FEATURES OVERLAY
The DMS-2 D-Clock 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’.
Always connect the mains earth to the unit. Use fibre or
plastic washers to prevent the front panel becoming marked
by the mounting bolts.
INSTALLATION
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-2 D-Clock operates from mains voltages between
85 - 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.
