SING THE 

dCS

 

Puccini U-Clock

 FOR THE FIRST TIME

 

Congratulations on purchasing your 

dCS Puccini U-Clock

.  

Before using your unit, please read this section and the Step by Step Guide. This will enable you to 
set the unit up quickly and safely with your hi-fi system. 

The 

U-Clock

 is a combination of a system clock with a sophisticated USB to SPDIF converter. You can 

use it as a clock or a converter or both together. Locking your digital system to the 

U-Clock

 reduces 

jitter and improves the sonic performance. Use the converter as a gateway for a PC, Mac or sound 
server to connect computer-based music into your system, while avoiding the high levels of jitter and 
other compromises commonly found in such sources. 

The 

U-clock

 is simpler than most other 

dCS

 products, it does not feature remote control or software 

that can be updated by the user.  

 

 What’s in the box? 

Check that the box contains the following items: 

 

dCS Puccini U-Clock 

 Manual 

 Power 

cable 

 USB 

cable 

 BNC 

cable 

 spare 

fuses 

 

Notify your dealer as soon as possible if anything is missing or damaged. We suggest that you retain 
the original packaging for possible future use. If this is not possible, replacement packaging can be 
ordered from 

dCS

 or our distributors. Details can be found on our web site at 

www.dcsltd.co.uk

 

 Safety Notice 

Your 

dCS Puccini U-Clock

 contains no user serviceable parts. 

DO NOT 

attempt to open the case as 

there are potentially dangerous voltages present inside. In the event of the unit developing a fault, 
please contact your dealer in the first instance. 

 

 Mains Voltage Setting 

Before connecting the power cable to the unit for the first time, please check that it has been set to the 
correct operating voltage for your mains supply. The unit’s voltage setting is shown on the serial 
number label on the bottom cover. If this does not match your local supply voltage, DO NOT attempt 
to use the unit. Contact your dealer to have the unit reset. Using the unit with the wrong mains setting 
for your local supply may result in serious damage to the unit and will invalidate the warranty. Do not 
attempt to reset the voltage yourself. 

 

 Power Cables 

If you wish to use a power cable other than the one supplied, please ensure that it is a good fit to the 
mains inlet, and is not so heavy and inflexible as to place strain on the mains inlet.
