WONDOM JAB series is integrated with Bluetooth module for wireless audio connection, and DSP module for easy and remote control, widely applicable in Audio DIY applications, like bookshelf speakers, portable speakers, garden audio, etc.
Have you ever encountered this situation? You want to install your audio system outdoor, such as in the garden or on the porch wall. But you have to give up because of the restriction of weather or dust. You are afraid that the audio system would be damaged due to the rain or moisture.
Taking the outdoor applications requirements into consideration, we designed the waterproof cabinet, which is made of ABS plastic and can protects your PCB from moisture or dust. The regulation of the waterproof cabinet is 140 x 103 x 49mm, therefore, any PCB whose dimension is within 127mm x 70mm (LxW) can work greatly with it. There are four pre-drilled holes for wire connection of power supply, LED indicators or control buttons. We have prepared various accessories for your convenient integration, including screws, waterproof connector plug and socket, adhesive tape and so on. This can vastly save your time of preparation and enjoy the pure joy of DIY audio.
Sure Electronics is going to take part in Prolight + Sound Exhibition Guangzhou, which is held in China Import and Export Fair Complex in May 16th – 19 th, 2021. Our boost number is Hall 3.1 H18. We would love to sincerely invite you to visit us!
We are going to exhibit the CVAA series, which is constant voltage amplifier specially designed for mass notification system. CVAA series contains 7 mono or stereo models, all of which can directly output 70V/100V/120V high output voltage, without any need of step-up transformers, saving the cost and improving the audio quality.

With full investigation on requirements on the audio systems of Game machine and self-service equipment, Sure Electronics has released audio amplifier boards specially designed for kiosks, self-service equipment and game machine applications, such as vending machine, ATM, service robot, arcade machine, amusement equipment and so on. We have divided KAB series into four types, Basic audio amplifiers, 4CH audio isolation amplifiers, digital input amplifiers and subwoofer amplifiers.
Basic audio amplifiers with high speech intelligibility
Sure Electronics provides four basic audio amplifiers in compact size as KAB1 ‒ 22, KAB2 ‒ 215, KAB7 ‒ 250 and KAB7 ‒ 2100. Low and medium output power along with high speech intelligibility makes them suitable for most vending machine, self-service robots, ATM and so on. All basic audio amplifiers support single-ended input. Thanks to the pre-mounted industrial grade terminals, KAB series can be integrated into audio systems and cabinets without much training and time.
4CH audio amplifiers
Sure Electronics offers 4-channel audio amplifiers for applications that need multichannel audio. KAB6 and KAB8 can deliver 15W, 30W or 75W per channel, supporting configuration as PBTL mode. Therefore, one product can apply to three audio systems as 4.0, 2.1 and 2.0. Audio isolation circuit is employed in KAB6 and KAB8 to effectively suppress noise. In addition, they support connection with USB codec module, differential input module and DSP module, which greatly improves the flexibility and expandability of the whole system.
Digital input amplifiers
Sure Electronics released several KAB amplifiers for customers who want digital input. All the amplifiers (KAB0, KAB3, KAB4, KAB5 and KAB9) support I2S input, S/PDIF or USB Codec input, in which condition, audio signal will be transmitted in digital form, avoiding the ground noise.
Sure Electronics provides three amplifiers in PBTL architecture as 0.1 subwoofer, which delivers 40W, 80W and 300W output power and can be used with other KAB amplifiers. All the subwoofer amplifiers support I2S, S/PDIF, high voltage differential input and RCA input.
If you are interested in KAB series, please contact us with firstname.lastname@example.org.
KAB series is a highly cost-effective amplifier board series specially designed for kiosks, self-service equipment and game machine applications, such as vending machine, ATM, service robot, arcade machine, amusement equipment and so on.
KAB8 is a 4CH audio amplifier board, providing 30W / 70W output power per channel. KAB8 features high reliability because of the fully equipped protection circuit. Audio isolation circuit is also employed for higher audio performance.
Suitable for audio 4.0/2.1/2.0 systems
KAB8 supports PBTL configuration, which means every two channels can be modified to mono channel with double power, making it suitable for commonly used audio 4.0 / 2.1 / 2.0 systems in game machine applications. For example, KAB8 – 430 can be configured as 4 x 30W, 2 x 30W +1 x 60W or 2 x 60W. One product, multiple configurations for different applications, which is highly cost-effective.
Customers can simply choose the three modes through the switch provided on KAB8.
Supporting 4CH USB codec integrated with DSP
Taking the ground noise caused by single-ended input, Sure Electronics has developed a 4CH USB codec for KAB8. It is in module form, therefore it’s plug and play, greatly improving the system flexibility. The USB codec is compatible with both Windows and Linux system. In addition, there is built-in DSP in the USB codec module. Customers can control the system and adjust the parameters, such as gain, frequency, EQ, delay and so on by PC UI.
