Description

This board is a high performance 1 x 100W audio amplifier board with ADAU1701 DSP integrated, which can be used with WONDOM JAB2 to build audio 2.1 system with both DSP and Bluetooth. This JAB3-160 is suitable for boomcase, DIY, digital crossover and other applications. With WONDOM ICP series, it can be programmed via SigmaStuido. Customers can control the audio system through the four potentiometers on the JAB3-160 or through WONDOM APP - Miumax. It supports WONDOM battery board, greatly improving the flexibility.
