APRAŠYMAS
IBASSO DC02
USB DAC-C Hi-Res AK4490 32bit 384kHz DSD256 / headphone amplifier
The DC02 home iBasso is for audiophiles who want to use a new generation smartphone (without hardware analog output) as a high fidelity audio source compact & portable. With its exceptional weight of 8 grams and its advantageous dimensions, it will be the ideal partner for lovers of high quality music on the move.
The idea is to go through an external decoding circuit with respect to the phone to permanently circumvent problems related to gradual withdrawal of DAC chips. This approach will also be very relevant with previous smartphones with a rudimentary and inadequate DAC circuit to a high-resolution listening.
AKM AK4490
The interface DC02 operates for this purpose a chip DAC AKM AK4490EQ 32bit capable of decoding up to 384kHz audio stream (PCM) and DSD256 natively. It embeds technology Velvet Sound able to reconstruct with surprising clarity audio signals – including low – while offering a natural reproduction through a high bandwidth.
This component is known for its first class audio performance and meets regularly with the devices known High Fidelity.
headphone amplifier
In additional AKM AK4490 chip, the DC02 home iBasso includes a second chip headphone amplifier.
The latter can 32Ω driver loads up with an output level of 900mV. Is a sufficient reserve of power essentially helmets built for mobile use and semi-nomadic.
The DAC circuit and the headphone amplifier circuit to reach an extremely low THD of 0.001% (measured at full load 32Ω 0.9Vrms)
Compatible PC
Far from being limited to only smartphones and tablets, the DC02 also works as a decoder for turning computers on a Windows operating system, Linux or Mac.
It comes to this effect with its USB-C female adapter to USB A male to offer fast connectivity solution with multiple types of sources.
The interface will be able to perform a function of DAC / amplifier nomadic helmet company smartphone, then join a desktop computer to enjoy an audio playback quality throughout the day.
Quality wires
For flexibility and to avoid avoidable mechanical stresses on all of the connectors, the male USB connector is located at the end of a 80mm quad wire cable with flexible sheath.
This ensures excellent signal transmission while absorbing shocks and pressures applied on the most sensitive parts of your smartphone.
Operating principle
Whether it’s a computer, a smartphone, tablet or SBC, the DC02 overrides the internal hardware of the machine (if any) to entrust the decoding and amplification to higher quality components than those found regular motherboard / chipset.
This results in a significant gain in the audio clarity (decrease of noise and distortion, improve of linearity in frequency response, better channel separation … etc).
