Cayin BTC-2

Seamless Connectivity
The BTC-2 features the Qualcomm QCC5125 High-Fidelity Bluetooth SoC with Bluetooth 5.1. It supports a variety of high-resolution wireless audio codecs, including aptx HD and LDAC (LDAC transmits up to 96kHz/24Bit high-resolution audio). Enjoy wireless convenience with stable signal transfer and exceptional sound quality for a smart, user-friendly experience.

Using Bluetooth does not mean Cayin compromises on circuit design. The BTC-2 features a dual-chip, 4-channel balanced circuit with positive and negative signal separation, this circuit design maintains balance throughout the decoding and amplification stages. Thanks to the balanced circuit, it significantly reduces noise and distortion, delivering clearer, more accurate sound. Every subtle moment of signal transmission and conversion faithfully preserves the original audio, free from unwanted distortion and interference.

Precise and Pure
Equipped with the ES9018K2M DAC chip, specially designed for stereo systems, this low-power DAC ensures precise reproduction and pristine audio performance. Whether you're connecting to a TV, set-top box, or smartphone via S/PDIF input or Bluetooth, you'll enjoy a more true-to-life and detailed sound experience.

Superior EMI Shielding
The body is crafted from a finely engineered all-metal chassis, expertly designed to mitigate the impact of external electromagnetic fields on the device's circuits and components. This design provides effective EMI shielding, ensuring high-fidelity audio signal transmission.
