12AU7 Tube CSR8675 HIFI Bluetooth 5.0 ES9018 DAC Decoder for Car Fiber coaxial input support 24bit 196Khz for 8-300ohm

12AU7 Tube CSR8675 HIFI Bluetooth 5.0 ES9018 DAC Decoder for Car Fiber coaxial input support 24bit 196Khz for 8-300ohm

Description:

- This tube Bluetooth decoder adopted CSR8675 Bluetooth 5.0 solution plus ES9018 DAC hardware decoding, and tube 12AU7 as buffer output, specifically for smart phones, tablets to listen to HIFI level music.

- After the smart phone or tablet is connected to the Bluetooth module of the decoder via Bluetooth, audio source signal is transmitted to CSR8675 Bluetooth module of the decoder through Bluetooth lossless transmission, converted to I2S signal and transmitted to the ES9018 chip for hardware decoding and outputting the analog audio signal, after double op amp filtering. Finally, the signal outputted from12AU7 tube buffering, this will output a thick tube flavor, warm tone music.

- The entire transmission process is processed with a high level of signal, a true HIFI Bluetooth audio receiver. Make your smart phone and tablet is able to compare to the sound quality of CD player.

- Meanwhile, the decoder supports coaxial signals and optical fiber signals. The digital signal input of the Bluetooth is controlled by MCU software. The advantage of soft control volume is different from traditional impedance potentiometer, this is, the balance of left and right channels is higher, and the impedance of the traditional potentiometer also has physical errors, and for the channel separation, soft control is also much better than the impedance potentiometer.

Features:

1.    Use CSR8675 Bluetooth 5.0 solution plus ES9018DAC hardware decoding.

2.    Tube 12AU7 as buffer output.

3.    Supports input coaxial signal and optical fiber signal.

4.    All-aluminum casing, matte oxidation treatment, solid aluminum knob.

5.    Built-in tube designing inside,  not only is aesthetic appearance, but also better protects the fragile electron tube from being damaged by external forces.

6.    Perspective window design, the perspective window glass uses a 5x lens, through which the internal tube can be viewed.

7.    Volume ring indicator is designed to display the current volume position visually with the indicator light corresponding to the adjustment indicator of the volume knob. There is a white area and a red area, when the red area indicator lights up, it means the current volume is already relatively high.
