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 75Ω 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.
