STEP-BY-STEP
GUIDE
This section guides you through setting up the unit for basic operation.
Preliminaries
The Menu / Setup Guide sheet details the menu structure and details the two most common set-ups.
For all of the
Word Clock Outputs
and the
Ref Input
, use 75
Ω coax cables fitted with BNC plugs.
Connect the power cable supplied to the power inlet on the Clock rear panel, plug the other end into a
convenient power outlet.
!
Please do not use an excessively heavy or inflexible power cable as this may damage
the power inlet connector.
Press the
Power
button and wait about 30 seconds while the Clock configures itself. The display will
show in sequence:
Scarlatti
and either
44.1Hz
or
48kHz
.
If the unit is likely to be set in an unfamiliar state, you can reset it as follows:
Press the
Menu
button, press the
→
button once, then the
Menu
button again to display the
Clock
Settings
menu. Press the
←
button a few times to highlight the
Factory Reset
menu page. Press the
Menu
button and wait a few seconds while the unit resets itself.
The GOLDEN RULES for using a Master Clock
• The source equipment MUST be locked to the Master Clock.
If it is not, you will either have locking difficulties or hear occasional clicks and the advantages of
using the Clock will be lost.
Some non-dCS CD transports, DAB radios and other equipment do not have a Word Clock Input
and so CANNOT be locked to a Master Clock.
• The clock frequency MUST match the sample rate(s) used in the system.
If it does not, the system cannot lock and the DAC may remain muted. Please check the
manuals for the equipment used in your system.
When the Scarlatti Clock is set to 44.1kHz, it may be used with DSD-based systems, CD
systems without an upsampler running at 44.1kHz or CD systems upsampling to 88.2kS/s or
176.4kS/s Dual AES.
When the Scarlatti Clock is set to 48kHz, it may be used with a DVD player or DAT recorder
fitted with a Word Clock Input running at 48kS/s, or upsampling to 96kS/s Dual AES or 192kS/s
Dual AES.
To make best use of the Scarlatti Clock, all the digital audio units in the chain should be locked to it.
