Did anyone tried to connect a 10Mhz clock directly on the Hapi wordclock input?
I know that Hapi accepts from 44.1Khz to 394Khz as input on the BNC.
What if reference 10Mhz clock is given? Anyone did it give a try?
Thank you

Re: Feeding the 10Mhz clock as Hapi wordclock input
Hi robertopisa,
I am using an Mutec MC3+USB and Ref-10 SE clock with Hapi MK1. There is a noticeable difference between the internal and external clocks. At the moment, I'm using 44.1khz clock source.

Hello Vinod,
this forum is not very active, so I forgot to check the messages after a while and I did not see your reply.
I first apologize and then thank you for replying
I was not very clear with my question: what if I directly feed the Hapi with 10Mhz as external World Clock?
Does it accept it anyway?
Kids regards

Re: Feeding the 10Mhz clock as Hapi wordclock input
10mHz in won't work, and is pointless. Also, 10mHz is not an integer multiple of any common audio sampling frequency.
If you have a clock with an internal 10mHz master clock, and conventional outputs at audio sampling rates, you might hear a difference, but it may not be an improvement. You are adding 3 PLL's to the process when you use rubidium clocks. You might be better off with a crystal clock. Maybe Black Lion Audio, provided that their clock is a real crystal and not a frequency synthesizer.

Re: Feeding the 10Mhz clock as Hapi wordclock input
At the end, I employed a Grimm CC2 master clock, which can work with Merging Hapi for all sample rates as follows. I use just the two base FS = 44.1k and 48k from Grimm (Setup->I/O->Sync->WCK), and multiplies them by 1x, 2x, 4x, 8x internally in Hapi as follows: just go to Setup->Formats->Auto and disable auto sampling mode. At this point, change manually Setup->Formats->SampleRate as your prefer. FS = 44.1k in Grimm is useful for 44.1, 88.2, 176.4, 352.8, and DXD/DSD in Hapi, while FS = 48k for the remaining ones.
