BTC-2
Wireless Hi-Fi Without Compromise
The Cayin BTC-2 brings premium wireless audio performance to your desktop system, combining advanced Bluetooth technology, high-quality DAC conversion and a fully balanced analogue circuit design. Whether you're streaming music from a smartphone, connecting a television via S/PDIF, or using analogue sources, the BTC-2 delivers exceptional sound quality with remarkable versatility.
Bluetooth 5.1 with High-Resolution Audio Support
Powered by Qualcomm's QCC5125 Bluetooth audio platform, the BTC-2 provides fast, stable and reliable wireless connectivity with support for a wide range of high-quality codecs, including LDAC and aptX HD.
LDAC support enables wireless transmission of high-resolution audio up to 96kHz/24-bit, allowing listeners to enjoy exceptional detail, clarity and musicality without the need for physical cables.
Fully Balanced Audio Architecture
Cayin's engineering team has designed the BTC-2 around a fully balanced four-channel audio circuit that maintains balanced signal transmission throughout both the decoding and amplification stages.
By independently processing positive and negative signal paths, the BTC-2 significantly reduces noise, distortion and interference while improving channel separation and overall accuracy. The result is a cleaner, more transparent sound that remains faithful to the original recording.
ESS ES9018K2M DAC Performance
At the heart of the BTC-2 is the highly regarded ES9018K2M DAC from ESS Technology. Optimised for high-fidelity stereo applications, this DAC delivers detailed, dynamic and natural sound reproduction with excellent resolution across the entire frequency range.
Whether receiving audio via Bluetooth or through the S/PDIF digital input, the BTC-2 ensures every detail of your music is reproduced with precision and accuracy.
Versatile Connectivity for Modern Audio Systems
The BTC-2 is designed to serve as a flexible audio hub, supporting multiple source devices and output configurations.
Bluetooth Input
Receive and decode wireless audio from smartphones, tablets, computers and compatible streaming devices. Audio can be routed directly to headphones, line outputs or S/PDIF output.
S/PDIF Digital Input
Connect televisions, streamers, CD transports and other digital audio sources for high-quality DAC conversion and headphone listening.
Analogue Line Input
Connect external analogue sources directly to the amplification stage. When using Line In, the signal bypasses the internal DAC for a pure analogue signal path.
Premium Components Throughout
Every stage of the BTC-2 has been carefully engineered using high-quality components selected for their sonic performance and long-term reliability.
Japanese Nichicon capacitors help preserve signal purity while reducing distortion and unwanted noise. High-performance audiophile-grade operational amplifiers provide excellent current delivery, low noise and outstanding transient response, ensuring accurate and engaging sound reproduction.
Volume adjustment is handled by a premium ALPS analogue potentiometer, renowned for its smooth operation, precise channel balance and superior tactile feel.
Superior EMI Protection
The BTC-2's precision-engineered all-metal chassis provides excellent protection against electromagnetic interference, helping to preserve signal integrity and maintain consistent audio performance even in electrically noisy environments.
Convenient Everyday Operation
Designed with ease of use in mind, the BTC-2 features a USB-C power connection that offers flexible powering options. It can be used with standard USB power adapters or portable power banks, making it equally suitable for desktop and portable installations.
An included infrared remote control provides convenient access to key functions from across the room, including input selection, volume adjustment and display settings.
The detachable high-gain Bluetooth antenna can be removed when wireless connectivity is not required, helping to maintain a clean and uncluttered setup.
Elegant Design Meets Practical Functionality
The front panel is machined from 6mm-thick aluminium alloy and finished with a premium brushed anodised treatment, creating a refined and sophisticated appearance.
A custom OLED dot-matrix display provides clear visual feedback for source selection, codec information and playback status, while the compact chassis integrates effortlessly into a wide variety of desktop, headphone and Hi-Fi systems.
Combining advanced wireless technology, audiophile-grade components and exceptional build quality, the BTC-2 delivers a modern high-resolution listening experience without sacrificing the sound quality that music enthusiasts demand.
