AKM AK4493EQ DAC The DC01 is equipped with an AK4493 digital-to-analog conversion chip normally used in high-end sedentary DACs and integrating AKM Velvet Sound™ technology. The signal-to-noise ratio of this chip has been significantly improved compared to the previous model, the AK4490, which allows the DC01 to support high sampling rates up to 32bit 384kHz in PCM and up to native DSD256, while providing a THD+N of less than 0.001%. A design that will allow you to enjoy your music to the fullest, whether for use at home or on the move. Balanced headphone amplifier iBasso imports the concept of balanced amplification, normally reserved for high-end audio equipment, into this portable DAC adapter. The DC01 uses a fully balanced circuit with ultra-low distortion dual LDO to create a balanced amplifier, providing high output power while improving dynamics and overall reproduction quality. High-end cable In order to ensure optimal signal conductivity for excellent audio reproduction but also very good durability, iBasso carried out numerous tests before selecting this cable made of 8 braided wires. From smartphone to computer : USB UAC2.0 Soundcard The DC01 is equipped with a USB-C connector and uses the USB UAC2.0 reception standard. It is compatible with the vast majority of Android smartphones and tablets on the market. It is also able to connect to a computer under Mac OS or Windows using the supplied USB-C to USB-A high quality adapter. This allows it to work exactly like a sound card, and in an extremely simple way since the system is Plug & Play. Volume control app Windows 10 and Android 5.0 (or higher) support the UAC2.0 protocol by default. However, for compatibility reasons, Android smartphone manufacturers still use the SRC protocol on the audio output. When the DC01 is connected, the volume is set to the maximum by default and the device's software algorithm is used to reduce the volume.
