Singxer SU02
Singxer SU02
The SU-2 digital interface is a high-performance USB digital audio interface
The microprocessor features the latest ARM Cortex-M4 as the core and is the main control for the USB data exchange. SU-2 uses a custom ultra-low jitter clock system (ACCUSILICON's AS-318B series, which achieves ultra-low jitter at the femtosecond level). A large-capacity FPGA serves as the digital audio data processing core and has a standard USB2.0 input interface. The SU-2 utilizes a diverse output interface, including XLR balanced output AES, coaxial RCA and BNC, I2S interface with HDMI socket output, perfect master clock, and word clock (WCLK) output. SU-2 supports external 10Mhz clock inputs using a common 50 ohm input impedance design.
The SU-2 is not only a USB interface, but it can also be used as an independent master clock center.
1. When used as an independent master clock, it can output a word clock of 44.1K-384K, or output a master clock of 22.5792Mhz-49.152Mhz. (When not connected to USB, it will be used as the master clock device by default)
2. When using an external 10Mhz clock input, it can also be used as a frequency converter, supporting 10Mhz to 44.1K-384K word clock, or output 22.5792Mhz-49.152Mhz master clock.
SU-2 is a new architecture USB interface with huge upgrades from its predecessor.
1. When used as an independent master clock, it can output a word clock of 44.1K-384K, or output a master clock of 22.5792Mhz-49.152Mhz. (When not connected to USB, it will be used as the master clock device by default)
2. When using an external 10Mhz clock input, it can also be used as a frequency converter, supporting 10Mhz to 44.1K-384K word clock, or output 22.5792Mhz-49.152Mhz master clock.
System compatibility:
1. Windows 7, Windows 8, Windows 10; 32/64 bit (special drivers may need to be installed)
2. Native MacOS 10.6 and later, using the system's own driver
3. Native Linux with UAC2 compliant kernel, using the system's own driver, (tested on Ubuntu and Daphile systems, based on the INTEL X86 platform)
4. Android OS 4.2 and above(the device needs to support OTG function). Generally speaking, Android 9.0 and above systems are supported by default. It is recommended to use it with specialized players below 9.0.
I2S interface with HDMI socket output:
1. 3.3V LVDS differential signal;
2. DSD ON signal, 5V power supply (small current), CPLD has been processed inside the MUTE signal, and there is no need to output the MUTE signal;
3. The DSD ON signal can be defined by itself. The DSD ON signal can be arbitrarily output to the PIN 13, 14, 15, 16 pins of the socket.
Flexible I2S and clock output configuration:
1. Switches 1-4 correspond to the PIN13-16 pins of the HDMI socket. Pulling to the ON position will cause the HDMI PIN to function as DSD_ON.
2. Switches 5 and 6 are the modes that configure the clock output: When the switch 5 is OFF, the clock outputs MCLK, and when it is ON, the clock outputs WCK. Switch 6 configures the frequency of MCLK, which is 22.5792M / 24.576M when OFF, and 45.1584M / 49.152M when ON. The configuration of switch 6 is valid for CLK OUT, RJ45-I2S, and HDMI-I2S.
3. Switch 7 can set the left and right channels in DSD mode in I2S.
4. Switch 8 can set the BCLK line sequence in the I2S signal; when OFF, PIN4 is BCLK + and PIN6 is BCLK-.
5. Switch 9 can set the line sequence of LRCLK in I2S signal; when OFF, PIN7 is LRCLK + and PIN9 is LRCLK-.
6. Switch 10 can set the line sequence of DATA in I2S signal; when OFF, PIN1 is DATA + and PIN3 is DATA-.
The SU-2 can be configured via SW switches to suit different I2S standards.
However, as far as we know, HDMI-I2S is different for every manufacturer. For most manufacturers, HDMI-I2S is a proprietary protocol of the manufacturer. Therefore, the SU-2 may not be able to adapt to certain HDMI-I2S machines. In such circumstances, returns will not be possible, so please check your HDMI-I2S compatibility protocols prior to purchasing

Shipping Policy
Which countries do you ship to?
We are generally able to ship to most countries via Express Shipping, and many countries via Standard Shipping. You may clarify this with our team to check whether Standard Shipping is available to your country.
We cannot ship to addresses that are "PO boxes or APO/FPO".
*Note: Generally, we can only do Selected Shipping to India and Russia. We can only do Express Shipping to Africa, Argentina, Hawaii, Kuwait, Mauritius, Montenegro and Sri Lanka, to name a few.
This may be subjected to changes due to unpredictable issues such as Covid, war, and etc.
How much does shipping cost?
We have two shipping methods - Standard Shipping and Express Shipping.
Standard Shipping is free for most countries, while Express Shipping is 15-35USD depending on your country. If your order is over 270USD, Express Shipping is free*.
*This applies for most countries. However, large items such as headphones and desktop DAC/AMPs (e.g. HarmonicDyne G200, MUSICIAN MDP-2, and etc.) are excluded.
Shipping fees exclude import taxes or processing fees that may be applicable for your country. Linsoul is not responsible for such fees. Should you refuse to pay the tax/customs fees, shipping fees will still be deducted from the amount paid for thetwo-way freightcharges. The cost of the freight charges may be more than the amount reflected on your order due to tax and other miscellaneous fees.
Some parcels claimed to be “returned to the seller” may be destroyed by the post office or customs officers when buyers refuse to accept their parcels or fail to pay for their taxes.No refundwill be processed for such cases.Standard Shipping via YunExpress is a tax-inclusive option for some countries.
