Looking for some help with my new JLsounds I2SoverUSB board. I want to make sure i have the I2S configuration and SPDIF configuration set up correctly. I am using an AD1955A DAC chip and so I will need I2S MCLK, BCLK, WCLK, SDAT outputs and SPDIF at the same time. I will only be using this as PCM 44.1-192KHZ
I have downloaded the information sheets from the JLsounds website. for testing I have added the power jumpers as described. the board is recognized by the PC just fine. BUT reading through the datasheet for the jumper configurations. I am a bit confused.
it looks like for I2S I leave J3, J4, J5, J6 open. however. it also says for SPDIF to close J5?
Now I bought this board because the website specifically says it will run both i2S and SPDIF at the same time. So I am little confused on those jumpers.
ALSO there are notes about bit settings and for 24 bit it says to close J3???
I am going to use the JLsounds board to generate the master clock so I should add a jumper at Location "G". BUT on the next page, it talks about all the MCLK configurations. it says that the onboard MCLK should have Jumper "B" closed and "G" open.
so there is some conflicting information on the datasheets. can anyone help??

In my application with the ES9028 all I had to do was jumper J2 and provide power because I only used it for USB input.
A toggle switch or relay connected to J5 could solve that issue, you'd just need to open or close it when switching from USB to SPDIF.
The best advice, though, is to contact JL Sounds by email and ask for clarification. I had a few questions and they were very responsive.
