This Wondom KAB9 AA-KA32473 module is a very versatile amplifier, which can be used in a wide range of applications. It has four amplifier chips and is capable of delivering a power of 8x50W. Each chip can be used in PBTL 1x100W mode. Therefore, the AA-KA32473 can be configured to design a 7.1 audio system with 8x50W, a 6.1/5.1 system with 6x50W + 1x100W, a 4.2 system with 2x100W, and so on. A single module can be configured for multiple applications, which greatly enhances its flexibility. The selection of the operating mode is done simply by means of switches on the module.

The AA-KA32473 is also versatile in terms of its inputs. Moreover, a USB 7.1 codec is proposed by Wondom to limit the background noise and ensure a high quality audio reproduction.
