FIRMWARE UPDATE

DENAFRIPS all-new USB DAC solution supports off-site firmware update. The update includes updating of the USB MCU firmware and the core DSP FPGA firmware. 

 

The procedures are as described in the following. It can be done in Windows 10 Operating System over the USB port by a computer savvy person. Should you need further assistance, please contact us.

DISABLE WINDOWS SIGNED DRIVER ENFORCEMENT

Windows 10 enforces driver signatures by default. This can be disabled to install drivers that are not digitally signed. Use the following steps to disable driver signature enforcement.

  1. Click the Start Start menu and select Settings.

  2. Click Update and Security.

  3. Click on Recovery.

  4. Click Restart now under Advanced Startup.

  5. Click Troubleshoot.

  6. Click Advanced options.

  7. Click Startup Settings.

  8. Click on Restart.


On the Startup Settings screen press 7 or F7 to disable driver signature enforcement. 

 

Your computer will restart and you will be able to install non-digitally signed drivers. If you restart your computer again the driver signature enforcement will be re-enabled.

WHAT IS REQUIRED?

You would need the following items in order to proceed:

  1. A Windows 10 PC/Laptop with USB port

  2. Standard USB Cable

  3. Internet Connection (To download the driver and firmware packages)

  4. DENAFRIPS DAC

WARNING 

Please note that flashing the incorrect firmware will brick the product. Please do not use any firmware obtain from unknown sources. 

  • FIFO Buffer & Reclocking Latency
    DENAFRIPS DDC/DAC uses Adaptive FIFO Buffer, and Reclocking. These techniques yield excellent jitter rejection, however, the variable latency is inevitable. The latency may have an effect to video/audio lip sync, commonly known as lip-sync. If you plan to use DDC/DAC mainly for gaming/video streaming, it may not be suitable. If you use the DDC/DAC purely for stereo music listening, it would work perfectly. Some TVs come with a feature to adjust the lip sync delay. Example: https://www.sony.com/electronics/support/articles/00026069 If the TV comes with such a setting, it will be a good mitigating option to correct the lip sync for TV/movies. If you use USB input directly to the DAC, the latency is minimal, and the lip sync should not appear on USB input.

  • Quick Start Guide
    ​Connect the AC Mains to the DAC​ power socket inlet Switch on the power. Once the AC supply is on, the DAC will be in Standby mode (Standby LED shall be on) Press on the Standby button once to turn on the DAC (Standby LED shall switch off) Select USB Input, the respective LED shall switch on Note: DENAFRIPS DAC USB input require the USB cable to carry +5V supply. The DAC uses the USB cable power supply as logical input to switch on the USB receiver chip via the internal Linear Power Supply. In the event of USB input is not selected, the USB receiver chip supply will be cut off to reduce possible interference of USB to the rest of the Input signals Boot up the computer, i.e. Laptop / Desktop / Streamer Connects the USB cable from the computer to the DAC Unzip the USB Driver Execute the driver installation, follow the on-screen instructions USB DAC shall be detected and driver installation will proceed automatically Select USB DAC as output source (vary depending on the software used, i.e. Roon, JRiver, JPlay, Foobar etc) Play your favorite music, and, Enjoy the music!​

  • USB2.0 Cable
    DENAFRIPS DAC USB receiver is powered by its internal regulated, low noise, low ripple, high speed linear power supply. However, it needs the USB cable to supply the +5vdc as a logic signal to trigger the internal power supply to the USB receiver. This design is intentional for best sound quality consideration. Please use a good quality USB2.0 Type A/B cable less than or equal to <= 6ft/2m length for best results.
  • I²S Connection
    I²S I²S has no industry standard. If you would like to use the I²S connection, the I²S pinout matching with the source (DDC/Transport/Streamer) and DAC has to be configured correctly. Mismatch of I²S pinout may result in static/noise output. The excessive noise output level may damage the loudspeakers/headphone drivers. Suggestion of I²S matching with the source, i.e. DDC/Transport/Streamer ​ 1. Connect the I²S cable (good quality HDMI cable <3ft/1m) 2. Turn down the volume (audible, minimal) 3. Play a familiar music (PCM first, followed by DSD) 4. Run through the I²S setting of the DAC, 000-111 5. One of the modes should match with the source for both PCM and DSD playback. ​ It's recommended to go through the Audio Tone Test to make sure the L/R channel, in phase/out of phase correctness. Warning Please note that the RJ45/HDMI ports of DENAFRIPS DDC/DAC are not typical network/multimedia RJ45/HDMI ports. They are purpose-built I²S ports. Please do not connect it to the typical multimedia HDMI port (i.e. Bluray player/TV etc) / Ethernet network. Need help? Please reach out to us at support@denafrips.com . We are happy to assist you.
