Qualcomm isolated, lossless, audiophile-quality Bluetooth 5.0 decoder preamplifier-receiver board, compatible with APTX and simple SBC.WHBYV

1. With exquisite shell, the shell can well shield the external magnetic field interference and reduce the background noise. 2. External 2.4G Bluetooth antenna, the transmission distance is more than 30 meters. 3. The internal isolation power supply eliminates the interference problem between the decoder board and the power supply, amplifier, and audio cable, without background noise and current sound, improving the sound quality and reducing the troubles of customers. 4. TYPE-C USB interface can realize PC sound card connection or USB power supply. 5. QCC3034+PCM5102A, lossless transmission, lossless decoding, no loss, perfectly showing the dynamics and details of the sound, high frequency without burrs, mid-range round, low frequency powerful, good elasticity. Extremely high parameter percompatiblemance: dynamic 112dB, signal-to-noise ratio 112dB, distortion -93dB. 6. Fever capacitors are used in key parts, which percompatiblem well in parameters such as dissipation factor, leakage current, ripple current, ESR, etc., improve the speed, dynamics, texture, and density parameters of the sound, and improve the overall quality of the high, medium and low frequencies. Different temperatures, voltages, and frequencies will affect the sound quality, and a good dissipation factor can reduce the impact. The small leakage current of the capacitor reduces the degree of aging and prolongs the life, reduces noise, and the low ESR reduces high-frequency impedance and increases the dynamic response speed. 7. With Bluetooth unpairing button, press and hold compatible 3 seconds to cancel the Bluetooth connection, and press and hold compatible a short time to pause the music.
