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) 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 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.
Suggestions for DENAFRIPS DDC & DAC
1. Set DDC i2s pinout to '000'
2. Thereafter, cycle thru the i2s pinout of the DAC (while playing music at low volume):
000 (1X 2X 4X LED off)
001
011
100
101
110
111 (1X 2X 4X LED on)
One of the modes should work. To determine the correct mode, you would need to play the test tone of the L/R channel, in phase and out of phase to confirm the tones are played correctly.
3. Verify PCM44.1/48kHz based tracks are played correctly.
4. Repeat the above for DSD
