Product Details


Costa de Gustard U12 digital interface XMOS program complete independent linear power interface 0.1PPM crystal support 32B 384K

U12 uses the company used in professional audio field XMOS latest chip U8, inside there are eight cores, with powerful multi-core multi-thread processing capability, is the industry's very good USB Audio Class 2.0 digital audio solutions.

Increase the screen display, the sampling rate at a glance

Use XMOS programs to support 32B 384khz asynchronous 2.0 (USB recommended that ASIO output)

Using an independent power supply. Built-in sealing ring cattle, multiple sets of multi-level regulation. About the importance of independent power, I believe we all know.

Optimize the design of the audio clock circuit using 0.1PPM precision active crystal to provide a more perfect clock signal to digital audio. Provided for by the two crystals were 44.1 / 88.2 / 176.4 / 352.8Khz and 48/96/192 / 384Khz series rate signal only after the selected clock rate selected work, work another one audio clock stop, put an end to the mutual interference may bring work simultaneously when the two clocks.

A total of four kinds of output: Coaxial (RCA), optical fiber, AES / EBU, IIS (HDMI port)

Coaxial fiber AES / EBU output formats IEC60958 and AES3-r2009 standard limits the maximum support 24Bit / 192kHz; IIS can transmit 32B 384K

Smart switch, USB has a current interface to boot. Interface with the computer switch and switch machine (computer to be set off USB power failure), or unplug the USB cable directly to the shutdown.

Questions & Answers

  • Q: Please tell me if and how the U12 can be used with the X20U, and what benefit I would experience. I love my X20U!
  • A: Hi Steve,it can connect the IIS port, via HDMI line, get a higher quality.Thank you.

  • Q: Hi, would the GUSTARD U12 help the USB performance between a Raspberry pi3 and a USB DAC ? USB on the Raspberry pi seem to be a weak link. If so what would be the best way to connect? Maybe using I2S
  • A: Hi Chris,I2S is better than USB,but the Raspberry pi worse than the computer.Thank you.

  • Q: to connect the gustard u12 in i2s with gustard dac x20, just a normal hdmi cable?
  • A: Hi Alfonso,Yes,a normal hdmi cable is fine.Thank you.

  • Q: Hi, I have a Gustard U12 and recently bought a Gustard X20u (just realized a pro version is comming at the end of the month, would have been nice to kno before byuing). You say the Gustard X20U can play 512 DSD with I2S connection. The pins were inverted when you designed the I2S outputs (and HDMI plug) of both u12 and dacx20u. How can we have the Gustardx20u play DSD512 if the Gustard u12 cannot output more than DSD 128? Do you plan to sell a new usb to I2S compatible for the dac (upgrade to the actual u12 to support DSD 512)? I cannot use another usb I2S converter from another - because the inverted pins of your design - I do not have DIY skills for diyinhk converters and therefore cannot play DSD 512 on my Gustard dac... Another way of doing this would be to change the software of the U12 to made it able to support DSD 512 output to DAC tthrought I2S/HDMI. I bought the 6$ XMOS 3.38 drivers hopping it would work for DSD512, but did not work. What do you suggest me to do to be able to play DSD 512 on the Gustard x20u DAC? I find this pretty frustrating. thanks Jocelyn
  • A: Hi Jocelyn, Thank you for your email. GUSTARD U12 can't up to DSD512. Singxer SU-1 USB digital interface with XMOS XU208 CPLD DSD256 DOP can up to DSD256. Best Regards Kerwin Shenzhenaudio
