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.

Subwoofer amplifiers

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.

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.

KAB series is a highly cost-effective amplifier board series specially designed for self-service equipment and game machine applications, such as vending machine, ATM, service robot, arcade machine, amusement equipment and so on.

Recently, Sure Electronics released KAB9, an 8CH audio amplifier board, providing 50W / 100W output power per channel, fully meeting the requirements of medium and large scale game machines and amusement equipment on power.

Suitable for audio 4.0/5.1/7.1 system

KAB9 supports PBTL configuration, which means every two channels can be modified to mono channel with double power, making it suitable for common used audio 4.0 / 5.1 / 7.1 systems in game machine applications. For example, KAB9 – 850 can be configured as 4 x 100W, 6 x 50W +1 x 100W or 8 x 50W. One product, multiple configurations for different applications, which is highly cost-effective.

Sure Electronics provides switch for switching between BTL mode and PBTL mode, which is very swift and convenient.

Supporting 8CH USB codec

Taking the ground noise caused by single-ended input, Sure Electronics has developed an 8CH USB codec for KAB9. 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.

Four stages gain adjustable

There are four stages gain on KAB9 for customers’ choice according to their system needs. DIP switches are provided on board for adjustment.

If you are interested in KAB9, please contact us with info@sure-electronics.com.

KAB series is a highly cost-effective amplifier board series specially designed for self-service equipment and game machine applications, such as vending machine, ATM, service robot, arcade machine, amusement equipment and so on.

Recently, Sure Electronics released KAB0, a pure digital stereo I2S amplifier, delivering 5W per channel, suitable for self-service equipment and small-scale game machine.

Sound enhancement algorithm

Integrated with sound enhancement algorithm, KAB0 can output extremely high volume in spite of its small size and greatly improve the SPL of small speakers.

USB codec input

KAB0 supports USB codec input, which avoids ground noise and ensures high sound quality. In addition, KAB0 supports I2S input and Microphone input. Customers can choose to their requirements.

Equipped with record function

Thanks to the integrated USB codec, KAB0 supports record function.

Integrated with DSP

KAB0 is integrated with DSP, supporting 10bands EQ adjustment and parameters control. With the connection of WONDOM programming board, KBA0 supports PC UI control.

Supporting USB Type-C power

KBA0 supports powered by USB Type-C, which means KAB0 can be powered up when customers use USB cable to input signal and no extra power supply is needed.
