Owners with an Upsampler may prefer to use it to run the DAC at 176.4kS/s. 

•  If necessary, use the 

 button to set the Clock to 

. 

•  Connect one of the Clock outputs to the Word Clock inputs of the transport, the Upsampler and the 

DAC. 

•  Connect an AES cable between the transport’s AES output and the Upsampler’s AES input, select 

that input. 

•  Set the Upsampler to 

. 

• Connect the Upsampler’s 

 & 

 outputs to the DAC’s 

 & 

 inputs and select the DAC’s 

 input. (It may be necessary to turn Dual AES mode on in the menu.) 

•  The transport will automatically slave to the Clock and display 

.  

•  Set the Upsampler to sync to the external word clock. 

•  Use the DAC’s 

 button to set it to 

. 

•  Connect the DAC’s 

 to a power amplifier or preamplifier. 

•  Set the DAC 

 control to a suitable level and play a disc. 

•  Set the Clock’s 

 feature on or off as you prefer. 

 

If you have a GPS receiver or an atomic clock with a 10MHz output, you can lock the Scarlatti Clock to 
it. These sources are even more accurate than the Scarlatti Clock, but note that low jitter and stability 
are more important than absolute accuracy. 

•  Connect your system for DSD or Dual AES as you prefer. 

•  Use another BNC cable to connect the 10MHz output from the external reference to the Scarlatti 

Clock‘s 

 connector. 

•  Open the Clock’s menu and set the 

Coupling

 menu page to 

Bipolar

. The Clock should lock to the 

external reference and display 

. 

•  Set the DAC 

 control to a suitable level and play a disc.
