QCC3034 Bluetooth Lossless Decoder Board APTX Amplifier Wireless Receiver

1. On-board antenna, open transmission distance of about 50 meters, without external antenna. If installed into the metal shell to avoid signal shielding, you can buy your own external antenna installation, reserved IPEX antenna seat2. 12S output interface, can be connected with 12S input function of the amplifier, leave the key expansion interface, to realize the up/down song switch, pause/play, volume adjustment, scalability is strong3. There is a TYPE-C USB interface, which can realize PC sound card connection or USB power supply; for QCC5125 models, through the USB can be connected to the official software on the internal DSP in the EQ operation, only for users who have a software foundation4. With acrylic shell and fixed magnetic column, magnetic adsorption fixed installation, convenient and fast5. QCC5125/QCC3034+PCM5102A, lossless transmission, lossless decoding, no loss, to show the sound of each dynamic and details, high-frequency burr, rounded midrange, low-frequency power, good elasticity6. Extremely high parameter performance: dynamic 112dB, signal-to-noise ratio 112dB, distortion -93dB7. Key parts of the use of fever capacitors, in the fugitive factor, leakage current, ripple current, ESR and other parameters of excellent performance, improve the speed of sound, dynamics, texture, density parameters, the overall quality of the high school and low three-frequency upgrade8. Different temperatures, voltages and frequencies will affect the sound quality, and a good fugitive factor can reduce the impact9. Capacitor small leakage current to reduce the degree of aging to extend the life, reduce noise, low ESR to reduce high-frequency reactance, increase the dynamic response speed10.
