Description / iBasso DC07 PRO Hi-Res USB DAC/Amp
A Masterpiece Dongle: THD+N: 0.000098%
The DC07PRO is a dongle that combines iBasso's extensive experience in dongle development and design elements from their audio players. It utilizes advanced technologies to create a dongle with exceptionally low THD+N. The DC07PRO has made significant advancements in its performance, with class leading performance on several metrics.
| THD+N: | 0.000098%（-120.2dB） |
| Dynamic Range | 134dB |
| Noise Floor： |
Single ended: 0.76 uV Balanced: 0.85 uV |
| Output Power | 430mW+430mW @ 32 Ohms |
| Frequency Response | 10Hz-80kHz (-0.5dB） |
DC07PRO’s FPGA System Controller Developed In-House
The DC07PRO utilizes iBasso's FPGA technology, developed in-house. The FPGA integrates audio algorithms and performs as the system controller of the dongle. As the core of the DC07PRO, the FPGA plays the role of signal regeneration and clock synchronization. The FPGA also generates ultra-low jitter clocks for DAC and USB receiver, which can effectively reduce the clock jitter caused by the USB bus.
CS43131x4 Flagship DAC Array
The DC07PRO utilizes four pieces Cirrus Logic flagship CS43131 DAC chips in combination with iBasso's exclusive FPGA technology and experienced circuit design. The results are a comprehensive leap in audio measurements. Measured THD+N by Audio Precision analyser is a remarkable -120.2dB! Utilizing iBasso's exclusive FPGA, the DC07PRO supports DSD512 and PCM 32bit/768kHz.
Impressive Power Consumption with High Power Output
DC07PRO utilizes a synchronous DC-DC converter with a power conversion efficiency of up to 94%. The power consumption of the DC07PRO is as low as 80mA, which is 40% lower than that of DC04PRO, and the output power is increased by 82%! The DAC power supply adopts an ultra-low noise LDO dedicated for analog circuits, with a PSRR (power supply rejection ratio) of up to 100dB to ensure the purity of the power supply.
0.96 Inch OLED for Convenient Operation
The DC07PRO has a 0.96inch OLED screen and is equipped with an ALPS encoder. One can browse and complete all settings using the multi-function knob. Simply rotate and press the multi-function knob to complete volume adjustments, digital filter settings, etc. The DC07PRO also supports the iBasso UAC Android APK, which allows you to control all settings with your Android device.
No APK is required on the iOS side, and all the functions of DC07PRO can be used and enjoyed on iPhone via the multi-function knob.
DAP Like Design with CNC Machining
The shell of the DC07PRO is CNC machined aluminum, with OLED panel on top, and back cover in tempered glass. Additionally, a knob has been strategically positioned on the side. The style and precision exude a sense of luxury and sophistication, reminiscent of high-end DAPs.
32bit/768kHz SPDIF Output
The DC07PRO supports SPDIF output up to 32bit/768kHz. With the DC07PRO, your smartphone also can now be a top tier SPDIF transport.
