Cayin BTC-2 Bluetooth Receiver, DAC & Headphone Amplifier

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-powered DAC ensures precise audio 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.

Bluetooth Connectivity
Received and decoded by the device to drive headphones or output LINE analog and S/PDIF digital signals.

S/PDIF Digital Input
Received and decoded by the device to drive headphones or output LINE analog signals.

Line In
Received by the device to drive headphones or output LINE analog signals. When using LINE IN, the signal bypasses the internal DAC and is routed directly to the amplification circuit.

Uncompromising Components for Reliable Sound
Equipped with Nichicon coupling capacitors imported from Japan, the circuit ensures exceptional clarity and transparency of sound while minimizing distortion and noise.

The audio circuit utilizes a high-precision, high-performance audiophile-grade operational amplifier (op-amp), delivering outstanding current drive capability, excellent transient response, and low noise floor, all of which guarantee high-precision audio signal processing.

The volume knob features a premium, precise ALPS potentiometer from Japan, providing a superior tactile feel with low distortion and noise, ensuring precise volume adjustment.

User-Friendly Design
The BTC-2 features a USB-C power port which makes things easy. The included power cable is widely compatible, allowing for easy connection to various power adapters and even directly to power banks maximizing BTC-2's flexibility.

Sleek Design
The panel is crafted from 6mm thick, high-quality Aluminum Alloy with refined, brushed anodized finish. The BTC-2 is equipped with an OLED dot matrix display, providing clear and intuitive playback info at a glance. The sleek and minimalistic designed chassis seamlessly fits into various environments, making it a stylish and versatile addition to any setup.
