Product Features
- Dual ES9219C DAC: The UP4 2022 is equipped with two deeply developed ES9219C chips as the core DAC. The heat generation is stably controlled while the power consumption is low. The resolution and restoration power are convincing, and the strong output power presents excellent warm sound quality.
- 2.5mm Balanced + 3.5mm Single-ended Output: The UP4 2022 is equipped with a 2.5 + 3.5mm dual interface. In the balanced output mode, the dual ES9219C DAC burst out synchronously, and the left and right separation, sound field performance, and signal output are getting better and better.
- Long battery life: UP4 2022 is equipped with a large 540mAh battery, charging for 2 hours, listening for a whole day about 300 hours long standby, single ended is 11.5H, balance is 9.5H, guarding your HiFi journey.
- More function: HD calling; High-gain, low-gain, dual DAC booster switch freely; NFC function; APP Control; UP4 2022 is equipped with mainstream Type-C USB interface, supports USB DAC, mobile phone, computer, tablet, TV, car audio and other equipment, easy to connect.
- Bluetooth 5.0 Headphone Amplifier: Qualcomm CSR8675 Bluetooth chip, UP4 2022 adopts Bluetooth 5.0 version, supports LDAC / LHDC/ aptX HD / aptXLL / aptX / AAC / SBC full-format Bluetooth encoding protocol, provides stable and smooth Bluetooth transmission, and bid farewell to delay. The corresponding lights are different under different protocols, and you can enjoy a free and intelligent experience.
Product Description
Single ended output - Output Power: 1.75V / 32 Ohm (100mW / 32 Ohm) (Dual DAC Mode) 1.51V / 32 Ohm (71mW / 32 Ohm) (High Gain Mode) - Frequency Response: 20Hz -40kHz (-0.7dB) - THD+N: 0.002% (A - W /1V / 32 Ohm) - Channel Separation: 71dB / 32 Ohm - Signal-to-noise ratio:119dB - Noise Floor: 114dB (High Gain Mode) - Output Impedance: <1 Ohm Balanced output - Output Power: 2.3V/32 Ohm(165mW / 32Ohm) - Frequency Response: 20Hz -40kHz(-0.7dB) - THD+N: 0.0018% (A-W / 1V /32 Ohm) - Channel Separation: 92dB / 32 Ohm - Signal-to-noise ratio: 119dB - Noise Floor: 119dB - Output Impedance:<1 Ohm - The UP4 22 version adopts the ES9219C as the DAC. The signal-to-noise ratio is as high as 130db, and the dynamic range is as high as 121db; Support PCM384kHz / 32bit, DSD 256. Note: When used as a USB DAC, only PCM 48kHz is supported. - CSR8675 high-definition Bluetooth chip, Qualcomm's new generation Bluetooth chip, supports Bluetooth 5.0 high-definition format, has more stable transmission, stronger signal, lower latency, and supports multiple Bluetooth transmission protocols; Supports Bluetooth protocols: LDAC, LHDC, aptX HD, aptX LL, aptX, AAC, SBC. - The UP4 22 version comes with an OLED display light, which changes the light in real-time when under different Bluetooth connection protocols, allowing for a free and intelligent experience. - Supports 3.5 single ended output and 2.5 balanced output, eliminating mainstream headphones on the market and no longer worrying about compatibility. UP4 version 22 output power increased to: single ended 100mW@ 32 Ohm / balance 165mW@ 32 Ohm and has lower distortion. - The UP4 22 version inherits the unique feature of the Shanling family: single/dual DAC switching. When working with a single DAC, the power consumption is lower and the range is longer; When working with dual DACs, the quality is higher.
