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.
