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. Versatile Application 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. Convenient Buttons: SOURCE: Toggle between Bluetooth, S/PDIF digital, or line-in modes. Long press the SOURCE button or use FUN1 key on the remote to access the filter selection menu. You can cycle through filter options, which include Fast Roll-Off, Slow Roll-Off, and Minimum Phase. Play/Pause/Long: press to disconnect Bluetooth. Previous Track/Next Track Aluminum Volume Knob: Adjusts headphone output volume with precision. Cayin provides a complimentary remote control with the BTC-2. It supports infrared remote functionality allowing convenient adjustment of various settings with ease. The high-gain "rubber ducky" antenna can be quickly detached when not using Bluetooth saving space if things are tight. 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.
