ZK-QCC Qualcomm QCC5125 QCC3034 Bluetooth 5.1 Lossless Decoding Board APTX LDAC Audiophile Grade DC8-32V PCM5102A DAC Chip

Product Features:

1. On-board antenna provides an open-air transmission range of approximately 50 metres without requiring an external antenna. Should installation within a metal enclosure necessitate signal shielding, an external antenna may be purchased and fitted to the reserved IPEX antenna socket.

2. Features an I2S output interface for connecting to amplifiers with I2S input capability. Includes a button expansion interface enabling track navigation (previous/next), play/pause, and volume control, offering strong expandability.

3. Features a USB Type-C port for PC sound card connectivity or USB power supply. For the QCC5125 model, USB enables connection to official software for EQ adjustments within the internal DSP – intended solely for experienced enthusiasts with software expertise.

4. Includes complimentary acrylic enclosure and magnetic mounting columns for quick, convenient magnetic attachment.

5. QCC5125/QCC3034 + PCM5102A delivers lossless transmission and decoding with zero data loss, perfectly reproducing every dynamic nuance and detail. High frequencies are crisp without harshness, midrange is smooth and rounded, while bass is powerful with excellent elasticity. Exceptional specifications: 112dB dynamic range, 112dB signal-to-noise ratio, -93dB total harmonic distortion. The comparison speaks for itself.

6. Critical components utilise audiophile-grade capacitors, excelling in dissipation factor, leakage current, ripple current, and ESR. These enhance sound velocity, dynamics, texture, and density, elevating overall performance across treble, midrange, and bass frequencies. Variations in temperature, voltage, and frequency impact audio quality; superior dissipation factor minimises such effects. Low leakage current reduces ageing and extends lifespan while lowering noise; minimal ESR decreases high-frequency impedance and accelerates dynamic response.
