAB2V2 supports battery power. What’s more, JAB2V2 is equipped with MPPT charging circuit. So you can use 3S Lithium battery board (AA-JA11113) to power JAB2V2. When you want to charge batteries, connect the battery board (AA-JA11113) with JAB2V2 and connect a power supply with JAB2V2 at the same time. It is suggested to use a power supply whose output voltage is within DC15-24V and current is higher than 1A to charge batteries.
Mixed Line Output Signal, Supporting configuration as subwoofer
JAB2V2 provides a mixed line output signal, which can be transmitted to other WONDOM audio amplifiers to build an audio 2.1 / 4.0 system. Please note that it’s audio signal, so an amplifier board is required for connecting with a speaker. It is suggested to connect JAB2V2 with JAB3 to build audio 2.1 / 4.0 system. In this condition, it is recommended to use DSP of JAB3 for system control.
Easy for Integration
Bluetooth pairing cancellation function is integrated on JAB2V2. You can disconnect with Bluetooth by one simple press, without worry about which Bluetooth is paired. Shutdown function is also available on JAB2V2. Once you shutdown JAB2V2, JAB2V2 will power off. Ports for External LED indicators are offered to show the status of Bluetooth, power and charging, so you can have an overview of the running condition of JAB2V2.
Optional Accessories
We provide optional accessories for customers’ simple operation. With 3.6’’ x 2.7’’ L-style bracket (AA-JA11115), you can immobilize JAB2V2 in connection and installation stage. You can connect JAB2V2 with the Interface extension board (AA-JA11112) to get a 3.5mm line input port, 2 USB discharging ports with 2.1A maximum current per port, a power switch and indicators for power and mute. Functional cables kit (AA-JA11114) offers all the cables you need for better use of JAB2V2.
