JAB4 & TAS5754 / TAS5756 for 4.2 System with 3-Way Digital Crossover, Bluetooth, I2S & ADAU1701 DSP

JAB4 is a 4CH 30W audio amplifier board integrated with high performance Bluetooth V5.0 module and ADAU1701 DSP. In addition to speaker output, JAB4 provides an I2S signal output, which can be transmitted to an I2S amplifier to build audio 4.2 system. Thanks to the equipped ADAU1701 DSP, we can write programs in SigmaStudio to our requirements.
In this video, we connect JAB4 and AA-AB32256 (2CH 30W I2S input audio amplifier board) through I2S input and output to get an audio 4.2 system. We also write a 3-way digital crossover program in SigmaStudio, through which, full range signal would be divided into 3 frequency bands according to the preset cut-off frequency, so as to achieve separate high, medium and low frequency audio playback. To let you have an instinct understand of how the program works, we have made demonstrations on playing each frequency band independently and add audio signal layer by layer to see the effects. Hope you can enjoy this video!
