iBasso DC04 PRO
Flagship dual DACs
The KA5 features dual Cirrus Logic CS43198 DACs, known for their efficiency and their ability to sound good with a wide variety of music, to give you a serious upgrade to your sound.
Well Selected Parts and Advanced Technologies
The DC04PRO combines many well selected parts and advanced technologies, such as dual CS43131 flagship DACs, dual RT6863 high current output OPAMPs, synchronous DC-DC converter, ultra-low noise LDO, FPGA, KDS femtosecond oscillator, multi-functional APP, Pentaconn 4.4mm balanced socket, CNC aluminum case, and tempered glass panels. All of these forged into a USB DAC & AMP with excellent sound quality, high output power, high current output, dual output interfaces, interchangeable cables, excellent power consumption control, and outstanding specs. The strength of the DCO4PRO is a full sound that is musically rewarding and its ease of use.
The Cirrus Logic flagship DAC CS43131 with Master HiFiT™technology provides outstanding performance and excellent sound. With the ultra-low noise L.DO that has a 100dB Power Supply Rejection Ratio to ensure the power purity for the DAC chips, results in an amazing sound quality with a superb black background for the DC04Pro.
Svnchronous DC-DC Converter & Ultra-low Noise LDO
The quality of the power supply directly affects the sound quality in no small way. DC04PRO utilizes a synchronous DC-DC converter and low-noise high-speed LDO, ensuring sufficient high purity power for the dongle, bringing a dynamic and powerful sound to your music.
Balanced AMP 10V Voltage Swing
DCO4PRO utilizes dual RT6863 chips, creating a 4-way fully balanced amp featuring ultra-low distortion. With an output current of up to 100mA and working at a 10V voltage swing, the DCO4PRO output reaches 280mW@32ΩWith the well-designed analog circuit, the DCO4PRO renders your sound full bodied with emotional impact. You can say goodbye to the often thin and cold digital sound of smartphones.
FPGA + KDS Femtosecond Oscillator
We have used our in-house developed FPGA algorithm and for the first time it is used in a dongle. Together with the KDS femtosecond oscillator, jitter is well controlled, and sound reproduction becomes more distortion free, enhancing the sound quality.
Lower Power Consumption
DCO4PRO consumes less power and provides a power saving mode option. When using normal mode balanced output, the power consumption is 650mW; the single ended output will turn off the unused half of the AMP, lowering the power consumption to only 550mW. When the power saving mode is on, it turns off and bypasses the AMP section, with output directly from the DAC's internal AMP. In this mode, the power consumption is as low as 410mW Compared with the power consumption of similar dongles, which can be as high as 700 to 800mW, the power consumption and heat generation of DCO4PRO are lower, enhancing long-term listening.
New Companion APP
App with practical features is in place, iBasso UAC APP has been fully upgraded to work with the DCO4PRO.
Exquisite and Practical Appearance Design
The DCO4PRO case is made using CNC to precisely manufacture the high-grade aluminum alloy. The open volume control structure requires complex steps during machining, which is both visually appealing and fits with required function. Using tempered glass panels, the DCO4PRO is both esthetically appealing while conveying the quality of build. Grey and Blue colors are available to meet individual preferences.
Standard for the DC04PRO is a detachable cable design with a USB-C to USB-C cable with a USB A adapter, allowing it to be used with most Android devices. When using a USB-C to lightning cable (bought separately) with the DCO4PRO, you can use it with APPLE devices. *The CB18 and USB-C to lightning cable and needs to be purchased separately.
