Features:
- Fine sound, dynamic balance
- QCC5125 Bluetooth 5.0 lossless solution, supports for LDAC, aptX-HD, AAC and other encoding formats. Support 24bit 96kHz audio CD-level sound quality, super cost-effective
- Good sound quality, no delay, no lag. Reduce the secondary loss of sound quality compression, accurately reproduce full audio broadband, HIFI level high fidelity
- PCM1794A chip boasts a high sampling rate and resolution, and a sense of speed and transparency. The low-frequency, mid-frequency and high-frequency sounds are very commendable, and the human voice is round and sweet. It is a very cost-effective chip
- CT7302 receiver solution. PCM 32BIT/384KHZ allows PCM1794A to support DSD and DOP input. CT7302 is a lower S/PDIF receiver than AK4118 jitter
- High sampling rate. Advanced digital input processing chip CT7302, input channel with power-down memory function, low jitter, high sampling rate
- Using MCU program, soft control optimizes the performance of PCM1794A. Turn on and off via the panel keys. Automatically recognize the input signal. Breaking sound elimination technology: Song switching and fast forwarding, sampling rate changes, etc., will produce broken sound, which is solved by soft control
- Using active LPF, and I/V conversion design. Compared with other passive RC structures, it is more conducive to improving the system's response speed to audio, making signal distortion lower, and music dynamics more rapid and powerful
- 3pcs dual op amps: reserve IC sockets, and replace op amps with different music styles by simply plugging in and out, making it more playable
- High-quality power supply: Built-in positive-negative voltage conversion design, which is more conducive to improving the symmetry of positive and negative voltages than other capacitor voltage dividers, making Bluetooth signals for LDAC more stable and PCM1794A decoding smoother
- Secondary voltage stabilization: high-performance power purification circuit design, reducing ripple interference caused by switching power supplies, and providing clean power for DAC and LPF
- Suitable for multiple input and output devices
