This is a NEW Singxer F1 w/aluminum case that is for sale together as a package. It’s NEW condition with no hours of use.Pre-assembled. Manufacturer recommends 500hours of burn in time before you evaluate it’s final sound. Our customers say it will sound Bright when during the initial burn in. The same goes for the Singxer SU-1, a common trait with the Crystek 575 clocks. Personally,I don’t bother listening to it at all until after the break in is finished. I turn on my system and let it run for about 2 weeks straight. This will take the edge off and will relax into it’s final sound.

We want to be upfront and honest to set your expectations before purchasing. Most DDC’s we have owned will have burn in times that are required.

This item will ship free with coupon code “SINGXER”

SingXer F1

Product Details

     F-1 digital interface module, the whole network starting. The first use of the second generation XMOS chip developed high-XU208 USB interface, support firmware upgrade. Self-developed schematics and firmware (including XMOS and CPLD), non-reference design.

The reason why Singxer F-1 is so great is that it primarily uses some of the following TECHNOLOGY :

1. full isolation technology, 150Mbps full-chip isolation, interference can be completely isolated from the PC;

2. source synchronous shaping technology and CPLD technology, I2S signal isolation after the re-shaping; thus eliminating the isolation chip to bring added jitter;

3. the independent development of the system clock, using femtosecond CRYSTEK custom clock, ultra-low phase noise, low jitter.

Product Description:

F-1 digital interface of our team to develop a high-performance USB digital audio interface, using the XMOS latest xCORE-200 series chips. F-1 is the rare use of ultra- low-jitter femtosecond clock digital system interface. F-1 digital interface using standard USB2.0 input interface, while F-1 has a wealth of output interfaces, including coaxial RCA and I2S interfaces.


1. F-1 is the first using the XMOS latest xCORE-200 series of high-end USB digital interface products.New generation XMOS chip, using more advanced processing technology. It’s performance compared to the older U8 chip has doubled, reaching 1000MIPS processing capabilities.

2. it is known, the weight of the core is digital audio algorithms. Our team in the field of digital audio work for many years, at the same time get XMOS FAE support team, we conducted a number of technical improvements and optimization algorithms on the basis of the original firmware.


Each output interface supports sample rates:


176.4kHz, 192KHz, 352.8KHz, 384kHz

[ Wherein I2S out support full sample rate , S / PDIF supports up to 192KHz]

DSD:2.8 MHz (DSD64) – DoP, native

5.6 MHz (DSD128) – DoP, native

11.2 MHz (DSD256) – DoP,native

[ Wherein I2S out support all DSD format , S / PDIF and AES / EBU support DSD64 DOP mode ]

位宽:最高32 bit over I2S output

最高24 bit over S/PDIF

Screw position, I2S pin position is fully compatible with Italy Amanero module

The entire board with three crystal design, all are imported SMD crystal using active crystal. Wherein the audio

Crystal is CRYSTEK CCHD series customized version of the crystal.

Each interface electrical standards:

1 , the USB input socket is a standard USB-B type female, the USB power supply range 4.5V-5.1V ;

2 , the RCA connector outputs standard S / PDIF signal level is 550mV ( access standard load ), the output impedance of 75 ohms;

Design details:

1 , carry out electricity as the mother of the acoustic design concept, pay attention to the power supply circuit design, high-performance, low noise and fast response of the LDO as the main power source. The entire board using 2 independent way of LDO power supply, wherein the clock even partially adopted ADI ‘s ultra low noise LDO , in order to ensure the ultimate output performance laid a solid foundation.

2 , the PCB motherboard with 4 -layer circuit board design, ensure that you have full power and ground plane layer, using the method of high-speed digital design, signal integrity and power integrity of the entire board. The clock signal for special treatment, using package design and precise impedance control, thereby ensuring the signal quality and increase the clock anti-jamming capability. Input and output signals follow a standard design, especially USB high speed signals using a 90 ohm differential impedance control.

System Compatibility:

1, Windows XP, Windows 7, Windows 8; 32/64 bit, you need to install special drivers

2, Native MacOS 10.6 and later, using the system comes with drivers

3, Native Linux with UAC2 compliant kernel, using the system comes with drivers

4, Android OS 4.2 and above, the need to support OTG function.
