Monarchy Audio DIP Super Drive

[JohanH]

Hello all,

I´m considering buying a Monarchy Audio DIP Super Drive. (Can get one for relatively little money)

Can anybody tell me what is inside:
maybe even a schematic?

Thanks in advance.

Most initial DIPs worked like this, which can be bettered by adding a secondary VCXO with much lower cut off frequency in the PLL loop, and reclocking the SPDIF output.

Thanks guys,

that is very helpful.

So, are these things any effective in what they are supposed to do: reduce jitter?

I do not know. I have never tried one !!

there are plenty of reviews on GOOGLE.

Thanks Andy,

of course I already found those.
I was hoping for an answer on why these devices are found to be effective. Do they actually reduce jitter or can the positive effects be attributed to other mechanisms?

I think I'll bite the bullet on this one and just buy the thing.

Hi

They do reduce jitter, but not as effective as possible. If you want to drastically reduce the jitter, you need a PLL with truly low filter cutoff frequency.
