Well selected and implemented parts result in excellent performance in all aspects

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.

Dual Cirrus Logic CS43131 ultra-low noise LDO ensure power purity

The Cirrus Logic flagship DAC CS43131 with Master HiFi™ technology provides outstanding performance and excellent sound. With the ultra-low noise LDO 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.

The DC04Pro noise floor is at Nano volt level.

Synchronous DC-DC converter & ultra-low noise LDO unprecedented power supply for a dongle

The quality of the power supply directly affects the sound quality in no small way. DCO4PRO 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.

RT6863 dual OPAMP x 2, a true balanced AMP 10V voltage swing

DC04PRO 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@32Q. 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.

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.

Once again, the ceiling of measurements have been raised

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 the AP measurements.

S/N: 131dB

THD+N: 0.00013%

280mW@32Ω

Noise floor: 0.9μV

The noise floor is Nano volt level, approaching ZERO.

Lower power consumption less burden to the master device

DC04PRO 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 DC04PRO are lower, enhancing long-term listening.

New companion APP with practical features is in place

iBasso UAC APP has been fully uograded to work with the DC04PRO.

Hardware: 100 steps

Digital filters: 5 options

Gain control: 3 options

Output mode: 2 options

L/R balancer: 20 steps

Power saver: on/off

CNC aluminum case with tempered glass panels

The DC04PRO 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 DC04PRO is both esthetically appealing while conveying the quality of build. Grey and Blue colors are available to meet individual preferences.

Detachable cable meeting a wide range of cables used

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 DC04PRO, you can use it with APPL E devices.

*The bottom cable in the picture is the CB18, it is not included in the package. The CB18 and USB-C to lightning cable needs to be purchased separately.

Operation Instructions

The DC04PRO is plug-and-play on Android Smartphones and tablets with Android 5.1 and above without installing drivers or third-party APPs (due to the Android device s system or hardware limitation, there may be a low compatibility issue with some smartphones or tablets). On some Android devices, it may be necessary to manually turn on the OTG function in the system settings.

The DC04PRO is plug-and-play on Mac and Win10 computers. For Win XP, Win 7, and Win 8 systems, please download the driver from our website www.iBasso.comunder Downloads. Once properly installed, the DC04PRO can be used as a USB sound card. iPhone's volume control is only 16 steps. DC04PRO can achieve 100 steps of adjustment with the volume button. Therefore, using the DC04PRO with an iPhone, will achieve finer volume adjustments.
