USING THE dCS ROSSINI MASTER CLOCK FOR THE FIRST TIME
Congratulations on purchasing your dCS Rossini Master 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.
What’s in the box?
Check that the box contains the following items:
•dCS Rossini Master Clock
•Manual
•Power cable
•2x BNC cables
•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.
Positioning the unit
For best sound quality, the units in the Rossini range are designed to be mounted on separate shelves
of a rack, although they may be stacked directly on top of each other if this is absolutely necessary.
Place each unit on a firm, vibration free base, allowing convenient connection to the other parts of
your system. To prevent overheating, we recommend that you leave some free space around the unit
to allow for ventilation.
With all feet screwed fully home, the unit will sit level on a flat surface. If you need to do
any levelling, you can unscrew any of the feet up to 3 complete turns, to give up to 3mm
(1/8”) of height adjustment.

Safety Notice
Your dCS Rossini Master 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.
If you decide to remove safety covers for any reason, disconnect the power cable first.
Note that removing covers voids the warranty.
To maintain protection from electric shock, the unit MUST be connected to mains earth
(ground) via the power cable. Also, unearthed systems do not give the best sonic
performance.
Protect the product from dripping or splashing liquids. Liquid-filled objects such as vases
must not be placed on the product.
This product is not suitable for operation at altitudes above 2000m.
This product is lead-free and complies with the RoHS directive.
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. 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.
We do not recommend the use of mains regenerators. However, if you do wish to use a mains
regenerator with variable voltage and frequency, we recommend that you set the voltage to match
your local voltage and the frequency to either 50Hz or 60Hz ONLY.
!
Damage caused to your Rossini Master Clock by misuse of a mains regenerator or by
a malfunctioning mains regenerator is not covered by the warranty.
Disposal at end-of-life - the symbol indicates that this product should not be treated as
normal household waste. It should be recycled, so please take it to an approved
collection facility.
