AB1520H_V0.1 AB1520H Product Brief Stereo Speaker/Headphone/Sound bar with wireless subwoofer Solution For DSP Intensive Audio Applications Product Overview AB1520H is an advanced single-chip solution which integrates baseband and radio for Stereo headset and speaker applications. It is Bluetooth 4.2 certified and supports wide band speech which is defined at HFP1.6, AAC decoder, and 2-Mic for better noise reduction and echo cancellation performance. AB1520H embeds serial flash which is more flexible for customer SW upgrading and 3rd party SW porting is supported. With optimized MCU structure, interface arrangement and better DSP algorithm, AB1520H provides higher performance and crystal voice and music quality in most of the Bluetooth audio application such as Headphone, Speaker and Sound bar systems. AB1520H supports “AiroStereo” which two speakers can connect to each other, play left channel in one speaker and play right channel in another speaker as a wireless stereo system. “AiroStereo” can let end users have great stereo experience without wire connection. AB1520H also supports “AiroShare” which can relay the music from one audio device to another device wirelessly that users can easily share the music with their friends or family from the same audio source. AB1520H supports “AiroWoofer” which can play stereo in the sound bar and send the bass signal to subwoofer with very low latency. It means customers can quickly and easily develop high-quality sound bar with wireless subwoofer as 2.1 channel products.
