Using TPA3116 as the core chip, TPA3116 is a Class D power amplifier IC from TI, which can achieve modulation frequency up to 1.2MHZ, high power output distortion less than 0.1% (10W), and up to 50W+50W dual channel output.
Using the classic 6J1 tube, during the design process, the line is optimized several times to make it extremely daring, the sound is warm and sound-resistant, the sound field is wide, the unique high and low sound adjustment and wireless Bluetooth function.
The Bluetooth module is a BTM625 Bluetooth audio module, which uses CSRA64215 chip, supports A2DP, AVRCP, HFP, TWS, AAC, I2S, APTX, APTX-LL, etc., adopts 4M SPI FLASH memory chip.
The Bluetooth decoding part uses the latest US ESS9023 top-level decoding core. The ES9023 is a 24-bit stereo audio digital-to-analog converter (DAC) from ESS. It uses the industry-leading SABRE digital-to-analog conversion technology and has a dynamic range of 112dB.
