Typoed it here, not in the email. I've sent two emails and still haven't gotten an auto-reply.

When I sent an email earlier, it said the server was refusing connections, so I think their email/web provider is (unfortunately as usual) having issues.

Here is what I received from Kingwa on the Gain switch issue :

Quote:

Dear Sandeep,
No, don't need power off the Compass.
Change the gain switch can't shatter the Compass.
It also can't shatter the headphone, if the Compass sense some thing maybe will shatter the headphone, it will shut down the output, then the headphone will be safe. You can try this in your Compass, their will be fine always, I also test change the gain switch very lot times while playing.

Nah, I don't want to pull Kingwa into it. Besides, I don't have enough knowledge to talk to Kingwa about these things.

But looking at the datasheet for the AD1852 I reckon 700pF is about a good enough ballbark figure. Couple OS-CONS, couple WIMAs, couple Cerafines would maybe do the trick.

You seem to be knowledgeable enough.

And I just suggested it, because Kingwa doesn't seem too secretive about his designs (or at all) and encourages feedback from DIY experiments.

In my case it was the gain switch, no doubt about it.
Whatever, everything is working fine now, including that switch, so no issue.

Strange!

I also always lower the Volume Control when unplugging the Headphones too, must be superstition!
