Digital clocking question for RH

Atul Kanagat -- Thu, 04/07/2011 - 07:21

My Scarlatti clock has two options, 44.1KHz and 48KHz. Are these sufficient for clocking 88.2, 96, 176.4, and 192 KHz, all multiples of 44.1 and 48. Do I need a clock those frequencies specifically?

Atul, the short answer is yes, you will need to clock all the digital equipment you use in the chain to the correct frequency. There are ways around this but really if you're doing a lot of 96k or 192k playback you should think about a new clock.
I hope this helps,

Hi Atul - All dCS components use what's called a base rate clock either 44.1 or 48 kHz. You do not need to specify a specific higher frequency for rates like 88.2, 96, 176.4, or 192 kHz. The dCS components use clock multiplication.
If you are using a non-dCS DAC that receives this clock signal or are sending clock to an audio card such as a Lynx AES16 then the Scarlatti clock may not work as desired. RME audio cards can use clock multiplication unlike Lynx cards.
