      Product Details

      Sure Electronics AA-KA32473 8 x 50w 6.1, 4.2, 4.0 configurable usb codec input Amplifier module


      As an audio amplifier specially designed for game machine applications on the basis of standard products platform, WONDOM KAB9 inherits Sure Electronics consistent high reliability and high cost-performance. Fully taking customers’ requirements into consideration, we employ four AMP chip on KAB9 as 8 x 50W, all of which supports separate configuration into PBTL mode – 1 x 100W. That means KAB9 can be set as 8 x 50W for 7.1 audio system, 6 x 50W + 1 x 100W for 6.1/5.1 system, 4 x 50W + 2 x 100W for 4.2 system, 4 x 100W for 4.0 system and so on. Only one board can be configured for several applications, greatly improving system flexibility. The switching is conveniently achieved by the switches on the board, without any need of complex soldering. KAB9 is capable of delivering a peak output power of 8x 100W if it is equipped with a fan. KAB9 supports differential input. In addition, KAB9 can support multiple input methods through connecting with an external plug-and-play module as a daughter board. We have released a 7.1 USB codec module for joint use with KAB9, which can avoid ground noise and ensure high quality audio playback. In future, we will develop various input module to add more functions and possibilities for the KAB9.

      8CH 50W, suitable for 8.0/7.1/5.1/4.2/4.0 audio system

      KAB9 is an 8-channel audio amplifier board, delivering 50W / 100W per channel. High output power and multichannel make JAB9 perfectly applicable to large-scale game machines, arcade equipment, race simulators and other industrial applications. KAB9 supports PBTL configuration, which means that KAB9 can work as various output mode, like 8.0 mode (8x50W) for audio 8.0/7.1/6.2 system, 6.1 mode (6x50W+1x100W) for 6.0/5.1 system, 4.2 mode (4x50W+2x100W) for 4.2 system and 4.0 mode (4x100W) for 4.0 system.

      8CH USB Codec Input

      KAB9 can support multiple input methods through connecting with input modules as daughter board, which greatly improves system flexibility and expandability. We have released a 7.1 USB codec input module for joint use with KAB9, which is compatible with both Windows and Linux system. There is no need to worry about ground noise because of the USB digital input. If you need analog input, differential input or other input methods, please feel free to contact us for further discussion.
