The DMS-4 is designed for standard 19" rack mounting and occupies 1U of rack space. Avoid mounting the unit directly
above power amplifiers or power supplies that radiate significant amounts of heat.
If the unit is to be used in a mobile situation, it is strongly recommended that the rear of the unit is supported in the
carrying rack to avoid bending the front panel rack mounting ‘ears’.
Use fibre or plastic washers to prevent the front panel becoming marked by the mounting bolts.
The unit will be supplied with a power cable suitable for domestic power outlets in your country. For your own safety it
is important that you use this cable. The unit should always be connected to the mains supply earth using this cable.
Powered by a universal switch mode power supply, the  DMS-4 M-Clock Lite operates from mains voltages between 85
to 250v, eliminating the need to make any changes when touring and allowing the unit to remain fully operational during
large fluctuations in the mains power supply.

The DMS-4 is fitted with a mains fuse that conforms to the IEC127-2
standard and is rated at T315mA. If the fuse blows it must be replaced
with one of identical type and value. To do so remove the mains cable
from the IEC connector and open the drawer that is located just
below, replace the fuse, close the drawer and re-attach the mains
cable.

Word Clock

Use only good quality 75

 digital or video coax (not aerial downlead) cable for the word-clock signals, terminated with

the correct type of 75

 BNC connectors - inferior cables will introduce jitter and will completely undermine the performance

benefits which might be achieved by using a master clock in the first place!
