So I bought this equipment from Sure Electronics to work on a project. I've switched directions a bit, and decided to only use part of it but I can't get an answer from Sure Electronics, I'm assuming because of Chinese New Year, and there literally are no instructions with this equipment on their website.

Here's the equipment I want to use:
CS4334 IIS/I2S Decode Board HP amplifier D/A WM8804 S/PDIF Converter Codec DAC
Electric Digital Volume Control Kit Hifi DIY

Here's what I want to know:
Looking at Decode Board and the S/PDIF Codec DAC and the way they connect to each other, they use a "ribbon cable" type connector that uses the ACLK, +5V_CLK, GND, DATA, BCLK, and LRCLK. The Decode Board has one terminal for this connector. The Codec DAC board has 2 terminals, and a hardwired terminal for them.

On the Volume Control Kit, it has a board, and then the encoder knob as separate units. The board connects via the same type of connections as mentioned above. Then the encoder connects via a different cable connection to that board.

My question is, couldn't I connect the Volume Control Kit to that second terminal on the Codec DAC Board and control volume with that? Or would I have to control volume after both boards?

If so I would have to use something like this: Digital Stereo Audio Volume Control Combo Kit after the Decode Board.

If so it would have to go Codec DAC Board (optical toslink input) to Decode Board (RCA Output) to Digital Volume Control Kit (RCA Input)? My concern with this is the amount of connections.

Can someone please advise me on this? I'm going to do some testing, but I'm trying to work it out in my head here at work, and I was hoping someone had some experience with this.

Thank you.
 
As i read in the description of the first postet volume board link

Specially Designed for Audio Amplifier Board

I guess it is not an plug and play solution to use that volume in other setup as on an Audio Amp Board designed for. May be it needs some cable adaption to use in other applications.

Single-end Audio Signal Input and Output

That mean it could attunate single end line signals in general. May be between an DAC and AMP.

Better solution would be the second volume kit, more plug and play via chinch connections.
