ProtoDAC TDA1387 X8 project

[springle19]

Folks

Very happy with my protoDAC build, and great instructions to work to. Lovely, rich, and clear sound thru my 43 year old Rotel 820BX and Tannoy Mercuries. But, by God, was doing the soldering hard work - my eyes are a fraction of what they used to be! 

One minor point. I do hear a minor 'click' thru the speakers when I press 'play' in moode, a fraction of a second before the selected track starts playing. I think this is protoDAC related.  Annoying rather than fundamental, and no evidence the issue persists once the track is up-and-running

Any thoughts on why I have got this and a possible fix?

Best, Simon P

Hi Simon P,

Thank you for the kind words.

I think the click is module related. Probably one chip on the module. The fix is to replace the module. Not an easy thing to do, unless you have excellent desoldering equipment. Do you get a click before each track in the playlist, or just at the beginning of the first track?

Thanks for the prompt reply

The click diagnosis is a bit tricky, at least toggling forwards/backwards in short order (with 4 or 5 seconds per track) using a short test playlist . . .

Under these circs, I get a click (on both left and right channels) at the start of maybe every third of fourth item, but the click does differ in intensity. If I didn't know better, I'd say it sounded like a bit of static or a needle going down on an LP (NOTE: am using test tracks from a flac-ed CD)

Possible soldering issue to revisit/check? If I have to go down the module replacement route, that should be pretty hassle free given I used a mount for the module, so can pop it out.

So far, I can't hear clicks within tracks, only as tracks initiate playing, so I need to keep some proportion . . .

Your thoughts appreciated
