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 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, 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 ICP3 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.

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.

Hello, what power output could it be at 12V and 6ohm ?

Hello, olivier. The output power is approximately 12W per channel when driving 6Ohm at 12V. Wish this could help you. Have a nice day~

Hello. Is it possible to use SigmaStudio to program the DSP on JAB2V2 (with ICP5)? Or, is it possible to program separate EQ settings on the left and right channel using PC UI?

Hello, Colin. Thank you for your interest in our products. JAB2v2 does not support program through SigmaStudio. It only supports PC UI control after connection with ICP5. You can adjust the EQ settings of stereo via PC UI. It does not support separate EQ adjustment of left and right channel. Wish this could help you.

A few years ago, I bought an AA-JA32473 unit believing it to be a bluetooth amplifier. It was a project that I had pending. Yesterday I decided to start the project and what was my surprise when I verified that this circuit did not have bluetooth. I have seen on the web, that you can combine a JAB2 with a JAB3. My question is: Is this version of JAB3 compatible with the new version of JAB2.

Hi, Antonio. AA-JA32473 is JAB3 - the amplifier board integrated with DSP. Yes. JAB3 can be connected with JAB2v2. Wish this could help you.

Hello I want to buy a unit of 2 X 30 WATT CLASS D AUDIO AMPLIFIER BOARD W BLUETOOTH VER5.0 & DSP - JAB2V2 - 230 [759]. You also need to purchase Cables Package for JAB (JAB accessories).

Hi, Antonio. Thank you for your interest in our products. A power cable and speaker cable come with JAB2v2 for basic connection. I noticed that you buy this JAB2v2 to connect with JAB3. If so, it is suggested to buy the matched cables kit, which is specially for JAB3 and JAB2 connection. https://store.sure-electronics.com/product/AA-JA11116 Wish this could help you.

Hello, I want to buy 2 X 30 WATT CLASS D AUDIO AMPLIFIER BOARD W BLUETOOTH VER5.0 & DSP - JAB2V2 - 230 [759]. Is it necessary to purchase the Cables Package for JAB (JAB accessories), with the bluetooth antenna? Thanks

Hi, Antonio. Thank you for your interest in our products. There is a built-in Bluetooth antenna on JAB2v2, so you can use it directly without an external antenna. If you want to install JAB2v2 into a cabinet, it is suggested to connect with the external antenna. BTW, If you want external LED indicator, external volume control, Bluetooth pairing cancellation and other cables, it is suggested to buy the cable kit. Wish this could help you.

Hey, It appears that there is some active noise reduction integrated, which reduces the volume of quiet tons in the music. This results in sudden change of the volume. Is there a way to turn this of?

Hi, Fynn. This can be adjusted through PC UI after connection with ICP5. The release of ICP5 has been delayed due to the shortage of the chip and the resulted long lead time. We are trying our best to release it ASAP. Wish you could understand us.

Hey, I have got the JAB2V2 (2x30W) and I want to connect it with my ICP3 for PC UI Control. Is there an Adapter from PH-4POS-2mm to PH-6PIN-2mm? Or an other solution to connect them? Thanks!

Hi, Fynn. Please note that JAB2v2 cannot be connected with ICP3. It can only work with ICP5 for PC UI control. Due to the shortage of chip and resulted long lead time, the release of ICP5 has been delayed. We will try our best to release it ASAP. Wish this could help you.
