Excellent Performance In All Aspects
The DCO4PRO 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.
With a 100 step hardware volume control, the DC04 Pro offers fine volume adjustment, particularly compared to the default 16 step volume control for iPhone users.
The strength of the DCO4PRO is a full sound that is musically rewarding and easy to use.
Ultra Low Noise Output - Noise Floor at the Nanovolt Level
The Cirrus Logic flagship DAC CS43131 with Master HiFiT™ technology provides outstanding performance and excellent sound. With the ultra-low noise LDO that has a 100dB Power Supply Rejection Ratio, power purity for the DAC chips is assured. The end result is amazing sound quality with a superb black background for the DC04Pro.
Dual RT6863 OPAMP - 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@320.
With the well-designed analog circuit, the DC04PRO renders your sound full bodied with emotional impact. You can say goodbye to the often thin and cold digital sound of smartphones.
Superb Measured Performance
Measurements are not the only standard to verify the quality of sound, but they are enough to tell the quality of product materials and the implementation of the product design. The DC04PRO once again raises the ceiling of AP measurements.
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.
Upgraded UAC Companion APP
The iBasso UAC app fully suports the DC04Pro, offering control over the 100 step hardware volume, 5 digital filter options, 3 options for gain control, 2 options for output mode, a 20 step L/R channel balance adjustment and an on/off toggle for power saver mode.
