■Uses two Sabre ES9218P DAC chips, which are very power efficient while providing high resolution and clear, powerful output.
■Supports balanced connection. Connect your favorite earphones or headphones to the 2.5mm balanced output jack to make the most of the potential of the two ES9218P.
■You can easily switch between two gain settings (three, including Dual DAC mode when using single-ended output) and four digital filter settings that change the sound quality with a single ""mode button"" on the top of the main unit.
■Even when using 3.5mm single-ended output, you can drive both ES9028P by selecting Dual DAC mode. This allows UP4 to meet the expectations of users who pursue high sound quality and high output, not just balanced output.
■The CSR8675 Bluetooth chip ensures stable connection over long distances, minimal latency, and excellent resistance to external interference.
■The high-quality Knowles SiSonic microphone and the new 8th generation cVc noise cancellation technology keep the voice during calls clean even in noisy places, allowing you to talk with clear voice.
■The UP4 supports NFC pairing and can be easily paired with NFC-enabled devices in just a few seconds.
*NFC pairing requires that the connected device is compatible.
■Shanling UP4 can be connected to your computer and used as a USB-DAC/AMP. No additional drivers are required, just connect with a USC Type-C cable and you're ready to go.
■UP4 has been certified by the Japan Audio Association as both ""Hi-Res Audio"" and ""Hi-Res Audio Wireless"".
