iBasso DC04 Headphone Amplifier DAC Type-C To 4.4MM Phone HiFi Headphone External Sound Card Black

iBasso DC04 Headphone Amplifier DAC Type-C To 4.4MM Phone HiFi Headphone External Sound Card Black

Features:
- 4.4mm mobile phone headphone amplifier DAC.
- Balanced DAC headphone amp cable. DC04 uses two high-performance HiFi decoding chips CS43131 to build a 4-channel DAC true balanced output line, which can significantly improve resolution and channel separation, and present rich sound details.
- CS43131 has great potential, and its sound is sweet and friendly to listeners' ears. The DC04 dual DAC design ensures the high-quality sound of the second-generation balanced decoding amp line.
- Dual CS43131 decoding chips; SNR 133dB; balanced driving force 195mW at 32Ω, 4Vrms at 300Ω; noise level ≤0.9pV, clean and transparent sound; THD+N<0.00032% (-110dB); output impedance 0.12Ω (The above parameters are AP measured indicators).
- Two CS43131; PCM32/384; DSD256; THD+N<-110dB; Hi·Res Audio.
- Support mobile phone to play online music.
- 4.4mm balanced interface: Japanese high-quality balanced interface with excellent sound effects, reliable stability and longer service life.
- Metal shell adopts a wire drawing process, texture is delicate, the touch is charming, and the high-end HiFi player is generally exquisite. Selective 4 strands of spiral-wound copper silver-plated wire for excellent sound.
- Adopt type-C interface and standard UAC2.0 sound card chip. It is not only for most Android phones and tablets on the market, but also can enables connection for Apple/Windows computers through an USB-C to USB-A adapter to easily realize external decoding. Plug and play.
- UAC volume. Provides exclusive APK software to achieve 64-level hardware volume adjustment. Mobile phones usually use software algorithms to adjust volume, usually only about 10 levels. The volume of each level varies greatly, making it difficult to provide fine adjustment. The output level of DC04 is as high as 4Vrms, even if the volume of your mobile phone is only 1, there may be a loud volume phenomenon. To this end, we have written an APK that supports UAC2.0 volume adjustment to achieve 64-level hardware volume adjustment. Each level of the phone volume can be subdivided into 64 levels. The volume can be precisely controlled.

Operation Introduction:
DC04 is suitable for devices for systems above Android 5.1, plug and play (affected by the device system or hardware, there may be compatibility differences on a very small number of devices for Android). However, because DC04 output level is as high as 4Vrms, even if the volume is 1 on some devices for Android, the volume may be loud. Therefore, it is recommended to install exclusive APK-iBasso UAC for finer volume adjustment. For some models of devices for Android, you may need to manually turn on OTG function in system settings. When used with mobile phones, it supports up to PCM32bit/384kHz and Native DSD 256 output.
