This is Bluetooth Headphone amplifier.Bluetooth receiving audio signal I2S output and ES9023 dac chip can greatly improve the Bluetooth audio effect, high signal-to-noise ratio, low distortion,

3.5mm headphone amplifier interface is compatible with ordinary 3.5mm headset.Components uses JRC4556 high power output chip and buffer headphone amp circuit. Headphone Power Output: 30mW@16R, 50mW@32R, 70mW@68R, 70mW@150R.


Using op chip is OPA 1656IDR and ESS9023 JRC4556.MCU intelligent control, soft switch for better switch input channel. Independent power supply design with shielded function effectively reduces interference. Relay is used to switch signal, better than normal switches. Also adopts black immersion PCB board and BC coupling capacitance


Uses GE5654 vacuum tube with tube buffer circuit which has dynamic and sweet sound quality.

Bass/Treble/Volume Control: It has independent bass, treble and volume control knobs, which helps you set sound effect easily according to your preference. Long press Select button to power on/off, and short press to switch signal input
